The National Library of Sweden has taken a policy decision to base the format in Libris XL on BIBFRAME 2.0, supplemented with elements from other models.
We call this our ”Release 0”, which is meant to indicate two things:
Firstly, even though the model is not yet complete, it is sufficiently stable to build services on;
Secondly, we are aware of the lack of details and will continue to fill in the gaps after this release, thereby more releases are to be expected before Libris XL is fully operational.
For more background on how the model was developed, a presentation from last years ELAG describes the difficulties of change, what boundaries are reasonable and why the choice of vocabulary is critically important.
For more about the philosophy behind our work, see Niklas Lindström’s presentation from ELAG 2015.
