classification schemes system for the Cubicweb framework
Project description
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.
