Digital Object
type: Class
notation: D1
comment: This class comprises identifiable immaterial items that can be represented as sets of bit sequences, such as data sets, e-texts, images, audio or video items, software, etc., and are documented as single units. Any aggregation of instances of D1 Digital Object into a whole treated as single unit is also regarded as an instance of D1 Digital Object. This means that for instance, the content of a DVD, an XML file on it, and an element of this file, are regarded as distinct instances of D1 Digital Object, mutually related by the P106 is composed of (forms part of) property. A D1 Digital Object does not depend on a specific physical carrier, and it can exist on one or more carriers simultaneously.

Digitization Process
type: Class
notation: D2
comment: This class comprises events that result in the creation of instances of D9 Data Object that represent the appearance and/or form of an instance of E18 Physical Thing such as paper documents, statues, buildings, paintings, etc. A particular case is the analogue-to-digital conversion of audiovisual material. This class represents the transition from a material thing to an immaterial representation of it. The characteristic subsequent processing steps on digital objects are regarded as instances of D3 Formal Derivation.
subclass of: Digital Measurement Event

Formal Derivation
type: Class
notation: D3
comment: This class comprises events that result in the creation of a D1 Digital Object from another one following a deterministic algorithm, such that the resulting instance of digital object shares representative properties with the original object. In other words, this class describes the transition from an immaterial object referred to by property L21 used as derivation source (was derivation source for) to another immaterial object referred to by property L22 created derivative (was derivative created by) preserving the representation of some things but in a different form. Characteristic examples are colour corrections, contrast changes and resizing of images.
subclass of: Software Execution

Digital Machine Event
type: Class
notation: D7
comment: This class comprises events that happen on physical digital devices following a human activity that intentionally caused its immediate or delayed initiation and results in the creation of a new instance of D1 Digital Object on behalf of the human actor. The input of a D7 Digital Machine Event may be parameter settings and/or data to be processed. Some D7 Digital Machine Events may form part of a wider E65 Creation event. In this case, all machine output of the partial events is regarded as creation of the overall activity.
subclass of: Modification
subclass of: Creation

Digital Device
type: Class
notation: D8
comment: This class comprises identifiable material items such as computers, scanners, cameras, etc. that have the capability to process or produce instances of D1 Digital Object.
subclass of: Man-Made Object

Data Object
type: Class
notation: D9
comment: This class comprises instances of D1 Digital Object that are the direct result of a digital measurement or a formal derivative of it, containing quantitative properties of some physical things or other constellations of matter.
subclass of: Digital Object
subclass of: Dimension

Software Execution
type: Class
notation: D10
comment: This class comprises events by which a digital device runs a software program or a series of computing operations on a digital object as a single task, which is completely determined by its digital input, the software and the generic properties of the device.
subclass of: Digital Machine Event

Digital Measurement Event
type: Class
notation: D11
comment: This class comprises actions measuring physical properties using a digital device, that are determined by a systematic procedure and creates an instance of D9 Data Object, which is stored on an instance of D13 Digital Information Carrier. In contrast to instances of D10 Software Execution, environmental factors have an intended influence on the outcome of an instance of D11 Digital Measurement Event. Measurement devices may include running distinct software, such as the RAW to JPEG conversion in digital cameras. In this case, the event is regarded as instance of both classes, D10 Software Execution and D11 Digital Measurement Event.
subclass of: Digital Machine Event
subclass of: Measurement

Data Transfer Event
type: Class
notation: D12
comment: This class comprises events that transfer a digital object from one digital carrier to another. Normally, the digital object remains the same. If in general or by observation the transfer implies or has implied some data corruption, the change of the digital objects may be documented distinguishing input and output rather than instantiating the property L14 transferred (was transferred by).
subclass of: Digital Machine Event

Digital Information Carrier
type: Class
notation: D13
comment: This class comprises all instances of E84 Information Carrier that are explicitly designed to be used as persistent digital physical carriers of instances of D1 Digital Object. A D13 Digital Information Carrier may or may not contain information, e.g., an empty diskette.

Software
type: Class
notation: D14
comment: This class comprises software codes, computer programs, procedures and functions that are used to operate a system of digital objects.
subclass of: Digital Object

Person Name
type: Class
notation: D21
comment: This class comprises the proper noun name that identifies a person that acts as an entity.

Room
type: Class
notation: D23
comment: This class comprises a small scale space that contains manipulable objects and retains the bodily experiences of how people assimilate image schemata.

Annotation Object
type: Class
notation: D29
comment: This class comprises objects that make propositions about other artefacts.Instances of this class are not the attributes themselves, by which things are annotated, but represent the connection between the concepts related in a proposition, and the activities of creation, modification and deletion.This class is specialized by appropriate subclasses to express more specific relationships between annotated things, such as knowledge object, same as etc.

Annotation Event
type: Class
notation: D30
comment: This class comprises events that describe the creation of associations (“Annotation Objects”) between objects or areas of objects of the Repository, with other objects or regions or persons, places, events. It is the event that creates the Annotation Object.
subclass of: Creation

Area
type: Class
notation: D35
comment: This class describes a part (of any shape or size) of interest in basically any media object stored in the Object Repository, i.e., a text, an image, a video or a 3D model. It points to content consisting of just a portion or area of a file. In some contexts, however, the area can also point to content represented by an integral (i.e., proper) file. It is equal to the METS AREA element.
subclass of: Digital Object

CRM Entity
type: Class
notation: E1
comment: This class comprises all things in the universe of discourse of the CIDOC Conceptual Reference Model. It is an abstract concept providing for three general properties: Identification by name or appellation, and in particular by a preferred identifier Classification by type, allowing further refinement of the specific subclass an instance belongs to Attachment of free text for the expression of anything not captured by formal properties With the exception of E59 Primitive Value, all other classes within the CRM are directly or indirectly specialisations of E1 CRM Entity.
subclass of: Thing

Temporal Entity
type: Class
notation: E2
comment: This class comprises all phenomena, such as the instances of E4 Periods, E5 Events and states, which happen over a limited extent in time. This extent in time must be contiguous, i.e., without gaps. In case the defining kinds of phenomena for an instance of E2 Temporal Entity cease to happen, and occur later again at another time, we regard that the former E2 Temporal Entity has ended and a new instance has come into existence. In more intuitive terms, the same event cannot happen twice. In some contexts, these are also called perdurants. This class is disjoint from E77 Persistent Item. This is an abstract class and has no direct instances. E2 Temporal Entity is specialized into E4 Period, which applies to a particular geographic area (defined with a greater or lesser degree of precision), and E3 Condition State, which applies to instances of E18 Physical Thing.
subclass of: CRM Entity

Period
type: Class
notation: E4
comment: This class comprises sets of coherent phenomena or cultural manifestations occurring in time and space. It is the social or physical coherence of these phenomena that identify an E4 Period and not the associated spatiotemporal extent. This extent is only the "ground" or space in an abstract physical sense that the actual process of growth, spread and retreat has covered. Consequently, different periods can overlap and coexist in time and space, such as when a nomadic culture exists in the same area and time as a sedentary culture. This also means that overlapping land use rights, common among first nations, amounts to overlapping periods. Often, this class is used to describe prehistoric or historic periods such as the "Neolithic Period", the "Ming Dynasty" or the "McCarthy Era", but also geopolitical units and activities of settlements are regarded as special cases of E4 Period. However, there are no assumptions about the scale of the associated phenomena. In particular all events are seen as synthetic processes consisting of coherent phenomena. Therefore E4 Period is a superclass of E5 Event. For example, a modern clinical E67 Birth can be seen as both an atomic E5 Event and as an E4 Period that consists of multiple activities performed by multiple instances of E39 Actor. As the actual extent of an E4 Period in spacetime we regard the trajectories of the participating physical things during their participation in an instance of E4 Period. This includes the open spaces via which these things have interacted and the spaces by which they had the potential to interact during that period or event in the way defined by the type of the respective period or event. Examples include the air in a meeting room transferring the voices of the participants. Since these phenomena are fuzzy, we assume the spatiotemporal extent to be contiguous, except for cases of phenomena spreading out over islands or other separated areas, including geopolitical units distributed over disconnec…
subclass of: Temporal Entity
subclass of: Spacetime Volume

Event
type: Class
notation: E5
comment: This class comprises changes of states in cultural, social or physical systems, regardless of scale, brought about by a series or group of coherent physical, cultural, technological or legal phenomena. Such changes of state will affect instances of E77 Persistent Item or its subclasses. The distinction between an E5 Event and an E4 Period is partly a question of the scale of observation. Viewed at a coarse level of detail, an E5 Event is an ‘instantaneous’ change of state. At a fine level, the E5 Event can be analysed into its component phenomena within a space and time frame, and as such can be seen as an E4 Period. The reverse is not necessarily the case: not all instances of E4 Period give rise to a noteworthy change of state.
subclass of: Period

Activity
type: Class
notation: E7
comment: This class comprises actions intentionally carried out by instances of E39 Actor that result in changes of state in the cultural, social, or physical systems documented. This notion includes complex, composite and long-lasting actions such as the building of a settlement or a war, as well as simple, short-lived actions such as the opening of a door.
subclass of: Event

Modification
type: Class
notation: E11
comment: This class comprises all instances of E7 Activity that create, alter or change E24 Physical Man-Made Thing. This class includes the production of an item from raw materials, and other so far undocumented objects, and the preventive treatment or restoration of an object for conservation. Since the distinction between modification and production is not always clear, modification is regarded as the more generally applicable concept. This implies that some items may be consumed or destroyed in a Modification, and that others may be produced as a result of it. An event should also be documented using E81 Transformation if it results in the destruction of one or more objects and the simultaneous production of others using parts or material from the originals. In this case, the new items have separate identities. If the instance of the E29 Design or Procedure utilized for the modification prescribes the use of specific materials, they should be documented using property P68 foresees use of (use foreseen by): E57 Material of E29 Design or Procedure, rather than via P126 employed (was employed in): E57 Material.
subclass of: Activity

Attribute Assignment
type: Class
notation: E13
comment: This class comprises the actions of making assertions about properties of an object or any relation between two items or concepts. This class allows the documentation of how the respective assignment came about, and whose opinion it was. All the attributes or properties assigned in such an action can also be seen as directly attached to the respective item or concept, possibly as a collection of contradictory values. All cases of properties in this model that are also described indirectly through an action are characterised as "short cuts" of this action. This redundant modelling of two alternative views is preferred because many implementations may have good reasons to model either the action or the short cut, and the relation between both alternatives can be captured by simple rules. In particular, the class describes the actions of people making propositions and statements during certain museum procedures, e.g. the person and date when a condition statement was made, an identifier was assigned, the museum object was measured, etc. Which kinds of such assignments and statements need to be documented explicitly in structures of a schema rather than free text, depends on if this information should be accessible by structured queries.
subclass of: Activity

Measurement
type: Class
notation: E16
comment: This class comprises actions measuring physical properties and other values that can be determined by a systematic procedure. Examples include measuring the monetary value of a collection of coins or the running time of a specific video cassette. The E16 Measurement may use simple counting or tools, such as yardsticks or radiation detection devices. The interest is in the method and care applied, so that the reliability of the result may be judged at a later stage, or research continued on the associated documents. The date of the event is important for dimensions, which may change value over time, such as the length of an object subject to shrinkage. Details of methods and devices are best handled as free text, whereas basic techniques such as "carbon 14 dating" should be encoded using P2 has type (is type of:) E55 Type.
subclass of: Attribute Assignment

Physical Thing
type: Class
notation: E18
comment: This class comprises all persistent physical items with a relatively stable form, man-made or natural. Depending on the existence of natural boundaries of such things, the CRM distinguishes the instances of E19 Physical Object from instances of E26 Physical Feature, such as holes, rivers, pieces of land etc. Most instances of E19 Physical Object can be moved (if not too heavy), whereas features are integral to the surrounding matter. An instance of E18 Physical Thing occupies not only a particular geometric space, but in the course of its existence it also forms a trajectory through spacetime, which occupies a real, that is phenomenal, volume in spacetime. We include in the occupied space the space filled by the matter of the physical thing and all its inner spaces, such as the interior of a box. Physical things consisting of aggregations of physically unconnected objects, such as a set of chessmen, occupy a number of individually contiguous spacetime volumes equal to the number of unconnected objects that constitute the set. We model E18 Physical Thing to be a subclass of E72 Legal Object and of E92 Spacetime volume. The latter is intended as a phenomenal spacetime volume as defined in CRMgeo (Doerr and Hiebel 2013). By virtue of this multiple inheritance we can discuss the physical extent of an E18 Physical Thing without representing each instance of it together with an instance of its associated spacetime volume. This model combines two quite different kinds of substance: an instance of E18 Physical Thing is matter while a spacetime volume is an aggregation of points in spacetime. However, the real spatiotemporal extent of an instance of E18 Physical Thing is regarded to be unique to it, due to all its details and fuzziness; its identity and existence depends uniquely on the identity of the instance of E18 Physical Thing. Therefore this multiple inheritance is unambiguous and effective and furthermore corresponds to the intuitions of natural language. The CIDOC C…

subclass of: Spacetime Volume

Physical Object
type: Class
notation: E19
comment: This class comprises items of a material nature that are units for documentation and have physical boundaries that separate them completely in an objective way from other objects. The class also includes all aggregates of objects made for functional purposes of whatever kind, independent of physical coherence, such as a set of chessmen. Typically, instances of E19 Physical Object can be moved (if not too heavy). In some contexts, such objects, except for aggregates, are also called “bona fide objects” (Smith Varzi, 2000, pp.401-420), i.e. naturally defined objects. The decision as to what is documented as a complete item, rather than by its parts or components, may be a purely administrative decision or may be a result of the order in which the item was acquired.
subclass of: Physical Thing

Biological Object
type: Class
notation: E20
comment: This class comprises individual items of a material nature, which live, have lived or are natural products of or from living organisms. Artificial objects that incorporate biological elements, such as Victorian butterfly frames, can be documented as both instances of E20 Biological Object and E22 Man-Made Object.
subclass of: Physical Object

Person
type: Class
notation: E21
comment: This class comprises real persons who live or are assumed to have lived. Legendary figures that may have existed, such as Ulysses and King Arthur, fall into this class if the documentation refers to them as historical figures. In cases where doubt exists as to whether several persons are in fact identical, multiple instances can be created and linked to indicate their relationship. The CRM does not propose a specific form to support reasoning about possible identity.
subclass of: Biological Object
subclass of: Actor

Man-Made Object
type: Class
notation: E22
comment: This class comprises physical objects purposely created by human activity. No assumptions are made as to the extent of modification required to justify regarding an object as man-made. For example, an inscribed piece of rock or a preserved butterfly are both regarded as instances of E22 Man-Made Object.
subclass of: Physical Object
subclass of: Physical Man-Made Thing

Physical Man-Made Thing
type: Class
notation: E24
comment: This class comprises all persistent physical items that are purposely created by human activity. This class comprises man-made objects, such as a swords, and man-made features, such as rock art. No assumptions are made as to the extent of modification required to justify regarding an object as man-made. For example, a “cup and ring” carving on bedrock is regarded as instance of E24 Physical Man-Made Thing.
subclass of: Physical Thing
subclass of: Man-Made Thing

Conceptual Object
type: Class
notation: E28
comment: This class comprises non-material products of our minds and other human produced data that have become objects of a discourse about their identity, circumstances of creation or historical implication. The production of such information may have been supported by the use of technical devices such as cameras or computers. Characteristically, instances of this class are created, invented or thought by someone, and then may be documented or communicated between persons. Instances of E28 Conceptual Object have the ability to exist on more than one particular carrier at the same time, such as paper, electronic signals, marks, audio media, paintings, photos, human memories, etc. They cannot be destroyed. They exist as long as they can be found on at least one carrier or in at least one human memory. Their existence ends when the last carrier and the last memory are lost.
subclass of: Man-Made Thing

Actor
type: Class
notation: E39
comment: This class comprises people, either individually or in groups, who have the potential to perform intentional actions of kinds for which someone may be held responsible. The CRM does not attempt to model the inadvertent actions of such actors. Individual people should be documented as instances of E21 Person, whereas groups should be documented as instances of either E74 Group or its subclass E40 Legal Body.
subclass of: Persistent Item

Legal Body
type: Class
notation: E40
comment: This class comprises institutions or groups of people that have obtained a legal recognition as a group and can act collectively as agents. This means that they can perform actions, own property, create or destroy things and can be held collectively responsible for their actions like individual people. The term 'personne morale' is often used for this in French.
subclass of: Group

Time-Span
type: Class
notation: E52
comment: This class comprises abstract temporal extents, in the sense of Galilean physics, having a beginning, an end and a duration. Time Span has no other semantic connotations. Time-Spans are used to define the temporal extent of instances of E4 Period, E5 Event and any other phenomena valid for a certain time. An E52 Time-Span may be identified by one or more instances of E49 Time Appellation. Since our knowledge of history is imperfect, instances of E52 Time-Span can best be considered as approximations of the actual Time-Spans of temporal entities. The properties of E52 Time-Span are intended to allow these approximations to be expressed precisely. An extreme case of approximation, might, for example, define an E52 Time-Span having unknown beginning, end and duration. Used as a common E52 Time-Span for two events, it would nevertheless define them as being simultaneous, even if nothing else was known. Automatic processing and querying of instances of E52 Time-Span is facilitated if data can be parsed into an E61 Time Primitive.
subclass of: CRM Entity

Dimension
type: Class
notation: E54
comment: This class comprises quantifiable properties that can be measured by some calibrated means and can be approximated by values, i.e. points or regions in a mathematical or conceptual space, such as natural or real numbers, RGB values etc. An instance of E54 Dimension represents the true quantity, independent from its numerical approximation, e.g. in inches or in cm. The properties of the class E54 Dimension allow for expressing the numerical approximation of the values of an instance of E54 Dimension. If the true values belong to a non-discrete space, such as spatial distances, it is recommended to record them as approximations by intervals or regions of indeterminacy enclosing the assumed true values. For instance, a length of 5 cm may be recorded as 4.5-5.5 cm, according to the precision of the respective observation. Note, that interoperability of values described in different units depends critically on the representation as value regions. Numerical approximations in archaic instances of E58 Measurement Unit used in historical records should be preserved. Equivalents corresponding to current knowledge should be recorded as additional instances of E54 Dimension as appropriate.
subclass of: CRM Entity

Type
type: Class
notation: E55
comment: This class comprises concepts denoted by terms from thesauri and controlled vocabularies used to characterize and classify instances of CRM classes. Instances of E55 Type represent concepts in contrast to instances of E41 Appellation which are used to name instances of CRM classes. E55 Type is the CRM’s interface to domain specific ontologies and thesauri. These can be represented in the CRM as subclasses of E55 Type, forming hierarchies of terms, i.e. instances of E55 Type linked via P127 has broader term (has narrower term). Such hierarchies may be extended with additional properties.
subclass of: Conceptual Object

Primitive Value
type: Class
notation: E59
comment: This class comprises values of primitive data types of programming languages or database management systems and data types composed of such values used as documentation elements, as well as their mathematical abstractions.They are not considered as elements of the universe of discourse this model aims at defining and analysing. Rather, they play the role of a symbolic interface between the scope of this model and the world of mathematical and computational manipulations and the symbolic objects they define and handle.In particular they comprise lexical forms encoded as "strings" or series of characters and symbols based on encoding schemes (characterised by being a limited subset of the respective mathematical abstractions) such as UNICODE and values of datatypes that can be encoded in a lexical form, including quantitative specifications of time-spans and geometry. They have in common that instances of E59 Primitive Value define themselves by virtue of their encoded value, regardless the nature of their mathematical abstractions.Therefore they must not be represented in an implementation by a universal identifier associated with a content model of different identity. In a concrete application, it is recommended that the primitive value system from a chosen implementation platform and/or data definition language be used to substitute for this class and its subclasses.
subclass of: Thing

Number
type: Class
notation: E60
comment: This class comprises any encoding of computable (algebraic) values such as integers, real numbers, complex numbers, vectors, tensors etc., including intervals of these values to express limited precision. Numbers are fundamentally distinct from identifiers in continua, such as instances of E50 Date and E47 Spatial Coordinate, even though their encoding may be similar. Instances of E60 Number can be combined with each other in algebraic operations to yield other instances of E60 Number, e.g., 1+1=2. Identifiers in continua may be combined with numbers expressing distances to yield new identifiers, e.g., 1924-01-31 + 2 days = 1924-02-02. Cf. E54 Dimension
subclass of: Primitive Value

Time Primitive
type: Class
notation: E61
comment: This class comprises instances of E59 Primitive Value for time that should be implemented with appropriate validation, precision and interval logic to express date ranges relevant to cultural documentation. E61 Time Primitive is not further elaborated upon within the model.
subclass of: Primitive Value

String
type: Class
notation: E62
comment: This class comprises the instances of E59 Primitive Values used for documentation such as free text strings, bitmaps, vector graphics, etc. E62 String is not further elaborated upon within the model
subclass of: Primitive Value

Beginning of Existence
type: Class
notation: E63
comment: This class comprises events that bring into existence any E77 Persistent Item. It may be used for temporal reasoning about things (intellectual products, physical items, groups of people, living beings) beginning to exist; it serves as a hook for determination of a terminus post quem and ante quem.
subclass of: Event

Creation
type: Class
notation: E65
comment: This class comprises events that result in the creation of conceptual items or immaterial products, such as legends, poems, texts, music, images, movies, laws, types etc.
subclass of: Activity
subclass of: Beginning of Existence

Thing
type: Class
notation: E70
comment: This general class comprises discrete, identifiable, instances of E77 Persistent Item that are documented as single units, that either consist of matter or depend on being carried by matter and are characterized by relative stability. They may be intellectual products or physical things. They may for instance have a solid physical form, an electronic encoding, or they may be a logical concept or structure.
subclass of: Persistent Item

Man-Made Thing
type: Class
notation: E71
comment: This class comprises discrete, identifiable man-made items that are documented as single units. These items are either intellectual products or man-made physical things, and are characterized by relative stability. They may for instance have a solid physical form, an electronic encoding, or they may be logical concepts or structures.
subclass of: Thing

Legal Object
type: Class
notation: E72
comment: This class comprises those material or immaterial items to which instances of E30 Right, such as the right of ownership or use, can be applied. This is true for all E18 Physical Thing. In the case of instances of E28 Conceptual Object, however, the identity of the E28 Conceptual Object or the method of its use may be too ambiguous to reliably establish instances of E30 Right, as in the case of taxa and inspirations. Ownership of corporations is currently regarded as out of scope of the CRM.
subclass of: Thing

Group
type: Class
notation: E74
comment: This class comprises any gatherings or organizations of E39 Actors that act collectively or in a similar way due to any form of unifying relationship. In the wider sense this class also comprises official positions which used to be regarded in certain contexts as one actor, independent of the current holder of the office, such as the president of a country. In such cases, it may happen that the Group never had more than one member. A joint pseudonym (i.e., a name that seems indicative of an individual but that is actually used as a persona by two or more people) is a particular case of E74 Group. A gathering of people becomes an E74 Group when it exhibits organizational characteristics usually typified by a set of ideas or beliefs held in common, or actions performed together. These might be communication, creating some common artifact, a common purpose such as study, worship, business, sports, etc. Nationality can be modeled as membership in an E74 Group (cf. HumanML markup). Married couples and other concepts of family are regarded as particular examples of E74 Group.
subclass of: Actor

Persistent Item
type: Class
notation: E77
comment: This class comprises items that have a persistent identity, sometimes known as “endurants” in philosophy. They can be repeatedly recognized within the duration of their existence by identity criteria rather than by continuity or observation. Persistent Items can be either physical entities, such as people, animals or things, or conceptual entities such as ideas, concepts, products of the imagination or common names. The criteria that determine the identity of an item are often difficult to establish -; the decision depends largely on the judgement of the observer. For example, a building is regarded as no longer existing if it is dismantled and the materials reused in a different configuration. On the other hand, human beings go through radical and profound changes during their life-span, affecting both material composition and form, yet preserve their identity by other criteria. Similarly, inanimate objects may be subject to exchange of parts and matter. The class E77 Persistent Item does not take any position about the nature of the applicable identity criteria and if actual knowledge about identity of an instance of this class exists. There may be cases, where the identity of an E77 Persistent Item is not decidable by a certain state of knowledge.The main classes of objects that fall outside the scope the E77 Persistent Item class are temporal objects such as periods, events and acts, and descriptive properties.
subclass of: CRM Entity

Symbolic Object
type: Class
notation: E90
comment: This class comprises identifiable symbols and any aggregation of symbols, such as characters, identifiers, traffic signs, emblems, texts, data sets, images, musical scores, multimedia objects, computer program code or mathematical formulae that have an objectively recognizable structure and that are documented as single units. It includes sets of signs of any nature, which may serve to designate something, or to communicate some propositional content. An instance of E90 Symbolic Object does not depend on a specific physical carrier, which can include human memory, and it can exist on one or more carriers simultaneously. An instance of E90 Symbolic Object may or may not have a specific meaning, for example an arbitrary character string. In some cases, the content of an instance of E90 Symbolic Object may completely be represented by a serialized digital content model, such as a sequence of ASCII-encoded characters, an XML or HTML document, or a TIFF image. The property P3 has note allows for the description of this content model. In order to disambiguate which symbolic level is the carrier of the meaning, the property P3.1 has type can be used to specify the encoding (e.g. "bit", "Latin character", RGB pixel).
subclass of: Conceptual Object
subclass of: Legal Object

Spacetime Volume
type: Class
notation: E92
comment: This class comprises 4 dimensional point sets (volumes) in physical spacetime regardless its true geometric form. They may derive their identity from being the extent of a material phenomenon or from being the interpretation of an expression defining an extent in spacetime. Intersections of instances of E92 Spacetime Volume, Place and Timespan are also regarded as instances of E92 Spacetime Volume. An instance of E92 Spacetime Volume is either contiguous or composed of a finite number of contiguous subsets. Its boundaries may be fuzzy due to the properties of the phenomena it derives from or due to the limited precision up to which defining expression can be identified with a real extent in spacetime. The duration of existence of an instance of a spacetime volume is trivially its projection on time.

comment: This property is a container for all informal descriptions about an object that have not been expressed in terms of CRM constructs. In particular it captures the characterisation of the item itself, its internal structures, appearance etc. Like property P2 has type (is type of), this property is a consequence of the restricted focus of the CRM. The aim is not to capture, in a structured form, everything that can be said about an item; indeed, the CRM formalism is not regarded as sufficient to express everything that can be said. Good practice requires use of distinct note fields for different aspects of a characterisation. The P3.1 has type property of P3 has note allows differentiation of specific notes, e.g. “construction”, “decoration” etc. An item may have many notes, but a note is attached to a specific item.

If a modification is applied to a non-man-made object, it is regarded as an E22 Man-Made Object from that time onwards.
domain:
  ressource: Physical Man-Made Thing
sub property of: was present at

was measured by
type: Property
range:
  ressource: Measurement
comment: This property is the inverse of the forward property described in the scope note that follows. This property associates an instance of E16 Measurement with the instance of E1 CRM Entity to which it applied. An instance of E1 CRM Entity may be measured more than once. Material and immaterial things and processes may be measured, e.g. the number of words in a text, or the duration of an event.

type: Property
range:
  ressource: Measurement
comment: This property is the inverse of the forward property described in the scope note that follows. This property records the dimension that was observed in an E16 Measurement Event.E54 Dimension can be any quantifiable aspect of E70 Thing. Weight, image colour depth and monetary value are dimensions in this sense. One measurement activity may determine more than one dimension of one object.Dimensions may be determined either by direct observation or using recorded evidence. In the latter case the measured Thing does not need to be present or extant.Even though knowledge of the value of a dimension requires measurement, the dimension may be an object of discourse prior to, or even without, any measurement being made.

[NO_INVERSE_LABEL_FOUND]
type: Property
range:
  ressource: Time-Span
comment: This property is the inverse of the forward property described in the scope note that follows. This property describes the minimum period of time covered by an E52 Time-Span. Since Time-Spans may not have precisely known temporal extents, the CRM supports statements about the minimum and maximum temporal extents of Time-Spans. This property allows a Time-Span’s minimum temporal extent (i.e. its inner boundary) to be assigned an E61 Time Primitive value. Time Primitives are treated by the CRM as application or system specific date intervals, and are not further analysed.
domain:
  ressource: Time Primitive

[NO_INVERSE_LABEL_FOUND]
type: Property
range:
  ressource: Dimension
comment: This property is the inverse of the forward property described in the scope note that follows. This property allows an E54 Dimension to be approximated by an E60 Number primitive.
domain:
  ressource: Number

was created by
type: Property
range:
  ressource: Creation
comment: This property is the inverse of the forward property described in the scope note that follows. This property allows a conceptual E65 Creation to be linked to the E28 Conceptual Object created by it. It represents the act of conceiving the intellectual content of the E28 Conceptual Object. It does not represent the act of creating the first physical carrier of the E28 Conceptual Object. As an example, this is the composition of a poem, not its commitment to paper.
domain:
  ressource: Conceptual Object

forms part of
type: Property
range:
  ressource: Symbolic Object
comment: This property is the inverse of the forward property described in the scope note that follows. This property associates an instance of E90 Symbolic Object with a part of it that is by itself an instance of E90 Symbolic Object, such as fragments of texts or clippings from an image.
domain:
  ressource: Symbolic Object

was type of object used in
type: Property
range:
  ressource: Activity
comment: This property is the inverse of the forward property described in the scope note that follows. This property defines the kind of objects used in an E7 Activity, when the specific instance is either unknown or not of interest, such as use of "a hammer".
domain:
  ressource: Type

type: Property
range:
  ressource: Physical Thing
comment: This property is the inverse of the forward property described in the scope note that follows. This property identifies an E90 Symbolic Object carried by an instance of E18 Physical Thing.
domain:
  ressource: Symbolic Object

type: Property
range:
  ressource: Attribute Assignment
comment: This property is the inverse of the forward property described in the scope note that follows. This property indicates the item to which an attribute or relation is assigned.
