HTML microdata [MICRODATA] is an extension to HTML used to embed machine-readable data into HTML documents. Whereas the microdata specification describes a means of markup, the output format is JSON. This specification describes processing rules that may be used to extract RDF [RDF11-CONCEPTS] from an HTML document containing microdata.
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
INCLUDE: Use this for the filter to be applied to any include targets matching a specified servlet name or with URLs matching a specified pattern.
FORWARD: Use this for the filter to be applied to any forward targets matching a specified servlet name or with URLs matching a specified pattern.
REQUEST: Use this in addition to an INCLUDE or FORWARD setting (one <dispatcher> element for each setting) for the filter to also be applied to direct request targets matching a specified servlet name or with URLs matching a specified pattern. (It is nonsensical to use the REQUEST value only. If you want the filter to apply only to direct requests, there is no need to use the <dispatcher> element.)
ERROR: Use this for the filter to be applied under the error page mechanism.

In July 2008 Thomson Reuters added a new "citation mapping" tool to its Web of Science product. This tool, which is touted on the Web of Science (hereafter, WOS) search interface as a beta version, enables users to visualize the relationship between citing and cited references. The citation mapping tool is a welcome addition to WOS. Below I discuss how the tool works, offer some comments and suggestions about it, and conclude with some notes about future directions.
Persons interested in bibliographic visualization software may also find of interest HistCite, developed by Eugene Garfield, pioneer of cited/citing searching and analysis. For an overview of HistCite, see Herther (2007). This review will not compare the new citation mapping tool in WOS to the features of HistCite, but will reference the HistCite web page in a few places.
Once you’re through with this article, there’s a followup that shows how to also make them clickable. Many people find the object-oriented aspect of JavaScript to be very confusing. Fortunately, the designers of the Google Maps API have managed to ma
A web-based mapping application that actually provides more than just simple mapping capabilities...it's surprisingly polished and well-behaved...he best of the three web-based mind mapping applications I've seen so far.
I posted an updated tech demo of RhNav - Rhizome Navigation visualizing user behavior of this blog. The graph is now centered around the page where most time is spent. Noise created by search engine robots is filtered which should clear things up quite a
Using RhNav - Rhizome Navigation I wrote a data aggregator for Technorati's API. The first result is a video which visualizes blog domains by analysing Technorati's Cosmos (the blogs which link to a particular URL). The video is a screencast of RhNav fetc
