I have a CMIS server, and want users to access it as a SMB 3 server.

CMIS server <-----> gateway <-----> SMB 3 clients

Is there such a gateway?

Any OS and price is fine (I would prefer open source and runnable on Linux though).

Users should be able to:

  • Browse folders of the CMIS server just like if it was a SMB 3 server
  • See files
  • Download files
  • See files' metadata

Bonus for write operations:

  • Create files/folders
  • Modify files/folders
  • Delete files/folders
  • Modify metadata
  • Have you tried to mount the CMIS and export that mount via regular SAMBA ?

  • @Marged: Doing so would lose all of the metadata, I believe. By the way, what product are you thinking of to "mount the CMIS"?

MoSMB, an SMB3 server on linux has the capability to interact with any underlying file/object store. You will need to add a plugin to interact with CMIS APIs. Currently, MoSMB interacts with any posix filesystem and any S3-compatible object store. MoSMB can exposes any bucket as an SMB3 share and objects can be browsed as files. It should be easily possible to write a plugin for CMIS server. Checkout the video 'MoSMB 3.0 accessing a S3 compatible Object Store' at link https://www.mosmb.com/videos/

  • Are you affiliated with MoSMB? If yes, please disclose it.

I know 2 servers that can give you what you want.

Non-open source:

  1. Visuality Systems : NQE(for embedded platform) or NQS(for storage platform) depend on your network.

These product are portable to any OS (as much as I know). The license is commercial(so you have to buy this server) and have very good support.

Open source

  1. Samba server - this should be build-in in your Linux OS.

If you seek for support and porting i suggest the NQS/E, if you just want it to work you can choose the SAMBA server.

  • No, these are just SMB servers. They are not gateways from CMIS to SMB.
