Nov 4 2009: Getting active, or maybe reactivating.

This page is just a collection of links so far. The link above for the 'Miscellaneous' subject is to my own modest effort with Semantic Mediawiki. It's nascent but coming along.

The entire Semantic Web subject area will be getting a makeover soon.

Jan 26 2009. derived from PHP Wikis and Knowledge Wikis.

Often referred to as "knowledge wikis", they are capable of providing some level of knowledge representation and management functions as well as the usual features available in traditional wikis. They may be the closest existing solution to some of the requirements for a Semantic Web ( however it gets defined ).

Revised Nov 1 2008: Draft of OWL2 specs.

The recent drafts of the OWL2 specification describe some important changes from OWL1. In a nutshell,

The structural specification of OWL 2 provides the foundation for the implementation of OWL 2 tools such as APIs and reasoners. ... This document also defines the functional-style syntax, which closely follows the structural specification and allows OWL 2 ontologies to be written in a compact form.

Link - WordNet

Not sure if WordNet qualifies as the "Semantic Web", but it's definitely semantic whatever the format may be. From the site ( paraprased )

WordNet® is a lexical database containing nouns, verbs, adjectives and adverbs. They aregrouped into "synsets" ( sets of cognitive synonyms ) each expressing a distinct concept. Conceptual-semantic and lexical relations build links between synsets. A browser navigates through the network of meaningfully related words and concepts.

Updated Sept 16 2008

Semantic web search engines ? Social bookmarking run mad ? We shall see. The new search technology is still early in the S-curve and more useful for pop culture subjects than for rule based systems.

From the WikiaSearch project page:

Wikia's search engine concept is that of trusted user feedback from a community of users acting together in an open, transparent, public way.

It's getting serious. Things are moving resolutely forward toward Drupal 6 and 7.

The seems to be some confusion about the difference between 'rule engines' and 'semantic web' applications. See related link to "Semantic Web Inferencing versus Rule Engines"

Opera has several browser plugins and lively projects to build support for the Semantic Web.

One of most interesting plugins is the Tabulator RDF Browser Plugin. It's one of the few RDF tools that actually works.
