Durable Control. Portable Records.
OpenETR
A formal working surface for Digital Artifacts, Anchor Records, Evidence Events, and derived consequential state.
openetr core with four adapters:
web app, CLI for human use, CLI for agent use, and API for agent use.
Work With Records
Query Digital Controllable Record
Upload a Digital Artifact and verify the DCR evidence associated with its digest. The result enumerates candidate Anchor Records, Evidence Events, derived controller state, lifecycle state, and policy warnings.
No Control Desk Key session is active.
Most visitors can query DCR evidence without logging in. Use the Login page only if you need Commitment Profile management, Anchor publication, or relay-backed Control Desk recovery.
This FastAPI app lives outside the packaged openetr component so the
web layer and its dependencies can evolve independently while still reusing the same
shared query, publish, guard, and profile workflows.
The methodology for this shared-core approach is described in the multi-modality architecture note.
Interactive API docs are available at /docs.
