1 Routing and Security theory David E. Ellis

2 Definitions The TSG defines the View of objects by message types. There is a hierarchy of Views which will be defined by set theory. View + is the wrapping of a View as a EDXL-DE content object. The View+ carries distribution information in EDXL-DE metadata and is acted on by the TSG components. View ++ is the wrapping of an View+ object with a TSG Message Envelope which carries Message Assurance, Stewardship Contracts, Flow Control, distribution tokens and hop limit metadata

3 Agent Current metadata in View View+, and View++ Role dynamically assumed by Operating Environment of TSG SPOR agent OrganizationContextSubjectObjectAction Define Organizational Configuration of Agent Activity

4 Define logic Define (org, s, o, α, c) if o is member of View (O) where C contains (specific metadata (c) ), then there is a finite set of (a) member actions of Activity (A) where internal configuration of A test true with context (c). When this test is true there are a finite set of (s) members of Role within Organization (O) which can perform Activity (A)

5 View 1 View 2 View 0 View 2 View 1 View 0 View 1 View 2 View 3 View 2 View 0 View 1 View 2 COI A COI C TSG A COI B All Arrows depict “member of” relationship CAP Msg EAS Msg WSI Msg EAS Msg HA Msg EAS Msg HA Msg SPOR 1SPOR 2

6 View 2 View 1 View 0 View 1 View 2 COI A COI B CAP Msg EAS Msg WSI Msg EAS Msg HA Msg MSG 1 MSG 2 MSG 3 MSG 4 MSG 5 MSG 6 MSG 7 MSG 8 MSG 9 STATE EAS Public

7 Delivery Policies COI A and COI B are counties in different states and have specific internal locations for distributing CAP alert & warning Msg. COI B is in a state where the State EOC is only authority to send out a EAS Msg. Each COI creates CAP message which activates unique EAS system. Keywords are used to determine routing policies which apply to the message.

8 Issues to be resolved Granularity of CAP Message typing for internal COI versus external distribution When can a CAP message use all possible typing for distribution purposes Where are these types inserted in the EDXL-DE messages. When does a distribution policy preclude the Member_of Keyword use When does use of CAP headline not clarify as an Alert & Warning message

9 Restricted Content Unrestricted Content County EOC CDC County Health Department State Health Dept DHS State EOC
