At Biohackathon2010 , Mark Wilkinson and Luke McCarthy introduced The SADI Framework. From sadiframework.org:SADI is a framework for discovery of, and interoperability between, distributed data and analytical resources. It combines simple, stateless, GET/POST-based Web Services with standards from the W3C Semantic Web initiative. The objective of SADI is to make it easy for data and analytical tool providers to quickly make their resources available on the Semantic Web with minimal disruption to their usual practices.(...)
In the current post, I just want to understand how SADI invokes the services.
The classical Web Services are described using WSDL (Web Services Description Language) and the messages are transported with SOAP.
http://sadiframework.org/registry/ contains all the services handled by the SADI framework. For example calling http://sadiframework.org/services/getPubMedReferencesForPDB returns the following XML document describing the service:
A part of this service can be visualized as a graph:
Calling curl with this file for the service getPubMedReferencesForPDB:
Here, for each PDB entry (input), we were returned a Pubmed Identifier (output).
That's it !
