The Open Provenance Model is a model of provenance that is designed to meet the following requirements: (1) Allow provenance information to be exchanged between systems, by means of a compatibility layer based on a shared provenance model. (2) Allow developers to build and share tools that operate on such a provenance model. (3) Define provenance in a(More)
SUMMARY The first Provenance Challenge was set up in order to provide a forum for the community to understand the capabilities of different provenance systems and the expressiveness of their provenance representations. To this end, a Functional Magnetic Resonance Imaging workflow was defined, which participants had to either simulate or run in order to(More)
Very large scale computations are now becoming routinely used as a metliodology to undertake scientific research. In this context,)provenance systems' are regarded as the equivazent of the scientist's logbook far in silico ex-perimenlation: provenance captures the documentation of the process that led to some result. Using a protein com-pressibility(More)
T he transition from laboratory science to in silico e-science has facilitated a para-digmatic shift in the way we conduct modern science. We can use computation-ally based analytical models to simulate and investigate scientific questions such as those posed by high-energy physics and bioinformatics, yielding high-quality results and discoveries at an(More)
E-science experiments typically involve many distributed services maintained by different organisations. After an experiment has been executed, it is useful for a scientist to verify that the execution was performed correctly or is compatible with some existing experimental criteria or standards, not necessarily anticipated prior to execution. Scientists(More)
As scientific workflows and the data they operate on, grow in size and complexity, the task of defining how those workflows should execute (which resources to use, where the resources must be in readiness for processing etc.) becomes proportionally more difficult. While " workflow compilers " , such as Pegasus, reduce this burden, a further problem arises:(More)
Provenance is a concept often used in the Art world to refer to the documented history of an artifact, providing information about the artifact's lineage and authenticity. Provenance-aware applications similarly allow their users to have confidence about the data they produce, and can enable users to make judgements relating to notions of trust,(More)
In e-Science experiments, it is vital to record the experimental process for later use such as in interpreting results, verifying that the correct process took place or tracing where data came from. The process that led to some data is called the provenance of that data, and a provenance architecture is the software architecture for a system that will(More)
