This service is established to generate Big Data analytic workflow by leveraging specific needs and restrictions of the domain and design issues, and identifying necessary data sources, formats, treatment, integration, and standardisation. Furthermore, it provides 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 specific web interface. The latter will offer mechanisms to compose workflows in a straightforward and intuitive way, although with practical functionality. During 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 execution.
