2. A model is...
A BrainStorm model is a single file much like a text document or an image file. Its contents may include entries (notes, thoughts, text, etc.) on a wide range of subjects or on a very specific focused topic, as you wish.
It is a free-form collection of paragraphs (or sentences, or words) which may be linked in different ways according to your mood and the stage of development of your information. It can be a single list or a hierarchical structure.
In practical terms, a model is a collection of entries. Each entry can have any number of sub-entries, and they can have sub-entries, and so on, and so on. An entry can be up to 64,000 characters and can contain multiple paragraphs - useful for lines of a poem or a song, for example. Normally an entry would contain a line, a sentence or a paragraph. Your choice.
While this structure can be thought of as a list with underlying sub-lists, it can also represent any type of hierarchical structure. One example is a book where the structure is represented by chapters, subjects, topics, and paragraphs.
When working within BrainStorm, any number of models may be open simultaneously and entries can easily be moved between the open models. You can copy and paste or, more easily, use Magic paste to collect information from any on-screen display (web page, Word document, Acrobat document etc.) Magic paste automatically transfers text from the clipboard into BrainStorm, according to rules which you set.
Here are illustrations of three types of program which work with textual information. They show a key BrainStorm difference quite clearly:
A logical view of the information inside a word processor, an outline and a BrainStorm model
Each block represents a paragraph, idea, entry or note: depending on the terminology of the program.
