ISSUE-64: RFC 3066 or RFC 5646 for language tags?

RFC 3066 or RFC 5646 for language tags?

State:
CLOSED
Product:
RDF General
Raised by:
Richard Cyganiak
Opened on:
2011-05-30
Description:
RDF Concepts defines language tags with reference to RFC 3066.

RFC 3066 is obsoleted by RFC 5646.

Should language-tagged literals in RDF 1.1 still be defined in terms of the (simple) RFC 3066, or in terms of the (much more hairy) RFC 5646?

RESOLVED to close ISSUE-64 by replacing the current text:

[[
Plain literals have a lexical form and optionally a language tag as defined by [RFC3066], normalized to lowercase.
]]

with:

[[
Plain literals have a lexical form and optionally a language tag as defined by [RFC5646]. The language tag, if present, MUST be well-formed according to section 2.2.9 of [RFC5646], and MUST be normalized to lowercase.

NOTE: Earlier versions of RDF permitted tags that adhered to the generic tag/subtag syntax of language tags, but were not well-formed according to [RFC5646]. Such language tags do not conform to RDF 1.1.
]]
