The Magallanes [23] is a library that can develop effective
workflow discovery engines that can help to collect webservices
which will be used to execute workflow tasks and
it’s datatypes. The discovery of Web services can be based
on syntax description of services or objects that is it’s name
which is often unsatisfactory in bioinformatics because it
presumes knowledge of objects names or semantics services
discovery by specifying a general descriptions about services
or objects which allow to have a more accurate discovery
mechanism. Magallanes uses a syntactic text-based approach
and a semantic approach to collect different services that can
handle the input and output data types.
