Improvements for next release

[orviz]

• Keep work on the common evaluation of indicators: https://docs.google.com/spreadsheets/d/1H5-15yCrM065k-u0seanQZ47BQ-WUUFVwGJFUNHwcBE/edit?gid=1759105918#gid=1759105918
• Support for creativecommons canonical licenses
• Adapt controlled vocabularies in api/utils.py to Vocabulary class. Start with existing vocabularies such as ORCID and SPDX
• Create a base class (e.g. EvaluatorBase) with all commonalities between plugins (api/evaluator.py)
  - Mandatory methods should raise NotImplementedError
  - Common evaluation of FAIR indicators should be coded there
• rda_i1_02m test in evaluatorBase is very OAI-PMH dependant. Change

[ferag]

I can't find anything to check creative commons canonical licenses automatically... Web scrapping or just add /legalcode could be a solution
