This document contains the approach developed collaboratively by the participants of the AR Browser Interoperability Engineering group (organized by the AR Standards Community) to achieve basic interoperability with geospatial AR experiences published in proprietary platforms and that can be opened and presented in the userʼs AR browser of choice (provided that the AR Browser publishing environment supports the architecture proposed). The purpose of the document is to describe the approach that has been implemented by providers of three AR browsers and which will be the basis of the first AR Browser interoperability experiment.
