Converters may be part of a one-time migration effort, or part of a running system which provides a semantic web view of a given application. See also: RDFImportersAndAdapters Please add converters as you make them or hear of them. Formats in alphabetical order: BibTex BibTex is the format for bibliographic references in TeX. BibBase transforms BibTeX files (given in a URL) into Linked Data with RDF/XML output support. Bittorrent is alas now 404 (in 2007). CSV (Comma-Separated Values) See also: Flat Files and TSV An RDF Extension is available for Google Refine. Debian The package information in Debian and similar systems (Ubuntu, Fink, etc), with its general usefulness and its graph-like nature, is a clear candidate for conversion to RDF. See VitaVoni blog about this. email2rdf transforms email mbox files into RDF/XML. Excel See JPEG. An Intrepid Guide to Ontologies. Ontology is one of the more daunting terms for those exposed for the first time to the semantic Web.

An Intrepid Guide to Ontologies

Not only is the word long and without many common antecedents, but it is also a term that has widely divergent use and understanding within the community. It can be argued that this not-so-little word is one of the barriers to mainstream understanding of the semantic Web. The root of the term is the Greek ontos, or being or the nature of things.

Literally — and in classical philosophy — ontology was used in relation to the study of the nature of being or the world, the nature of existence. Tom Gruber, among others, made the term popular in relation to computer science and artificial intelligence about 15 years ago when he defined ontology as a “formal specification of a conceptualization.” There has been a resurgence of interest in ontologies of late. These events have sparked my preparing this guide to ontologies. Overview and Role of Ontologies There is an M.C. A Spectrum of Formalisms.
