Allows a user to search for existing forms

Allows retrieval of a specific known form

Allows retrieval of a specific version of a form

Allows review of changes to a form over time

Allows defining a new form. Repositories requiring curation of submitted forms may require all new data elements to have a status of 'draft'.

Allows an existing form to be updated. Servers may choose to prohibit certain types of edits, instead requiring the creation of a new questionnaire (and potentially the retiring of the existing questionnaire). Servers may also limit who can change particular forms.

Allows removal of an existing form. Servers may choose to not support deletions and instead require that the form's status be changed to 'retired'. Other systems support deletions but limit them to forms meeting certain requirements. E.g. only forms with a status of draft or only forms that have been retired for at least two years, etc.

Allows discovery of existing code systems for use in authoring questionnaires

Allows retrieval of a specific code system referenced within a questionnaire

Allows retrieval of a historical version of a code system as referenced within a questionnaire

Allows review of changes to a code system over time

Allows definition of a new code system used by one or more questionnaires

Allows existing code systems referenced by one or more questionnaires to be maintained

Not all servers will support deletion of code systems. Status change to 'retired' will be more typical, though deletion of draft code systems may keep repositories cleaner.

Allows discovery of existing value sets for use in authoring questionnaires

Allows retrieval of a specific value set referenced within a questionnaire

Allows retrieval of a historical version of a value set as referenced within a questionnaire

Allows review of changes to a value set over time

Allows definition of a new value set used by one or more questionnaires

Allows existing value sets referenced by one or more questionnaires to be maintained

Not all servers will support deletion of value sets. Status change to 'retired' will be more typical, though deletion of draft value sets may keep repositories cleaner.
