Aligning definitions of dcterms:hasPart and its subproperties #1465
Description
The current definitions are as follows:
| Property | Definition |
|---|---|
dcterms:hasPart |
An item that is listed in the catalog. |
dcat:dataset |
A collection of data that is listed in the catalog. |
dcat:service |
A site or end-point that is listed in the catalog. |
dcat:catalog |
A catalog that is listed in this catalog. |
The proposal is to revise them as follows:
| Property | Definition |
|---|---|
dcterms:hasPart |
A resource that is listed in the catalog. |
dcat:dataset |
A dataset that is listed in the catalog. |
dcat:service |
A service that is listed in the catalog. [definition proposed in #1431] |
dcat:catalog |
A catalog that is listed in the catalog. |
The rationale is that there is no need to describe the range of the property with an abridged definition of the relevant class, as we need just to point to it (as already done in the range of the property definition). Another issue is that this may lead to confusion - e.g., as highlighted in #1431 for the definition of dcat:service.
About the definition of dcterms:hasPart, "item" should be replaced by "resource", as the range of this property in DCAT, when used to link a catalog to one of the listed resources, is dcat:Resource (or a subclass thereof). Moreover, the use of "item" led to a misunderstanding reported in #1454 .
The proposal has been implemented via PR #1466
