Since June 2013 a few of the Mobile AR Browser providers have been examining how they can provide greater value to their developer community and to end users by building very basic interoperability into their solutions. This initiative is described on this page of the AR Standards portal.

Last month the top engineers of Layar, Wikitude, Seac02 and metaio met in person in Amsterdam and made significant progress towards their goal of simple geospatial POI interoperability.

The results of that meeting are captured in a new paper published for comments today via a mailing list of the AR Standards Community for people who are publishing mobile AR browsers. Feedback is invited until the comment period ends on November 15.
