Of your list we have discussed Datum,
One of our definitions for Data has the idea of a unit.
Data is a collection of datum.
Others in your list seem important (scale and granularity) but haven't been part of a RDA group's work yet.
They obviously have been discussed and are part of some models. There is an RDF vocabulary for scale for example.
Other terms are spatial and temporal and have relevant standards as noed by Jeffery in a later email:
For spatial coordinate systems metadata ISO191115 / EC INSPIRE standard is very good and widely used.
There are as well some ontological models for these but haven't been integrated into our current vocabulary.

Hi Peter,
Actually, I am unclear the scale of DFIG terms and what are the basic principles of selecting terms. So I try to add some terms I think they are very important to define, describe and use data. Hope it will useful to perfect DFIG terms.

Dear all,
i just grabbed all terms I could in DFIG documents and comments so far. I am sure that much is missing.
But it may give a first impression. Most of the terms are not well-defined and people are using different definitions.
Please, feel free to add terms and references.
best
Peter
