v3.0.0
Conversion updates based on specifications v3.0. See the Library of Congress’s BIBFRAME site for more details. Specifications are included in the distribution in the spec directory. Changes of note:
- Medium of Performance conversion from MARC fields 048 and 382 is now located in a new specification (ConvSpec-048,382). Properties and classes from the Performed Music Ontology have been added to the BIBFRAME ontology and are used in this new specification.
- The ConvSpec-048-Codes specification is now obsolete.
- Music identifiers in the MARC 383 field now use new classes (bf:SerialNumber, bf:OpusNumber, bf:ThematicIndexNumber) instead of literals.
- Music key information from the MARC 384 field now uses a new object property bf:keyMode/bf:KeyMode
- Identifier source data from MARC 024 $2 now includes a URI from the Standard Identifiers vocabulary.
