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 ltI-N-CAgt 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/N
  OTE-datetime)

Issues Nodes Constraints
Annotations ltI-N-CAgt 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?

11
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-DDThhmmss.sTZD
• Example 1997-07-16T192030.450100
• Times are expressed in UTC (Coordinated Universal
  Time)
• Special UTC designator ("Z") for Zulu Time
  (00.00)
