Package org.dspace.disseminate

Class CitationDocumentServiceImpl

java.lang.Object
org.dspace.disseminate.CitationDocumentServiceImpl
All Implemented Interfaces:
CitationDocumentService, InitializingBean
public class CitationDocumentServiceImpl extends Object implements CitationDocumentService, 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).

      public Boolean isCitationEnabledForBitstream(Bitstream bitstream, Context context) throws SQLException
      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 "allow list" 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.

    • makeCitedDocument

      public org.apache.commons.lang3.tuple.Pair<byte[],Long> makeCitedDocument(Context context, Bitstream bitstream) throws IOException, SQLException
      Description copied from interface: CitationDocumentService
      Creates a cited document from the given bitstream of the given item. This requires that bitstream is contained in item.

      The Process for adding a cover page is as follows:

      1. Load source file into PdfReader and create a Document to put our cover page into.
      2. Create cover page and add content to it.
      3. Concatenate the coverpage and the source document.
      Specified by:
      makeCitedDocument in interface CitationDocumentService
      Parameters:
      context - DSpace context
      bitstream - The source bitstream being cited. This must be a PDF.
      Returns:
      The temporary File that is the finished, cited document.
      Throws:
      IOException - if IO error
      SQLException - if database error
