Mappings defined in DCAT-AP+Schema.org (3/3)

Part 1 | Part 2 | Part 3

Status of this document

This document presents a proposal for mapping the relevant terms from the DCAT Application Profile for European Data Portals (DCAT-AP) to the Schema.org vocabulary.

This document is a draft meant to report work in progress. As such, it can be updated any time and it must be considered as unstable.

Abstract

This documents illustrates the mappings defined in DCAT-AP+Schema.org.

The background and methodology for the design of DCAT-AP+Schema.org are illustrated in a separate document:

DCAT-AP+Schema.org: Background & methodology

A SPARQL implementation of the defined mappings is available in a dedicated folder (../sparql/).

GeoDCAT-AP 1.0	O	geometry	locn:geometry	schema:geo	Schema.org expects as value an instance of schema:GeoCoordinates (for points) or schema:GeoShape (for more complex geometries). LOCN allows any type of geometry, and any type of geometry encoding / representation—including those supported by Schema.org. As a consequence, the locn:geometry mapping might require further processing to encode the geometry according the encodings supported in Schema.org.
