Graph Fundamentals — Part 1: RDF

Description: IBM Graph is an enterprise-grade property graph as a Service that is built on open-source database technologies. Linked data rely on RDF graphs that contain data in RDF format. The URI can be a URL pointing to a web resource, or it can contain arbitrary data.Data in an RDF database using named graphs is organized into multiple, distinct graphs, each identified by a unique URI. I’ve been researching which graph database technology to use for a project.There are two major variants of graph databases in the wild — RDF graphs (aka triple-stores) and Labelled Property Graphs.Graph database users today face a choice between two technology stacks: the Resource Description Framework (RDF), on one side, is a data model with built-in semantics that was originally developed by the W3C to exchange interconnected data on the Web; on the other side, Labeled Property Graphs (LPGs) are geared towards efficient graph processing and .Schlagwörter:Graph DatabasesKnowledge Graphs
