Subject:AW: [sdo] SDO-55 - Create an EntityResolver like concept for resolving imported/included schemas

Hi Blaise,

I have a question about the "parentXSD" parameter. The javaDoc says it is the
XSD doing the import, but I think you mean the (absolute) URI of the schema (so
that relative locations can be resolved). Is this correct?

Hello All,

Attached are the proposed source changes. I have renamed SchemaResolver to
SchemaInputResolver as we may want to have a SchemaOutputResolver as well. Of
course we could have a SchemaResolver that does both input & output, thoughts?

As discussed last week, most SDO implementations have some means of resolving
System URIs. There a couple of use cases for which this is useful:

* The user is loading there XML schema using a non-standard URI (i.e.
pointing to somewhere on there class path). * The user is specifying imported/included XML schemas using a relative path. In the EclipseLink SDO implementation we have introduced the concept of a
SchemaResolver. This interface has the following signature:

public interface SchemaResolver {

/** * @param parentXSD - The XSD doing the import or included (null for root
schemas), the system id can be obtained to resolve relative URIs * @param namespace - The namespace portion of the import/include * @param systemID - The URI representing the location of the XML schema. */ public javax.xml.transform.Source resolveSchema(javax.xml.transform.Source
parentXSD, String namespace, String systemID);

}

Java SE also has the concept of an LSResourceResolver
(http://java.sun.com/javase/6/docs/api/org/w3c/dom/ls/LSResourceResolver.html).
This approach has the benefit of working well with the javax.xml.validation
APIs.

Hopefully we can get some discussion on this topic, in order to come up with a
solution that works for everyone.
