DILIGENT Resources and profiles
A DILIGENT Resource is anything whose related information can be gathered, stored, monitored, and disseminated in order to provide the valuable amount of knowledge needed during the creation and management of a VDL as well as to operate the entire DILIGENT infrastructure. The following resources have been identified:
- VDL
- Collection
- Metadata Collection
- Transformation Rule
- Service
- Running Instance
- External Running Instance
- DHN
- CS
- CSInstance
- gLite resource
Such resources can be combined or created at VDL creation time in order to set up a new Virtual Digital Library. In order to be appropriately managed and discovered, a DILIGENT Resource has to be described by creating a profile document compliant with its XML schema. A Schema per each resource type has been defined and all of them are available in the CNR's SVN Repository In the following, we will focus about how to compile service profile
Service profile
Usually, a Service is defined as a software system that delivers functionalities. In DILIGENT, a Service is composed by a not-empty set of related Packages (connected through dependencies) forming an unique logical entity. A Package is the smallest installable unit of software that can be deployed on a DHN. Packages are the way in which the software needed to set up a DL has to prepared in order to be used and stored in the system.
Composition
The set of Packages forming a Service is composed by:
- one and only one Package of WSRFService or Portlet type (the main package or the entry point)
- an arbitrary number of other Packages of different type logically related (even if not used) by it.
