VOID vs DCAT targeting? #67

Closed VladimirAlexiev closed 3 months ago

VladimirAlexiev commented 6 months ago

I understand that RML wants to reuse existing vocabularies for targeting:

An external vocabulary such as DCAT, VoID, SD is allowed here. If a target cannot be accessed with existing vocabulary, a custom vocabulary can be used

The spec gives many examples of targeting void:Dataset.dataDump vs dcat:Dataset.distribution.accessURL, the first one at https://kg-construct.github.io/rml-io/spec/docs/#target-examples.

But what is the value of this? These examples do the same thing (target a file): so why confuse users (and indirectly ask developers to do more work) by giving both examples?

Showing that the specifications are not limited by a specific vocabulary. All these examples are not a MUST in the specification, you can use any specification you want for access.

so why confuse users (and indirectly ask developers to do more work) by giving both examples?

For the sake of clarity we should indeed just drop VOID. DCAT coverages more.
