Subject: OGC Announces Public Review for GeoXACML and OpenGIS Image Geopositioning Service (IGS) Draft Specifications
Members of this TC and other interested parties are encouraged to review and comment on the GeoXACML Draft Specification. Hal ------------------------------------------------------------------------ --- OGC Announces Public Review for GeoXACML and OpenGIS Image Geopositioning Service (IGS) Draft Specifications The Open Geospatial Consortium announced a call for public comment on two draft OpenGIS Implementation Specifications: GeoXACML and OpenGIS Image Geopositioning Service (IGS). The draft Geospatial Extensible Access Control Markup Language (GeoXACML) Implementation Specification defines a geo-specific extension to the Extensible Access Control Markup Language (XACML) OASIS Standard. The OGC GeoXACML draft clarifies that 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. The second OGC draft released for public comment is the OpenGIS Image Geopositioning Service (IGS) Draft Implementation Specification. This document defines an Image Geopositioning Service (IGS) interface to services that perform triangulation. Accompanying the IGS 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. OGC also recently published KML 2.1 Reference -- An OGC Best Practice. KML is a file format used to display geographic data in an Earth browser, such as Google Earth, Google Maps, and Google Maps for Mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard. http://xml.coverpages.org/ni2007-05-21-a.html
