Because MRAID is based on ORMMA, this set of APIs and principles closely resembles the original ORMMA API. The ORMMA developers have since edited the ORMMA API to provide full integration of MRAID into ORMMA.
Each API method that exists in MRAID is documented as part of the ORMMA spec and behaves in identical fashion.
This allows publishers and ad servers who support ORMMA specifications going forward to stay compliant with MRAID 1.0 at the same time. ORMMA will continue to propose new methods to the IAB group for consideration in future MRAID versions with the goal of keeping ORMMA and MRAID on the path to total convergence.
With the IAB release of MRAID 1.0, the ORMMA group members, many of whom also collaborated on the writing and ratifying of MRAID version 1.0 should see this as a victory for open standards.
We thank the IAB for galvanizing our efforts over the past year and thank the MMA for their important endorsement of this project.
