Class CitationDocumentServiceImpl

java.lang.Object

org.dspace.disseminate.CitationDocumentServiceImpl

All Implemented Interfaces:

CitationDocumentService, org.springframework.beans.factory.InitializingBean

public class CitationDocumentServiceImpl
extends Object
implements CitationDocumentService, org.springframework.beans.factory.InitializingBean

The Citation Document produces a dissemination package (DIP) that is different that the archival package (AIP). In this case we append the descriptive metadata to the end (configurable) of the document. i.e. last page of PDF. So instead of getting the original PDF, you get a cPDF (with citation information added).

Description copied from interface: CitationDocumentService

Repository policy can specify to have a custom citation cover/tail page to the document, which embeds metadata. We need to determine if we will intercept this bitstream download, and give out a citation dissemination rendition. What will trigger a redirect/intercept? Citation enabled globally (all citable bitstreams will get "watermarked") modules/disseminate-citation: enable_globally OR The container is this object is whitelist enabled. - community: modules/disseminate-citation: enabled_communities - collection: modules/disseminate-citation: enabled_collections AND This User is not an admin. (Admins need to be able to view the "raw" original instead.) AND This object is citation-able (presently, just PDF) The module must be enabled, before the permission level checks happen.
