The document discusses the Cancer Biomedical Informatics Grid (caBIG), a platform by the National Cancer Institute for enhancing access to bioinformatics data and tools in cancer research. It highlights the integration of caBIG services into the Taverna workflow system, which enables users to build workflows by connecting various services, including web services and local scripts. Additionally, it details the security features of the setup and provides examples of use cases, such as a lymphoma prediction workflow.

2. What is caBIG?Cancer Biomedical Informatics GridBiomedical platform by National Cancer Institute (NCI) in USLinking cancer institutes and research organisations across the countryImproving the US cancer research communitity’s access to bioinformatics data and tools.

3. caBIG services~120 service providers across US

4. caBIG services75 data services53 analytical servicesData types semantically described using a controlled vocabolary – Silver level compatibilityServices registered in an Index Service, with service metadata (caDSR)Security infrastructure (GAARDS), delegation service, single sign-onThus – forming a grid - caGrid

6. Taverna useUsed by eScientists in fields such as:BioinformaticsChemistry and cheminformaticsAstronomyText miningSocial sciencesMusic.. and more

7. Connecting servicesTaverna is oblivious to the science, workflows are built by dragging and dropping how the data should flow between different servicesWeb ServicesLocal scriptsJava APIsR.. other customized invocation mechanisms
