Hi Eric,
Your question reminds me of https://www.dublincore.org/specifications/dublin-core/dcq-html/.
I'm not sure I agree with everything in it (specifically: using <meta> to specify RDF namespace prefixes used in other <meta> elements feels weird), but it did point to a more generally accepted HTML way of using URIs with types – the <link> element and `rel` attribute.
The IANA Link relations registry<https://www.iana.org/assignments/link-relations/link-relations.xhtml> contains relation names for `rel`, but you could use a URI as `rel` too. Signposting<https://signposting.org/> is based on typed links, for example.
Alternatively, you could include JSON-LD metadata in a <!cript> element, usually with Schema.org terms, for SEO and other purposes.
I'd be interested in what solution(s) you find useful.
Regards,
Ben

Subject: [CODE4LIB] how do I specify uris as metadata values in xhtml
How do I specify URIs as metadata values in XHTML?
I have the following well-formed and valid XHTML:
<?xml version="1.0" encoding="utf-8"?>

</html>
To make the value of terms.creator more useful, I'd like specify a URI instead of a literal. For example, instead of denoting "Eric Lease Morgan", I'd like to specify "https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.wikidata.org%2Fwiki%2FQ102275801&data=05%7C02%7Cb.a.companjen%40LIBRARY.LEIDENUNIV.NL%7Ccf708ce6ee174b34645508dc4ff54762%7Cca2a7f76dbd74ec091086b3d524fb7c8%7C0%7C0%7C638473162079660688%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=IHL79uuksNvq8E1tnQ2gWuf91wcuc1kbMbm%2FeHnaGUk%3D&reserved=0<https://www.wikidata.org/wiki/Q102275801>", but if I simply put the URI in the content attribute, then how will an RDF processor know the value is a URI?
