Interface LPG2RDFConfiguration

All Known Implementing Classes:
DefaultLPG2RDFConfigurationImpl, LPG2RDFConfigurationImpl
public interface LPG2RDFConfiguration
Represents the notion of an LPG-to-RDF configuration as defined in Olaf Hartig: "Foundations to Query Labeled Property Graphs using SPARQL*." In the Proceedings of the 1st Int. Workshop on Approaches for Making Data Interoperable (AMAR) at SEMANTiCS 2019. https://ceur-ws.org/Vol-2447/paper3.pdf Such a configuration consist of the following five components, which are captured by the methods of this interface. i) an injective function called node mapping that maps every given LPG node to either an IRI or a blank node, ii) an injective function called node label mapping that maps labels of LPG nodes to IRIs or literals, iii) an injective function called edge label mapping that maps labels of LPG edges to IRIs, iv) an injective function called property name mapping that maps names of properties of LPG nodes and edge to IRIs, and v) an IRI to be used in the predicate position of any RDF triple that captures information about the label of some LPG node.

    Returns true if the given IRI is in the image of the property name mapping and, thus, may be returned by getIRIForPropertyName(String) for some property name.
    boolean
    isRDFTermForLPGNode(org.apache.jena.graph.Node term)
    Returns true if the given RDF term is in the image of the node mapping and, thus, may be returned by getRDFTermForLPGNode(LPGNode) for some LPG node.
    boolean
    isRDFTermForNodeLabel(org.apache.jena.graph.Node term)
    Returns true if the given RDF term is in the image of the node label mapping and, thus, may be returned by getRDFTermForNodeLabel(String) for some node label.
