In this sense it is fairly unique among all W3C groups. So we thought it would be helpful and more efficient to leverage that established background in this particular instance.

Yes - what really matters is that people come together and
collaborate, rather than the specific kind of group we use. There is
currently a small but potentially useful difference between Community
Groups and Interest Groups which is relevant here; the SWIG charter
(http://www.w3.org/2006/07/swig-charter.html) allows the possibility
that we can use W3C's teleconference facilities:

"The Semantic Web Interest Group exists primarily as an online forum;
it does not typically conduct weekly phone conferences. The Interest
Group may also conduct virtual meetings using email, IRC, wiki and
teleconference facilities, although the large scale, International
nature of the group motivates a focus on low cost, asynchronous
mechanisms such as email. The Interest Group may on occasion meet or
sponsor "Birds-Of-a-Feather" sessions at conferences, W3C Technical
Plenaries or alongside other W3C meetings, at the discretion of the
Chair and W3C staff contact."

In the context of these two groups, it might be useful to have the
possibility of teleconferences. I don't know what might be possible in
the future for Community Groups (and btw I consider these groups a
*huge* step forward for W3C) but for now, they are mail/wiki-based.

cheers,

Dan

Put another way: structured data on web sites is definitely now mainstream.

It defines a family of vocabularies that search engines "understand"; although these vocabularies are still evolving, they reflect the areas that search engines consider as most important for average Web pages. Independent of the vocabularies, schema.org also defines the syntax that search engines understand, i.e., how the vocabularies should be embedded in an HTML page. At the moment the emphasis from schema.org is on the usage of microdata[2].

Accordingly, as a result of a variety of discussions, I am proposing two new SWIG Task Forces to discuss these and flesh out solutions.  Note that this is also related to a TAG request from June [5].  Assuming the proposals are approved, the two Task Forces will be:
>>>
>>> 1. Web Schemas Task Force[6], to be chaired by R.V. Guha (Google), concentrating on general vocabulary-related discussions. The Task Force's focus should be on collaboration around vocabularies, mappings between them, and around syntax-neutral vocabulary design and tooling. Issues like convergence of various vocabulary schemas, use cases, tools and techniques, documentation of mappings and equivalences between schemas, should all be in scope for this Task Force.
>>>
>>> 2. HTML Data Task Force[7], to be chaired by Jeni Tennison, should conduct a technical analysis on the relationship between RDFa and microdata and how data expressed in the different formats can be combined by consumers. This Task Force may propose modifications in the form of bug reports and change proposals on the microdata and/or RDFa specifications where they would help users to easily translate between the two syntaxes or use them together. The Task Force should also work on a general approach for the mapping of microdata to RDF, as well as the mapping of RDFa to microdata JSON.
