Bioinformatics has moved from command-line standalone
programs to web-service based environments. Such trend has resulted
in an enormous amount of online resources which can be hard to find
and identify, let alone execute and exploit. Furthermore, these resources
are aimed -in general- to solve specific tasks. Usually, this tasks need to
be combined in order to achieve the desired results. In this line, finding
the appropriate set of tools to build up a workflow to solve a problem
with the services available in a repository is itself a complex exercise. Issues
such as services discovering, composition and representation appear.
On the technological side, mobile devices have experienced an incredible
growth in the number of users and technical capabilities. Starting from
this reality, in the present paper, we propose a solution for service discovering
and workflow generation while distinct approaches of representing
workflows in a mobile environment are reviewed and discussed. As a
proof of concept, a specific use case has been developed: we have embedded
an expanded version of our Magallanes search engine into mORCA,
our mobile client for bioinformatics. Such composition delivers a powerful
and ubiquitous solution that provides the user with a handy tool for
not only generate and represent workflows, but also services, data types,
operations and service types discovery
