Hi Isabel, I think the issue you are running into is a by-product of the fact that DSpace does NOT inherently "understand" METS.
When you ingest METS into DSpace, DSpace will parse the METS file and attempt to translate it into Dublin Core metadata along with basic Database relationships. Unfortunately, when that same information is exported back to METS via OAI-PMH, it looks like we currently do not regenerate a <structMap> from the database relationships by default. This happens because, by default, the OAI-PMH interfaces uses the "org.dspace.content.packager.DSpaceMETSDisseminator" which just generates a very simplistic METS file (without a <structMap>). If you are using DSpace 1.7.x or above, you might be able to tell the OAI-PMH interface to instead use the "org.dspace.content.packager.DSpaceAIPDisseminator" class which generates a more complex METS file (which does include a basic <structMap>, which just points at the parent object). This AIP format is described at: https://wiki.duraspace.org/display/DSDOC18/DSpace+AIP+Format (Again, this format is only supported in DSpace 1.7.x or above) I will warn though that I've *NEVER* tried this, but it looks like you can change your dspace.cfg file to tell the OAI-PMH interface to instead use the DSpaceAIPDisseminator by redefining the "METS" plugin to point at the DSpaceAIPDisseminator (WARNING: DO NOT TRY THIS ON PRODUCTION UNTIL YOU HAVE TESTED IT THOROUGHLY ON ANOTHER SERVER. I'm not sure if this will affect other areas of DSpace.) Change The following in your dspace.cfg (NOTE the repetition "DSpaceAIPDisseminator" and "DSpaceAIPIngester" as it is defined as both the "AIP" and "METS" packagers.) plugin.named.org.dspace.content.packager.PackageDisseminator = \ org.dspace.content.packager.DSpaceAIPDisseminator = AIP, \ org.dspace.content.packager.DSpaceAIPDisseminator = METS, \ org.dspace.content.packager.RoleDisseminator = DSPACE-ROLES plugin.named.org.dspace.content.packager.PackageIngester = \ org.dspace.content.packager.DSpaceAIPIngester = AIP, \ org.dspace.content.packager.PDFPackager = Adobe PDF, PDF, \ org.dspace.content.packager.DSpaceAIPIngester = METS, \ org.dspace.content.packager.RoleIngester = DSPACE-ROLES However, as I warned, I'm not sure if the above change will affect other areas of DSpace which attempt to use the "METS" packager configured in dspace.cfg. So, it would also be possible to programmatically change the org.dspace.content.packager.DSpaceMETSDisseminator code so that it adds the <structMap> that you want -- you could do this in any version of DSpace.
