Interface StreamIngestionCrosswalk

All Known Implementing Classes:

CreativeCommonsRDFStreamIngestionCrosswalk, LicenseStreamIngestionCrosswalk, NullStreamIngestionCrosswalk

public interface StreamIngestionCrosswalk

A class implementing this interface can crosswalk metadata directly from a stream (assumed to be in a specific format) to the object.

Stream-oriented crosswalks are intended to be used for metadata formats which are either (a) not XML-based, or (b) too bulky for the DOM-ish in-memory model developed for the METS and IMSCP packagers. The METS packagers (all subclasses of AbstractMETSDisseminator / AbstractMETSIngester are equipped to call these crosswalks as well as the XML-based ones, just refer to the desired crosswalk by its plugin name.

in - input stream containing the metadata.

MIMEType - MIME type of the ???

Throws:

CrosswalkInternalException - (CrosswalkException) failure of the crosswalk itself.
