Package Structure#

d3web defines the general package structure as follows:


The core consists of non-optional classes, whereas plugins includes optional classes. A plugin usually spans over multiple components.

For example, the package structure of the XCL problem-solver:

  • de.d3web.xcl: for the basic representation
  • de.d3web.xcl.inference: problem-solver functionality
  • problem-solver specific persistence


Knowledge Representation: de.d3web.core.knowledge#

All classes of the knowledge representation are included in this package. For instance, the definition of solutions and questions.

  • de.d3web.core.knowledge:
    IDObject, KnowledgeBase, Value, InfoStore

  • de.d3web.core.knowledge.terminology:
    Question (with sub-classes), QContainer, Choice, Solution
    Property, BasicProperties, MMInfo

  • de.d3web.core.knowledge.manage:
    KnowledgeBaseUtils, RuleFactory

Knowledge Base Persistence:

    XML/Jar persistence to read/write knowledge bases. Basic definitions of KnowledgeReaders, KnowledgeWriters, PersistenceManager
    FragmentHandler and for all plugins the corresponding fragment handlers

Inference: de.d3web.core.inference#

  • de.d3web.core.inference:
    PSMethod, PropagationManager, MethodKind, KnowledgeSlice, Action, Rule, Interface Condition

  • de.d3web.core.inference.condition:
    all AbstractCondition's implementing the interface Condition

Session: de.d3web.core.session#

  • de.d3web.core.session:
    Session, DefaultSession, Value (with sub-classes), Protocol, SessionManager, InterviewManager
  • de.d3web.core.session.blackboard:
    Blackboard, Fact, FactStorage, FactAggregation

Persistent Session Representation: de.d3web.core.records#
