The Linked Library Data project (LKD) adapts the BIBFRAME data model maintained by the Library of Congress to the needs of bibliographic description in Finnish libraries. The model supports the updated RDA description rules and the Metadata Thesaurus used in Finnish description work. This year the model is developed in phases according to the project roadmap.

The now released 0.6.0 test version includes properties of administrative metadata (bffi:AdminMetadata), classes and features related to classifications, and some other properties. To handle the title source we added a class and property. For conversions, we added a property to store the original MARC field information.

The data model can be viewed at
