GeoXACML Implementation Specification


The Policy Language introduced in this document defines a geo-specific extension to the XACML Policy Language, as defined by the OASIS standard “eXtensible Access Control Markup Language (XACML), Version 2.0” [1]. Due to the similarity of XACML version 2.0 to it’s predecessor versions (e.g. 1.0 or 1.1), the extension described in this document also represents a valid extension for earlier XACML versions. As being an extension to OASIS eXtensible Access Control Markup Language (XACML), GeoXACML provides support for spatial data types and spatial authorization decision functions. Those data types and functions can be used to define additional spatial constraints for XACML based policies.
