What is Eclipse Plug-In for Resource Catalog Browsing?
The concurrent management of both hardware and software resources is often a difficult task. To organize and classify these manageable resources, a coalition of companies defined the WS-ResourceCatalog (WS-RC) specification for Web Services. WS-RC defines a data model that allows for storing manageable resources in a standard way.
The Eclipse Plug-In for Resource Catalog Browsing implements the WS-Resource Catalog data model as defined in the WS-ResourceCatalog specification and provides basic SOAP-based methods for querying the catalog. The plug-in proves that the WS-RC data model can be used to store representations of both manageable hardware resources and software resources. This plug-in enables graphical browsing of a catalog by providing a perspective for basic searching as well as viewing of entries in a Resource Catalog.
The Eclipse plug-in also give the user the ability to find entries of interest, view the entry, and download entry metadata. This metadata could be XML Schema, WSDL, or some other information that further describes the entry in the catalog. If the metadata contains WSDL, the user can create a Web service to interact with the manageable endpoint described in the catalog entry.
How does it work?
The Resource Catalog specification that is now publicly available defines a format for storing resources. Those resources can be software resources or hardware management resources. The Eclipse Plug-In for Resource Catalog Browsing uses the data model as defined in the WS-Resource Catalog specification as a basis for interacting with the resource catalog.
Based on the XML Schema that defines the format of the data stored in the catalog, this Eclipse plug-in code is able to use XPath to search and find entries that match the user's input criteria. After the search results are returned to the user, he can then view the entries using the viewers built in to the plug-in. If the entry has associated metadata, the user can view that metadata as well. If the metadata matches a dialect such as WSDL, the user can then use other built-in capabilities of the eclipse IDE to build a Web service that interacts with the endpoint described in the resource catalog entry.
