Bundle: org.eclipse.smila.processing.pipelets.aperture.ApertureMimeTypeIdentifier


This ProcessingService is used to identify the mimetype of a document. The service uses either the document's content (a byte[]), a file extension or both. So it is not required that the record contains a value for both properties ContentAttachment and FileExtensionAttribute. The identified MimeType is store in an attribute in the record.

Useful Information

Note that this ProcessingService also is a DeclarativeService that implements interface org.eclipse.smila.processing.pipelets.aperture.MimeTypeIdentifier and can be used outside the workflow as well.
