Distributed execution model for cross-organizational declarative web applications

A computer readable medium comprising a computer readable program for distributed computation, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:

• providing a first service of a first computation node in a network of nodes, the first service having a first resource, the first resource including one of references to data and other resources;
• in a second service on a second computation node, referencing the first resource by associating the first resource in the second service for use in the second service;
• and
• performing a distributed computation across node boundaries using the references of the first resource to perform the computation in the first service and in the second service.
