Welcome to Gridpedia, featuring a RDF ontology for the Smart Grid!

Gridpedia is different from other ontologies, as it allows users to collaboratively define concepts (in a structured and unstructured manner). That is, users may model a concept via unstructured text (e.g., a definition), but also via structured information (e.g., relations of a particular concept to other concepts). The contents of Gridpedia are exported (as a stable knowledge base dump) via RDF/XML format and thus may be used in any other tool or context. GridPedia features already a lot of content: There are currently 0 classes, 0 properties, and 0 instances defined. You should contribute, too!
