fragment_downloaded_cb({"url":"nie-ontology.html#introduction","fragment":"Introduction\nThe core of the NEPOMUK Information Element Ontology and the entire\nOntology Framework revolves around the concepts of nie:DataObject and\nnie:InformationElement. They express  the representation\nand content of a piece of data. Their specialized subclasses (defined\nin the other ontologies) can be used to classify\na wide array of desktop resources and express them in RDF.\nnie:DataObject class represents a bunch of\nbytes somewhere (local or remote), the physical entity that contain\ndata. The meaning (interpretation) of that entity, the\ninformation for the user contained in those bytes (e.g. a music file,\na picture) is represented on the\nnie:InformationElement side of the\nontology.\nBoth sides are linked using the\nproperty nie:interpretedAs (and its reverse\nnie:isStoredAs), indicating the correspondence\nbetween the physical element and its interpretation. There is also a\nproperty to\nlink nie:InformationElements,\nrepresenting the logical containment between them (like a picture and\nits album).\n"});
