"Virtual Folder" provides a unified access mechanism to files stored in a variety of locations including the local file system, and B2DROP and other cloud storage facilities. It is developed in work package WP6 by the West-Life H2020 project, which is running from 2015 to 2018. It provides application level services usable for structural biology use cases and follows the structural biology data lifecycle. Data management work package WP6 build on existing infrastructure for storing and accessing data to create a "Virtual Folder".
Virtual Folder can be installed: 1. from source codes 2. from binaries at cernvm-fs 3. from cloud template, contextualized to binaries at cernvm-fs
For all the installation options follow: Installation guide.
Recommended configuration for private deployment of virtual machine with Virtual Folder:
Minimal: 1 CPU, 2 GB RAM, 50GB disk space.
Recommended: 4 CPU, 8 GB RAM, 100 GB disk space
Desktop, Server OS: Windows (tested on Windows 7, Windows 2012), Linux (tested on Ubuntu 14.04 LTS, Ubuntu 16.04 LTS), VirtualBox 5.1.6+, Vagrant 1.8.6+
Cloud OS: OpenNebula, OpenStack, or any other supporting OVA images.
git clone https://github.com/h2020-westlife-eu/west-life-wp6cd west-life-wp6vagrant up
The new virtual machine can be accessed via web browser
http://[vm.ip.address]:[port]/ By default,
http://localhost:8080 Virtual folder provides WEBDAV API at
Inside VM, the files of the current working directory of host are mounted into
/vagrant and the repositories of virtual folder are accessible at
The functionality of the Virtual Folder can be integrated into other portal or web application. The recommended method is to link the existing component using cross-document messaging mechanism - e.g. for picking a file from Virtual Folder by using the File Picker component.
Follow Integration guide for further details.
In order to test, contribute to source codes and prepare virtual machine environment with source codes, follow Virtual Machines chapter.
