Description

Sometimes a single record may contain multiple items within it, for example a METS document that has references to 20 different images, and you need to extract these components individually. A GroupTransformer will take a Record and turn it into a DocumentGroup with multiple Documents in it. This can also be used for extracting components for indexing, for example pages from a TEI record.

Implementations

• groupTransformer.XPathGroupTransformer
  Extract each occurence of the XPath and treat it as a new document.
