Watch the Service Catalogue Perspective video.
The Service Catalogue Perspective allows you to access the functionality of service catalogues, such as the BioCatalogue, from within the Taverna Workbench. By default, Taverna will connect to the BioCatalogue at http://www.biocatalogue.org/, but this is configurable through preferences (more on how to do this later on).
The service catalogue typically contains annotated Web services - WSDL/SOAP and REST Web services. The search you perform will search over both and the results are represented in two separate tabs in the Perspective - one for WSDL and one for REST services.
Keyword (Free Text) Search
To perform a free text search using keywords:
1. Simply enter your search terms separated by a blank character in the search box in the top right corner of the window.
To filter down keyword search or simply to apply a filter to all services in the catalogue:
1. Tick one or more tags on the left hand side of the window.
Clearing Search Results
To clear the search results and filters you may have applied:
1. Click the Clear button next to the search box.
Actions on Search Results
Once you have found the services you wanted, you can do various useful things with them by using the actions toolbar located in the search tabs.
For WSDL services only, adds all associated services to the Service Panel so they can lated be drag-and-dropped into workflows. Typically, a WSDL Web service will have several operations (although it can have only one). This action enables you to add all "sibling" operations that belong to the same "parent" Web service all in one go (as they are probably related and can work together).
Inserts the service directly into the current workflow.
Provides latest monitoring information about the service from the Catalogue. Services are typically monitored twice a day and this gives the report of the overall service status - the availability of the service, how often the service test failed recently, etc. This gives you a pretty good idea if the service is up and running and how reliable it is.
This action opens the selected service in actual catalogue by firing up a Web browser. This way you can get more detailed information about the service.
Service Catalogue Preferences
The Service Catalogue preferences control what information you see when using the Service Catalogue Perspective. For example, you can modify the service catalogue instance Taverna will connect to through preferences.
