Comparing Grakn to Semantic Web Technologies — Part 2/3

This is part two of Comparing Semantic Web Technologies to Grakn. In the first part, we looked at how RDF compares to Grakn. In this part, we look specifically at SPARQL and RDFS.

What Is SPARQL?

SPARQL is a W3C-standardised language to query for information from databases that can be mapped to RDF. Similar to SQL, SPARQL allows to insert and query for data. Unlike SQL, queries aren’t constrained to just one database and can be federated across multiple HTTP endpoints.
