ESON the EMF Simple Object Notation textual DSL syntax, an alternative to XMI (formerly known as EFactory)
This presentation will introduce you to https://github.com/vorburger/efactory.
EFactory is an Xtext syntax representing generic EObject models in a textual (DSL) syntax. It looks like JSON, but retains EMF's strong typing, and is in effect an alternative to XMI.
If all goes according to plan, EFactory will be renamed to ESON, and based on discussions with Ed Merks at EclipseCon Europe hopefully integrated into eclipse.org EMF (alongside Xcore, probably).
