Querying OSLC Resources
Selecting OSLC Configurations
MDAccess for OSLC supports configuration management. It provides facilities to present available configurations in a user interface and allows a user selecting one of them.
To query or update an OSLC resource in a specific configuration, you just need to add an oslc_config.context query parameter on the resource URI to reference the desired configuration.
Querying a non-versioned OSLC resource:
URI resourceUri = URI.create("https://myServer/myResource");
Object resource = new GetResource(client, resourceUri).get();
Querying a versioned OSLC resource in a specific configuration:
URI versionResourceUri = URI.create("https://myServer/myResource?oslc_config.context=https://myServer/myConfiguration");
Object versionedResource = new GetResource(client, versionResourceUri).get();
MDAccess for OSLC provides a helper method to obtain a versioned resource URI, which you are recommended to use:
URI configurationUri = URI.create("https://myServer/myConfiguration");
URI resourceUri = URI.create("https://myServer/myResource");
URI versionResourceUri = OslcConfig.addContext(resourceUri, configurationUri);
Object versionedResource = new GetResource(client, versionResourceUri).get();
