Abstract: In a process of developing software applications from software components, the validity of component interactions is automatically validated by a program that determines a permission statement for any given utilization of a server component (305) by a client component (307). In a predefined structure (211–272), descriptors (211–219) are assigned (231–239) to components (301–309), descriptors (220–225) are assigned (241–255) to descriptors (211–224), some descriptors (223) have declarations to components (305), and some descriptors (217) have declarations to descriptors (223). The permission statement is true when 4 predefined conditions are all in compliance. The conditions are defined in relation to a common descriptor (225), to client (217) and server (223) intermediate descriptors, and to first (261) and second (262) declarations.

Abstract: Some implementations provide a resource planning system for receiving a first scheduling request for a resource's time. This first scheduling request may include a date range and the estimated amount of time needed from the resource, but does not necessarily include concrete date and time facts. This first scheduling request may be refined by a second scheduling request, which specifies concrete date and time facts to schedule a portion of the resource's time that was originally requested by the first scheduling request.
