Security Proxy for OGC Services like WPS.
Project description
- Twitcher (the bird-watcher)
a birdwatcher mainly interested in catching sight of rare birds. (Leo).
Twitcher is a security proxy for Web Processing Services (WPS). The execution of a WPS process is blocked by the proxy. The proxy service provides access tokens (uuid, Macaroons) which needs to be used to run a WPS process. The access tokens are valid only for a short period of time. In addition one can also use X.509 certificates for WPS client authentication.
The implementation is not restricted to WPS services. It will be extended to more OWS services like WMS (Web Map Service) and CSW (Catalogue Service for the Web) and might also be used for Thredds catalog services.
Twitcher extensions:
Twitcher is a prototype implemented in Python with the Pyramid web framework.
Twitcher is part of the Birdhouse project. The documentation is on ReadTheDocs.
