Collaborative Annotation Workflow Management

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

Open-source data curation for LLM fine-tuning and RLHF.

Unique: Implements workspace-scoped RBAC with record-level locking and response provenance tracking, enabling audit trails that link each annotation to a specific user and timestamp, critical for RLHF quality assurance

vs others: Provides finer-grained access control than Prodigy (which lacks workspace isolation) and simpler deployment than Doccano (no separate authentication service required for basic setups)
