[jira] Commented: (WODEN-14) Use XML Catalog To Improve Performance and Enable Offline Work

    [ http://issues.apache.org/jira/browse/WODEN-14?page=comments#action_12426262 ] 
            
Graham Turrell commented on WODEN-14:
-------------------------------------

The framework to be implemented will be a simplified version of the XMLEntityResolver found in Xerces. The Xerces framework can resolve any deemed "XML Entity". For our purposes we are interested in resolving just URIs. If anyone believes the scope of the framework should be wider than URI/URL resolution then now is a good time to say! This JIRA however is URI specific.

The framework will have the full extensibility capabilities of the Xerces resolver model: any resolver mechanism (that conforms to the API) may be plugged in to woden as its resolver. I intend to supply and bundle a default SimpleResolver. Provision will be made for OASIS XML Catalogs to be plugged in as the resolving mechanism, specifically that within the XML Commons Resolver 1.1 (resolver.jar), and wrapper classes provided as an API (as it is with Xerces).

Further comments very welcome!

> Woden currently retrieves XML schemas from the Internet each time it performs a validator. This causes a multisecond performance degradation and prevents validation from working when there is no Internet access.
> Woden should use an XML catalog to resolve references to Internet resources. There should be an API for controlling the XML catalog so that Woden can be imbedded in other systems, such as Eclipse and Ant, that provide XML catalogs.
> The XML catalog should be consulted when resolving all resource requests, e.g. for XML schema or WSDL.
