Motivation

• drawbacks of current standardization initiatives
• lack of flexibility and extendibility
• fix standards are hard to maintain
• no possibility for suppliers to differentiate
  their offer
• lack of expressiveness
• description languages (e.g. XML) can not express
  all information, necessary for interoperability
• lack of semantic information (e.g.
  relationships), process information,
  constraints,...

4
Methodology

• modeling library of standardized building blocks
  as vocabulary for describing electronic tourism
  markets in a flexible and extendible manner
• conceptual, abstract modeling of tourism markets
• modeling based on the Unified Modeling Language
  (UML)
• sufficiently expressive modeling
• consideration of semantic aspects
• interoperability on different communication
  levels (e.g. XML or distributed objects)

Advantages

• rich, expressive modeling of the tourism domain
• focus on semantic aspects
• availability of the complete modeling information
  (esp. semantic aspects)
• flexibility and extendibility
• interoperability on different communication
  levels
• use of standard technologies (UML/XMI/XML/IDL)

Conclusion

• summarization
• methodology for harmonizing electronic tourism
  markets in a flexible and extendible way
• abstract, conceptual modeling based on the
  Unified Modeling Language (UML)
• next steps
• committing the methodology
• elaborating the reference model (UML model, XML
  tags)

• platform for elaborating the reference model
• executing a series of workshops and an
  accompanying email discussion
• first RMSIG workshop
• Friday, 1400 1600
• commit methodology and process for elaborating
  the reference model
