# Extended Functions

The data defined in the Semantic SBT contract is compatible with the RDF specification. So, when a SBT is generated, we can also insert the relevant data into a graph database by using an on-chain monitoring service. With Relation Graph, an on-chain graph database developed by Relation, we can easily port all data fitting the semantic contract specification into the graph database, which can be efficiently queried using the generalized SPARQL language. It can also be queried in a relational manner with open APIs, providing more flexible options for third-party projects.
