- You can test that it is working by sending a request to:
[dspace.server.url]/[oai.path]/request?verb=Identify(e.g. http://localhost:8080/server/oai/request?verb=Identify) - The response should look similar to the response from the DSpace 7 Demo Server: httphttps://demoapi7.dspace.org/server/oai/request?verb=Identify
If you're using a recent browser, you should see a HTML page describing your repository. What you're getting from the server is in fact an XML file with a link to an XSLT stylesheet that renders this HTML in your browser (client-side). Any browser that cannot interpret XSLT will display pure XML. The default stylesheet is located in [dspace-source]/dspace-oai/src/main/resources/static/style.xsl and can be changed by configuring the stylesheet attribute of the Configuration element in [dspace]/config/crosswalks/oai/xoai.xml.

The harvest script can be called from both the CLI and REST API by calling "harvest". It uses the paramaters as defined in the following table.
| Short option | Long option | Argument | Explanation |
|---|---|---|---|
| -p | --purge | [none] | Delete all the items in the collection provided with the -c parameter. |
| -r | --run | [none] | Run the standard harvesting procedure for the collection provided with the -c parameter. |
| -g | --ping | [none] | Verify that the server provided through the -a parameter and the set provided through the -i parameter can be resolved and work. |
| -s | --setup | [none] | Set the collection provided with the -c parameter up for harvesting. The server will need to be provided through the -a parameter, and the oai set id needs to be provided by the -i parameter. |
| -S | --start | [none] | Start the harvest loop for all collections. |
| -R | --reset | [none] | Reset the harvest status on all collections. |
| -P | --purgeCollections | [none] | Purge all harvestable collections. |
| -o | --reimport | [none] | Reimport all items the items in the collection provided by the -c parameter. This is the equivalent of running both the -p and the -r command for the provided collection. |
| -c | --collection | [id-or-handle] | The harvesting collection (handle or id) |
| -t | --type | [type-code] | The type of harvesting: 0 for no harvesting, 1 for metadata only, 2 for metadata and bitstream references (requires ORE support), 3 for metadata and bitstreams (requires ORE support) |
| -a | --address | [url] | The address of the OAI-PMH server to be harvested |
| -i | --oai_set_id | [set-id] | The id of the PMH set representing the harvested collection. In case all sets need to harvested the value "all" should be provided. |
| -m | --metadata_format | [format] | The name of the desired metadata format for harvesting, resolved to namespace and crosswalk in the dspace.cfg |
| -h | --help | [none] | Print the help message |
| -e | --eperson | [email] | (CLI ONLY) The eperson that performs the harvest. When the command is used from the REST API, the currently logged in user will be used. |

dspace/bin/dspace harvest -s -c 123456789/123 -e harvest-user@dspace.org -a https://harvest.source.org -i harvest-set -m dc -t 1Replace the 123456789/123 with your collection, the harvest-user@dspace.org with an existing user in DSpace that has sufficient rights to perform the ingestion, https://harvest.source.org with the source you want to use, the harvest-set with the set/sets you want to harves or all in case you want to harvest all sets. The -m parameter indicated the metadata format to be used and the -t parameter indicates the harvest type to be used. When the value 0 is used for -t , harvesting will be disabled.
