Appendix: The Application layer: Actions to be taken as a result of the user interface activity

The application section is made up of the Memento app itself and then, optionally, actions to be taken as specified by scripting by the user, as described here.

Appendix: The Data layer: Database & library structure

Libraries can be linked so they can work together as a database. So, each library has a structure of fields & other things (see below for what make up its structure), and each database has a structure of libraries & links between them (see About:Database structure#Examples for an example).
