Set up models as dataclasses with xsdata

[afuetterer]

• Set up models with xsdata:

python -m pip install xsdata[cli,lxml]

xsdata https://www.openarchives.org/OAI/2.0/OAI-PMH.xsd --package=models  --include-header --max-line-length=120 --docstring-style=Google --union-type  --postponed-annotations --structure-style=single-package

• replace "Type" with ""

sed -i 's/Type//g' src/oaipmh_scythe/models/oai_pmh.py 

Figure this out:

• Record is always part of oaipmh schema
• metadata element depends on metadata format, that is used in request (oai_dc, datacite, etc.)
• if params["metadata format"] == oai_dc, from models import oai_dc
• how to parse metadata with model from other xsd schema, that is loaded at runtime?
• has to happen in OAIItemIterator.__iter__() on the level of the individual record

  oaipmh-scythe/src/oaipmh_scythe/iterator.py

  Line 194 in 3f471da

  mapped = self.mapper(item)

• if item.metadata do something

xsdata https://www.openarchives.org/OAI/2.0/OAI-PMH.xsd --package=models.oai_pmh --include-header --max-line-length=120 --docstring-style=Google --union-type --postponed-annotations --structure-style=single-package --slots --kw-only --subscriptable-types
