Recently proposed form-based web information systems liberate
the capture and reuse of data in organizations by
substituting the development of technical implementations
of electronic forms for the conceptual modelling of forms'
tree-structured schemas and their data access rules. Significantly,
these instance-dependent rules also imply a workflow
process associated to a form, eliminating the need for
a costly workflow design phase. Instead, the workflows thus
created in an ad hoc manner by unsophisticated end-users
can be automatically analyzed, and incorrect forms rejected.
This paper examines fundamental correctness properties
of workflows that are implied by instance-dependent access
rules. Specifically, we study the decidability of the form
completability property and the semi-soundness of a form's
workflow. These problems are affected by a choice of constraints
on the path language used to express access rules
and completion formulas, and on the depth of the form's
schema tree. Hence, we study these problems by examining
them in the context of several different fragments determined by such constraints.
