During this year’s DataONE summer project, our primary goal was to develop a provenance repository and an interface to interactively browse the provenance graphs. The summer project team met with members of the Provenance Working Group (ProvWG) during June this year at the University of California Davis and found the Continue reading Final Update
We finally got our whole app working together so we are just debugging the last couple functions right now. Last week we got the app working for some basic test cases (add a run to the db, retrieve a run back and display the graph). This weekend we got more Continue reading Weekly Update
Last week, I attended the SSDBM 2011 conference at Portland, OR, USA. I presented our work “PROPUB: Towards a Declarative Approach for Publishing Customized, Policy-Aware Provenance”. In this work, we show how to balance between (i) the desire to publish provenance data so that collaborators can understand and rely on Continue reading Weekly Update
This week I have been working on rewriting storage and retrieval in the Neoj4 database to make it easier to draw the graphs using Graphviz. It took much longer than expected because of problems I was having with Neo4j, but I have completed storage of a Run object (which represents Continue reading Weekly Update
Last week, I was busy with primarily with three activities. First, I worked with Michael W to complete the design for the upload and query pages. He is working on the implementation of these two pages. As of now, the upload page would allow to upload trace files from various Continue reading Weekly Update
We maintain a small bibliography of publications that are relevant to this project. The Mendeley link to its contents is here.

Welcome to the DataONE Summer Internship project on Scientific Workflow Provenance. The goals of this project are to develop a provenance repository system for publishing and sharing data provenance collected from runs of a number of scientific workflow systems (Kepler, Taverna, Vistrails), together with a provenance trace publication system that allows Continue reading Provenance Repository and Publishing Toolkit Project
Scientific Workflow Provenance Repository and Publishing Toolkit Scientific workflow systems are increasingly used to automate scientific computations and data analysis and visualization pipelines. An important feature of scientific workflow systems is their ability to record and subsequently query and visualize provenance information. Provenance includes the processing history and lineage of Continue reading About Our Project
