No abstract provided.
The XFDL compute engine implements a 'declarative' computation system. The behavior of the algorithm is similar to that of a spreadsheet. Complicating factors for XFDL include dynamic references and side effect functions such as
. When a form is first started, many nodes with computed values may need to be evaluated to find current display values. After the form is started, any specific change to a given node should result in updates to computationally dependent nodes. Further, the process is recursive in that when a computationally dependent node is updated, then it may have further computationally dependent nodes that must be queued for update.
The XFDL specification provides an abstract version of the desired algorithm, but does not place specific constraints on the data structure used to represent the compute system.
