The [DBpedia Archivo Databus agent](https://databus.dbpedia.org/ontologies) generates only basic, static documentation for the archived snapshots of the ontologies. More, augmented and dynamic information for this ontology is rendered on and retrievable via [DBpedia Archivo Frontend](http://archivo.dbpedia.org/info?o=https://w3id.org/fog).

## Ontology Metadata

DBpedia Archivo extracts metadata from the ontology for well known properties (e.g. dct:description). This subsection shows the content of every property individually using a separate heading.

### dct:description

The File Ontology for Geometry formats (FOG) describes meaningful relations towards geometry snippets in RDF literals, geometry files on relative or absolute URLs and ontology-based geometry descriptions. The defined properties in this ontology are related towards each other and additional metadata is provided, such as file extension and related specifications/sources (incl. entries in dbpedia and Wikidata). 

The initial version of the ontology (v0.0.1) was documented in:

Bonduel, M., Wagner, A., Pauwels, P., Vergauwen, M., & Klein, R. (2019). Including Widespread Geometry Formats in Semantic Graphs Using RDF Literals. In Proceedings of the European Conference on Computing in Construction (EC3 2019). Chania, Greece.
