Example FAIRmat parsers
Most parsers that we will write in FAIRmat, will probably just be "simple" converts that transform already structured data (e.g. JSON) into archive/metainfo data. As working examples, the eels, mpes, aptfim parsers, which simply convert json/dict data, should be rewritten to use the new metainfo instead of the nomadcore/python_common backend-based libraries.
Make sure to work on the nomad-fair-metainfo
branches of the parsers. Do not use the older parser base-classes and use nomad.parsing.MatchingParser as a baseclass. No nomadcore imports should remain. This will need a new parser base class, i.e. MetainfoParser that returns a metainfo section instead of a backend. We later need to adapt the processing to handle both backend-based and metainfo-based parsers.
