Access levels

• Public access
  Metadata, permitted exploration and published files are available directly.
• Conditional access
  Metadata remain visible while the user requests access and accepts the declared conditions.
• Strictly controlled access
  Viewing or delivery may be limited to a secure environment and requires explicit approval.

The final access vocabulary, migration of historical rules and approval workflow belong to the next implementation stage. Until then, no legacy label will be interpreted automatically as permission to publish.
