I understand legislative requirements, but not other technical details
Right, so you get that most legislation requires adherence to some version of WCAG at level AA in most situations. But what does this mean, and how do standards like PDF/UA, metadata schema and mark up languages help support achieving WCAG AA?
If you'd like to understand the detail, you can take a look at our Accessibility Standards section, that summarises and explains digital content standards (like WCAG), but also digital document standards (like PDF/UA or accessible EPUB, which are based on WCAG but with additional, file type specific features), and how to describe accessibility in metadata formats and select a specialised mark up language like MathML or MusicML.
And if you get a bit overwhelmed, you might like to zoom out and look at our collection of other resources, including:
Guidance documents and knowledge bases
Checklists to structure auditing and remediation
Models/frameworks to structure planning work
