The Open Geospatial Consortium (OGC®) seeks public comment on the candidate OGC Augmented Reality Markup Language (ARML) 2.0 Encoding Standard.

ARML 2.0 provides an interchange format for Augmented Reality applications to describe and interact with objects in an AR scene, with a focus on mobile, vision-based AR. The candidate standard describes the virtual objects that are placed into an AR scene, as well as the registration of the virtual objects in the real world, and allows interaction with and dynamic modification of the AR scene using ECMAScript bindings.

ARML 2.0 emerged from ARML 1.0, developed by the creators of the Wikitude World Browser, and was completely remodeled within the OGC ARML 2.0 Standards Working Group to fit existing AR use cases.

The OGC ARML 2.0 Standards Working Group has set a specific focus on a generic way to describe Trackers in an Augmented Reality environment, allowing users to define a multitude of Trackers, such as Marker-Trackers, Face-Trackers, Natural Feature Trackers and even non-vision-based Trackers, to allow a multitude of AR use cases to be implemented with ARML 2.0.

The OGC ARML 2.0 Encoding Standard Evaluation Package is free and can be downloaded from http://www.opengeospatial.org/standards/requests/94. The deadline for comments is 2 December 2012.

The OGC is an international consortium of more than 465 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available geospatial standards. OGC Standards support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. OGC Standards empower technology developers to make geospatial information and services accessible and useful with any application that needs to be geospatially enabled.
