With limada::concept you can draw, edit and store concept maps. A concept map is a diagram showing the relationships among concepts. They are graphical tools for organizing and representing knowledge. They include concepts, usually enclosed in circles or boxes of some type, and relationships between concepts indicated by a connecting line linking two concepts.

Concepts can be connected with labeled arrows. The relationship between concepts can be articulated in linking phrases, e.g., "gives rise to", "results in", "is required by," or "contributes to".

Concept maps are similar to mind maps, but give more freedom, as mind maps are often restricted to radial hierarchies and tree structures.

Every mark of a link is choosable in the marker-dropdown. You can select a link and choose a mark in the marker-dropdown to mark a link.

Storing contents (html, rtf, images) in your concept map

By dragging html, rtf or images on the surface, a concept with content is created. You see the content in the left area of the application. This content is stored in the database.

Organizing concept maps in Sheets

By default, the screen is splitted in two areas: one with your current concept map, the other to view contents of a concept.

You can change this to have two concept maps side by side by clicking on the sheet view-button in the toolbar.

You have now two views on your concept database. By dragging between the two views, you can create a sheet with all the concepts you want to have in one view.

If you want to hide, press Del to remove a concept out of the sheet (NOT out of the database!).

Save a sheet by clicking on the save sheet button in the tool bar. Please note: Sheets are NOT saved automatically if the are changed! You have to do this by your own,

Sheets are stored like other concepts in the database. You can act with them as any other concept – linking, moving etc.

You can choose a different shape with the shape-dropdown for your concept.
