Data Validation and SHACL
Join this Stardog training webinar to learn the basics of SHACL (Shapes Constraint Language) and how to validate RDF graphs with SHACL. This training is intended for those who are familiar with RDF and for those would like to learn how to detect data consistency and quality issues in RDF graphs. SHACL is a W3C recommendation that provides a declarative language for specifying constraints over RDF graphs.
Reasoning with RDF Graphs and Ontologies
This training is intended for those who have some familiarity with RDF and would like to learn how to use reasoning for enriching the RDF graphs with new inferences.
Getting Started with Virtual Graphs
Join this training webinar to learn how to map relational data sources to the RDF graph model and query external relational data sources as virtual graphs. Stardog supports the standard W3C R2RML mapping language for defining how data in a relational system maps to RDF graphs. We’ve created the Stardog Mapping Syntax to simplify the process of writing these mappings. Once the mapping is created, Stardog seamlessly supports both federation (live query) and materialization (extraction) methods to access relational data.
