Provenance, Lineage, and Workflows
In Computer Science, Provenance also known as lineage and pedigree describe the source and derivation of data. Data provenance is key to the management of scientific data and has recently been recognized as central to the trust one places in data. This paper focus attention on the importance and difficulty of provenance tracking in practice. We discuss a taxonomy of data provenance characterist...
متن کاملWell Constructed Workflows in Bioinformatics
We demonstrate and discuss the advantages of bioinformatical workflows which have no side-effects over those which do have them. In particular, we describe a method to give a formal, mathematical semantics to the side-effect-free workflows defined in SCUFL, the workflow definition language of Taverna. This is achieved by translating them into a natural extension of the Nested Relational Calculu...
متن کاملComposition and Substitution in Provenance and Workflows
It is generally accepted that any comprehensive provenance model must allow one to describe provenance at various levels of granularity. For example, if we have a provenance graph of a process which has nodes to describe subprocesses, we need a method of expanding these nodes to obtain a more detailed provenance graph. To date, most of the work that has attempted to formalize this notion has ad...
متن کاملRecording Actor Provenance Data in Scientific Workflows
The concept of “actor” provenance data – essentially data that a client or service actor may assert about itself regarding an interaction, is presented. Actor provenance data can be combined with assertions of interaction to enable better reasoning within a provenance system. The need for recording and maintaining actor provenance data is discussed, along with the description of an architecture...
متن کاملProvenance in collection-oriented scientific workflows
We describe a provenance model tailored to scientific workflows based on the CollectionOriented Modeling and Design paradigm. Our implementation within the Kepler scientific workflow system captures the dependencies of data and collection creation events on preexisting data and collections, and embeds these provenance records within the data stream. A provenance query engine operates on self-co...
