Week-5-Update

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

Week-4-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

Prospective and Retrospective Provenance Queries: Week 4 – YesWorkflow Data Model

Hi everyone, I’m Linh Hoang, from project 3. This week, my co-intern and I focused on creating a YesWorkflow Data Model with our own vocabulary. Previously, we used ProvONE Data Model (which is an extension of the standard Provenance Data Model recommended by W3C) to represent items of YesWorkflow. However, Continue reading Prospective and Retrospective Provenance Queries: Week 4 – YesWorkflow Data Model

Prospective and Retrospective Provenance Queries: Week 3 – SPARQL Recursive Queries

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

Week-3-Update

This is the third week of my internship. I felt much comfortable to work with the professors and my co-partner. We basically made progress in schedule. For this week, given the elementary model structure in RDF/Turtle file for simulate_data_collection example of YesWorkflow, I further improved the RDF/Turtle data model by Continue reading Week-3-Update

Prospective and Retrospective Provenance Queries: Week 2 – SPARQL Provenance Query

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

Prospective and Retrospective Provenance Queries: Get to know YesWorkflow

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
