Applying the Virtual Data Provenance Model
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
To support such analyses, we have developed a "virtual data system" that allows users first to define, then to invoke, and finally explore the provenance of procedures (and workflows comprising multiple ...
This property makes it straightforward for the virtual data system to record not only the recipe for producing any given data object but also sufficient information about the environment in which the recipe ...
We acknowledge the contributions to this work of Jens Voeckler, Jed Dobson, and members of the QuarkNet project. ...
