Raw data

Placename metadata from our web archive is publicly available as raw data. It is available as open linked data in the format of RDF Turtle.

Permanent identifier

Each placename (thing/resource) has a permanent identifier that is globally unique. It comes in the form of an Internationalized Resource Identifier (IRI). The permanent identifier makes it possible to link to our placenames from any system.

Example:

https://resource.fylkesarkivet.no/placename/df2d05e0-c3bc-e811-810c-001dd8b71c74#

Permanent identifier link redirect

Any request to a permanent placename identifier will redirect to our publicly available presentation page for the placename, unless the request ask for "Content-Type", "text/turtle", in the header.

“Content-Type: text/turtle” requests will redirect to the public available metadata we have about the placename. Example:

https://placename-raw-data.fylkesarkivet.no/placename/rdf-turtle/df2d05e0-c3bc-e811-810c-001dd8b71c74

Version code

Each identifier comes with a metadata version code. It changes when metadata about the thing have changed in our web archive.

Example:

<https://resource.fylkesarkivet.no/placename/df2d05e0-c3bc-e811-810c-001dd8b71c74#> <https://ontology.fylkesarkivet.no/placename#DataVersion> "AAAAAAATQww=".

Q: What placenames are listed in the graph?

A: Both placenames that have published metadata, and the ones that have not, is in the list.

Q: How are deleted placenames detected?

A: Deleted placenames will just disappear from the list.

Parse RDF Turtle format

In order to parse the RDF Turtle format, we recommend using dotNetRDF, a complete library for parsing, managing, querying and writing RDF. See their documentation on GitHub for examples on how to do this.
