Schema Document Properties

Target Namespace None
Version 0.20
Element and Attribute Namespaces
  • Global element and attribute declarations belong to this schema's target namespace.
  • By default, local element declarations have no namespace.
  • By default, local attribute declarations have no namespace.
Schema Composition
  • This schema imports schema(s) from the following namespace(s):
    • http://www.semwebtech.org/eca/2006/eca-ml (at ecaml.xsd)
    • http://rewerse.net/I5/NS/2006/r3# (at r3.xsd)
    • http://www.semwebtech.org/lang/2006/logic (at logic.xsd)
    • http://www.w3.org/1999/02/22-rdf-syntax-ns# (at rdf.xsd)
Documentation r3 provides and supports this XML Schema for compatibility with the ECA Framework (by translation between ECA-ML and r3).
All the elements here included translate into elements of the r3 namespace and are limited versions of the ones supported by the ECA Framework .
Currently, elements that do not belong to the eca or r3 namespaces are not supported outside of a response or of an eca : opaque (viz. any eca : Expression is ignored and may cause an error; unless it is an eca : opaque or an r3 : Expression ).
Beware that none of the ECA Framework namespaces (viz. logic and eca) is slash (/) or hash (#) terminated.

Element: response

Name response
Type Locally-defined complex type
Nillable no
Abstract no
Documentation This element is returned as a response to a request, viz.: register , deregister , request .
It is a translation of the appropriate response to the associated request: r3 : Loaded or r3 : Installed , r3 : Terminated , r3 : EvaluateResponse .
Errors processing a request may be signalled using an appropriate HTTP status (e.g. 500), in which case the body of the HTTP response is not expected to be a <response>.
The <response> is usually returned synchrounously with the POST request, but it may also be used to asynchronously POST additional responses in case of a <request> that includes a <reply-to>.
