cubicweb-keyword 2.1.0

classification schemes system for the Cubicweb framework

The keyword cube provides classification by using hierarchies of keywords to classify content.

Each classification is represented using a Classification entity, which will hold a keywords tree.

There is two types of keywords:

• Keyword which contains a description,

• CodeKeyword which contains the keyword description and the associated code.

In order to link an entity to a keyword, you have to add a relation

applied_to in the schema.

Each keyword has the subkeyword_of relation definition. This allows to navigate in the classification without a Modified Preorder Tree Traversal representation of the data.

Some methods are defined in order to get parents and children or get the status of a keyword (leaf or root).

See also cubicweb-tag as another (simpler) way to classify content.
