Category Archives: Prospective and Retrospective Provenance Queries

Hi everyone, It’s Linh from project 3 again. This is my last week at DataONE as a summer intern. Most of the time, I spent on wrapping up our works, including: reorganize the GitHub repository, writing the internship final report simultaneously with a workshop paper. Our team intend to submit Continue reading Prospective and Retrospective Provenance Queries: Week 9 – Wrapped up week, internship final report & paper producing!→

This the last week of my DataONE summer intern, but it is not the end. I will plan to present our work by research poster in late August for DataONE All Hands Meeting, especially the provenance event. During this week, I firstly updated the RDF Turtle files following our most Continue reading Week-9-Update→

During this week, we had an intensive discussion about the YesWorkflow Data Model vocabulary. Finally, we came to a conclusion that we should adopt the following predicates between Port, Data and Resource. <Port> yw:sends/yw:receives <Data> <Data> yw:wasReadFrom/yw:wasWrittenTo <Resource> To distinguish prospective and retrospective provenance, we used two different RDF Turtle Continue reading Week-8-Update→

Hi all, It’s Linh Hoang, the intern from project 3 (again 🙂 ). Time flies! And we are reaching the last few weeks of the internship! This week, we mainly spent time for fine-tuning our YW Model. Some minor changes were made for naming convention purposes. Also documentations of the model including Continue reading Prospective and Retrospective Provenance Queries: Week 7 – Fine-tuning YW Model & SPARQL queries→

The main task for this week is still updating the YesWorkflow Model Vocabulary and Structure, and modifying SPARQL queries for advanced questions. This is our GitHub repository including the Model Specification, RDF Turtle facts, and SPARQL queries: simulate_data_collection example 1. YesWorkflow SPARQL Queries For the SPARQL queries, the combined queries Continue reading Week-7-Update→

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→

During this week, interns and mentors had an intensive discussion about the YesWorkflow Model vocabulary and its mapping to ProvONE Model. A critical distinction between YW and ProvONE is that YW has three types of ports, while ProvONE only has the general class port. Therefore, I created a hierarchical model Continue reading Week-6-Update→

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. The diagram is Continue reading Prospective and Retrospective Provenance Queries: Week 5 – YW Data Model & SPARQL queries (cont.)→

During the middle week of my intern, I continued working on improving the YesWorkflow Conceptual Model vocabulary and structure. As suggested by my primary mentor, I utilized Markdown format combined with HTML tags to create the model vocabulary documentation table to make it machine-readable. I also created another table for Continue reading Week-5-Update→

During this week, I further improved the RDF model for YesWorkflow model facts. Especially, I introduced three self-defined associations (yw:isAssociatedWith, yw:filePath, yw:portType) and one class (yw:Data). These namespaces can help me to distinguish input ports, output ports and parameters, and to connect data with URI templates to corresponding ports. To Continue reading Week-4-Update→
