XMLDB Data Resource Accessor

Overview

The XMLDB data resource accessor allows data service resources to expose a single XMLDB-enabled relational database.

Resource Properties

The XMLDB data resource accessor provides the following properties for any data service resource which uses it:

• {http://ogsadai.org.uk/namespaces/2005/10/properties}productInfo - information on the database, including name, vendor and version.
• {http://ogsadai.org.uk/namespaces/2005/10/properties}collectionSchema - database collection schema.

In addition to these the service deployer may provide application-specific metadata properties in the data resource accessor configuration files (see below).

Class

This data resource accessor is implemented by the following Java class:

uk.org.ogsadai.dataresource.XMLDBDataResourceAccessor

Interfaces

This data resource accessor implements the following interfaces:

• uk.org.ogsadai.dataresource.XMLDBCollectionProvider

Configuration

Any data service resource using an XMLDB data resource accessor uses the following configuration files:

• A data resource configuration file which specifies information about the database managed by the data resource accessor. This includes the connection URL, the driver class name and database meta data.
• A role map file which maps client credentials to database usernames and passwords and provides a means of authorising database accesses.

These files are constructed automatically by the tools we provide to deploy data service resources. However, if you are interested, a detailed description of these files can be found on this page.
