Collaborative Document Annotation And Markup With Role Based Permissions

via “collaborative team annotation with role-based access control”

Open-source text annotation for NLP tasks.

Unique: Uses Django's permission framework with project-level role assignment, where roles are enforced at the serializer level in REST endpoints — each API call checks user.has_perm() before returning data, ensuring no leakage of unauthorized annotations

vs others: More lightweight than enterprise platforms like Labelbox (no custom role hierarchies) but more structured than Prodigy's single-user focus; better for teams needing basic RBAC without complex permission matrices
