3. PHARMA objectives 3 Design and development of a WEB APPLICATION EXPLOITING the WEB OF DATA for the CREATION, MANAGEMENT and REUSE of PERSONAL HOSPITALIZATION RECORDS
4. Background 4 Web of Documents evolves in the Web of Data Reuse of information fragments via the Web Reuse of Personal Private Information on a Web-wide scale poses problems of security and privacy and limits the widespread diffusion of e-government applications
5. Objectives Design a develop a e-health application on top of a Web of Data infrastructure allowing the distributed management of Hospitalization Records Demonstrate its validity and applicability in a security and privacy safe way on a Web scale thus paving the way for its wider reuse in the more general Personal Health Record (PHR). 5
6. Project Steps 6 Design and development of the application for the management of hospitalization records on top of a Web of Data infrastructure (InterDataNet) Analysis of the hospitalization record Integrated Therapeutic Chart (ITC) Definition of a the hospitalization record conceptual model Analysis and definition of the application workflow Use cases and sequence diagrams Application implementation Design and development of the GUI Design and development of the interconnection with the IterDataNet infrastructure Use Cases validation in real settings
8. A complete and accurate summary of the health and medical history of an individual by gathering data from many sources and making this information accessible online to anyone who has the necessary electronic credentials to view the information. Personal Health Record (PHR) 8 PHR
9. A complete and accurate summary gathering all the personal data and meaningful clinical information related to a patient and to a single hospitalization episode (Italian Health Ministry, 1992). Hospitalization Records (HR) 9 HR PHR

23. PHARMA – the application Is a Firefox plugin Is a Web application exploiting the services offered by the InterDataNet middleware security, privacy, versioning, replica, provenance, licensing Allows asynchronous collaboration between different distributed actors in the hospital Data are structured into documents Hospitalization records, integrated therapeutic charts Data are on the Web Identified by HTTP URI Reusable and manageable through HTTP operations (GET,PUT,POST,DELETE) 23
24. InterDataNet InterDatanetis an extension of the Web aiming to realize the Web of Data to allowcollaboration and reuse of complex information resourcesstructuredintodocuments 24
25. 25 Is a four layer architecture The top layer manages data structured into documents and offers APIs to Applications. The bottom layers provide a Web resource abstraction for every single data to be reused. The intermediate layers provide further collaboration-enabling services (versioning and replica management.)
27. InterDataNetfeatures General-purpose approach to data integration and interoperability Based on a flexible Information Model (IDN-IM) Hinging around the use of «documents» Enables collaboration through sharing of structured documents Provides infrastructural services to support workflows development Scalable at a Web level Provides configurable replication and versioning services Supports privacy, provenance and security
