  • This line was added.
  • This line was removed.
  • Formatting was changed.


  1. Backup Your DSpace. First, and foremost, make a complete backup of your system, including:
    • A snapshot of the database. To have a "snapshot" of the PostgreSQL database, you need to shut it down during the backup. You should also have your regular PostgreSQL Backup output (using Postgres' pg_dump command).
    • Wiki Markup
      The asset store (_\[dspace\]/assetstore_ by default)
    • Your configuration files and customizations to DSpace (including any customized scripts).
  2. Download DSpace 1.7.0 Retrieve the new DSpace 1.7.0 source code either as a download from or check it out directly from the SVN code repository. If you downloaded DSpace do not unpack it on top of your existing installation. Refer to Installation Instructions, Step 3 for unpacking directives.
  3. Stop Tomcat. Take down your servlet container. For Tomcat, use the $CATALINA_HOME/bin/ script. (Many Unix-based installations will have a startup/shutdown script in the /etc/init.d or /etc/rc.d directories).
  4. Apply any customizations. If you have made any local customizations to your DSpace installation they will need to be migrated over to the new DSpace. These are normally housed in one of the following places:
    • Wiki Markup
      JSPUI modifications: _\[dspace-source\]/dspace/modules/jspui/src/main/webapp/_
    • Wiki Markup
      XMLUI modifications: _\[dspace-source\]/dspace/modules/xmlui/src/main/webapp/_
  5. Update Configuration Files. Some parameters have changed and some are new. You can either attempt to make these changes in your current 1.6.x dspace.cfg file, or you can start with a new 1.7.0 dspace.cfg and re-modify it as needed. Configuration changes are noted below:
    • *CORRECTION*  There was a missing hyphen "-" in the property key for mail character set:
      Code Block
      # Set the default mail character set. This may be over ridden by providing a line
      # inside the email template "charset: <encoding>", otherwise this default is used.
      #mail.charset = UTF-8
    • *CORRECTION* This was moved from the end of the solr configuration section to just under Logging Configurations:
      Code Block
      # If enabled, the logging and the solr statistics system will look for
      # an X-Forward header. If it finds it, it will use this for the user IP Address
      # useProxies = true
    • *CHANGE* The MediaFilter is now able to process Power Point Text Extracter
      Code Block
      #Names of the enabled MediaFilter or FormatFilter plugins
      filter.plugins = PDF Text Extractor, HTML Text Extractor, \
                                       PowerPoint Text Extractor, \
                                       Word Text Extractor, JPEG Thumbnail
      # [To enable Branded Preview]: remove last line above, and uncomment 2 lines below
      #                        Word Text Extractor, JPEG Thumbnail, \
      #                        Branded Preview JPEG
      #Assign 'human-understandable' names to each filter = \ = PDF Text Extractor, \ = HTML Text Extractor, \ = Word Text Extractor, \ = PowerPoint Text Extractor, \ = JPEG Thumbnail, \ = Branded Preview JPEG
      #Configure each filter's input format(s) = Adobe PDF = HTML, Text = Microsoft Word = Microsoft Powerpoint, Microsoft Powerpoint XML = BMP, GIF, JPEG, image/png = BMP, GIF, JPEG, image/png
    • *CHANGE* The Crosswalk Plugin Configuration has changed with additional lines. Edit your file accordingly:
      Code Block
      # Crosswalk Plugin Configuration:
      #   The purpose of Crosswalks is to translate an external metadata format to/from
      #   the DSpace Internal Metadata format (DIM) or the DSpace Database.

        org.dspace.content.crosswalk.LicenseStreamDisseminationCrosswalk = DSPACE_DEPLICENSE
    • *CHANGE* The Packager Plugin Configuration has changed considerably. Carefully revise your configuration file:
      Code Block
       Packager Plugin Configuration:
      #   Configures the ingest and dissemination packages that DSpace supports.
      #   These Ingester and Disseminator classes support a specific package file format
      #   (e.g. METS) which DSpace understands how to import/export.  Each Packager
      #   plugin often will use one (or more) Crosswalk plugins to translate metadata (see above). = \
        org.dspace.content.packager.DSpaceAIPDisseminator = AIP, \
        org.dspace.content.packager.DSpaceMETSDisseminator = METS, \
        org.dspace.content.packager.RoleDisseminator = DSPACE-ROLES

        org.dspace.content.packager.DSpaceMETSIngester = METS, \
        org.dspace.content.packager.RoleIngester = DSPACE-ROLES
    • *CHANGE* The Mets Ingester configuration has change and been updated. Carefully edit:
      Code Block
      #### METS ingester configuration:
      # These settings configure how DSpace will ingest a METS-based package
      # Configures the METS-specific package ingesters (defined above)
      # 'default' settings are specified by 'default' key
      # Default Option to save METS manifest in the item: (default is false)

      # Default Option to make use of collection templates when using the METS ingester (default is false)
      mets.default.ingest.useCollectionTemplate = false
      # Default crosswalk mappings
      # Maps a METS 'mdtype' value to a DSpace crosswalk for processing.
      # When the 'mdtype' value is same as the name of a crosswalk, that crosswalk
      # will be called automatically (e.g. mdtype='PREMIS' calls the crosswalk named
      # 'PREMIS', unless specified differently in below mapping)
      # Format is 'mets.default.ingest.crosswalk.<mdType> = <DSpace-crosswalk-name>'

      # Locally cached copies of METS schema documents to save time on ingest.  This
      # will often speed up validation & ingest significantly.  Before enabling
      # these settings, you must manually cache all METS schemas in
      # [dspace]/config/schemas/ (does not exist by default).  Most schema documents
      # can be found on the website.
      # Enable the below settings to pull these *.xsd files from your local cache.

      #### AIP Ingester & Disseminator Configuration
      # These settings configure how DSpace will ingest/export its own
      # AIP (Archival Information Package) format for backups and restores
      # (Please note, as the DSpace AIP format is also METS based, it will also
      # use many of the 'METS ingester configuration' settings directly above)
      # AIP-specific ingestion crosswalk mappings
      # (overrides 'mets.default.ingest.crosswalk' settings)
      # Format is 'mets.dspaceAIP.ingest.crosswalk.<mdType> = <DSpace-crosswalk-name>'

      # (by default, EPerson creation is already handled by 'DSPACE-ROLES' Crosswalk)
      #mets.dspaceAIP.ingest.createSubmitter = false
      ## AIP-specific Disseminator settings
      # These settings allow you to customize which metadata formats are exported in AIPs
      # Technical metadata in AIP (exported to METS <techMD> section)
      # Format is <label-for-METS>:<DSpace-crosswalk-name> [, ...] (label is optional)

      # If unspecfied, defaults to "MODS, DIM"
      aip.disseminate.dmd = MODS, DIM
    • *NEW* A new property has been added to control the discovery index for the Event System Configuration:
      Code Block
      # consumer to maintain the discovery index
      event.consumer.discovery.class = org.dspace.discovery.IndexEventConsumer
      event.consumer.discovery.filters = Community|Collection|Item|Bundle+Add|Create|Modify|Modify_Metadata|Delete|Remove
    • *NEW* License bundle display is now configurable. You are able to either display or suppress.
      Code Block
      # whether to display the contents of the licence bundle (often just the deposit
      # licence in standard DSpace installation = false
    • *CORRECTION* Thumbnail generation. The width and height of generated thumbnails had a missing equal sign.
      Code Block
      # maximum width and height of generated thumbnails
      thumbnail.maxwidth  = 80
      thumbnail.maxheight = 80
    • *CORRECTION and ADDITION* Authority Control Settings have changed. Formerly called ChoiceAuthority, it is now referred to as DCInputAuthority.
      Code Block
      ## The DCInputAuthority plugin is automatically configured with every
      ## value-pairs element in input-forms.xml, namely:
      ##   common_identifiers, common_types, common_iso_languages
      ## The DSpaceControlledVocabulary plugin is automatically configured
      ## with every *.xml file in [dspace]/config/controlled-vocabularies,
      ## and creates a plugin instance for each, using base filename as the name.
      ## eg: nsi, srsc.
      ## Each DSpaceControlledVocabulary plugin comes with three configuration options:
      # = <true|false>    # default: true
      # vocabulary.plugin._plugin_.hierarchy.suggest = <true|false>  # default: true
      # vocabulary.plugin._plugin_.delimiter = "<string>"            # default: "::"
      ## An example using "srsc" can be found later in this section
    = \
      # org.dspace.content.authority.DCInputAuthority, \
      # org.dspace.content.authority.DSpaceControlledVocabulary
    • *NEW* Controls autocomplete for authority control
      Code Block
      ## demo: subject code autocomplete, using srsc as authority
      ## (DSpaceControlledVocabulary plugin must be enabled)
      #choices.plugin.dc.subject = srsc
      #choices.presentation.dc.subject = select = true
      #vocabulary.plugin.srsc.hierarchy.suggest = true
      #vocabulary.plugin.srsc.delimiter = "::"
    • *NEW* You are now able to order your bitstreams by sequence id or file name.
      Code Block
      #### Ordering of bitstreams ####
      ## Specify the ordering that bitstreams are listed.
      ## Bitstream field to sort on.  Values: sequence_id or name. Default: sequence_id
      #webui.bitstream.order.field = "sequence_id"
      ## Direction of sorting order. Values: DESC or ASC. Default: ASC
      #webui.bitstream.order.direction = ASC
    • *NEW* DSpace now includes a metadata mapping feature that makes repository content discoverable by Google Scholar:
      Code Block
      ##### Google Scholar Metadata Configuration #####
      google-metadata.config = ${dspace.dir}/config/crosswalks/
      google-metadata.enable = true
    • *NEW* XMLUI is now able to concatenate CSS, JS and JSON files:
      Code Block
      # Enabling this property will concatenate CSS, JS and JSON files where possible.
      # CSS files can be concatenated if multiple CSS files with the same media attribute
      # are used in the same page. Links to the CSS files are automatically referring to the
      # concatenated resulting CSS file.
      # The theme sitemap should be updated to use the ConcatenationReader for all js, css and json
      # files before enabling this property.
      #xmlui.theme.enableConcatenation = false
      # Enabling this property will minify CSS, JS and JSON files where possible.
      # The theme sitemap should be updated to use the ConcatenationReader for all js, css and json
      # files before enabling this property.
      #xmlui.theme.enableMinification = false
    • *NEW* XMLUI Mirage Theme. This is a new theme with it's own configuration:
      Code Block
      ### Setings for Item lists in Mirage theme ###
      # What should the emphasis be in the display of item lists?
      # Possible values : 'file', 'metadata'. If your repository is
      # used mainly for scientific papers 'metadata' is probably the
      # best way. If you have a lot of images and other files 'file'
      # will be the best starting point
      # (metdata is the default value if this option is not specified)
      #xmlui.theme.mirage.item-list.emphasis = file
    • *NEW* OAI Response default change.
      Code Block
      # DSpace by default uses 100 records as the limit for the oai responses.
      # This can be altered by enabling the oai.response.max-records parameter
      # and setting the desired amount of results.
      oai.response.max-records = 100
    • *CHANGE* EPDCX property key has been renamed.
      Code Block
      # Define the metadata type EPDCX (EPrints DC XML)
      # to be handled by the SWORD crosswalk configuration
      mets.default.ingest.crosswalk.EPDCX = SWORD
    • *NEW* New SOLR Statistic Property keys:
      Code Block
      # Timeout for the resolver in the dns lookup
      # Time in milliseconds, defaults to 200 for backward compatibility
      # Your systems default is usually set in /etc/resolv.conf and varies
      # between 2 to 5 seconds, to high a value might result in solr exhausting
      # your connection pool
      solr.resolver.timeout = 200
      # Enable/disable logging of spiders in solr statistics.
      # If false, and IP matches an address in solr.spiderips.urls, event is not logged.
      # If true, event will be logged with the 'isBot' field set to true
      # (see solr.statistics.query.filter.* for query filter options)
      # Default value is true.
      #solr.statistics.logBots = true
  6. Build DSpace. Run the following commands to compile DSpace.:
    Code Block
    cd [dspace-source]/dspace/
    mvn -U clean package
    Wiki Markup
     You will find the result in _\[dspace-source\]/dspace/target/dspace-\[version\]-build.dir_ . Inside this directory is the compiled binary distribution of DSpace. Before rebuilding DSpace, the above command will clean out any previously compiled code ('clean') and ensure that your local DSpace JAR files are updated from the remote maven code repository.
  7. Update DSpace. Update the DSpace installed directory with the new code and libraries. Issue the following commands:
    Code Block
    cd [dspace-source]/dspace/target/dspace-[version]-build.dir
    ant -Dconfig=[dspace]/config/dspace.cfg update
  8. Update the Database. You will need to run the 1.6.x to 1.7.x database upgrade script.
    • For PostgreSQL:
      Code Block
      psql -U [dspace-user] -f [dspace-source]/dspace/etc/postgres/database_schema_16_17.sql [database name]
      (Your database name is by default 'dspace'). Example:
      Code Block
      psql -U dspace -f [dspace-source]/dspace/etc/postgres/database_schema_16_17.sql dspace
    • For Oracle: Execute the upgrade script, e.g. with sqlplus, recording the output:
      1. Wiki Markup
        Start SQL*Plus with {{sqlplus \[connect args\]}}
      2. Record the output: SQL> spool 'upgrade.lst'
      3. Wiki Markup
        Run the upgrade script {{SQL> @\[dspace-source\]/dspace/etc/oracle/database_schema_16_17.sql}}
      4. Turn off recording of output: SQL> spool off
  9. Generate Browse and Search Indexes. It's always good policy to rebuild your search and browse indexes when upgrading to a new release. To do this, run the following command from your DSpace install directory (as the 'dspace' user):
    Code Block
    [dspace]/bin/dspace index-init
  10. Wiki Markup
    *Deploy Web Applications*. If your servlet container (e.g. Tomcat) is not configured to look for new web applications in your {{\[dspace\]/webapps}} directory, then you will need to copy the web applications files into the appropriate subdirectory of your servlet container.  For example: 
    Code Block
    cp -R [dspace]/webapps/* [tomcat]/webapps/
  11. Restart servlet. Now restart your Tomcat/Jetty/Resin server program and test out the upgrade.
