The CRPA application helps you create and benefit from your Constructive Recollection, which can be any project you develop, research, scenario, study or story. Basically, you work with entities and relations. Entities are called "Notes" and these are collected in "Sheets".
Sheets are used to collect your Notes, and how one Relates to another, logically or temporally;
Notes are used on Sheets to visualize them ('yellow sticky notes') and relate them; they contain everything there is to know about them as things you wish to single out, document, visualize, aggregate or attach to external files;
Attachments may be used as separate shortcuts from Notes to external files.
It is not necessary that your project tree contains Sheets, that your Sheets contain Notes, or your Notes contain Attachments. However, they should contain these when you need them and that is what you create them for, basically. You must have a Sheet to create Relations between Notes, however.
Below is an example project tree called "Structure of CRPA.CRP". This was also the name, used to save the work done in a CRPA session.
When the Notes have Relations or links, these will appear automatically on the Sheet, visibly linking the Notes.
Different Sheets have different Note recollections that form different networks or mind maps. If a Note on one Sheet is the same as a Note on another Sheet, it can (as a 'linking pin') relate the different networks into one. Then all Notes and all links combined, are visible in one overview.
The headers of the Notes in the Sheet window show in angle brackets <..> how many Relations or links they each have, from and to other Notes. They may have been used in other Sheet windows where they acquired some or all of their Relations. You can see in the above picture that the numbers of these Notes increased, after the Sheet windows were integrated.
When the configuration of Notes and Relations changes, different Sheets can:
1. show the change from different moments or perspectives, and
2. integrate into one Sheet.
Notes act as 'linking pins' between Sheets and Sheet windows, no matter how many Sheets or Notes you have or how far apart they are in the project tree. Once you create a Relation between Notes, it will always connect the same Notes on every Sheet window you create or open from any perspective, until you change or delete it or one of the related Notes.
