Milestone Working Package 3

WP3 investigates how extended contracts between fragments of hypermedia documents can be defined.

Basic goals for this milestone

• research on general possibilities to define semantic constraints for fragments and variation points
  • examining semantic web technologies (like ontologies), rule-based languages and pattern compare techniques
    • semantic constraints
    • support to declare dependencies between aspects
  • goal: extended contracts for fragments
  • selecting and integration of best-suited approaches for adaptive hypermedia documents into ISC
• application of the new concepts to the domain of adaptive hypermedia documents
  • extension of LWDCS (WP1) by possibility to resolve aspect conflicts
    • specifically for identified conflict types (WP2)
    • on the basis of general constructs (WP3-a)
  • how can authors specify the maximum extent of adaptability for documents?
  • description/specification of aspect interactions (as specified in WP2) and possible conflict solutions
  • development of a semi automatic technique to resolve conflicts
• integration of dynamic XML weaver in AMACONT pipeline
  • investigation of usefulness of XML weaver in AMACONT (expressability, speed)
  • context information from client may help to recognize conflicts

Secondary goals

• integration of the developed tools in AMACONTBuilder and AMACONT pipeline
• if Reuseware use cases are successful (WP1) to a greater extent, a combination of the new AMACONTBuilder with Reuseware (Air)? can be fruitful
• --> combine the results of student practical (should be finished around 02/09)

• investigation of the combination of AMACONT and the developed weaving techniques on authoring time (Punkt ist mir noch unklar)
  • static weaving investigates integration of Reuseware and AMACONTBuilder
• investigation of the pipeline integration before delivering to client
  • performance plays a big role
  • examination of changing weaving stages
  • separation of different concern types
• investigation of adaptation on client
  • partial outsourcing of application logic to client
  • investigation of additional available context information

Innovations achieved by this milestone

• method for specifying semantic restrictions and relations (like dependency) on fragments and composition operations
• identification of concepts for the description of conflicts and corresponding solution strategies for adaptation aspects in adaptive hypermedia documents
