Drupal 8 comes with a shiny new Entity Field API (codename: EntityNG) based upon the underlying Typed Data API. However, we have too few developers that are into the details of the new APIs. So in this session we'll try to get a broader understanding of the APIs, followed by a discussion of what's left/next.

Outline:

Introduce the Typed Data API and the ideas behind it
See how EntityNG and Typed Data relates
Validation for Typed Data and entities (based upon symfony validator)
Current status of the conversion
Discuss problems and next steps
