Artsdata Guidelines regarding Persistent Identifiers
As per the W3C’s RDF specifications for linked open data, each named entity (for example, an event, a place or a person), class and property loaded in the Artsdata triple store must be denoted by a persistent identifier, represented as a URI (see this article to learn more about persistent identifiers).
Supported and recommended persistent identifiers
Artsdata assigns its own persistent identifiers (URIs) to named entities that meet minimum requirements for ID minting. Registered users can use the “Minter” feature to link or mint a new Artsdata ID for entities that are already loaded to the knowledge graph. They can also use the “Mint using Wikidata” feature to load a Wikidata item and mint a new Artsdata ID.
Artsdata also relies on external URIs. Artsdata supports all persistent identifiers from open knowledge bases, including:
- Wikidata;
- ISNI;
- VIAF;
- Musicbrainz.
Artsdata also accepts local URIS minted by data providers (read more below).
In order to guide data providers and consumers in the adoption and implementation of persistent identifiers, here are recommended persistent identifiers according to the entity type.
| Type | Artsdata ID | Wikidata ID | ISNI | Local URI |
|---|---|---|---|---|
| schema:Person | Recommended | Recommended | Recommended | Optional |
| schema:Organization schema:PerformingGroup |
Recommended | Recommended | Optional | Optional |
| schema:Place | Recommended | Recommended | Not a valid type for this ID | Optional |
| schema:Event | Recommended | Optional | Not a valid type for this ID | Optional |

About the Artsdata Identifier
The Artsdata ID is a globally-unique persistent identifier for any concept or named entity in the Artsdata knowledge graph. It can be assigned to performing arts entity types for which there exists at present no good persistent identifier (for example, an event). Any entity that meets minimal requirements and that passes SHACL validation can be minted an ID.
Third parties are welcome to contribute to assigning Artsdata IDs. Registered users may:
- Use the “Minter” feature, in the Artsdata interface, to mint or link an ID to an entity loaded to the knowledge graph;
- Use the “Mint using Wikidata” feature, in the Artsdata interface, to load an entity from Wikidata and to mint or link an ID for it;
- Use the Minting API to assign IDs to entities that have not been loaded to Artsdata yet.
Specifications
- URI format:
http://kg.artsdata.ca/resource/$1 - Regex for the ID:
^K\d+-\d+$ - Sample URI:
http://kg.artsdata.ca/resource/K12-438 - Note : The URI format doesn’t use a secured “https” protocol, as is often the case for URIs with content negotiation.
