Hi,everyone,
I have a problem when i want to construct a composite process using
"repeat-While" or "repeat-Until". i aim to build a loop structure,
which is like this(write in program language, such as java), see following.
ClassA aa = new ClassA();
string [] return1 = aa.runProcess1();
// execute process1 and get the output, which here is a string set.
boolean condition = true;
while{condition == true} {
string return2 = aa.runSelectProcess(return1);
/* run selectProcess, select a string from the string set "return1",
* and selected string "return2" will be deleted from the string set "return1",
* the updated return1 will be used as input for selectProcess in next loop step. */
string return3 = aa.runProcess2(return2);
if ( return3.equals("OK") ){
condition = false;
// if return3 is equals "OK" , then the loop is end.
}
}
I don't know how to express the dataBinding among "Process1",
"selectProcess" and "Process2" in OWL-S. In this loop, Process1 's output
(return1) is binded to selectProcess 's input, and after selectProcess is
executed, and return1 is updated, which will be used as input for
selectProcess in next loop. if the update return1 can be expressed in
"hasEffect" in selectProcess?
may be it will use new class "loc" and "locBinding" in OWL-S 1.2 version or
something else, but i don't know how to use it exactly. can someone show me
an example.
I also don't know how to get result from a loop structure, such as "repeat-While" and "repeat-Until". Does the "outputBinding" in "hasResult" only binded
to the final output of the process in the loop structure when the loop is end?
any hint will be very helpful, thanks.
linyu.
