DAS Registry

The DAS Registry is part of the DAS specification.

The registry is a special component of DAS, fulfilling the following roles:

  1. Catalogues and describes the capabilities and coordinate systems of DAS servers.
  2. Allows discovery of available DAS services via both human and programmatic interfaces.
  3. Automatically validates registered DAS sources to ensure that they correctly implement the protocol.
  4. Periodically tests DAS sources and notifies their administrators if they are unavailable.
  5. Provides a mechanism for activating or highlighting individual DAS services in clients.
