Mediaflux

1 Overview

What — Mediaflux is a very capable, general and extensible data management platform for managing digital assets. You can read a little about it here: http://www.arcitecta.com/Products

Why - It 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 and discovering any type of data. It has a focus on discoverable rich meta-data supporting data. Mediaflux also has advanced inter-operability (so it can interact with other unlike systems) features as well as capabilities supporting big and distributed data.

How - Please read the service description that provides a high-level summary of what our service offers.

Please note that with the release of the new system (Oct 25 2018) the server name and IP has changed. However, most of the screen shots and videos in the documentation still use the old address (eventually we will update). All tables and text have been updated with the correct details.

2 Access

Mediaflux supports many protocols (e.g. HTTP, sFTP) and access mechanisms (e.g. browser based, various client applications). Please read about the access mechanisms here - these describe how to log in with both AAF (Australian Access Federation) and local accounts via the various interfaces.

3 How to work with your Project Data

Because Mediaflux is a very diverse system, it is not possible to describe everything you can do with it. Instead, we focus on some basic patterns that are relevant to managing research data. What you can do depends a bit on the interface you are using. So or approach will be to describe scenarios, and then discuss which tools are most relevant to it.

4 Spartan HPC Service Users at the University of Melbourne

Some of the data movement tools described in the upload/download links above are conveniently provided to Spartan users via the Spartan module system. Please read the details here.

5 Software Downloads

Please see this link for downloads including various client applications such as 1) the Mediaflux Explorer, 2) ATERM, 3) UoM clients for uploading and downloading data and 4) Training Videos

6 Known Issues

  • 17-Jan-2018 Issue:
    • Uploads with sFTP are sometimes resulting in incomplete assets (no content and incomplete meta-data)
      • sFTP currently disabled
      • Status: it is known sFTP uploads when the quota is reached will result in this result (and the user gets no warning/information that it has happened). There may be other use cases also.
      • Resolution: this known case is being fixed.
  • 25-Oct-2018 issue: There is an issue in the system (has been there for months) which sometimes causes the system to transiently lock out all users (and terminate your current sessions - usually you will get an SSL HandShake error if connected via HTTPS). It typically lasts for a few minutes but longer periods have been seen.
    • Status: The sever has diagnostics in it now to help us identify the cause of the issue. We have a working theory and a process to gather information if and when it occurs next time.
    • Resolution: when it is solved we will schedule a short-notice outage
    • Resolved in upgrade 18-Jan-2019

7 Service Transition

  • The service moved to new infrastructure over 25/26 Oct 2018. The transition document is here
  • The new server address is mediaflux.researchsoftware.unimelb.edu.au
  • Explorer users please use V 1.3.27 (see downloads page)
