Two entries have been added to the list of "reserved" prefixes, ie, those that may be included into the official vocabulary prefixes. These are odrl and as.

While these have no effect on current implementations and usage of RDFa and JSON-LD, be advised that, in the coming 1-2 months, three new prefixes may be added to the list:

oa: Web Annotation vocabulary
as: Activity (Streams) vocabulary
dqv: Data Quality Vocabulary

The first two are part of planned Recommendations; the third one is defined through an (already published) W3C Note. These changes may require a minor update on existing RDFa implementations.

Cheers

Ivan
