Today we started a community group (CG) at the W3C for “Web Media Text Tracks”: http://www.w3.org/community/texttracks/.
The group has been created to work on many aspects of video text tracks of which captioning and the WebVTT format are key parts.
The main reason behind creating this group is to create a forum at the W3C for working on WebVTT to allow all browsers to support this format and be involved in its development.
We’ve not gone the full way to creating a Working Group, although that was the initial intention. We had objections from W3C members for going down that path, so are using the CG path for now.
This is actually a good thing because CGs are open for anyone to join, while WGs are only open to W3C members. The key difference is that specs coming out of WGs can become RECs (“standards”), while CG’s specs cannot.
If we eventually see a need to move WebVTT to a REC, that move will be straight forward, since there is a clear path for work to transition from a CG to a WG.
