Dear Mike, HTML5,
The Media Fragments WG has issued a Last Call WD a couple of month ago
and would welcome comments from the HTML WG on its entire specification
"Media Fragments URI 1.0" located at
http://www.w3.org/TR/2010/WD-media-frags-20100408. If you plan to send
comments, please let us know and do send your comments to
<public-media-fragment at w3.org> with "LC Comment" in the subject.
Furthermore, following the coffee discussion Mike and I had 2 weeks ago
at TPAC, I point you to this bug entered in the HTML5 bug tracker:
http://www.w3.org/Bugs/Public/show_bug.cgi?id=10723 "support for media
fragment URIs in relevant HTML5 elements".
This bug describes the particular problem of rendering spatial media
fragment in a HTML browser. The Media Fragments WG has written this non
normative paragraph :
"For a spatial URI fragment, we foresee two distinct use cases:
highlighting the spatial region in-context and cropping to the region.
In the first case, the spatial region could be indicated by means of a
bounding box or the background (i.e., all the pixels that are not
contained within the region) could be blurred or darkened. In the second
case, the region alone would be presented as a cropped area. How a
document author specifies which use case is intended is outside the
scope of this specification, we suggest implementors of the
specification provide a means for this, for example through attributes
or stylesheet elements."
We will start discussing with the CSS WG how this styling could be done
but the Media Fragments WG also thinks that if a default behavior must
be specified, it should happen in the HTML5 specification.
