May 15, 2007. Wayland, MA. The Open Geospatial Consortium, Inc. (OGC®) seeks public comment on two draft OpenGIS® Implementation Specifications:

1) The OpenGIS Geospatial eXtensible Access Control Markup Language (GeoXACML) Draft Implementation Specification (OGC Document 07-026) defines a geo-specific extension to the eXtensible Access Control Markup Language (XACML) OASIS standard. "Access control systems" enable management of access to information only until it is obtained by the user and stored locally, as opposed to "rights management systems" that remain in force regardless of where the content of the original resource is located or reproduced. This draft specification can be downloaded from

2) The OpenGIS Image Geopositioning Service (IGS) Draft Implementation Specification defines an Image Geopositioning Service (IGS) interface to services that perform triangulation. (NOTE: The name of this service has not yet been formally agreed upon.) Accompanying this draft specification is a separate OpenGIS Image Geopositioning Metadata Geography Markup Language (GML) Draft Application Schema, which is structured to provide consistency between the IGS and other OGC Web Services (OWS) specifications. This draft specification can be downloaded from

Suggested additions, changes, and comments on these draft specifications are welcome and encouraged.

The OGC® is an international industry consortium of more than 335 companies, government agencies, research organizations, and universities participating in a consensus process to develop publicly available interface specifications. OpenGIS® Specifications support interoperable solutions that "geo-enable" the Web, wireless and location-based services, and mainstream IT. The specifications empower technology developers to make complex spatial information and services accessible and useful with all kinds of applications. Visit the OGC website at
