Hi everyone, It’s Linh Hoang, the intern from project 3. This week, along with our supervisors, my co-intern and I tried to finalize the YW model with our own vocabulary. We also created an UML diagram to represent the model. This is a good way for outsiders to conceptualize and understand Continue reading Prospective and Retrospective Provenance Queries: Week 6 – Mapping YW & ProvONE model, explore RDF & SPARQL limitations→

Hello everyone, It’s Linh Hoang, the intern from project 3. This week, my co-intern and I continue to focus on revising our YesWorkflow Data Model with our own vocabulary. Besides that, we also created an UML diagram to represent components of the model and how they connects to each other.

However, Continue reading Prospective and Retrospective Provenance Queries: Week 4 – YesWorkflow Data Model→

Hi everyone, It’s Linh Hoang from Project 3. This week, I spent most of my time to read papers and also ran some experiments to explore SPARQL recursive queries capability. The objective is to be able to run standard recursive queries in SPARQL. We found “property path” is a way Continue reading Prospective and Retrospective Provenance Queries: Week 3 – SPARQL Recursive Queries→

Hi all, It’s Linh Hoang from Project 3. This week, I am working on exploring SPARQL querying capabilities in YesWorkflow. The objective is to testing how well SPARQL can query YW outputs, which are represented in RDF format. First, I completed installing Virtuoso on my machine and wrote a manual of Continue reading Prospective and Retrospective Provenance Queries: Week 2 – SPARQL Provenance Query→

My first week internship at DataOne started with a meeting with my mentors Prof. Bertram Ludaescher, Timothy McPhillips and Paolo Missier and my co-intern Hui Lyu. We discussed about what are the objectives of the internship and came up with a list of tasks for the next following weeks. Overall, the objective of the internship is to reimplement existing Continue reading Prospective and Retrospective Provenance Queries: Get to know YesWorkflow→
