CoAKTinG Concepts from Edinburgh Austin Tate, AIAI, 21-Mar-2002 First Ideas… Strong issues, activities/processes, state, event, agents, options, argumentation, rationale, presence, reports and messages model shared across CoAKTinG participants. Using Issue-based argumentation, Questions-Options- Criteria. Using ontology for synthesised artifacts such as plans and the products of collaboration. Using BuddySpace and I-Space ideas for agent awareness, relationships, capabilities and authorities. Generation of events based on real time feeds from the multiple media and modalities used in a collaboration. Use of UTC for time stamps (

I-N-C-A* Activity Ontology Issues Nodes (Activities) Constraints Include Node Constraints (sub-activities) Other Node Constraints Ordering/Temporal Constraints Variable/Object Constraints World-State Constraints Resource Constraints Other Constraints Annotations * Issues – Nodes – Constraints – Annotations is a model of a synthesised artifact made up of a set of constraints for issues – nodes – critical and auxiliary constraints. The separation of constraints Into critical and auxiliary classes is related to the I-X systems integration architecture.

Events, Reports and Messages Events and Reports related to activity –Begin of activity –End of activity - “Completion Report” Success Fail –“Progress Reports” Events and Reports related to change of world state –Special case of (dynamically alterable) values of attributes or objects altering. –“Process Products” How does this relate to FIPA events, messages and reports?

Time Stamps (UTC) Coordinated Universal Time Based on ISO Use XML Complete date plus hours, minutes, seconds and a decimal fraction of a second, with a Time Zone YYYY-MM-DDThh:mm:ss.sTZD Example: T19:20: :00 Times are expressed in UTC (Coordinated Universal Time) Special UTC designator ("Z") for “Zulu Time” (+00.00)
