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

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
The World Wide Database is a globally distributed network of data records that reside on millions of nodes around the network which collectively behaves as a giant virtual, decentralized database system...we need a new kind of server for hosting WWDB node
I've gotten hammered in the comments on my post about freebase for suggesting that the semantic web was only about controlled ontologies....What's going to be really interesting is to see how the Semantic Web technologies develop now that we have actual,
he Music Ontology Specification provides main concepts and properties fo describing music (i.e. artists, albums and tracks) on the Semantic Web. This document contains a detailed description of the Music Ontology.
Annotea is a W3C Semantic Web Advanced Development project that provides a framework for rich communication about Web pages through shared RDF metadata. An RDF model of bookmark classification permits multiple classification systems to be related to each
Identity is fundamental to ontology, and especially to information systems ontologies. Identity is well known in metaphysics and in database conceptual modeling. In the latter case, it is an accepted best practice to specify a primary key for rows in a ta
A great jump towards the advent of the Semantic Web will take place when a critical mass of web resources is available for use in a semantic way. This goal can be reached by the creation of semantic meta-data in the publication workflow, or by the develop
Category search within digital repositories is poorly supported. This means that people wishing to access the assets of digital repositories are largely limited to keyword search, which means they must know what they want in order to look for it. Our part
The introduction of semantics on the web will lead to a new generation of services based on content rather than on syntax. |:| Effective semantic search engines will provide means for successful searches avoiding the heavy burden experimented by users in
Automatic semantic annotation of information content is an open problem, but is crucial to the realization of the Semantic Web. Annotation systems require the initial definition of an ontology and as well as a knowledge base. Both of these resources work
We believe that the enterprise ontology will become a cornerstone in many information systems in the future. In general terms, an ontology is an organization of a body of knowledge or, at least, an organization of a set of terms related to a body of know
Part of the allure of classifying things by assigning tags to them is that the user can give free reign to sloppiness. There is no authority —human or computational— passing judgment on the appropriateness or validity of tags, because tags have to mak
The goal of this ontology is to model the relationship between an agent, an arbitrary resource, and one or more tags. This relationship is embodied in one or more taggings, which are temporal events associating the actors.
Ontologies play a prominent role on the Semantic Web. They make possible the widespread publication of machine understandable data, opening myriad opportunities for automated information processing. However, because of the Semantic Web's distributed natur
This post is part contribution to the general Web 3.0 / Data-Web / Semantic Web discourse, and part experiment / demonstration of the Data Web. I came across a pretty deep comments trail about the aforementioned items on Fred Wilson's blog (aptly title

Web Ontology Language (OWL) is a markup language for publishing and sharing data using ontologies on the Internet. OWL is a vocabulary extension of the Resource Description Framework (RDF) and is derived from the DAML+OIL Web Ontology Language (see also D
A Semantic Wiki is a Wiki enhanced with technologies developed by the Semantic Web community in order to encode more knowledge than just structured text and hyperlinks. Usually this extra knowledge is available in a formal language, so that machines can (
The emergence of P2P Inference Engines and domain-specific ontologies in Web 3.0 (aka Semantic Web) will present a major threat to the central “search” engine model. In Web 3.0 (aka Semantic Web) P2P Inference Engines running on millions of users’ P

Real life data needs are never semantically pure. Users need to browse their data in different ways. Hierarchies are too hard to reorganize on a whim. Stuff I need access to DOES NOT HAPPEN TO EQUAL the stuff at the top of the tree: Hierarchies are bad a
