Dichotomous key

Each project can have one dichotomous key. That key consists of a theoretically unlimited number of steps. Each step consists of a number, a title and a description, plus one or more choices. Each choice consists of a title and a text and/or an image. Also, each choice has a target: the connection to the next element within the key. The target can either be another step, or a taxon.
You have the option to use images instead of text and therefore to build keys based on visual identification.
You can edit the key from the startpoint, following its structure as the users will see it. Additionally, you can create sections of your key that are not yet connected to the main key. In that way, several people can work on different parts of the key at the same time. Once finished, a section can be hooked up to the main key by simply choosing the sections starting step as the target of a choice already part of the main key.
While navigating through your key or key sections, a keypath is maintained at the top of the screen, just beneath the navigational breadcrumb trail. You can navigate within your key by clicking elements in the keypath. As the keypath can become quite large, only the last few elements are shown. To see the complete keypath, click the ∇ symbol at its very beginning.

Key sections

On this page you can jump tot the different key sections in the project. Key sections are parts of the key that are not connected to the main key. In that way, several people can work on different parts of the key at the same time. Once finished, a section can be hooked up to the main key by simply choosing the sections starting step as the target of a choice already part of the main key.
You can click an available section to edit. When you click "set as key start" the section in question will become the main key from where you can hook up other key sections.
You also can start a new key section by clicking "Start a new subsection". Note that a new key section is automatically added, regardless if you click "save" or not.

Key map

On this page you find a graphic representation of the main key. Click a node to see the steps that follow from it. Click and drag to move the entire tree.

On this page you can clean up orphaned choices and ghostly targets of your key. Clicking "clean up" will perform the following actions:
- delete choices that belong to a non-existing step
- delete choices that have no text, image or target
- eset non-existent target steps
- reset non-existent target taxa

Taxa not part of the key

This page shows a list of taxa that are not yet part of your key.

Key validation

This page shows a list of irregularities in your key:
- Steps without any choices. To edit, click the name the step.
- Steps with only one choice. To edit, click the name the step.
- Unconnected choices.

Taxon ranks in key

On this page you can define taxa of what rank or ranks will be part of your key.
The taxa that are of a rank below the red line in the list below are available in your key. To change the selection, move the red line up or down by clicking the ↑ and ↓ arrows. To include all ranks, move the line to the top of the list, above the first rank. As at least one rank is required to be included, the line cannot be moved below the lowest rank. When you are satisfied with your selection, click the save-button.
Please note that changing this setting will not detach any taxa that have already been attached to an end-point of your key. Taxa that have a rank that is no longer part of the selection below will remain connected to the key, until you manually detach them.

Store key tree

On this page you can have the system store a tree-structured representation of the key, required for runtime purposes. Click "store key tree" to perform this action.
Please note that, depending on the size of your key, this might take a few minutes.
