The OASIS eXtensible Access Control Markup Language (XACML) TC  members have recently approved a Committee Specification Draft (CSD) and submitted this specification for 30-day public review:
Request / Response Interface based on JSON and HTTP for XACML 3.0 Version 1.0
Committee Specification Draft 01 / Public Review Draft 01
25 July 2013
This profile aims at defining a JSON format for the XACML request and response. It also defines the transport between client (PEP) and service (PDP).
XACML is expected to address fine grained control of authorized activities, the effect of characteristics of the access requestor, the protocol over which the request is made, authorization based on classes of activities, and content introspection (i.e. authorization based on both the requestor and potentially attribute values within the target where the values of the attributes may not be known to the policy writer). XACML is also expected to suggest a policy authorization model to guide implementers of the authorization mechanism.
Public Review Period:
The public review starts 22 August 2013 at 00:00 GMT and ends 21 September 2013 at 23:59 GMT.
This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
