|
|
---++++2.4.1 Traditional dichotomous keys.
|
|
|
|
Dichotomous keys (Box 2.3.1) are specialised identification tools comprising fragments of descriptive data arranged in couplets forming a branching tree. Each fragment (lead) comprises a small (occasionally verbose) natural-language description. Each node in the tree typically has two branches (dichotomy) but may have three (trichotomy) or more branches. Several differing formats of dichotomous keys are traditionally used.

---+++2.4.2 SDD representation of dichotomous keys
|
|
|
|
While dichotomous keys can be presented in various formats, the essential elements of all dichotomous keys are identical. Each consists of a tree of questions, each with two (or occasionally more) possible choices, each choice leading to another question or a taxon.
|
|
|
|
A dichotomous key rendered in SDD requires three essential items: the names of the taxa being described, a set of questions (leads) used to separate the taxa, and the nodes defining the structure of the leads.
|
|
|
|
A simple SDD instance document for dichotomous key data has the basic structure shown below and in Example 2.4.2.
|
|
|
|
There are at least two different ways of generating a dichotomous key in a well structured SDD instance document, using statements or questions, these will be dealt with separately.

|
|
|
When a dichotomous key in an SDD instance document is structured with questions the statements act as answers to questions rather than independent statements.

For more information on defining taxon names using the <TaxonNames> element, see the topic [[TaxonNames][Defining taxon names]].
|

Note that taxa can also be arranged into hierarchies. See the topic [[TaxonHierarchies][Defining taxon hierarchies]] for more information.

<Scope> describes the taxon or set of taxa to which the description applies.
|
|
|
|
The <Result> element may include a <Subkey> element, which points to another complete dichotomous key. This allows a main/subkey arrangement, for example a key to the genera of a family with results leading to a subkey identifying the species within each genus.

Dichotomous keys (Box 2.3.1) are specialised identification tools comprising fragments of descriptive data arranged in couplets forming a branching tree. Each fragment (lead) comprises a small (occasionally verbose) natural-language description.

While dichotomous keys can be presented in various formats, the essential elements of all dichotomous keys are identical. Each consists of a tree of questions, each with two (or occasionally more) possible choices, each choice leading to another question or a taxon. SDD represents this with lists of <Questions> and <Leads>. The [[IdentificationKey][<IdentificationKey>]] element also contains a [[SddScope][<Scope>]] element, where the entities covered by the description may be defined.

These consistent elements are represented in SDD with the following structure.
