Figure 1 shows the Java packages distributed over a diagram with a layered URC and a layered Target. All package names are abbreviated (prefix "edu.wisc.trace." omitted).

The URC (on the left) consists of the following layers (from top to bottom):

• UI layer, with package urcsdk.client.pret
• URC framework core layer, with packages urcsdk.client.facade, urcsdk.client, urcsdk.client.resources, urcsdk.client.uisocket, urcsdk.client.uisocket.types and urcsdk.xpath
• Networking platform specific layer, with packages urcsdk.client.upnp2s and urcsdk.client.upnpdcps

The Target (on the right) consists of the following layers (from top to bottom):

• Application-specific layer (no packages contained)
• URC framework core layer, with packages urcsdk.target, urcsdk.target.facade and urcsdk.target.uisocket
• Networking platform specific layer, with package urcsdk.target.upnp2s

In the center of the diagram, between the URC and the Target, two packages are displayed that belong to the URC and Target:

• urcsdk.support, urcsdk.base and urcsdk.base.*.
