Publishing Fennica as Linked Data is a work in progress. Some parts of this document are marked TODO, to indicate that the modelling or implementation is not yet finished. For more detailed information about current issues, see the open issues on the bib-rdf-pipeline GitHub project that implements the conversion of data from MARC records and auxiliary sources into the published RDF.
...
The data set is currently available as:
- a SPARQL endpoint on on http://linkeddata-kk.lib.helsinkidata.nationallibrary.fi/fennicabib/sparqlwith the following named graphs:
- <http://data.nationallibrary.fi/bib/fennica> - Fennica
- bibliographic data
- <http://www.yso.fi/onto/yso/> - YSO concepts
- <http://www.yso.fi/onto/yso-paikat/> - YSO places
- downloadable data dumps at at http://linkeddata-kk.lib.helsinkidata.nationallibrary.fi/download/ in HDT and gzipped N-Triples formats
- TODO Linked Data access (HTML, RDF/XML, JSON-LD, Turtle, N-Triples) via URI dereferencing
- TODO Linked Data Fragments access
...
The URI patterns are in draft status and may still change. Some entities are currently represented only as blank nodes in the RDF graph, but may later be given URIs.TODO the URIs in this data set are not yet resolvable. We plan to use the urn.fi resolver to manage identifiers, but it has not yet been set up to resolve this namespace.

Overview
This diagram shows the main entity types and their relationships as a UML class diagram.
