mets: other language than german

[tboenig]

Hi @wrznr ,

here a problem with a other language than german. METS snippet: <mods:languageTerm authority="iso639-2b" type="code">lat</mods:languageTerm>

mm2tei --ocr "https://content.staatsbibliothek-berlin.de/dc/PPN647473836.mets.xml"

Actually, it is not a problem with other than German but rather a problem with lat. The Python package that mets-mods2tei uses for translating ISO 639-2 codes to "real" language names (which for some reason DTABf requires) does not work for Latin. Thanks for pointing out this issue! Fix will be provided.

Hi @wrznr,

An automatic and complete translation into another format is ideal. But this cannot always be guaranteed. See mets:Hdr. For this reason I would suggest that the program does everything possible and, in case of problems, gives me a log file documenting the difficulties of the conversion.
