Introduction
The fc:photo semantic annotation refers to the photographs which are shared by the Photo Archives and depict the works of art & built works that are part of the Artresearch project and is the domain used for the semantic modeling described below.
Relationships

Model Section Description
A combination of cidoc crm ontology, fundamental categories and relationships was used in order to achieve the most efficient way for the retrieval of the semantic data. The fields used to describe a photo can be functionally grouped according to higher level units in order to allow for an easier approach to the navigation of the data by information category. The information categories identified have been enumerated in the following table.
| # | Name | Description |
|---|---|---|
| 1 | Photograph | This information category gathers together descriptos used for assigning names,types to a photograph, both at present and historically |
| 2 | Photographer | This information category presents information related to artists and persons related to the documented photograph |
| 3 | Physical Properties | This information category presents information related to physical properties of the documented photograph |
| 4 | Provenance | This information category presents information related to the provenance of the documented photograph. |
| 5 | Subjects | This information category presents information related to the subject of the documented photograph. |
| 6 | Dating | This information category presents dates related to the documented photograph. |
| 7 | Notes | This information category presents notes related to the documented photograph. |
