Use of word "context" in the definition of dcat:catalog and related properties #1460

Closed riccardoAlbertoni closed 2 years ago

riccardoAlbertoni commented 2 years ago

As pointed out by Nobuyuki OGURA in a recent discussion, the use of the word "context" in the definition of dcat:catalog and related properties (dcat:dataset, etc.) is quite vague. (see https://www.w3.org/2022/02/22-dxwgdcat-minutes#r02)

For example, in dcat 2 rec, the property dcat:catalog is defined as

"A catalog whose contents are of interest in the context of this catalog"

the class dcat:Catalog is defined as

A curated collection of metadata about resources (e.g., datasets and data services in the context of a data catalog)

Is there a better way to express the same idea?

riccardoAlbertoni commented 2 years ago

I wonder if dropping the reference to context could be a solution. My hunch is that it would simplify the sentence maintaining the meaning in the definitions.

For example, the property dcat:catalog would become

"A catalog whose contents are of interest of this catalog"

the class dcat:Catalog would be defined as

A curated collection of metadata about resources (e.g., datasets and data services of a data catalog)

Yes, it seems that dropping "context" will improve understanding a lot. If you allow examples in Definition, I would like to suggest adding them as following:

A catalog whose contents are of interest of this catalog (e.g. parent standard, related standard, etc.)

dcat:catalog property is a sub property of dcterms:hasPart, the implication of which is that the linked (object) catalog metadata collection is included in the subject catalog. A more precise definition would be 'a catalog whose content is included in this catalog'. The motivation for inclusion ('of interest') is a note, but not part of the definition. +1 on @riccardoAlbertoni definition of dcat:Catalog suggested above

I've just realised that we are referring to the DCAT2 definition of dcat:catalog, which we have already revised in DCAT3 (see PR https://github.com/w3c/dxwg/pull/1370) to make it consistent with the definitions of dcat:dataset, etc. (https://github.com/w3c/dxwg/issues/1156):

A catalog that is listed in this catalog.

I suggest we close this issue.

riccardoAlbertoni commented 2 years ago

Sorry, I was implementing the resolution https://www.w3.org/2022/02/22-dxwgdcat-minutes#r02 , and I hadn't realized this was not an issue in DCAT 3. Let's close it.

Closing.
