Package org.dspace.content.crosswalk

Provides an API and implementations of metadata crosswalks, which are directional mappings from one schema to another, performed in the context of Item ingestion or dissemination. Most crosswalks are driven by a mapping in a file, which reside in config/crosswalks.

Crosswalk Interfaces

The principle interfaces are for ingest and dissemination contexts, i.e. the IngestionCrosswalk interface consists of the methods:

public void ingest(Context context, DSpaceObject dso, List metadata)
public void ingest(Context context, DSpaceObject dso, Element root)

The DisseminationCrosswalk interface has methods:

public Namespace[] getNamespaces()
public String getSchemaLocation()
public boolean canDisseminate(DSpaceObject dso)
public List disseminateList(DSpaceObject dso)
public Element disseminateElement(DSpaceObject dso)

Crosswalk Implementations

Crosswalks exist for many formats, includings DC, QDC, METs, MODs, Premis, and a general implementation employing an XSLT stylesheet.

Interface Summary

Exception Summary

Exception	Description
CrosswalkException	Superclass for more-specific crosswalk exceptions.
CrosswalkInternalException	Something went wrong inside the crosswalk, not necessarily caused by the input or state (although it could be an incorrectly handled pathological case).
CrosswalkObjectNotSupported	Something went wrong inside the crosswalk, not necessarily caused by the input or state (although it could be an incorrectly handled pathological case).
MetadataValidationException	This indicates a problem with the input metadata (for submission) or item state (dissemination).
