This project aims at enabling any JSON data that complies with the OCDS JSON Schema to be published as Linked Data.
The OCDS is a data model that aims at structuring and publishing contracting data (tenders, procurements, awards, transactions, etc.). It got international adoption and is one of the leading models in this domain.
Linked Data is a way of publishing data that relies on few principles:
- a resource is identified with an HTTP URI (not a plain string)
- dereferencing (HTTP GET) this URI returns data about the resource
- the description of the resource contains relations to other resources, also identified with URIs.
The result: a meshed network of resources than can easily be traversed by a machine.
RDF is the framework that powers Linked Data.
The first deliverable of this project is an ontology (~ schema) that translates the structure and semantics expressed in the OCDS JSON Schema into RDF.
- Turtle file with lots of comment in the header
- Visualization
- SPARQL endpoint
You can find the JSON-LD context files like this format context-xxx.json. We create one context file per concept at the ontology.
