Call for Participation in Community Group

The Community Group has been launched:

The Community Group provides a forum for discussing all changes, additions and extensions to In addition to providing a public setting for the day to day operation of the project, it serves as the mechanism for reviewing extensions and as a liaison point for all parties developing independent extensions to the core.

In order to join the group, you will need a W3C account.

This is a community initiative. This group was originally proposed on 2015-03-31 by Dan Brickley. The following people supported its creation: Dan Brickley, Richard Cyganiak, Vicki Holland, Ramanathan Guha, Bart van Leeuwen, Niklas Lindström, Markus Lanthaler. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team

    We wish that this group contributes a boost to project.


  • Wondering when the next update will be out? Just learning the ropes now with schema and using JSON on my sites.


  • Why is there no ‘StructuredData’ or ‘Microformat’ item?

    It seems strange, to me, that you cannot express in terms of

    The site has rdfs markup instead of markup.

    Also, the robots.txt is lacking.



  • I write reviews of short science fiction, and I’ve been using structured data because Google encourages it. I’ve noticed that there are a few gaps in the schema that make this harder than it should be.

    For example, there’s a difference between a work (like a story) and the way(s) that work is offered. (Magazine, anthology, collection, web page, etc.) “isPartOf” works, but that’s odd for “web page.”

    Anthologies are a problem because they have editors, not authors. Google, at least, doesn’t believe in a book without authors. It also doesn’t believe an editor can be an organization.

    Other issues arise when you want to talk about series and about single books bound in multiple volumes.

    Is there a separate working group thinking about issues like this?


  • Thanks for all the schema.. i appreciate your efforts..

    Hi folks. I have an interesting situation and possible solution I’d like to discuss with you. I’m marking-up a range of addresses for an “ApartmentComplex”. My solution (and Google’s Structured Data Testing Tool doesn’t seem to mind) is to do this:

    div property="address" typeof="PostalAddress">
    span property="description">21-45 Carriage Way
    meta property="streetAddress" content="21 Carriage Way">
    meta property="streetAddress" content="22 Carriage Way">
    meta property="streetAddress" content="23 Carriage Way">
    span property="addressLocality">Hurricane,
    abbr property="addressRegion" title="West Virginia">WV
    span property="postalCode">25526



    • I’d suggest repeating the whole ‘address’ block for each address, if you want to treat them as distinct addresses.


  • Hi there,

    Is there a plan to add new Schema for lottery numbers?
    We want to show our lottery winning numbers in google. What is the best way to get that into Google if there is no schema available for it?

    Thanks you


  • I am aware of no current interest in representing lottery numbers. Perhaps would be interested in recording them?

    Hi, i’m very confused how to get a sitemap with, can someone help me to do this?

    Best Regard.

    “ is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet” ( ). Everyone knows what “structured data” is? I don’t know, for example. What is “structured data”? Why no definition, no links/references?
