All Implemented Interfaces:

PackageDisseminator

public class DSpaceAIPDisseminator
extends AbstractMETSDisseminator

Subclass of the METS packager framework to disseminate a DSpace Archival Information Package (AIP). The AIP is intended to be, foremost, a _complete_ and _accurate_ representation of one object in the DSpace object model. An AIP contains all of the information needed to restore the object precisely in another DSpace archive instance.

Configuration keys:

The following take as values a space-and-or-comma-separated list of plugin names that name *either* a DisseminationCrosswalk or StreamDisseminationCrosswalk plugin. Shown are the default values. The value may be a simple crosswalk name, or a METS MDsec-name followed by a colon and the crosswalk name e.g. "DSpaceDepositLicense:DSPACE_DEPLICENSE" # MD types to put in the sourceMD section of the object. aip.disseminate.sourceMD = AIP-TECHMD # MD types to put in the techMD section of the object (and member Bitstreams if an Item) aip.disseminate.techMD = PREMIS # MD types to put in digiprovMD section of the object. #aip.disseminate.digiprovMD = # MD types to put in the rightsMD section of the object. aip.disseminate.rightsMD = DSpaceDepositLicense:DSPACE_DEPLICENSE, \ CreativeCommonsRDF:DSPACE_CCRDF, CreativeCommonsText:DSPACE_CCTXT, METSRights # MD types to put in dmdSec's corresponding the object. aip.disseminate.dmd = MODS, DIM

Description copied from class: AbstractMETSDisseminator

Export the object (Item, Collection, or Community) as a "package" on the indicated OutputStream. Package is any serialized representation of the item, at the discretion of the implementing class. It does not have to include content bitstreams.

Use the params parameter list to adjust the way the package is made, e.g. including a "metadataOnly" parameter might make the package a bare manifest in XML instead of a Zip file including manifest and contents.

Throws an exception of the chosen object is not acceptable or there is a failure creating the package.

Specified by:

disseminate in interface PackageDisseminator

Overrides:

disseminate in class AbstractMETSDisseminator

Parameters:

context - DSpace context.

dso - DSpace object (item, collection, etc)

params - Properties-style list of options specific to this packager

pkgFile - File where export package should be written

Throws:

makeBitstreamURL

public String makeBitstreamURL(Bitstream bitstream,
                               PackageParameters params)

Get the URL by which the METS manifest refers to a Bitstream member within the same package. In other words, this is generally a relative path link to where the Bitstream file is within the Zipped up AIP.

For a manifest-only AIP, this is a reference to an HTTP URL where the bitstream should be able to be downloaded from. An external AIP names a file in the package with a relative URL, that is, relative pathname.

Specified by:

makeBitstreamURL in class AbstractMETSDisseminator

Parameters:

bitstream - the Bitstream

params - Packager Parameters

Returns:

String in URL format naming path to bitstream.

addStructMap

public void addStructMap(Context context,
                         DSpaceObject dso,
                         PackageParameters params,
                         edu.harvard.hul.ois.mets.Mets mets)
                  throws SQLException,
                         IOException,
                         AuthorizeException,
                         edu.harvard.hul.ois.mets.helper.MetsException

Adds another structMap element to contain the "parent link" that is an essential part of every AIP. This is a structmap of one div, which contains an mptr indicating the Handle of the parent of this object in the archive. The div has a unique TYPE attribute value, "AIP Parent Link", and the mptr has a LOCTYPE of "HANDLE" and an xlink:href containing the raw Handle value.

Note that the parent Handle has to be stored here because the parent is needed to create a DSpace Object when restoring the AIP; it cannot be determined later once the ingester parses it out of the metadata when the crosswalks are run. So, since the crosswalks require an object to operate on, and creating the object requires a parent, we cannot depend on metadata processed by crosswalks (e.g. AIP techMd) for the parent, it has to be at a higher level in the AIP manifest. The structMap is an obvious and standards-compliant location for it.

Specified by:

addStructMap in class AbstractMETSDisseminator

Parameters:

context - DSpace context

dso - Current DSpace object

params - Packager Parameters

mets - METS manifest

Throws:

SQLException

IOException

AuthorizeException

edu.harvard.hul.ois.mets.helper.MetsException

includeBundle

public boolean includeBundle(Bundle bundle)

By default, include all bundles in AIP as content.

However, if the user specified a comma separated list of bundle names via the "includeBundles" option, then check if this bundle is in that list. If it is, return true. If it is not, return false.

Specified by:

includeBundle in class AbstractMETSDisseminator

Parameters:

bundle - Bundle to check for

Returns:

true if bundle should be disseminated when disseminating Item AIPs
