various errors with metadata.ttl

[laurianvm]

some comments based on reviewing https://data.emobon.embrc.eu/metadata.ttl

• if the team member doesn't have an orcID, it shouldn't be a person

<https://orcid.org>
   a foaf:Person ;
   foaf:name "EMBRC" ;
   foaf:mbox <mailto:[email protected]> ;
   .

• there is no '@base', making the urls of the 'schema:CreativeWorks' incorrect

@base <https://data.emobon.embrc.eu/> . 

• use of relative urls should not start with / (governance-data is OK)
• main project object identifier should not be a github.io uri but instead use fragment identifiers relative to base
  <https://emo-bon.github.io/emo-bon/emo-bon.github.io> rdf:type foaf:Project ; -->
