3. 3 April 2009 SLE: SLE Services Pink Sheets reviewed Next steps: RID Disposition, Area resolution and publication. CSTSes: Framework: ASN.1 Reviewed Prototype: Coordination & Specification of a dummy service Concept: detail review Guidelines: detail review Introduction presentation will be run before the 3 books review in all Agencies. Monitoring Data Service: Content & structure reviewed. Monitoring will be limited to the specification of the service (No parameters) Monitored parameters will go in a “Data Dictionary” – Book colour Blue (TBC) Others: AOS-CLTU uplink: Status and new version presented by NASA. Final version pending the SLE RIDs disposition. In case IOAG would require an AOS-uplink service to be implemented, the WG recommends to base it the specifications and subsequent implementation on the Framework and Guidelines. Interagency routine file transfer guidelines: Initial brainstorming. CSTS WG REPORT A.SUMMARY TECHNICAL STATUS
