Working Group Status
IETF Working Group chartered beginning of 2002.
Initial Charter: Design of a framework that enables authorization and invocation of networked services at the application level, including
– A protocol for invocation of remote call-out services,
– Standard formats for description of invocation rules (postponed),
– Trust and thread model for application services inside the network.

OPES Callout Protocol (OCP)
OPES Rules Language
Initial focus was on HTTP-based applications, but the design aims to support other application protocols as well.

Summary Of Proposed Re-Charter
Consensus on new charter has been established via mailing list discussions.
– New charter proposal is stable and has been submitted to IESG.
– Propose re-charter was sent out to IETF Announce list.
Proposed work items are focused and narrow, and follow the established OPES framework.
– Continue to address IAB considerations for OPES (RFC 3238).
Two new work items:
– OCP profile(s) that will support OPES services operating on SMTP.
• Includes a document on scenarios and use cases.
• First profile will address the needs of at least the MTA.
– OPES rules language
• Includes discussion of relationship to “sieve”.
• Possibly based on previous work on “P”.
