Subclass of:

• crm:E55 Type

Scope note:

This class comprises types of groupings of specific ceramic forms that can be used by appropriate experts to categorise individual objects, fragmented or not. The Shape declaration is based on the morphological characteristics (curvature, thickness, position and type of decoration) of an ideal object deduced either from many typical instances or reconstructed from knowledge of vessel parts when intact exemplars do not exist or are insufficient to ground the positing of a Shape.  Shape groupings are often hierarchical, for example grouping ‘one-handled cups’ and ‘large cups’ under cups, or cups and bowls under open vessels. Different shapes are more or less readily identified: In some cases simple wall fragments can be assigned the shape ‘dolium’ based on their thickness, in other cases rim or base fragments of a very specific shape can still belong to different shapes (e.g., a jug or jar, cup or bowl). The substance of an instance of Shape is a conceptual classification created for scientific analysis. 

An instance of Shape comes into being upon its declaration and continues to exist thereafter even if disproven or superseded, so long as it remains an object of discourse in scientific literature.
