Mediaflux

The VicNode Mediaflux Service can be accessed via a simple to use JAVA client information and client download here, your web browser at the  Mediaflux Desktop web page; using Java applets (Aterm); or via the SFTP protocol with third party clients.

Overview

What—Mediaflux is a data management platform for your digital assets. It is in use by a small but growing number of Victorian and Australian data collections, particularly in bioinformatics.

Why— Mediaflux is a powerful tool that can  manage any type of unstructured data, as well as structured data, and relationships between structured and unstructured data. It can be used for ingesting, storing, discovering and sharing any type of data.

The RDSI identified Mediaflux as a useful collection management system that would be useful to researchers in managing their ReDS research data. As a result, RDSI has provided each Node with an unlimited Mediaflux license to facilitate the uptake of this tool.

How—Mediaflux is installed at VicNode’s operating centre at the University of Melbourne on behalf of all Victorian researchers. It presents a simple to use JAVA client for data ingestion, collection browsing and sharing, a web browser interfaces for administrative tasks and collection browsing, as well as a simple SFTP interface for folder and file operations.

When—Now. Mediaflux is ready for use.

Making a collection accessible using Mediaflux

Once you have an approved storage allocation on VicNode, you can request that all or part of this allocation may be made accessible using the Mediaflux service by emailing VicNode Support with your request.

Each collection that has Mediaflux access exists as a unique and private Project within the Mediaflux service. Each Project has distinct ownership and membership rules on an account by account basis. The portions that a collection owner/curator chooses to make public and read-only has no default settings and as such, can be set to meet the collections specific requirements for visibility, sharing, role management, and data ingestion.

Users can login using their institutional credentials by utilizing the AAF domain (aaf) or using the VicNode domain for local server accounts.

Data can be ingested into Mediaflux several ways. Supported methods include; most web browsers for file upload and download, a Mediaflux specific desktop Java client applet or an SFTP client.

The SFTP interface allows assets within Mediaflux to appear as files in a Posix style folder and file structure. Users can access this using their favourite SFTP client such as WinSCP, CyberDuck or FileZilla.

During the ingest process, meta-data about the each asset ingested is extracted and indexed. New indexes and meta-data can be added to a collection any time.

Managing User access to collections with Roles

Mediaflux-Access-ManagmentAccess to a collection is managed by the collection owner through their account having the Project Administrator role for the project. This is set up at project creation time by VicNode staff. The Project Administrator then uses the Access Management application in the web client to grant rights to other project members. There are three additional default roles for manipulating assets ( access, access+create+modify, access+create+modify+destroy ).

The role allocation is achieved by dragging the desired role and dropping it on the intended user account. Open two Access Management application windows, in one window, browse to find the desired user. In the other window, browse to locate the role to grant to the user. Click and Drag the role and Drop it on the desired User. A confirmation window will pop-up to describe the Role being applied to the User.

The Aterm command line can also be used to achieve these functions.

Public Browsing and Download

There is a new “Portal” feature that allows users a simplified web browser interface. This does not require users to login or install Java and is ideally suited to casual users just wanting to download particular assets. This service is still under development.
