• no additional agenda items suggested or added

PASS Access Control Conceptual Model (SOA) Update - Diana

• discussion on how obligation will fit into the PASS AC Model
• how obligations are dealt with in terms of SLS, and how to put obligations into the AC model at a higher (conceptual) level
• SOA meeting on Monday, discussion w/Don; placement of SOA diagram
  • pointed to process documents that SOA follows when completed functional model documents
  • based on the template (SOP/development practice) the diagrams of the FM will come after the FM model requirements

• • Kathleen would like to know why SLS is more in the weeds than obligations
  • ACS is a conceptual model, whereas SLS is more specific

there are some drawings in the SLS that have been adapted for that standards, with a little modification we can use those diagrams to update the SOA AC. Items will be convered conceptually

• in terms of behavioral modeling,
• Per Kathleen, there are items already in HL7 on obligations and care should be taken to align with those items.

• as an interoperability spec, we need to be able to relay that information

what the contract needs to say between the parties (what is being consumed)
what labels would be put on the document, including handling instructions which convey some policy.

when the obligations are a type of polcy that can be conved w security lables, but can also be enforced by custodian Discussion

ACS Model -

• revised version of functional model and corresponding requirements statements (v3) to Diana,Kathleen for distribution to group/for comment
  • biggest changes is consolidation/streamlined the authorization manager and started to promote to green level
  • consolidated to be cleaner (and to what Muhammad has recommend)

otherwise generally the same

Capabilities listing

• within the functional model diagram, reworked into a requirements statement
• in most cases, its background, or clarification. a subrequirement
  • recommend items should read as shall
  • additional recommendations noted
• note that guidance is heavily 'copy and paste'

what is the timeline for folks to provide comments?

• not specified yet
• items will be posted on GForge and link sent to Security WG

Joint Vocabulary Alignment

• preliminary guide for creating dicitionary vocabulary
• basic process outlined in the guide, in using the process group has come up with definitions in the viewpoint in EHR which will allow Security, Provenance and ___ and where they fit
• two definitions were processed (not quickly) at the last meeting; several distinctions were relayed at the last meeting making the process not quick, not repeatable. Having a process is better than where we were but the fine-grained distinctions may not relay to other languages.
• the notion of the extended definitions i.e. W3C mold, there is a core, one-sentence/well-crafted definition (following the rules), the extended definition contains much more detail, and in general where the definition is trying to get to. A broader description
• definite progress made, but there is concern on how long it will be before the definitions will be completed
• rules were determined from several places including Wiktionary (dictionary version of Wikipedia)

Example shown

PSAF Update - Kathleen sketching out policy information models previsoulsy working on the HCS in Harmonization:
