For a more detailed look at RDF, see RDF in Depth on this site, which this page was based on.Two video introductions to the Semantic Web and RDF and RDFa by Manu Sporny are very good.Ian Davis's RDF Tutorial slides are also very good.There is also a Russian translation of this page.

RDF is a method for expressing knowledge in a decentralized world and is the foundation of the Semantic Web, in which computer applications make use of distributed, structured information spread throughout the Web. Just to get it out of the way, RDF isn't strictly an XML format, it's not just about metadata, it has little to do with RSS, and it's not as complicated as you think. The Big Picture RDF is a general method to decompose any type of knowledge into small pieces, with some rules about the semantics, or meaning, of those pieces. @prefix : < . Conclusion. Graph database. Database that uses mathematical graphs to store and search data Graph databases differ from graph compute engines.

Graph databases are technologies that are translations of the relational online transaction processing (OLTP) databases. On the other hand, graph compute engines are used in online analytical processing (OLAP) for bulk analysis.[5] Graph databases attracted considerable attention in the 2000s, due to the successes of major technology corporations in using proprietary graph databases,[6] along with the introduction of open-source graph databases. One study concluded that an RDBMS was "comparable" in performance to existing graph analysis engines at executing graph queries.[7] History[edit] Graph structures could be represented in network model databases from the late 1960s. Labeled graphs could be represented in graph databases from the mid-1980s, such as the Logical Data Model.[10][11] Commercial object databases (ODBMSs) emerged in the early 1990s.
