GraphDB 9.2 upgrades the modelling expressivity of the database with RDF-Star/SPARQL-Star – the most widely supported extension of those standards, which will be part of RDF 1.2. In RDF-Star, one can make statements about statements, formally called statement-level annotations. For example, one can provide a period for an employment relationship like this: (Joe works-for BigBucks) from 1/1/2018 to 30/3/2020. This mechanism goes beyond the expressivity of the Property Graphs, where one can attach key-value pairs to relationships. The statement-level annotations enable a more efficient representation of scores, weights, temporal restrictions and provenance information.
The RDF-Star/SPARQL-Star was initially developed as a specification enabling the RDF model to match the expressivity of the property graph models and assign meta-data on the RDF statement level. In this talk, Vassil will give a practical tutorial on the various options to model statement-level meta-data and what’s new in GraphDB 9.2.
The webinar will demonstrate the various options to model statement-level meta-data and what’s new in GraphDB 9.2.
Who is this webinar for:
- Technology enthusiasts (architects, software developers);
- Ontologists and data scientists;
- Technical people confident in SPARQL;
- Consultants and Solution Architects;
- Linked Data Scientists.
