Class LuceneGenerator

java.lang.Object
  org.eaglei.search.datagen.AbstractGenerator
      org.eaglei.search.provider.lucene.LuceneGenerator

public class LuceneGenerator
extends org.eaglei.search.datagen.AbstractGenerator

Generators test data (as a Lucene index) using the eagle-i ontology.

• Generates resources for a random number of labs for each instance of the university class.
• For each lab, creates a random number of resources for each subclass of the "top-level" class (e.g. instrument, technique, etc.). The class of each of these resources is randomly selected from the hierarchy.
• A lucene document is created for each lab and resource with fields according to the schema outlined in LuceneIndexer.
