The last chapter introduced how to acquire RDF data from the blockchain. This chapter will show how to parse these RDF data.
Data filtering
covers a lot more ground than the Relation Protocol does. So, we will filter the events shown in the last chapter.
Graph Indexer will parse the RDF data conforming to .
This is to say that the address returned by the contract's schemaURI() method must exist in for it to be parsed by the Graph Indexer.
In the , the process to acquire a Schema is defined:
interface ISemanticRDFSchema {
/**
* @notice Get the URI of schema for this contract.
* @return The URI of the contract which points to a configuration profile.
*/
function schemaURI() external view returns (string memory);
}
