There was a problem hiding this comment. Do I read correctly that the refined metadata of the last There was a problem hiding this comment. I'm not sure I'm following that one since There was a problem hiding this comment. If I understand the code correctly this will parse the a11y metadata that are refining each @chocolatkey Do you have an OPF example that this is supposed to parse? There was a problem hiding this comment. This is the example that we were using: https://github.com/standardebooks/nathaniel-hawthorne_the-house-of-the-seven-gables/blob/master/src/epub/content.opf#L19 There was a problem hiding this comment. Ha I see, in that case my initial question stands. We can have several conformances with different IDs and their own refinements. <meta id="conformance-statement" property="dcterms:conformsTo">EPUB Accessibility 1.1 - WCAG 2.2 Level AA</meta>There was a problem hiding this comment. Then it's probably a limitation of our model because the I'm hesitant to shake things up though, because it seems quite unlikely that you'd get certified multiple times (in most countries, there won't be a certification process at all). |
