Resource Repository

The resource repository enables users to access local copies of files that may originally have resided at a remote location. The resources are keyed by their original public ID and/or system ID. If a caller the resource repository requests a resource that is not held locally, the resource repository attempts to download it from the URI provided as a system ID, and if successful caches the content locally. The resource repository can also act as an entity resolver.

Resource

The resources are stored locally and made accessible on demand as a


    java.io.InputStream

Resource Meta-data

Resource meta-data are used to register a resource. The basic resource repository implementation that comes with OBE stores these data in the configuration file BasicResourceRepository.xml; the entries have the format:

<entry>
    <resource id="nmtoken" type="nmtoken" threadsafe="true|false"?>
        <display-name .../>?
        <author .../>?
        <description .../>?
        <doc-url .../>?
        <public-id .../>
        <system-id .../>
    </resource>
    <instance xsi:type="java:fqcn" ... />
</entry>

public-id: The Public ID of the resource (required for DTD resolution, etc.).
system-id: The System ID of the resource.
instance: The name of the disk file containing the resource content, relative to ${obe.config.dir}/resources.
