Add PICA-XML-Exchange format used in Folio?

nichtich commented 3 years ago

The CBS2Folio conversion uses a non-standard XML format for wrapping PICA records. In particular the XML has

no XML namespace
addditional fields status, hrid (these are the only parts not fully convertible to/from other PICA serializations)
datafields wrapped in new element metadata
datafields of item records grouped by epn in new element item
additional attribute fulltag (seems to be derived from tag and occurrence, so can be generated automatically)

If this format is rather a fluid ad-hoc tool, it may make more sense to put conversion from and to this format into the cbs2folio-transformations repository. Otherwise support in PICA::Data makes sense because it facilitates direct conversion between all other PICA serialization forms, syntax highlighting and querying.

See als conversion script from PICA to import format. There is some special treatment of x-occurrences as well.
