Hi,
I think I have an interesting picture for this topic.
1) The data transformation capabilities for various databindings can be
nicely modeled as a weighted, directed graph with the following rules.
(Illustrated in the attached diagram).
* Each databinding is mapped to a vertex.
* If databinding A can be transformed to databinding B, then an edge will
be added from vertex A to vertex B.
* The weight of the edge is the cost of the transformation from the source
to the sink.
2) In the data mediator/interceptor on the wire, if we find out that the
data needs to be transformed from databinding A to databinding E. Then we
can apply Dijkstra's Shortest Path Algorithm to the graph and figure the
most performed path. It can be A-->E, or A-->C-->E depending on the weights.
If no path can be found, then the data cannot be mediated.
Any thoughts?
Thanks,
Raymond
