Package org.wikidata.wdtk.examples

Class ClassPropertyUsageAnalyzer

java.lang.Object

org.wikidata.wdtk.examples.ClassPropertyUsageAnalyzer

All Implemented Interfaces:

EntityDocumentProcessor

public class ClassPropertyUsageAnalyzer
extends Object
implements EntityDocumentProcessor

This advanced example analyses the use of properties and classes in a dump file, and stores the results in two CSV files. These files can be used with the Miga data viewer to create the Wikidata Class and Properties browser. You can view the settings for configuring Miga in the Miga directory for this app.

However, you can also view the files in any other tool that processes CSV. The only peculiarity is that some fields in CSV contain lists of items as values, with items separated by "@". This is not supported by most applications since it does not fit into the tabular data model of CSV.

The code is somewhat complex and not always clean. It should be considered as an advanced example, not as a first introduction.
