There are many connections between model and recon facts, and many possible ways should also be considered by virtue of FILTER \/ FILTER NOT EXISTS \/ UNION clause query statements. Besides, the common ancestors and lowest common ancestor (LCA) questions in Datalog language are complex when implementing in SPARQL query engine. I did a lot of research on dealing with recursive queries and complicated filter queries in SPARQL. I feel that one of the apparent features of SPARQL language is the repeat-ability of subjects and objects in the statements even if different names are used for them.<\/p>\n<h2>2. <a href=\"https:\/\/github.com\/idaks\/DataONE-Prov-Summer-2017\/tree\/master\/examples\/simulate_data_collection\/YW%20Model%20OWL\">YesWorkflow Data Model Vocabulary<\/a><\/h2>\n<p>For the YesWorkflow Model vocabulary, we thought about differentiating the &#8220;connectsTo&#8221; relationship between Port and Data. In other words, we intended to use &#8220;yw:reads&#8221; association between InPort and Data, and to use &#8220;yw:writes&#8221; between OutPort and Data, which could make it more reasonable for semantic understanding. While, we are still under discussion about thinking of a way to connect retrospective Resource to prospective classes. The URIVariable of Resource and the Data actually share the same name, but currently they are in retrospective and prospective world respectively.<\/p>\n<p>For the following weeks, I suppose to think about a proper deliverable product for our summer intern work.<\/p>\n<p>Hui<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The main task for this week is still updating the YesWorkflow Model Vocabulary and Structure, and modifying SPARQL queries for advanced questions.
