Subclass of:

• crmsci:S20 Rigid Physical Feature
• crm:E25 Human-Made Feature

Scope note:

This class comprises instances of S20 Rigid Physical Feature that constitutes a surface produced through one or several instances of A1 Excavation Processing Unit. Instances are often documented through drawing and/or measured by technical means such as photography, tachymetry or laser scanning. Using a planar excavation methodology this is typically the surface of a planum or the surface of a profile. Using a stratigraphic excavation methodology, the instance of A10 Excavation Interface would have the intention to approximate an instance of A3 Stratigraphic Interface. The drawing and measurement of profiles is also common practice when a stratigraphic excavation methodology is used.

Examples:

the Excavation Interface Planum 6 of square I22 in Area F-I, documented in the field drawing “Planum 6 F-I i22”, created in Fall 1982 (Bietak, 1996)

the Excavation Interface Eastern profile of square I22 in Area F-I, documented in field drawing “Ostprofil F-I i22”, confining the excavation square I22 to the East (Hiebel, Aspöck and Kucera, 2017)

In First Order Logic:

• A10(x) ⇒ S20(x)
• A10(x) ⇒ E25(x)

Incoming properties:

• crmarc:A1 Excavation Processing Unit → crmarc:AP4 produced surface (was surface produced by) (0,1:0,n)
