Connecting LINCS and Wikidata

Wikidata serves as a major clearing-house of linked data Uniform Resource Identifiers (URIs), so there are advantages to connecting LINCS URIs to Wikidata.

LINCS-Minted URIs and Wikidata​

You may find that an entity exists in Wikidata or you have added it to Wikidata, but it already has a LINCS-minted URI (i.e., the URI starts with http://id.lincsproject.ca/). In this case, there are two ways to connect them.

  1. In your LINCS dataset, you can add an owl:sameAs relationship from the LINCS entity to the Wikidata entity.
  2. In Wikidata, you can add a connection to the LINCS entity using the “LINCS ID” property http://www.wikidata.org/entity/P14185. The value for that property in Wikidata will only be the 11-character identifier found at the end of the LINCS URI. For example, the entity “University of Saskatchewan Alumni Association” has a LINCS URI http://id.lincsproject.ca/Wl68dGIT0oZ. In Wikidata, you should use Wl68dGIT0oZ as the value of P14185. The full URI will be constructed automatically, resulting in a link from Wikidata to LINCS.

If possible, the link should be made on both sides so that both LINCS users and Wikidata users can discover the connection.

External URIs used in LINCS Data​

Whenever possible, LINCS tries to find existing URIs to represent entities. In those cases, LINCS directly reuses the existing URI instead of minting a new URI. For example, LINCS uses a VIAF URI http://viaf.org/viaf/317285133 as the primary identifier for A. Bowerley (see https://rs.lincsproject.ca/resource/?uri=http://viaf.org/viaf/317285133).

To connect a Wikidata entity to a LINCS entity page that uses an external URI, you may use the “described at URL” property https://www.wikidata.org/wiki/Property:P973 with the entire URL of the LINCS entity page as the value, that is, https://rs.lincsproject.ca/resource/?uri=http://viaf.org/viaf/317285133.

Again in your LINCS dataset, you can add external URIs including Wikidata using the owl:sameAs property.
