List of SPARQL implementations available for querying and manipulating RDF data.
Neo4j is a graph database management system (GDBMS) developed by Neo4j Inc. The data elements Neo4j stores are nodes, edges connecting them, and attributes of nodes ...
Cypher was originally intended to be used with the graph database Neo4j, but was opened up through the openCypher project in October 2015. [ 3 ] The language was designed with the power and capability of SQL (standard query language for the relational database model ) in mind, but Cypher was based on the components and needs of a database built ...
C++, Go, Java, Python: A scalable open-source distributed graph database for storing and handling billions of vertices and trillions of edges with milliseconds of latency. It is designed based on a shared-nothing distributed architecture for linear scalability. [32] Neo4j: 5.26: 2024-12-09 [33]
The resulting graph is a property graph, which is the underlying graph model of graph databases such as Neo4j, JanusGraph and OrientDB where data is stored in the nodes and edges as key-value pairs. In effect, code property graphs can be stored in graph databases and queried using graph query languages.
The Leiden algorithm is a community detection algorithm developed by Traag et al [1] at Leiden University.It was developed as a modification of the Louvain method.Like the Louvain method, the Leiden algorithm attempts to optimize modularity in extracting communities from networks; however, it addresses key issues present in the Louvain method, namely poorly connected communities and the ...
pySHACL - an open source SHACL validator library for command line use written in Python [10] SHaclEX - a Scala implementation of both SHACL and ShEx [11] TopBraid SHACL API - an open source implementation of SHACL by TopQuadrant, based on Apache Jena. It covers SHACL Core and SHACL-SPARQL validation as well as SHACL Advanced Features, SHACL ...
Gremlin is a graph traversal language and virtual machine developed by Apache TinkerPop of the Apache Software Foundation.Gremlin works for both OLTP-based graph databases as well as OLAP-based graph processors.
