Example Setup scripts. Oracle XML DB - Supplied XML Schemas

This appendix describes a few example setup scripts for use with the examples in Chapter 3, "Using Oracle XML DB". It also includes the structure of Resource View and Path View and the Oracle XML DB supplied XML schema:

• Example Setup Scripts
• RESOURCE_VIEW and PATH_VIEW Database and XML Schema
• XDBResource.xsd: XML Schema for Representing Oracle XML DB Resources
• acl.xsd: XML Schema for Representing Oracle XML DB ACLs
• xdbconfig.xsd: XML Schema for Configuring Oracle XML DB

Example Setup Scripts

The following sections include the setup scripts and sample files used for the examples in Chapter 3, "Using Oracle XML DB".

RESOURCE_VIEW and PATH_VIEW Database and XML Schema

The following describes the RESOURCE_VIEW and PATH_VIEW structures.

Resource View Definition and Structure

The RESOURCE_VIEW contains one row for each resource in the Repository. The following describes its structure:

Column      Datatype     Description 
------      --------     -------------------------------------------------------
RES         XMLTYPE      A resource in Oracle XML Repository 
ANY_PATH    VARCHAR2     A path that can be used to access the resource in the
                         Repository 

PATH_VIW Definition and Structure

The PATH_VIEW contains one row for each unique path in the Repository. The following describes its structure:

Column      Datatype     Description 
------      --------     -----------------------------
PATH        VARCHAR2     Path name of a resource 
RES         XMLTYPE      The resource referred by PATH 
LINK        XMLTYPE      Link property
