Clarification on Use of @id, PURL Identifier, and Impact Statements

[nikosgalanis]

Hello,

I have a few questions and requests for clarification regarding some fields in an OpenVEX document, given the spec provided:

• What should be the @id field in the document’s metadata? Can it mention the location where the final document will reside?
  • In the package structure, is there a point of having an @id and a purl identifier, or can we opt to go with one of them? And if yes, is it valid to just have the purl identifier in the @id field?
  • Could we have impact_statement in every status? If not, how could we add notes that clarify the status to the user?

TIA!

Sorry for missing this @nikosgalanis

What should be the @id field in the document’s metadata? Can it mention the location where the final document will reside?

The IRI in the @id field is used to uniquely identify the document. Ideally it should be retrievable, especially if you plan to point to it from other documents but vex statements are self-sustaining so it can also be private.

In the package structure, is there a point of having an @ id and a purl identifier, or can we opt to go with one of them? And if yes, is it valid to just have the purl identifier in the @ id field?

Yes you can just have the purl in the @ id field and be done with it. Or in the identifiers. The point of id is to make the elements identifiable from other linked documents.

Could we have impact_statement in every status? If not, how could we add notes that clarify the status to the user?

That field is defined upstream from the VEX WG, we cannot alter it as it would break the general VEX definition. For affected we have an action_statement where you can convey messages.

For which status do you need it the most? Help me understand more and I can propose it to the wider VEX community.
