Online Ontology Visualisation: RDFa

octubre 5, 2010

jOWL status updateI packaged the latest development version of jOWL into a 0.5 release, available at Google Code. jOWL is an AJAX/javascript extension to jQuery that I am developing. The jOWL library parses and reasons with OWL-DL documents. Supported browsers for this release are Internet Explorer 7 and Firefox 2 & 3.This release is accompanied by several new and impressive demos in my humble opinion. These make use of the new functionalities that have been incorporated so far. Below are some important highlights.

Pop Up window Bookmarklet Enhancement

Opens a Pop Up window for EASY Posting!

Full description:

SPECIAL NOTE!!  Please Rename the Folder in this Zip file AFTER you have Backed Up your Original Bookmarks Folder in the /mod directory. The folder in this ZIP file once you put it in the /mod directory must be Re-named to: bookmarks I want to give thanks for an idea that started with Ping.FM and their Bookmarklet Pop Up Window code. Like all things create a BackUp of the original Elgg Bookmark Folder in the Mod directory if you ever want to go back to that one. Just Unzip the folder bookmarks_PopUp into your /mod directory and go into Admin to enable and turn on the plugin. Then you go back to your bookmarklet page and you need to re-install your bookmarklet to your browser tested works in Firefox and IE 8 and now you got a Pop Up Window! I am looking for someone to add to this create a Auto Close with a slight Delay like Facebook has or Digg.com and Scuttle. Please let me know if you can do this!

Planning a Semantic Web site

junio 30, 2009

Rob Crowther (robert@crowther.info), Web developer, Freelance

Summary: The Semantic Web brings with it the opportunities for users to get smarter search results, and for site owners to get more targeted traffic as users find what they really want. But these benefits don’t just magically appear. This article leads you through the aspects of both information architecture and general infrastructure you need in place to truly take advantage of this burgeoning opportunity.

This article discusses what you need to know to make your Web site part of the Semantic Web. It starts with a discussion of the problems the Semantic Web tries to solve and then moves to the technologies involved, such as Resource Description Framework (RDF), Web Ontology Language (OWL), and SPARQL Protocol and RDF Query Language (SPARQL). You’ll see how the Semantic Web is layered on top of the existing Web. It then covers some issues that you want to know about when you plan a new Web site and also gives specific examples of how to use technologies like RDFa and Microformats to enable your existing Web site to become a part of the Semantic Web.

Semantic Web Server – URIQA

About

The Nokia Semantic Web Server is an RDF based application suite for metadata-driven web publishing and knowledge management. It is a central component of the Forum Nokia website, the Nokia Research Center website, and the Nokia Open Source website. It also serves as Nokia’s reference implementation of URIQA, the URI Query Agent model.

The Nokia Semantic Web Server suite is comprised of a number of modular semantic web services:

/uriqa? – a URIQA query portal, with rule-based inference functionality.

/new? – a query portal for obtaining information about recently published or updated resources, provided as RSS 1.0 or as RDF Facets; also with rule-based inference functionality.

/id? – a resource identifier generator, employing UUIDs and providing PURL functionality.

/query? – a metadata and free-text query portal, providing output results as RSS 1.0 feeds; with both metadata driven and crawler based indexing agents.

/search? – a human friendly search UI; which integrates with any conformant /query? portal.

/editor? – a web form based, ontology driven metadata editor with validation and user authentication & access control; which integrates with any conformant /uriqa? portal.

The core of these web services are provided as open source, and while most can be used “out of the box”, some require a moderate amount of configuration and customization depending on the requirements and constraints of the particular solution.

License

The Nokia Semantic Web Server code is released under the NOKOS version 1.0a .
