DiscoBits Editor 3 0 2 2 Using RDF models often involves associating things of the described world to data that can be shown - or made perceivable by other means - to a user. By doing so an entity of the described domain (e.g. a foaf:Person) is linked to a describing node, the latter would typically be a literal or a dereferenceable URI. 0 3 While using dereferenceable URIs keeps the describing entities ouside the model it offers the advantage of the protocol used to get the represenation. Using content and language negotiatiation the represantation will be optimized for the abilities of the device and of the user. The classes d:InfoBit and d:DiscoBit are the main classes of the ontology, the prefix "d:" refers to the namespace http://discobits.org/ontology#. 1 DiscoBits - beyond literals Discobits allows to bring describing entities into the model an express relationships similar to multipart-mime message (RFC 2045). It can express that an entity contains different other entities and about the role an entity plays with a containing entity. Such a describing entity is a DiscoBit. A DiscoBit is not necessarily a n entity of description it may also be a novel, a movie or something else that's rather creating than describing. The InfoBit is something that can be made perceivable by a computer. For example the interpretation as image/gif of some bytes is an InfoBit. Any RDFS Literal is an InfoBit. An InfoBit has no content or meaning beyond the mere set of possible representations to a user. InfoBits are the lowest common denominators of the modeled world, an image, a sound, a text, a program. Motivation 1 When humans say things about InfoBits that weren't inferable beforehand to the system, they create DiscoBits ('Disco' stands for 'Discourse') . A file in a directory is a DiscoBit by creating a functional role associated to a specific InfoBit. A DiscoBit either refers to one InfoBit, or to a set entries (d:Entry) which refer to other DiscoBits. These entries describe either parts or variants of the containing DiscoBit.

1 DiscoBits and InfoBits 1 A DiscoBit is said to contain the DiscoBits hold by its entries and recursively the DiscoBits contained by those. A DiscoBit never contains itself. 0 2 A course grained but extensible ontology for modeling the kind of information we deal with on the web, in emails and filesystems. The aim is to model the data of the different systems in a way they share an ontology describing the generic concepts. Such an ontology allows dealing with information resources in a straight-forward manner when merging the data from various sources in an RDF-graph. 1 The DiscoBits Editor is a javascript application that allows editing DiscoBits. 0 0 1 1 0 0
