Places Application Profile
Purpose
To document how various facets of LINCS data are modelled, along with reference authorities for the populating vocabularies. This will provide a basis for instruction for how to model data in a LINCS-compatible manner, as well as aid in navigation and discovery.
“Places” describes patterns that are unique or specific to representing information about places as both geographic and social concepts.
This document introduces the concepts as used by LINCS, and are not complete definitions of the CIDOC CRM ontology class or property concepts. Consult CIDOC CRM v. 7.1.1 documentation for full class descriptions and property descriptions.

Place Names
For more on identifiers, see the Identifiers section of the Basic Patterns Application Profile.
For how names are made of up parts (such as a full name having a first and last name), see the Identifiers section of the Basic Patterns Application Profile.
Different types of names are differentiated by the P2_has_type → E55_Type pattern associated with them (for more on this, see the Types section of the Basic Patterns Application Profile). For example:
Preferred name:

Pattern/Structure Values | Definition | This pattern declares that a place is identified by a name. |
Abstraction |
| |
Content Values | Type of Value | Uniform Resource Identifier (URI); literal value (text) |
Expected Value | URI from project dataset, existing linked data authority, or minted by LINCS; literal value from project dataset | |
Format/Requirements for the Value | URI (preferably dereferenceable); rdfs:literal | |
Case Examples | Typical Example & Abstraction | The Map of Early Modern London Gazetteer states that St. Saviour (Southwark) is named “St. Saviour (Southwark)” which is in English.
|
Edge Case Example & Abstraction | N/A | |
Resource Links | N/A | |
Discussion Elements Pertaining to This Pattern | Use at least one (1) E55_Type on each linguistic identifier specifying what it is. | |
Projects Following This Pattern | AdArchive, MoEML Gazetteer |

Content Values | Type of Value | Uniform Resource Identifier (URI) |
Expected Value | URI from project dataset, existing linked data authority, or minted by LINCS | |
Format/Requirements for the Value | URI (preferably dereferenceable) | |
Case Examples | Typical Example & Abstraction | The Map of Early Modern London Gazetteer states that St. Saviour (Southwark) is a type of eml:Church.

Geographies and Coordinates
Pattern/Structure Values | Definition | This pattern declares that a place is identified by a geographic reference. |
Abstraction |
| |
Content Values | Type of Value | literal value (text) |
Expected Value | literal value from project dataset | |
Format/Requirements for the Value | rdfs:literal | |
Case Examples | Typical Example & Abstraction | The AdArchive dataset states that there is a place located at the coordinates “-122.505020, 37.774750.”
