XQuery
– an XML Query Language
– SQL of the XML world
– integrates XML data from a variety of sources
– focus on data, not dbs; higher level than SQL
– does not include fulltext searching or update
– not a full-fledged programming language
– currently working through Lucene; SOLR very enticing
XQuery is a functional language built entirely on expressions
uses native XML types and XPath
can be “loosely typed”, e.g. can omit declaration of data types
– Elsevier has done some work on code conventions
let 10,000 FLWORs bloom!
primarily an image-based site
some search, but mostly browsing
