for evidence that supports claims, do we need pointers within a URI?

Created by: monkeypants

Related to #42 (closed), when providing evidence to support a specific claim in a DPP (e.g. a conformity claim, facility location claim, etc) we can reference the evidence by a URI.

It's possible that the same evidence URI could support multiple claims. E.g. a document or audit may relate to multiple claims. . Perhaps we need a way to explicitly reference a location within the URI. For example, "Section 5.8" of the document at the given {URI}.

Maybe it's possible to use different URIs for specific parts of the same document. for example:

• fragment https://example.com/path/to/document#section-5-8
• query https://example.com/path/to/document?section=5.8
• path https://example.com/path/to/document/5.8

However, that won't be possible in all cases. For example

• https://example.com/path/to/document.pdf <-- "read Section 5.8"

Suggest maybe evidence needs another (optional) attribute that's an internal reference within the URI. Possibly multiples (human readable instruction, machine readable instruction).

in VCDM evidence model, it says "The precise content of each evidence scheme is determined by the specific evidence type definition." Does that mean we could specify an evidence type with this attribute, within VCDM?
