These sound like the same requirements for X3D:
http://www.web3d.org/x3d/specifications/x3d/
"X3D is a scalable and open software standard for defining and
communicating real-time, interactive 3D content for visual effects and
behavioral modeling. It can be used across hardware devices and in a
broad range of applications including CAD, visual simulation, medical
visualization, GIS, entertainment, educational, and multimedia
presentations."

I've been granted a guest role by the AR Consortium to contribute to
the open ARML process. Here is my first post to their, so far,

I wish creation of an ARML would be easy by simply adopting a KML
framework. I'm afraid this approach is strictly limited, and needs a
broader perspective. KML is a reasonable starting place for
discussion, but there are many dimensions of the ARML design
requirement that go well beyond the KML framework. Here are some
first principles I suggest we resolve in setting the specifications
for a Universal ARML:
* A Universal ARML will support both fundamental kinds of AR
requiring semantic frameworks be harmonized: 1. Image Triggered and
2. Location Based.
* A universal ARML will support many image trigger types, and many
coordinate systems.
* A Universal ARML is a description of what happens on the focal
plane of the view, including user interface conventions, and
rendering rules.
* A Universal ARML is a description of the properties of a specific
object or place, including data type, decoding and rendering
requirements and resources
* A Universal ARML will support local media types produced by many
applications domains including 2D Web, 3D web, web maps, GIS, CAD,
3D game and virtual worlds
* A Universal ARML will support local rendering rules and coordinate
systems for specific places and objects e.g. html, CAD objects and
spaces, video, rendered graphics game objects, etc.
* a Universal ARML will be a harmonized and interoperable semantic
framework with adjacent semantic domains within overlapping
computing and media domains, e.g. web, CAD, mapping, games, virtual
worlds, etc.
* a Universal ARML will support secure transactions and data exchange
* a Universal ARML will support sensors and sensor networks
* etc.
We are planning an AR Devcamp here in the San Francisco Bay Area,
now perhaps in November to explore these issues. In the meantime I
will post some follow up thoughts here on how we can organize to
support these principles.
I think it's important to realize that AR is not really a discrete
medium, it is the intersection of many media, So an ARML process,
needs to be inclusive, rather than exclusive. So, this private forum
is a good place to starting the process, ultimately a broad and deep
interaction with outside communities will be required to fullfill
the Augmented Reality vision.

H'mmm.... Since no-one here is directly engaged with these people,
I'm wondering how to channel experienced contributions to this
process... I've tried, but have been rebuffed. Was told that data
interchange is too "researchy" for the " AR industry" And here they
are running off, missing some pretty important issues.
Talking to ourselves about this is somewhat silly. Somehow the key
players need to be engaged here. Mobilzy - the proponents of this
inititive are already shovelling in 2d KML into their service,
oblivious of some of the issues we've thrashed to death here re,
CRSs, epsg pointers etc....

" Since mid 2009 companies started to develop augmented reality
(AR) applications for the latest generation of smart phones
(iPhone, Android, ...). Many of those applications overlay the
phone's cam view with interesting location aware data. Such
information can be points of interest from travel or tourist
services or real time data for instance from Twitter.
There is already a standard available to describe geo data. KML is
an open standard officially named the OpenGIS KML Encoding Standard
(OGC KML). It is maintained by the Open Geospatial Consortium, Inc.
(OGC). The complete specification for OGC KML can be found at http://www.opengeospatial.org/standards/kml/
.
Many companies and organizations have their geo data already
available in KML. Therefore it makes perfect sense to base the AR
data on KML and enrich it with custom extensions.
The basic idea behind this specification is that data that is
prepared using this specification can be viewed on augmented
reality browsers like Wikitude but also in Google Earth. Augmented
reality browsers can include an open URL dialog where the user can
enter an URL pointing to a valid ARML document. For instance such a
document can contain all affiliates of a company. People can easily
bookmark those URLs.
Augmented reality (AR) specific data is defined in an own KML
extension namespace.
Examples
Very Simple ARML Document
The simplest ARML documents are just plain KML. Any ARML compliant
browser must support these documents. Only the elements <kml>,
<Document>, <Placemark>, <name>, <description>, <Point>,
<coordinates> are required.
