To provide some clarity about Virtuoso and Blogging I have decided to put out this quick step by guide to the workings of my blog (there is a long overdue technical white paper nearing completion that address this subject in more detail).</p>\n<p>Here goes:</p>\n<p><u><strong>Blog Editing</strong></u></p>\n<p>I can use any editor that supports the following Blog Post APIs:</p>\n<p>- Moveable Type</p>\n<p>- Meta Weblog</p>\n<p>- Blogger</p>\n<p>Typically I use Virtuoso (which has an unreleased&nbsp;WYSIWYG blog post editor), <a href="http://www.newzcrawler.com/">Newzcrawler</a>, <a href="http://ecto.kung-foo.tv/">ecto</a>, <a href="http://zempt.com/">Zempt</a>, or <a href="http://www.wbloggar.com/">w.bloggar</a> for my posts. If a post is of interest to me, or relevant to our company or customers&nbsp;I tend to perform one of the following tasks:</p>\n<p>- Generate a post using the "Blog This" feature of my blog editor</p>\n<p>-&nbsp;Write a new post that was triggered by a previously read post etc.</p>\n<p>Either way, the posts end up in our company wide blog server that is Virtuoso based (more about this below). The internal blog server automatically categorizes my blog posts, and automagically determines which posts to upstream to other public blogs that I author (e.g <a href="http://kidehen.typepad.com/">http://kidehen.typepad.com</a> ) or co-author (e.g <a href="http://www.openlinksw.com/weblogs/uda">http://www.openlinksw.com/weblogs/uda</a> and <a href="http://www.openlinksw.com/weblogs/virtuoso">http://www.openlinksw.com/weblogs/virtuoso</a> ). I write once and my posts are dispatched conditionally to multiple outlets.</p>\n<p><strong><u>RSS/Atom/RDF Aggregation &amp; Reading</u></strong></p>\n<p>I discover, subscribe to, and&nbsp;view blog feeds using <a href="http://www.newzcrawler.com/">Newzcrawler</a> (primarily), and from time to time for experimentation and evaluation purposes I use <a href="http://www.rssbandit.org/">RSS Bandit</a>,&nbsp;<a href="http://www.bradsoft.com/feeddemon/">FeedDemon</a>, and <a href="http://www.bloglines.com/">Bloglines</a>. I am in the process of moving this activity over to Virtuoso completely due to the large number of feeds that I consume on a daily basis (scalability is a bit of a problem with current aggregators).</p>\n<p><u><strong>Blog Publishing</strong></u></p>\n<p>When you visit my blog you are experiencing the&nbsp; soon to be released Virtuoso Blog Publishing engine first hand, which is how&nbsp;WebDAV, SQLX, XQuery/XPath, and Free Text etc. come into the mix.</p>\n<p>Each time I create a post internally, or subscribe to an external feed, the data ends up in Virtuoso's SQL Engine (this is how we handle some of the obvious scalability challenges associated with large subscription counts). This engine is SQL2000N based, which implies that it can transform SQL to XML on the fly using recent extensions to SQL in the form of SQLX (prior to the emergence of this standard we used the FOR XML SQL syntax extensions for the same result). It also has its own in-built XSLT processor (DB Engine&nbsp;resident), and validating XML parser (with support for XML Schema).&nbsp; Thus, my <a href="http://www.openlinksw.com/blog/~kidehen/gems/">RSS/RDF/Atom archives, FOAF, BlogRoll, OPML, and OCS</a> blog syndication gems are all live examples of SQLX documents that leverage Virtuoso's WebDAV engine for exposure to&nbsp;Blog Clients.</p>\n<p><strong><u>Blog Search</u></strong></p>\n<p>When you search for blog posts using the basic or <a href="http://www.openlinksw.com/blog/search.vspx?blogid=127">advanced search</a> features of my blog, you end up interacting with one of the following methods of querying data hosted in Virtuoso: Free Text Search, XPath, or XQuery. The <a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&q=virtuoso&type=text&output=html">result sets</a> produced by the search feature uses SQLX to produce subscription gems (<a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&q=virtuoso&type=text&output=xml">RSS</a>/<a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&q=virtuoso&type=text&output=atom">Atom</a>/<a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&q=virtuoso&type=text&output=rdf">RDF</a>/<a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&type=text&kwds=virtuoso&OpenSearch">OpenSearch</a>) and <a href="http://www.openlinksw.com/blog/search.vspx?blogid=127&q=virtuoso&type=text&output=html">URIs</a> that enable dynamic tracking of my posts using your search keywords.</p>\n<p>BTW - the <a href="http://www.openlinksw.com/blog/~kidehen">http://www.openlinksw.com/blog/~kidehen</a> blog home page exists as a result of Virtuoso's Virtual Domain / Multi-Homing Web Server functionality. The entire site resides in an Object Relational DBMS, and I can take my DB file across Windows, Solaris, Linux, Mac OS X, FreeBSD, AIX, HP-UX, IRIX, and SCO UnixWare without missing a single beat! All I have to do is instantiate my Virtuoso server and my weblog is live.</p>" ; "WebDAV, SQLX, and my Weblog" ; ; ; , , , , OpenSearch) and , , , , , , , , , , , , , , , , , ; ; ; "2005-04-26T03:54:43Z" ; "2006-06-22T12:56:58Z" ; . , ; ; "uda's BLOG [135] description" . . . ; . ; ; "UDA Data Space Bot" ; . , ; ; "uda's BLOG [135] description" ; ; ; . ; ; .
