Purely Virtual Object(e.g., email)
Virtual Counterparts (VCs)
Network Representation of Artifact – Data + Code + Execution (Autonomous Agents)
– Represents & Extends Artifacts
VCs are: – Autonomous– Coupled to
Artifact– Mobile

Basic Event Infrastructure– Event „RFID nnn appears or disappears“ – Collisions make objects become invisible for a
short time– Requires some corrections of the sensor
information
HUC2k Workshop
Issues
Ontology?– Do we need Hierarchies? Object Fusion?
Objects or Data (XML)?– Simplicity or Expressiveness?
Code Mobility– Aren’t all Networks Interconnected?
What’s in an Infrastructure?– Basic Services?
