Linked Open Data (RDF)
Sandrart.net is a project that handles structured data and uses relations (triples) between records. But nevertheless, due to the long history of the project (the application for funding was finished in early 2006), it was never planned to publish Linked Open Data or follow any Semantic Web strategy.
On the other hand, towards the end of the project it became obvious that it was both feasible and desirable to publish at least some of our data as Linked Open Data: people, places, works of art, bibliography items and the relations between them. Unfortunately, there is no easy way to map the relation types used by us internally to predicates in RDF—for some types of relations we could add a mapping, but most are not (yet?) supported. The same is true for the object properties. We hope, though, that even this incomplete data provided may be of some use.
Accessing our RDF data
There are several ways to access the RDF data:
- The permanent URL (PURL) of each database object (person, place, work of art, bibliography item) is at the same time the object’s URI. The response of requests to the PURL will, depending on the result of content negotiation, be a 303 redirect to either the RDF representation or the HTML representation.
- In each object’s HTML page, you will find a <link rel="alternate" type="application/rdf+xml" … /> tag which can be used to retrieve the RDF data.
- In the data returned by our REST API, you will find an identical tag.
- For convience, we additionally offer a GZip-compressed RDF dump at http://ta.sandrart.net/data/lod.rdf.gz.
- Information on our data set on the Data Hub
Examples
- RDF data for Hans von Aachen
- RDF data for the “Fruchtbringende Gesellschaft”
- RDF data for the townhall of Frankfurt
- RDF data for Trajan’s Column in Rom
- RDF data for Agricola’s “De re metallica”
