Special Issue: The First Provenance Challenge
TLDR
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. Expand

Provenance in Scientific Workflow Systems
TLDR
We propose the implementation of SemEQUAL using OrdPath to represent position within the Wordnet hierarchy, leveraging its ability to compute transitive closures efficiently. Expand

Addressing the provenance challenge using ZOOM
TLDR
This paper discusses the design and implementation of ZOOM in the context of the queries posed by the provenance challenge, and shows how user views affect the level of granularity at which provenance information can be seen and reasoned about. Expand

Scientific workflows for computational reproducibility in the life sciences: Status, challenges and opportunities
TLDR
We characterize and define the criteria that need to be catered for by reproducibility-friendly scientific workflow systems, and use such criteria to place several representative and widely used workflow systems within such a framework. Expand

Zoom*UserViews: Querying Relevant Provenance in Workflow Systems
TLDR
We present the ZOOM*UserView system, and focus on the module which generates a "user view" based on what tasks the user perceives to be relevant in the workflow specification. Expand

Querying and Managing Provenance through User Views in Scientific Workflows
TLDR
We formalize the notion of user views, demonstrate how they can be used in provenance queries, and give an algorithm for generating a user view based on which tasks are relevant for the user. Expand

Differencing Provenance in Scientific Workflows
TLDR
We present efficient, polynomial-time algorithms for differencing executions of the same specification and thereby understanding the difference in the provenance of their data products. Expand

Search, adapt, and reuse: the future of scientific workflows
TLDR
We argue that a wider adoption of SciWFM will only be achieved if the focus of research and development is shifted from methods for developing and running workflows to searching, adapting, and reusing existing workflows. Expand
