Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond.  it's in effect, a standardized way to structure data for consistency, SEO optimization, and interoperability.

What's this got to do with Drupal?

Well we're going to talk about Schema.org, content schemas (yes they're a thing), and new tools for your toolbox to create content entities that are compliant with Schema.org schemas, generate standards-compliant markup for SEO optimization and provide API data consistent with Schema.org schemas in JSON-LD format, among other things.  We'll demo Schema Blueprints, a new module package in development written by Jake Rockowitz, maintainer of the Webform package for Drupal.
