Add support for OpenAIRE

[jli2025]

This PR adds support for openaire metadata. It only supports import (openaire -> mcf).

It can use used for metadata record from the new openaire api: OpenAIRE Graph API

An example openaire metadata record: https://api.openaire.eu/graph/v2/researchProducts?pid=10.3390/proceedings2019030057

Thanx @jli2025 i’ll have a look asap

Hi @pvgenuchten I just added a commit to fix the identifier issue (when there is no pids) as we discussed.

Code looks really nice @jli2025, some small comments:

• I noticed a tag: test at root level of the generated yml, not sure how it was generated?
• Is it possible to add a /metadata/datestamp element on the record (maybe with date today, if the imported source does not have it), datestamp seems a required element on mcf

[pvgenuchten]

added minor fixes

@jli2025 Can you extend the plugin to make metadata_ = md.get('results')[0] optional
we can not assume the header/results wrapper is always available (although if it is available, good to unwrap the individual results) -> resolved

[pvgenuchten]

operational now, added a import test

Great work! Some additional comments/change requests.

actually, maybe we are too friendly here... we should also have a clear case indicating: "This json is not in OpenAire format", else it would parse any json and return an almost empty mcf... in case schema:autodetect is used

actually, the openaire is totally not considered yet when using autodetect, an update is needed elsewhere?
--> this is actually a problem of the schema-org plugin, the schema-org plugin returns empty document when not matching, and then does not continue to next schema to try

rebased to main... resolved conflicts... anything pending?
