we created what we called dfvariables - dataflow variables as parameters. included in them are the normal things you would want, a default value, a type, a direction (in/out/inout), etc. but we also put in a way of doing dataflow - namely a source node and source variable (we support superstate hierarchy as well) - to let you get your data from another node. the value is stored in the context and for large files we provide datatypes such as asciifile and binaryfile.
if you are interested in more info/schemas/whatever let me know.
