OCM changes and missing example configs

[MahdiBaghbani]

Debugging sharing between Nextcloud and CERNBox I see a bit of duplication that is not reflected in the configs:

/sciencemesh is used for:

• The [http.services.sciencemesh] HTTP service (web app access, invite handling)
• Legacy web app URLs like /external/sciencemesh/{token}/...
• Configured via ocm_mount_point = "/sciencemesh"

/ocm-received is used for:

• The new LibreGraph/Graph API (spaces-based web UI)
• The "Shared With Me" view in the modern ownCloud web interface
• Generated by EncodeOCMShareID() function

They both point to the same ocmreceived driver but serve different access patterns:

User clicks share in web UI (SharedWithMe)
    -> /remote.php/dav/spaces/ocm-received$... 
        -> /ocm-received/{shareId}
            -> ocmreceived driver

User accesses via web app link
    -> /external/sciencemesh/{token}/...
        -> /sciencemesh/{shareId}
            -> ocmreceived driver

So both mount points are needed for full functionality. The configuration should have both:

# dataprovider-sciencemesh.toml
[[grpc.services.storageprovider]]
driver = "ocmreceived"
mount_path = "/sciencemesh"    # legacy/web app access
...

[[grpc.services.storageprovider]]
driver = "ocmreceived"
mount_path = "/ocm-received"   # new LibreGraph/spaces UI
...

ok i'm wrong about this after testing further, the

# dataprovider-sciencemesh.toml
[[grpc.services.storageprovider]]
driver = "ocmreceived"
mount_path = "/sciencemesh"    # legacy/web app access

is not needed after all.

Found another bug testing the Reva with Nextcloud, see: #5414

[MahdiBaghbani]

Nextcloud still loves the https://

"owner": "admin-builtin@1.nextcloud.cloud.test.azadehafzar.io",
"shareWith": "4c510ada-c86b-4815-8820-42cdf82c3d51@https://1.cernbox.cloud.test.azadehafzar.io"

this is master branch btw

The final issue I run into is Nextcloud is OCM 1.0-proposal1 and Reva is 1.2, CERNBox is sending OCM 1.2 format, but Nextcloud only supports OCM 1.0.

Which is being worked on by Enrique

So the purpose of this issue is to be a reminder that Reva lacks config examples

Hey @MahdiBaghbani, Are you still working on this? If not, I can create a PR for the issue by adding missing config examples.

[MahdiBaghbani]

Still working on this. The missing examples belong in https://github.com/cs3org/reva-configs ; I am opening PRs there (Refs only; this issue stays open). Happy to coordinate if you find anything that isn't working and needs more PRs
