Annotations: Digital Post-Its(tm) as an Information Model?
Arnon S. Rosenthal, Scott Renner · Cooperative Information Systems · 1999
Questions the panel may address include: 1. Can we create a unified annotation service that applies across all the example media? What are the requirements for each medium, and what is common among them? What infrastructure and standards activities are required? Are they likely? 2. Do we need YADM (yet another data model)? Would XML be a panacea, a help, or a distraction? Should W3C's RDF be used?3. How would users want to discover, query, and view annotations? What are the requirements for performance, integrity, security,...?4. What data administration problems will be created by annotations? What happens when the annotated data changes? What happens when the annotated schema changes? What happens when new products are derived from annotated data?5. What database administration problems will be created? How can we get decent performance, with low administration overhead?6. Are annotations a suitable vehicle for collaboration (e.g., collaborative authoring)? Which problems might be solved? Which problems remain?
