To use or not to use recommended metadata in a W3C ontology ?

In reference to issue https://github.com/w3c/sdw/issues/537

The proposed integration methodology (see readme.md) includes the following
item:

- be conformant with the linked vocabulary best practices at
http://lov.okfn.org/Recommendations_Vocabulary_Design.pdf

These best practices encourage among other to use vocabularies vann and
voaf.

A first comment in issue 537 suggests we should not use these vocabularies.

(Krzysztof, if I may, for the record:

years and they are not

research project.

I guess I would like to have some more opinions from the group participants

If we give up on those, I would like to modify the document that describes
the integration methodology accordingly.

Kind regards,
