In the process I've been thinking about the different ways Works are defined in FRBR and BIBFRAME. (Schema.org with the bibliographic extensions can be used to express Works the same way as BIBFRAME) My current opinion on this is that the BIBFRAME model, where bf:Work corresponds to the combination of FRBR Work and Expression, generally makes things simpler for conversion - you don't have to worry so much about whether something is merely a FRBR Expression of the same FRBR Work, or a separate (FRBR) Work. It also simplifies the data model since there are fewer entities in the chain. However, some things end up being duplicated or awkward. For example, subject description and classification is generally something that should be applied at the FRBR Work level (though there are exceptions in the actual records, for example I've seen "translated literature" as a 650 subject for a translated book). So if you have records both of the original work and its translation, the subject and classification information may have to be pooled from both and replicated one way or both ways between the two bf:Work entities. Of course this is nowhere as bad as with the original MARC records, where all subject description fields are duplicated across all the records of a single Work. -Osma [1] https://github.com/NatLibFi/bib-rdf-pipeline [2] http://tinyurl.com/linked-silos -- Osma Suominen D.Sc.
