The OBO Foundry is a collaborative experiment involving developers of science-based ontologies who are establishing a set of principles for ontology development with the goal of creating a suite of orthogonal interoperable reference ontologies in the biomedical domain. The groups developing ontologies who have expressed an interest in this goal are listed below, followed by other relevant efforts in this domain.
In addition to a listing of OBO ontologies, this site also provides a statement of the OBO Foundry principles, discussion fora, technical infrastructure, and other services to facilitate ontology development.
A metamodel is a precise definition of the constructs and rules needed for creating semantic models...an attempt at describing the world around us for a particular purpose.
In an attempt to summarize the relationship among various metadata formats and how they relate to building Internet systems I wrote a glossary. I then ordered and tied the terms together with a bit of narrative to explain the relationships among the terms

"...the conception of the Avant Garde is discarded as a general movement forward toward a utopian external and is reoriented to a general movement inward..." from "Avant Garde?" as seen in the Post-Dogmatist Quarterly
The Suggested Upper Merged Ontology (SUMO) and its domain ontologies form the largest formal public ontology in existence today. They are being used for research and applications in search, linguistics and reasoning. SUMO is the only formal ontology that
"Swoogle is a search engine for the Semantic Web on the Web. Swoogle crawl the World Wide Web for a special class of web documents called Semantic Web documents, which are written in RDF."
Discussion of flaws and potential solutions to using social bookmarking sites (from del.icio.us to digg) as folks monetize, abuse, trick, and tweak them: no uniform tagging conventions, flat tag structures (non-relational), overly-generalized tags (catego
OntoSelect monitors the web to provide an access point for ontologies on any possible topic or domain that is automatically updated, organized in a meaningful way and with support for ontology search and selection. Selected ontologies may be used for ins
Vocabularies for every academic, business, professional field, plus taxonomies for "Asian Vegetables," "General Knowledge," "Forbidden Drugs," and "Leadership."
Unlike vanilla XML, RDF vocabularies can be freely mixed together in data without prior agreement. So you often see ad-hoc combinations of Dublin Core, RSS1, MusicBrainz, RDF-calendar, FOAF, Wordnet, thesaurus, Geo-info etc etc frequently deployed togethe
Source vs. Resource Ontology The notion of a resource is fundamental in current networked information systems. The term "resource" is used often, specifically in relation the World Wide Web and the W3C's semantic web activity, in standards such as Resour
This piece speaks about the different parts of the Semantic Web and how they fit together. For a high-level interview, take a look at Sandro Hawke's The Semantic Web (Put Simply). On the other hand, if you're a Web developer who's interested in building S
Semantic similarity, also called semantic relatedness or semantic closeness/proximity/nearness, is a concept whereby a set of documents or terms within term lists are assigned a metric based on the likeness of their meaning / semantic content.
The Metaweb technology that supports Freebase is indeed centralized, but only for computational speed. Distributing queries of real-world complexity over a high-latency network is a very difficult problem...[Freebase will] allow wiki-style editing of the
