ISSUE-22: Backwards compatibility issue with case-sensitive prefixes in RDFa 1.0

Case-sensitive prefixes

Backwards compatibility issue with case-sensitive prefixes in RDFa 1.0

State:

CLOSED

Product:

RDFa 1.1 Core

Raised by:

Manu Sporny

Opened on:

2010-05-04

Description:

Section 7.5 item 4 indicates that prefixes, whether from @prefix or @xmlns, MUST be converted to lower case. However, XML namespace prefixes are case-sensitive. Test 0123 checks to ensure that this case sensitivity is retained in namespace mappings. I presume that this test is obsoleted by RDFa 1.1, and it's okay to break these dependencies (which were discouraged anyway).

This creates a backwards-compatibility issue with RDFa 1.0, where prefixes are case sensitive.

The RDFa Working Group must provide a resolution asserting that it is okay to break backwards compatibility with RDFa 1.0 in this manner.
