BioMedBridges deliverable 4.1 described summary scientific use cases for the federated web service strategy for integration by WP4. For the present deliverable, this work was expanded on by: examining the technical status of the WP4 contributors and other partners within BioMedBridges and assessing whether the technical plan is feasible determining which use cases can be delivered with existing technology and which will require de novo development of web services and clarifying external dependencies, such as e.g. authentication software for WP5 or limitations imposed by the RDF technology to be adopted in the latter stages of the project. As there are dependencies between WP3 (standards) and WP4 (technical integration), a joint survey was circulated to all participating research infrastructures to assess the current use of standards, the scientific use cases, the technical approach within each infrastructure, and the current uses of research data. The survey questions, results and a summary are included in Appendix 1, 2 and 3 to this document and are analysed here. In addition, a joint technical workshop was organised by WP3 and 4 that was also attended by WP5 members and members of the use cases. The results from this workshop, a report of which is included in Appendix 4 to this document, have flown into this deliverable and will make a significant contribution towards the further development of the technical integration strategy within the project.
