This XQuery Module contains helper functions for the RESTXQ API, some of which are defined in the RESTXQ Draft.


  • The module will be available if the basex-api library is found in the classpath. This is the case if you use one of the complete distributions of BaseX (zip, exe, war).
  • All functions are assigned to the namespace, which is statically bound to the rest prefix.
  • The namespace is bound to the wadl prefix.
  • If any of the functions is called outside the servlet context, basex:http is raised.

General Functions


Signatures rest:base-uri() as xs:anyURI
Summary Returns the implementation-defined base URI of the resource function.


Signatures rest:uri() as xs:anyURI
Summary Returns the complete URI that addresses the Resource Function. This is the result of rest:base-uri appended with the path from the path annotation of the resource function.


Signatures rest:wadl() as element(wadl:application)
Summary Returns a WADL description of all available REST services.


Updated with Version 9.4: Argument added.

Signatures rest:init() as empty-sequence()
rest:init($update as xs:boolean)() as empty-sequence()
Summary Initializes the RESTXQ module cache:
  • By default, the cache will be discarded, and all modules will be parsed and cached again.
  • If $update is enabled, the background caching behavior is simulated (see PARSERESTXQ): Only updated modules will be parsed.
  • This function should be called if new RESTXQ code is deployed at runtime.
