## Why It Matters
Ontopic matters because it is focused on Virtual Knowledge Graphs, a software approach that connects knowledge-graph-style querying with existing data sources. In the provided material, Ontopic is linked to ontop, a platform designed to query relational databases as Virtual RDF Knowledge Graphs using SPARQL. This positions Ontopic in a space where organizations can work with relational data using semantic technologies and graph-oriented query patterns, without necessarily requiring that data to be physically transformed into a separate graph store. Ontopic’s relevance is also reflected in its public presence (website and multiple social channels), which supports discoverability and engagement around Virtual Knowledge Graph technology. For practitioners and researchers working with SPARQL, RDF, and relational databases, Ontopic is notable as a company explicitly centered on this “virtual” knowledge graph paradigm and connected to a concrete querying platform (ontop) described in the source material.
