The product of collaboration at W3C, the Annotea project now has a home page.
Annotations are external remarks attached to any Web document.
When the user gets the document he can load the annotations and see what his peer group thinks. The first client implementation of Annotea is W3C's Amaya browser and authoring tool. See a quick tutorial for annotations to get you started. This project is part of the W3C Semantic Web Activity Advanced Development work to develop and deploy RDF infrastructure. Winie version 1.0.8 is available for download.
