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.
