Greg Watson, IT Specialist, Defense Intelligence Agency Missile and Space Intelligence Center (apparently it IS rocket science). I installed eXist last night to follow along with the talk.<\/p>\n

“If you have a larger dataset, eXist may not be the best choice.” Recommended reading: XQuery<\/a> by Priscilla Walmsley, XQuery wikibook<\/a>.<\/p>\n

Download<\/a> and install. Needs a full JDK (Mac includes this already in \/Library\/Java\/Home), a mere JRE is insufficient. Start up with bin\/startup.sh.<\/p>\n

eXist-specific useful functions: request:get-parameter() from the URI query string. transform:transform() function invokes XSLT from within XQuery.<\/p>\n

Example uses doc() to fetch an external URL of RSS, check individual items with contains(). Every example is a fully-formed, click-on-a-link-to-run program.<\/p>\n

XQuery and PHP: reallly basic integration with simplexml_load_file($myXQueryURL).<\/p>\n

Loading scripts into eXist: He uses XML Spy. eXist has a Jaa Web Start admin client.<\/p>\n

Q&A: How bit is too big? Maybe 10-20-30 thousand docs. Generate indexes? Yes.<\/p>\n
