Agenda

Discussion

  • Enrique: started to deploy Nextcloud
  • Mahdi: good discussions with Joern and Giuseppe for the WAYF implementation and the protections to be implemented in Reva against attacks. Several PRs were opened, all linked from https://github.com/cs3org/OCM-STA/issues/1 including videos demonstrating the UI interactions
  • Joern: PRs in OpenCloud could be merged rapidly, make them "Ready for review"
  • Mahdi: an OCM reference implementation could be done in Go, in such a way that all Reva implementations could benefit from it
  • Giuseppe: videos well appreciated at the EOSC Symposium (credits to Richard!), could be reused in future events. Richard: could also be improved, the GUI is always very similar between the different vendors, some visual clue about the fact that we run a federation of sites would be beneficial. Giuseppe: the CERN folks produced a video about federated workflows with REANA, where a map of Europe with the different sites is featured
  • IETF WG interim meeting: a doodle(-like) will be sent to agree on a date for the meeting, which will take place at around 16.30-17.00 CET to allow for participation from the US West Coast.

Discussion

  • STA Project contract is signed on the 16:th, and work has started, Mahdi and Enrique are main developers.
  • Working group is well under way at IETF, IESG voting to be done at 23:rd.
    • Micke will represent at IETF 124 at HotRFC's with video demos.
  • New spec version tagged 1.2.2.
  • EOSC EFSS Federation tests, readiness for the EOSC Symposium demo
    • Invitations: Works Nextcloud <-> CERNBox <-> oCIS <-> OpenCloud.
    • Shares: Works Nextcloud <-> CERNBox, CERNBox <-> oCIS/OpenCloud, but not Nextcloud <-> oCIS/OpenCloud.
  • OpenCloud will set up a node and we will record some videos on it.
  • Spec: should we expire shares/invite?
    • We will use IETF mailing list/ Github discussions to discuss.

Agenda

  • PRs review
  • EOSC EFSS Federation tests, readiness for the EOSC Symposium demo

Discussion

  • PRs review
  • EOSC EFSS Federation tests, readiness for the EOSC Symposium demo
    • Invitation: NC <--> CERNBox OK, EOSC EU Node (EEN) needs to trust the federation
    • Sharing: work in progress, nothing works yet. NC-to-NC works in a non OCM compliant way
    • Remote access: on hold, depends on Sharing to work
  • OpenCloud implementation (like oCIS) does bearer auth only, so likely to work with CERNBox but not with Nextcloud
  • Discussion about the Invitation flow in the context of OpenCloud

Agenda

  • Grants for OCM work from GEANT (SUNET) and STA (PonderSource)

Discussion

  • [Richard] FileSender is seeking OCM support
  • rclone and OCM integration for file transfer: a PoC was done during ScienceMesh, with Reva implementing 3rd-party file transfers with https
    • Data Commons also have similar thing to do, fetching data after sharing
  • IETF WG progress: the WG may be appointed just before or at IETF 124 Montreal
  • EOSC Symposium: demonstrations yet to be defined

  • Federation tester ideas
  • Possibility of using DNS SRV records as fallback for .well-known
  • Micke and Antoons WAYF app for Nextcloud was demonstrated at the EFSS sub-group meeeting of the EOSC federation buildup task force
  • Upcoming presentations about OCM:
    • Richard gives today a lightning talk at Nordunet Community Workshop in Copenhagen
    • Micke will attend IETF 124 Montreal and proposes an HotRFC lightning talk
    • In the same days, the EOSC Symposium takes place and demos are foreseen
    • A SIG-CISS meeting is being organized by Geant in Bologna, with focus on Sync&Share and storage federations. Micke and Giuseppe will attend and present the current status of OCM
    • At next CS3 workshop there will be a comprehensive session about those events

Agenda

Actions

  • For Micke or Giuseppe
    • Get in contact with Maxence Lange to understand how group sharing is implemented in NextCloud - is this actually federated?

Discussion

  • Giuseppe: Reverse engineering how NextCloud does group sharing is not our job, get NextCloud developers involved and see how their implementation works.
  • SUNET received funding from GEANT to develop a storage module for SurfResearchCloud and the proposed solution includes OCM. Implementation and specification for group/federated sharing could be done here and the effort can be driven by SUNET.
  • The W3C Community Group is about to be closed. There's an issue with intellectual property, we cannot be in both the IETF and WC3.

Agenda

Actions

  • Email the IETF mailing list about the charter feedback and submit a PR today. - Done and done
  • We should have minimal security section - PR ready for review #221
  • Re-order the sections in IETF I-D, such as Introduction, etc. - PR #246
  • Re-upload the latest changes afterwards to IETF data tracker so people can review.
  • Clean ocm-test-suite, build images in cs3org and use GitHub Actions to build images and push to cs3org GitHub Container Registry ghcr.io

Discussion

  • We'll wait for Matthias to apply the requested changes for the OCM address PR.
  • The line length linter for IETF I-D, CI Job is ready and good.
  • We will wait for Pierre to join a meeting, and continue discussion then.

Regrets

Agenda

  • IETF Meeting 123 Debrief:
    • We were mentioned on JMAP WG
  • New logistics

Introductions

  • Pierre Thierry: developed a decentralized binary format that is related to CBOR.

Actions

  • We should demonstrate people are interested so Vienna is better option for the in person BoF.
  • We should keep the momentum as per Andy's email, Micke might go to Montreal or China to have side meeting.
  • Having an online BoF is also an option.
  • We should fork the IETF charter repository into personal spaces. we host it on Micke space.
  • We are considering changing the time of weekly meeting.
  • Discussing with W3C at next Tuesday 4 PM when Michiel is back, about transferring OCM from W3C to IETF.

Discussion

OCM protocol following REST

  • Pierre Thierry: it's a good idea to hint the OCM endpoints in the OCM payloads, following the REST architecture 
    •   {
  	invitations: "/invitation",
  	share-accept: "/share-accept",
  }
  • Giuseppe: We should not break the compatibility, OCM doesn't concern itself with the actual data transfer
  • Giuseppe: Share and Invite cannot be changed, authentication maybe, notification is harder.
  • Micke: We should be weary of breaking compatibility, but we should also make the protocol better. sending the capabilities along would make protocol less chatty, it is worth looking into
  • Pierre Thierry: new clients would implement it, and legacy implementations would follow later.
  • Micke: gradual departure from hard coded paths is a good idea.

GitHub notification in mailing list

  • Giuseppe: filter out useless notifications
  • Micke: We can use other tools; the downside is that we should use a dedicated server or virtual machine.
