With the introduction of family records, the name data/AllData is no longer appropriate, since the page only displays available patients.
Ideally, once we upgrade to a version of XWiki that supports nested spaces, the structure would be:
data/ - for the dashboard
data/Patients/ - for all patients
data/Patients/P1234567 - for individual patient records
data/Families/ - for all families
data/Families/FAM1234567 - for family records
