    1. EU PROVENANCE project: an open provenance architecture for distributed applications Javier Vázquez-Salceda 4th Workshop on Agents Applied in Health Care August 28, 2006

    2. 2 Problem Domain In distributed medical applications the following information is split into different administration domains (islands of information) The medical data (HC history of patients) The workflows (of the corresponding processes carried out to patients) The logs (recording meaningful events) An integrated view, not only for data but also for workflows and logs is needed To have an integrated view of a patient’s treatment across all institutions To analyse the performance of distributed HC services to detect problems to solve To carry out audits of the system, if requested by medical or legal authorities.

    3. 3 Problem Domain Need: to trace back The origins of (medical) decisions and processes The (medical) information available a each step The origins of such information Idea: make the distributed medical system provenance_aware Our def: “Provenance of a piece of data is the process that lead to the data” Re-convert standard logs into provenance-based logging services capable to record information about the workflow execution and the data, and their provenance. Adapt the medical systems to provide provenance information. Have tools to properly reconstruct the full provenance of data

    4. 4 Aims of EU PROVENANCE project Define core concepts pertaining to provenance Specify functionality required to become “provenance-aware” Define open data models and protocols that allow distributed systems to inter-operate Standardise data models and protocols Provide a reference implementation Provide reasoning capabilities over provenance data (higher-level queries)

    5. 5 Target: Service Oriented Architectures Covering not only Multiagent Systems but other SOA’s (Webservices, GRID) Service Oriented Architectures approach Broad definition of service as component that takes some inputs and produces some outputs. Services are brought together to solve a given problem typically via a workflow definition that specifies their composition. Every application is made up of actors Every change that happens is an action by an actor Actors communicate by sending messages Every action is triggered by a message The outputs of (messages sent by) an actor are caused by the inputs to (messages received by) the actor

    6. 6 Use cases Aerospace engineering: maintain a historical record of design processes, up to 99 years.

    8. 8 An Example If actors are black boxes, these assertions are not very useful because we do not know dependencies between messages If actors are black boxes, these assertions are not very useful because we do not know dependencies between messages

    10. 10 Conclusions Provenance may increase the quality of Agent-mediated Health Care services: trace back the origin of (medical) decisions and actions provide an integrated view of a patient’s treatment Issues Connect an electronic computational process with real world Connect past electronic computational processes Currently building a full demonstrator for the Catalan OTA as a use case for EU PROVENANCE Evaluation is planned with some hospital and transplant coordinators in the Barcelona area.
