Hi,
At this time, we do not have updated IDE integration instructions for DSpace 7. However, I can verify that the DSpace 7 backend works very similarly to DSpace 6... so older integrations that worked for DSpace 6 should likely still work for DSpace 7.
These IDE integration instructions tend to be donated by volunteers. I haven't had anyone volunteer to write one of these for DSpace 7 yet, so there's nothing that I can share.
