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?
