VO Resources

Several VO-level services require specific configuration at VO scope in order to be functional. This “Configuration” is modelled as a gCube Resource and kept in the Information System.

Each resource is a centralized configuration unit called Generic Resource. The payload is usually a service-specific XML and new (not currently existing) services can register their own generic resources.

There exist mandatory VO Resources and optional VO Resources. Many of the mandatory resources are prerequisites for the bootstrapping process of the Information Retrieval area.

Mandatory VO Resources

The following resources are mandatory to be registered in any VO scope:

• VRE Modeler resource: this resource is used at VRE Definition time. A VRE Designer can easily generate new VREs through the VRE Definition portlet; here, she/he selects the functionalities (portlets and services) that will be made available to the VRE users, from the list of available functionalities in the VO. This list of VO functionalities is stored in the VRE Modeler resource;
• Transformation Programs: the Metadata Broker and gDTS services provide the functionality to transform various types of data to other formats. A Transformation Program resource describes details about a specific transformation that can be applied to a Metadata Schema format. The transformation services use these resources in order to understand how the input data should be handled and transformed;
• Transformation XSLTs
• Index types
• AIS scripts
• IRBootstrapper configuration
• Default user profile
• Metadata XSLTs
• Presentation XSLTs
• Metadata schema info
• Portal layout

Optional VO Resources

The following resources can be optionally registered in a VO scope:

• ISFilters
