| − | Welcome to the Query Portal, which is one of the [[Main Page|Main Sections]] of this documentation. BaseX provides an implementation of the W3 [http://www.w3.org/TR/xpath-30/ XPath] and [http://www.w3.org/TR/xquery-30 XQuery] languages, which are tightly coupled with the underlying database store. High conformance with the official specifications is one of our main objectives, as the results of the [http://dev.w3.org/2006/xquery-test-suite/PublicPagesStagingArea/XQTSReportSimple_XQTS_1_0_2.html XQuery Test Suite] demonstrate. This section contains general information on the query processor and its numerous extensions.
