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.
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.
As domain-specific data sets grow, so too grows the need to ensure that their structure is standardized and homogeneous, allowing interoperability between them across the Enterprise. This webinar will cover how knowledge graphs can help facilitate this unification. We will discuss the widely accepted standards knowledge graphs use, how they can be utilized to create domain-specific standard models, and some of the best practices and considerations to use in doing so.
