I am sorry! dc:maintainer doesn't exist. dc:publisher is not a perfect fit but might suffice.

I know this isn't germaine to DCAT, but was dc:maintainer a proposed/draft term at some point?

Regarding, the distinction between the dataset and its entry in the catalog: If the dataset is published by the publisher X and was created on 2013-01-08, then these are properties of the dataset itself and can be expressed as:

:dataset dc:publisher :publisherX; dc:created "2013-01-08"

If this dataset was added to the catalog on 2013-01-10 by you (:me) and you want to capture these information, then DCAT provides the CatalogRecord class

:cr foaf:primaryTopic :dataset; dc:created "2013-01-10"; dc:publisher :me .

This means that :me is responsible for the dataset record in the catalog and should be contacted about it while :publisherX is responsible for the dataset itself and should be contacted for issues related to the data.

Hope that helps.

Fadi
