---------------------------------
Summary: Composite Properties
Key: TIKA-927
URL: https://issues.apache.org/jira/browse/TIKA-927
Project: Tika
Issue Type: Improvement
Components: metadata
Affects Versions: 1.1
Reporter: Ray Gauss II
Attachments: tika-composite-properties-core.diff
A composite property type would be useful for maintaining backwards
compatibility when migrating old properties or aliasing a single primary
property to several secondary fields.
To achieve this the Property class could allow for defining a composite type
which aliases a primary Property and an optional list of
secondaryExtractProperties which can be used to set additional metadata
properties with the same value as the primary.
The name of the composite property would be taken from its primary property.
The primary and secondary children of a composite property must not be
composite properties themselves or a PropertyTypeException will be thrown.
