Universal Unique Identifiers (UUIDs) ensure the unique identification of components across all servers, databases, and studies.
In most cases, assignment of a UUID attribute is optional. However, for certain purposes, the InForm application requires the use of specific, well-known UUIDs. For example, to allow users to define subject numbers, rather than allowing the InForm application to generate them automatically, you must use well-known UUIDs for the formset, form, section, item, and text control definitions that make up the specification of the subject number data-entry field.
