Querying OSLC Resources

Once an OSLC client is obtained, you can query and update OSLC resources by executing requests.

MDAccess for OSLC provides generic requests to query and update OSLC resources:

• GetResource: loads the content of an OSLC resource.
• PutResource: updates the content of an OSLC resource.
• PostResource: usually used to create a new OSLC resource.
• DeleteResource: deletes an OSLC resource.

MDAccess for OSLC also provides ready to use requests for the most common tasks involved when communicating with an OSLC application:

• GetRootServices: entry point to obtain information on the OSLC application, notably the OAuth settings and reference to the service provider catalog(s).
• GetServiceProviderCatalog: loads a catalog of service providers, to obtain the list of available projects.
• GetServiceProvider: loads the details of one service provider.

Below is a sample code listing Requirement Management projects in an OSLC application:

	System.out.println("Reading Root Services...");
	RootServices rootServices = new GetRootServices<RootServices>(URI.create("https://myserver/rootservices"), RootServices.class).call();
	
	URI catalogLocation = (URI) rootServices.getExtendedProperties().get(
		new QName("http://open-services.net/xmlns/rm/1.0/", "rmServiceProviders"));
	
	System.out.println("Reading Catalog...");
	ServiceProviderCatalog catalog = new GetServiceProviderCatalog(client, catalogLocation).get();
	System.out.println("Catalog has " + catalog.getServiceProviders().length + " projects:");
	for (ServiceProvider provider : catalog.getServiceProviders()) {
	    System.out.println(" - " + provider.getTitle() + ": " + provider.getAbout());
	}
