2 GEOSS Registry
The GEOSS registry is a catalogue service based on ebRIM profile. It supports publication and discovery of services for GEOSS. The endpoint is at
http://uddi.csiss.gmu.edu/
The service is quite self-explained on the portal. It allows a user to register. It also allows a developer to write codes to invoke the discovery service (OGC-compliant).
2.1 Service Publication
There are several steps to register service.
- Create an account
a. The GEOSS Registry requires a user to register and login to publish services. Choose “GEOSS Members” and “Create New User Account”. Fill the following form. You may use OGC as the GEO affiliation.
- Component registration
a. Component* is a term used in GEOSS to represent a system contributed by participants. It should be registered first.
b. The user is only authorized to register a service through its registered component.
- Service registration
a. Select a component that you have the right to register service.
b. Click “Register a Service”, fill the form and register the service.
* A "GEOSS Component" is a part of GEOSS contributed by a GEO Member or Participating organization. Example types of components include observing systems, data processing systems, dissemination systems, educational programmes, or other initiatives. Components may expose service interfaces to provide access to earth observation-related functions and/or data. Components are described in the GEOSS Component Registry.
2.2 Service Discovery
There are two ways to find the service: one is through the portal interface (form-based) and another is through CSW interface. The former one is self-explained. The latter has a webpage dedicated to describe the usage at http://uddi.csiss.gmu.edu/portaldeveloper.htm.
The CSW endpoint is at http://uddi.csiss.gmu.edu:1090/GEOSSCSW202/discovery. Its capabilities can be retrieved through the following request – http://uddi.csiss.gmu.edu:1090/GEOSSCSW202/discovery?Request=GetCapabilities&Service=CSW&Version=2.0.2
