Need some clarification on a previous issue

[GeorgeKerscher]

On #471 @wareid
made several comments.

Could we please get clarification?

First:
• For the EPUB metadata, this also requires additional logic to parse and split the value provided in dcterms:conformsTo which while not difficult, requires additional processing that seems unnecessary.
Please elaborate on what is not necessary.
Second:
Mentions of metadata properties in the ONIX and EPUB metadata docs are not made in the main document, which adds to the confusion.
We have a note that not all of the Additional Information is catalogued in the guidelines. Listing all of them would make the guidelines much longer and many of these are not frequently used.
What do you suggest?

For the EPUB metadata, this also requires additional logic to parse and split the value provided in dcterms:conformsTo which while not difficult, requires additional processing that seems unnecessary.

Looking at the original issue, I believe this is related to why the strings are being parsed rather than matched. It sounds like kobo would reject a string that isn't a full conformance statement, but this processing could match invalid conformance statements and even statements that don't have anything to do with accessibility or that use WCAG-like terms for an internal standard (e.g., there's no reason "Level A" couldn't be part of a conformance statement that has nothing to do with accessibility). The techniques assume there's only an accessibility conformance statement and that it's a valid one.

It might be safer to pattern match off the full conformance string/url since the epub and wcag versions, and the wcag levels, are always in predictable spots.

This is also an issue in the onix techniques. The algorithm assumes all the information about epub and wcag conformance has been set, but if only the level is set, for example, you could get weird statements like:

Conformance
This publication meets accepted accessibility standards
Detailed conformance information
This publication claims to meet Level AA

We aren't verifying that the information is complete before using it. The pending changes to the epub algorithm will prevent this from happening for package metadata.
