RDF

RDF stands for Resource Description Framework, a model, created by W3C community. It serves for creating resources descriptions, in particular – resources metadata. The main model idea is to use a special kind of statements, expressed by the resource to create its description. The statements are organized into specific structure ‘subject – predicate – object’ named triplet and every part of this statement has some certain meaning. RDF works with concrete objects, their characteristics and facts, similar to the way XML works with abstract materials. But RDF standards describe the logical conclusions that explain how to locate exact facts in the complete data space. This lets RDF index data from separate resources and combine it into groups based on same meaning. The way of presenting data with RDF is relatively simple, so even the computer software can analyze it and make logical conclusions to group the data. This makes RDF a really powerful tool for interchanging data between resources into one general scheme and organizing it.

There are different formats for preparing data for RDF, most widely spread are N3, Turtle, N-Triples, RDFa, RDF/XML. Feel free to visit this page for more information and examples. There are also versions in Russian and Spanish available.
