Interconnected Private Clouds for Universities and Researchers
OpenCloudMesh is a joint international initiative under the umbrella of the GÉANT Association that is built on ownCloud’s open Federated Cloud sharing application programming interface (API) taking Universal File Access beyond the borders of individual Clouds and into a globally interconnected mesh of research clouds - without sacrificing any of the advantages in privacy, control and security an on-premises cloud provides. OpenCloudMesh provides a common file access layer across an organization and across globally interconnected organizations, whether the data resides on internal servers, on object storage, in applications like SharePoint or Jive, other ownClouds, or even external cloud systems such as Dropbox and Google (syncing them to desktops or mobile apps, making them available offline).
Concept document
The OpenCloudMesh concept document was produced by ownCloud Inc. and first distributed on 23 July 2015
Statement
All leading partners of the OpenCloudMesh project - GÉANT, CERN and ownCloud Inc. - are fully committed to the open API design principle. This means that - from day one - the OCM sharing API should be discussed, designed and developed as a vendor neutral protocol to be adopted by any on-premise sync&share product vendor or service provider. We acknowledge the fact that the piloting of the first working interface prototype will be carried out in an ownCloud environment that should not effect the adoption of the open API in any other vendor and provider domain.
Community effort - open for participation
A collaborative project was established under the umbrella of GÉANT called the OpenCloudMesh project on 22 October 2015. The kick-off meeting was held in Vienna, Austria.
The project is co-managed by Peter Szegedi (GÉANT), Jakub Moscicki (CERN) and Christian Schmitz (ownCloud). This combination of project management ensures that all the major stakeholders – GÉANT National Research and Education Networks, CERN research community and ownCloud Inc. as a commercial company with its open source developers community – are equally represented in the project and the technical, management and business aspects are well-covered.
The collaborative project is fully open to any participation and in-kind contributions. Interested parties can subscribe to the mailing list at:

Project plan (Phase I.)
The project will be delivered in phases.
Phase I. aims at demonstrating the first working prototype of the OCM protocol (API v1.0 BETA) functionally working between two separate administrative ownCloud domains (i.e. between two NRENs).
DEADLINE: 18 January 2016.

| 3.3 | Prepare for a demonstration of the federated cloud sharing feature between two administrative domains, say SURFsara and Uni Münster | We are looking for volunteers with ownCloud server version v.8 or above to test the feature. Ron, SURFsara pointed out the the Federated Cloud Sharing feature does not work together with SAML/Shibboleth based authentication. This is a showstopper for a planned SURFdrive - Uni Münster demonstration. Ticket has been created: https://github.com/owncloud/core/issues/21227 ownCloud is working on a quick work-around. FCS just needs a user name. Partners to demonstrate Federated Cloud Sharing on 19 January 2016:

History
- Around early 2012, TF-Storage participants started to actively look into data storage software platforms in order to provide on-premise file-based sync&share (aka. Dropbox-like) services to their constituencies.
- Some NRENs even ventured into the development of a proof-of-concept tool called the Trusted Cloud Drive (TCD) under TERENA
- By mid 2013, ownCloud appeared to be the most promising one with a growing open-source development community behind.
- In December 2013, the GÉANT Association (formerly known as TERENA) and ownCloud Inc. made an agreement that serves to facilitate the desire of various National Research and Education Networking organisations (NRENs) to introduce services based on ownCloud technology and/or to offer the technology to their constituencies.
- As part of this collaboration effort, in January 2015, ownCloud initiated an idea (aka. OpenCloudMesh) to interconnect the individual on-premise private cloud domains at the server side in order to provide federated sharing and syncing functionality between the different administrative domains.
