I just got an email from the Oracle Technology Network:
"Explore OTN Semantic Web (Beta) – and Provide Feedback!
OTN Semantic Web, now in Beta release, is a proof-of-concept application that demonstrates the use of RDF (Resource Description Framework)-based "Semantic Web" technology as the basis for a user experience that relies on dynamic relational navigation as well as Ajaxian user interfaces."
They've given links to the demo and FAQ.
As a developer, I thought this FAQ point was interesting:
"Why do different collection pages have different user interfaces?
This Beta is intended to expose users to a range of Semantic Web functionality and Ajaxian UIs. For that reason you will see several different varieties of each, and we welcome your feedback about each of them."
I wonder if they're collecting data on mouse patterns and running path analyses to see which interfaces are more effective.
