All Primary datasets

incl. the changes discussed today, fake DOIs from Tibor's file, only missing 2 descriptions. Descriptions and other examples will follow tomorrow morning
OK, I see.  If the collection itself is not enough, then it is surely good to "tag" records as Research or Education.  (1) However, we should at least use different subfield `980 $b` to denote these apart.  (2) Shall we have one day `/collection/Research`?  If not, then `980` is not really the right place (even though INSPIRE uses it that way); we may want to consider using "tagging" field such as `650` or `653` or `695` perhaps?
