Defining a Knowledge Base#

A new knowledge base is defined by the KnowledgeBase Markup. The following example defines a new knowledge base with the id CAR_FAULTS_DEMO_ID having the specified comment. All knowledge defined in the package "demo" are included in this knowledge base. With the optional annotation 'filename' you can specify a filename of the knowledge base when downloaded from the wiki. Otherwise, the name of the knowledge base is used as filename.

%%KnowledgeBase 
Car faults diagnosis
@ID: CAR_FAULTS_DEMO_ID
@Author: joba
@Affiliation: denkbares GmbH
@Status: BETA
@Version: 21
@Comment: Example car fault diagnosis knowledge base.
@uses: demo
@filename: demo.d3web
/%

That way, all knowledge defined throughout the wiki is included, when it is declared in the package "demo". Please note, that any knowledge markup ends in the default package "default", until it is defined otherwise.

Useful Advices#

We strongly recommend to make extensive use of copy & paste to avoid typos that could lead to misinterpretation or malfunctions.

Once you have begun to define some knowledge - say, for example, a question hierarchy - you may use copy & paste to insert question names wherever you need them (e.g., in rules...). That way you can ensure an identical naming.

An exact accordance of the names throughout all knowledge definitions is a required condition for a correct problem-solving behavior.
