Both... we're going for general video metadata markup. :)

Just to be clear, those names are "property names"... they are not the
official Microformat "class name" that we are going to use in hVideo. It
is too early to decide on a vocabulary yet... expect most of those names
to change (re-used from other Microformats if possible, created if there
is no other choice). We do, however, define what every one of those
property names mean on the video-info-examples page:

The Permalink URLs are for sites that explicitly state a Permalink URL
on the page. Believe it or not, only 58% of the examples had permalinks.
I was surprised as well, but it shows us why we collect examples.

All definitions of property names are listed on the video-info-examples


published - The Published Date specifies the date that a video file was
made available to the public. Examples include: The airing date of a
video podcast, the air date of a television show, or the release date of
a movie.

If the data is in the DOM somewhere, we included the property. If the
data doesn't reside in the DOM, then we did not include the property.

Got a list of examples that we could merge into the video-info-examples
page? That would be very helpful...

It is! Most users are publishing video via MySpace, Yahoo Video, Google
Video and YouTube... service websites. However, if you have another
subculture that we should examine, please give us some links so that we
may analyze those sites as well.

We need your examples, then! :)

Nope... in fact, what we're finding is that most of the video sites do
not sell content! Bummer, as we were hoping we'd find that they do... :)
but since we can't find many examples of this happening, it nullifies
the idea that this is a use-case for selling video or other content.

Thanks for the input Mary, always appreciated :). Do these statements
help clarify matters?
