org.apache.tika.metadata.Property

All Implemented Interfaces:

java.lang.Comparable<Property>

public final class Property
extends java.lang.Object
implements java.lang.Comparable<Property>

XMP property definition. Each instance of this class defines a single metadata property like "dc:format". In addition to the property name, the value type and category (internal or external) of the property are included in the property definition. The available choice values are also stored for open and closed choice value types.

Since:

Apache Tika 0.7
