Collaboration II
Notification and linkage service can be based on object registration mechanism and allows important collaborative capabilities
one associates with each group activity a “magic ID” (barcode)
every digital object associated with this activity registers itself when it comes on line with some registry (registry can be distributed). A given object may have multiple barcodes attached to it
- This is Jini model for registration but can be implement for pure Web (using JavaScript) or CORBA
Either users or Portals (PSE’s) register interest in certain barcodes
The (Portal) event service notifies registered observers when a digital object of interest becomes available
