Framework for collaborative annotation
• Different types of annotations will be covered ranging from simple free-text notes to specialized linguistic markups
• What is annotated: documents available via the internet.• Architecture: one DB&server - multiple clients (different
use cases)• Distinguishing feature: storing annotated copies of
documents
