Dear list readers,
I just started studying the Data Catalogue Vocabulary (DCAT, 
http://www.w3.org/TR/vocab-dcat/), but I have some doubts. If I 
understood, DCAT can be used to model catalogues of datasets, and not 
datasets by itself.
Thus the dcat:Dataset instances represent datasets or entries in 
catalogues? The CatalogRecord class can be used to provide additional 
meta-information about an entry in a catalogue, am I right? Does a 
catalog record some relationships with distributions of the dataset the 
entry refers to?

Now, let us suppose that I have the same dataset reported in two 
different catalogues, which reports different (not necessarily 
contraddictory) information. Should I have a single dataset instance and 
two catalog records, or two dataset instances as well?

Any help is welcome,
thanks in advance,
Cristiano Longo
