Standards Working Groups


1. ARML 2.0 Standards Working Group

ARML (Augmented Reality Markup Language) 1.0 is a descriptive, XML based data format, specifically targeted for mobile Augmented Reality (AR) applications. ARML focuses on mapping georeferenced Points of Interest (POIs) and their metadata, as well as mapping data for the POI content providers publishing the POIs to the AR application. ARML was defined in late 2009 by the creators of the Wikitude World Browser to enable developers to create content for Augmented Reality Browsers.

GeoServices REST SWG

This SWG is focused on processing the OGC GeoServices REST 1.0 candidate standard.

This OGC GeoServices REST Candidate Standard Version 1.0 standard is derived from the “Esri GeoServices REST Specification Version 1.0” which was developed to provide interoperability between ArcGIS Server and the broader information technology community. The candidate standard is designed to be implemented without the use of Esri products. The OGC version differs from the Esri version in that it is presented in a vendor neutral fashion appropriate for an OGC standard. For example the names of the types have been changed. The specification currently provides a JSON encoding, but does not limit alternate JSON representations (such as GeoJSON ).

PubSub SWG

The SWG shall review existing material, e.g. in form of OGC Engineering Reports and Standards (both OGC and external), to produce a version 1.0 implementation standard that clearly defines how to enable publish/subscribe functionality for OGC Web Services in a common way. If applicable, this standard may be a component of the OWS Common suite of standards. The items that need to be addressed by the SWG include:
1.      Write a core document that clearly defines the requirements for enabling publish/subscribe functionality.

GeoSynchronization 1.0 SWG

GeoSynchronization Service
Agile spatial data infrastructures based on OGC standards allow content provider organizations to deploy increasingly efficient networks capable of responding to dynamic requirements for using geospatial or location referenced content. In this context, content provider organizations are being more and more called upon to deliver current, timely and verified data over the World Wide Web.

Simple Features SWG

1.    ISO Simple Features
A Standard working group is being formed to work on the ISO version of the Simple Features specification. The intent is to create a fully harmonized standard so that the OGC and ISO standards and the SQL/MM Part 3 spatial versions are harmonized at the end of the work of the  SWG. A summary SWG description is given here and expanded below:


ISO 19125: Simple Features


Update the ISO 19125 (OGC) Simple Features standard to


The goal for the OGC GeoSPARQL standard is to support representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data.

The preliminary work on a draft of the candidate standard has been completed. As soon as possible, the SWG hopes to approve a 30 day Request for Comment for the candidate standard to the OGC Technical Committee and to the public. The resulting comments will guide the GeoSPARQL SWG in the finalization of the implementation standrrd, hopefully to be ready for a final standardization vote by OGC before the end of 2011.


1.    CF-NetCDF 1.0 Standards Working Group
NetCDF (network Common Data Form) is a data model for array-oriented scientific data, a freely distributed collection of access libraries implementing support for that data model, and a machine-independent format. Together, the interfaces, libraries, and format support the creation, access, and sharing of scientific data.
