Alexandre Bertails, Apple

Previously I was employed by the W3C where I worked on structured data.  Now I work at Apple in the department responsible for the web pages that describe our products and where to buy them, and Apple is increasingly deploying structured data in public-facing web pages, notably schema.org and Open Graph Protocol data. I have realized that the lack of offline tooling for automated testing, and the existence of different technologies with different syntaxes/vocabularies (mainly schema.org, Open Graph Protocol, and Twitter Cards) makes it difficult to deploy correct markup. Nor is it clear which parts of which structured data techniques are deployed by technologies such as search engines, or how consistent the adoption is.

In the context of W3C and standardization, I am especially interested in discussing the following subjects:

* a clear process for schema.org development, including possibly:
* how to effectively make contributions
* how to track implementations e.g. other W3C specifications there are Implementation Reports
* large chunks of Schema.org, OGP, and Twitter Cards have overlaps with each other or even internal overlaps: is there interest in unifying the three approaches, and being clearer about what is preferred and what is deprecated?
* helping the community understand the degree and consistency of support, e.g. by the creation of a site like caniuse.com for Structured Data
