GLAMpipe can export data to web services via export nodes.
The process of uploading data has two steps. First the original data must me mapped to the schema of target DSpace. Next, the mapped data is uploaded to DSpace.
The mapping is done with DSpace mapping node. You can find it from Process data > Map data > DSpace 6: map data. You need to choose the target DSpace.
Export to DSpace is done via DSpace 6: add item that can be find from Export data > export to web.
When you create the export node, you need to give the mapped data field as input.
Then, in the settings you pass your user credentials. It is a good idea to try first with single document first and check the result before making batch run.
