I was not present during the discussion of the Media Annotation namespace, but the current name space http://www.w3.org/ns/ma-ont mentioned in the ontology dratf is coherent with the "Namespace URIs in Recommendation Track Documents" [1] Director approval is NOT REQUIRED when a namespace URI in a Technical Report has any of the following forms: * http://www.w3.org/ns/ssss * http://www.w3.org/YYYY/MM/ssss * http://www.w3.org/YYYY/ssss where: * ns is the literal string "ns" * YYYY and MM are decimal digits corresponding to the year and month of URI allocation * ssss is a short string not causing confusion, alarm, or embarrassment. For instance, the short string should not cause confusion when used in both http://www.w3.org/TR/ssss and http://www.w3.org/ns/ssss URIs. But use of syntax such as http://www.w3.org/YYYY/MM/ssss enables the W3C support staff to ensure very high level of persistence for namespace URIs, in terms of the non-reuse and the availability of any online materials (schemata etc).
