Service to generate Big Data analytic workflow, leveraging specific needs and restrictions of the domain and design issues, identifying necessary data sources, formats, treatment, integration, and standardisation. Furthermore, providing mechanisms for the publication and preservation of curated data and results. This service is conceived in the form of SaaS (Software as a Service) and will be oriented to constructing analysis applications through component workflows and a Web interface. This interface will offer mechanisms to compose workflows in an essay and intuitive way, although with practical functionality. In the design of these workflows, thanks to the semantisation of metadata involving software components (other services), the user will be guided in its composition and how it can be deployed and executed.
