• Plugin: an eclipse plugin, e.g. org.cs3.cultivate.core or org.cs3.cultivate.structure
• Repository: Executes and caches all queries, smell detectors and metrics
• Detector: Former concept, a Detector was either a metric or a smell ¹⁾
• Metric: Returns a Metric value and where the metric was measured, has a generic java representation and different prolog implementations
• Smell: Returns where a Smell occures, has a generic java representation and different prolog implementations
• Query: The Java-Part of a Prolog Query (TermQuery, PackageDependencyQuery)
• Prolog-Query: The Prolog-Part of a Query
• Query Results: Java object that represents the result of a query
• Name (or Identifier): The name of a java element like class, interface, method, field, paramter, local variable.

• QueryDescription

Each query can have a description to be shown on the java part.

   query_description(+queryName,+queryType, +Description).
   e.g.  query_description(nopSmell,smell,'empty statement').

• Smell

  smell(+smellName,-ListOfStatementIDs)

• Metric

   metric(+metricName, -ID,-ComputedMetric). 
   metric_attributes(+metricName, +Range, +Threshold)

• Dependency (This fits neither as a smell nor metric)

  dependency_package(DependentId,DependeeId, SccNumber,DependencyDegree).
  dependency_class(DependentId,DependeeId,DependencyDegree).

• TermMetric

   termmetric(+metricName,?Scope,-ID, - [(Term,ComputedMetric)]).

• TermQuery

  Each differ in syntax, all start with termquery(+queryName,..).

• ArchitectureQueries?
• Inheritance/Implementation
