Semantics describes MarkLogic’s ability to store graph data as RDF Triples—a new approach to modeling data that focuses on relationships. Storing RDF enhances MarkLogic’s document model by providing a smart way to connect and enhance the JSON and XML documents that MarkLogic stores. This is important for data integration and better querying. Semantics also provides context for data by providing a smart way to store metadata. For example, consider a database that has information about parts, and one part is listed with a size of “42.” But, where is the contextual information: What are the units of “42”? What is the tolerance? Who measured it? When was it measured? Who can see this data? That contextual information is the semantics of your data, and is easily stored in MarkLogic as RDF triples.
