> The graph commands in the SPI were an initial attempt to identify the set of functionality that the connectors should support.  One problem with the current design is that it's not really feasible or possible to track with each child the identification properties for the child.  For example, when getting the children of a node, it's not mandatory (nor that clear) that identification properties be recorded for each child as well.  It's very important to provide a way for all nodes (including children) to be fully identified.
> Plus, we know that we're missing some very useful (if not required) commands, like the ability to get a node given some (or all) of its identification properties, and the ability to get a single property (with all values) for a node.
> Also, consider something that will make it easier to use these commands, such as a DSL.
