- For schema.org's proposals tracker, see Extension proposals (W3C database entry)
- Web Schemas was a W3C group used by the schema.org project to collaborate with the wider community.
- The group is not just for schema.org; however there is more traffic here about schema.org because it is the only schema.org mailing lists. Other projects/vocabularies are very welcome also!
- Since 2014 schema.org uses Github for active development (like many other W3C communities).
- Schema.org now has a dedicated W3C Community Group including a email@example.com mailing list
- This Wiki is left primarily for historical record...
The taskforce chairs are R.V.Guha (Google) and Dan Brickley (Google)
In scope include collaborations on mappings, tools, extensibility and cross-syntax interoperability. An HTML Data group is nearby (see also public-html-data-tf list); detailed discussion about Web data syntax belongs there.
See the charter for more details.
The group uses the firstname.lastname@example.org mailing list
- See email@example.com archives
- Issue Tracker (organized into "Feedback on X" products/categories, where Xs are Schemas we're discussing)
- To subscribe, send a message to firstname.lastname@example.org with Subject: subscribe (see lists.w3.org for more details). To unsubscribe, do the same but use 'unsubscribe' in the title.
- If you are new to the W3C community, you will need to go through the archive approval process before your posts show up in the archives.
- To edit this wiki, you'll need a W3C account; these are available to all
- To search just this WebSchemas wiki, the issue tracker and schema.org-related mailing lists, try a a custom search.
Groups who maintain Web Schemas are welcome to use this forum as a feedback channel, in additional to whatever independent mechanisms they also offer.
In particular, the Schema.org initiative has adopted this group as its primary public feedback forum. Others are invited to do likewise.
Any W3C-related questions, ask Dan Brickley (SWIG chair), c/o email@example.com
For background discussion on this group, Schema.org and W3C's SWIG, the Oct 2011 Semantic Link podcast may be of interest.
For schema.org there are discussions on various sites (unofficial; this group is the only place monitored by Schema.org team) :
Talks and slides:
Proposals from and for Schema.org
The main table for managing/tracking schema.org proposals is maintained here: Schema.org Proposals
A separate entry discussed Schema.org Process as it relates to this group.
Possible future discussions for Schema.org extensions (proposals welcomed; this list is free-form...):
- Points of Interest (POIs), collab with OGC group. See data model, latest spec draft.
- Journals / scholarly publishing
- Cultural heritage - libraries, museums, archives. See Linked Library W3C group, Europeana, DPLA, LOD-LAM etc.
- Bibliographic Schema Bib Extend
- Integration of constructs based on Good Relations, FOAF, Dublin Core, ...
- Linked Govt data
- Software / Apps
- Cars and Vehicles
- the relationships between all of these
Some discussions are in fact targeted at the underlying syntaxes used for exposing schema.org markup:
Tools and Statistics
- Metadata statistics from Yahoo! Search
- RDFa, Microdata and Microformat deployment statistics from WebDataCommons.org (August 2012)
- RDFa, Microdata and Microformat deployment statistics from WebDataCommons.org (November 2013)
- Sindice stats (announcement)
- General stats discussion incl. Bizer et al.'s CommonCrawl extraction (announcement); there is some debate about shortcomings of this analysis and the proper interpretation of these.
- Search Tools
- Authoring Tools
- Vocabulary QA
- Sandro Hawke made a list of 'overloaded' schema.org properties that expect sometimes a Thing, sometimes a Text value.
Mappings between various vocabularies of interest on the Web Schemas list. The following are mostly using schema.org as a hub, but others would be great to collect too.
- UMBEL schema.org mappings (data is in github)
- Dublin Core / Schema.org Allignment taskforce.
- schema.rdfs.org mapping page.
- A discussion note on schema.org and OData is available.
This group is about vocabulary (schemas) rather than specific markup syntax details. However since syntax specs are evolving in parallel, there are often discussions that need to mix syntax and vocabulary issues.
- from structured-data.org, some examples showing RDFa 1.1 lite versions of Schema.org's Microdata samples
Schema.org example sites - the following list give concrete examples of Schema.org sites (testable with Google richsnippets tool):
