Data necessary for operation of the system. These should be values that are immutable toward the user or system operator. Example: sane defaults for field labels.

Note: at present, these sort of default values for certain modules are only loaded when you specify LoadReferenceData=true on module initialization. This proposes we move those into an immutable category.

Overlay Data

Data that may be used to supersede System Data when a user or system operator wants to change something immutable Example: a default field label.

Can be used to override any System Data, as well as introducing new values.

NO

• uuid(integer,64)
• subtitle(NA)
• authors(string,256)

Sample Data/User Data

Data that can be used to demo the system or is useful for providing examples to users.

Data entered by users specific to an institution.

This data is not necessary for the operation of the system. Example: a user record for a fake (or real) patron.

This layer also holds sample data, since it's essentially real data for a fictional tenant.

NO

To load example data (like diku), introduce another switch (LoadExampleData=true)
