TOP 1 Welcome

TOP 2 Introduction of Participants

  • 5min presentations of each group, slides optional

TOP 3 The OMM: current status and known issues

  • Syntax
    • Syntax details 1: content encoding (xpdl), blockID: tag or attribute, idType
    • Syntax details 2: tagnames and namespace
    • Block Meta data
  • Structure and organization
    • Table of contents, e.g., in the core block? Example: temperature data in block A, B, C
    • The binary origin: wanted and unwanted characteristics in the XML model - example Attribute Block
    • Standardized blocks: example "dedicated block for physical data" or "event list", with standardized or open contents
    • Storing events in the memory
      • Every event is a block or...
      • One block with a (standardized) list of events or...
      • One block with a (arbitrarily structured) list of events
  • Data links on the OMM: linking OMMs, linking external resources and memory representations, interaction with physical relationships between parts of an artifact
  • Using the memory
    • E.g.: Decision criteria which help to decide
      • what to store
      • how to store (see: various ways of storing events)

Top 4 OMM architectures

  • (candidate) Presentation: A classification scheme for OMM implementations

Top 5 Topics not or little addressed so far

  • Access
    • Logging
      • Is the access list part of the object memory?
    • Rights
      • How to handle read/write rights in a technology independent way?
  • List of requested, but unavailable data
  • Supporting binary conversion (keynote SemProM DFKI-IFS?)
  • Modeling active components (hardware) of an OMM (keynote SmartProducts TUD?)
  • Modeling active behavior
  • Modeling data distribution behavior (keynote SmartProducts TUD/SAP?)
  • Modeling behavior on changing ownership of an artifact
  • Modeling data needs of an OMM
  • Software components (e.g., access API)
