CoAKTinG Concepts from EdinburghAustin 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 <I-N-CA> 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 (http://www.w3.org/TR/NOTE-datetime)

Annotations

* Issues – Nodes – Constraints – Annotations<I-N-CA> is a model of a synthesised artifact made up of a set of constraints forissues – nodes – critical and auxiliary constraints. The separation of constraintsInto 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 8601. Use XML• http://www.w3.org/TR/NOTE-datetime• Complete date plus hours, minutes, seconds and a decimal

fraction of a second, with a Time Zone• YYYY-MM-DDThh:mm:ss.sTZD• Example: 1997-07-16T19:20:30.45+01:00• Times are expressed in UTC (Coordinated Universal

Time)• Special UTC designator ("Z") for “Zulu Time” (+00.00)
