Re: DCAT and catalog entries

Dear Richard, thank you very much for your reply, but something remain 
unclear to me.

The question is just whether you refer to that dataset by a single name (IRI) in both catalogues, or by two different names (where asserting owl:sameAs between them would be correct). There is nothing wrong with either approach, and which one to choose depends on various practical considerations.
I borrowed the term "instance" from Description Logic. My issue is about 
merging two catalogs with two different entries, one for each catalog, 
about the same dataset, where different means which reports different 
information. Let us consider for example two catalogues, say C1 and C2, 
and a dataset D with title "the title" and a landing page 
http://landingpage.org. Of course we have just one data set, but two 
different (in the real world we are describing) entries e1 and e2, one 
for each catalog.

Now, let us consider the case in which, may be for a typo, the title of 
D reported in C2 is wrong. Can I model this in DCAT? I'm not sure but 
examining the example in the documentation I suppose that CatalogRecord 
and hasCatalogRecord are not suitable for this purpose.

Thanks again,
CL
