We are pleased to announce that MetaVidWiki  (link) is now in open beta. We look forward to you comments, suggestions, and bug reports on this new free platform for community audio video participation.

We have put together a new extended screen cast demoing MetaVidWiki features available here on metavid. (also available on google video, and xvid copy here (23 megs) ). Editing on MetaVidWiki site is now open to anyone that can pass a audio or visual captcha test…

So check out the demo video, try some searches, and then try improving the archive by syncing a transcript or improving some text content

Simultaneously we are releasing the software that powers metavid: MetaVidWiki extension (v.01). It has been packaged and released for other cool re-uses of the code base. The Mv_Embed package has been updated to version .7 and released as well.

Read on for Technical Feature overview:

MetaVidWiki extension (project page)

dependencies: MediaWiki, mod_annodex or oggz-chop, LAMP stack
recommend: the Semantic MediaWiki Extension.

• Adds namespaces for Streams, temporal stream metadata, and sequences.
• Adds interfaces for editing multiple sub-name-spaces of temporal metadata per Stream or layers. Enabling the separation of transcript languages, annotative layers or the defining of other layer types.
• Adds a media search engine based on page semantic properties and defined layer types.
• Extends Categories, Page Histories, and Semantic result sets with inline video playback.
• Adds an in-browser sequencer for editing and creating sequences from clip segments.
• Exports to video rss for categories & searches. Exports CMML for temporal metadata.

Specifically for the legislative archive:

• Auto-completes media searches with likely people, bills, issue groups or full text search.
• massive data scrape from open secrets, maplight, govtrack, and others to populate base data set.
• template based display of people, bills, & interest groups (separating data from display while remaining flexible with user contributed structured data)

Mv_Embed (full feature list)

• Is a stand alone javascript library used for video playback in MetaVidWiki
• Abstracts all ogg plugins to a near html5 spec, letting web developers target a single abstraction for multiple underlining plugin or native video support systems.
• Supports draft ROE (Rich Open multitrack media Encapsulation) spec for xml distribution of media.
• Supports playlists in xiph xspf , rss or inline format.
