Virtual folder

Introduction

This "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.

This is part of a Virtual Research Environment for structural biology: the application level services specific to uses cases in structural biology.

This is developed 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".

Usage

A public installation of the Virtual Folder is available at West-Life portal https://portal.west-life.eu/virtualfolder Follow User's guide for further details how to use it.

Installation

Recommended configuration for private deployment of virtual machine:

  2. from binaries at cernvm-fs
  3. from cloud template, contextualized to binaries at cernvm-fs

Brief installation from sources:

git clone https://github.com/h2020-westlife-eu/west-life-wp6

cd west-life-wp6

vagrant 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 http://[vm.ip.address]:[port]/webdav e.g. http://localhost:8080/webdav
