Research Data Service use cases – videos and more

Earlier this year, the Research Data Service team set out to interview some of our users to learn about how they manage their data, the challenges they face, and what they’d like to see from our service. We engaged a PhD student, Clarissa, who successfully carried out this survey and compiled use cases from the responses. We also engaged the University of Edinburgh Communications team to film and edit some of the user interviews in order to produce educational and promotional videos. We are now delighted to launch the first of these videos here.

In this case study video, Dr Bert Remijsen speaks about his successful experience archiving and sharing his Linguistics research data through Edinburgh DataShare, and seeing people from all corners of the world making use of the data in “unforeseeable” ways.

Over the coming weeks we will release the written case studies for internal users, and we will make the other videos also available on Media Hopper and YouTube. These will address topics including data management planning, archiving and sharing data, and adapting practices around personal data for GDPR compliance and training in Research Data Management. Staff and users will talk about the guidance and solutions provided by the Research Data Service for openly sharing data – and conversely restricting access to sensitive data – as well as supporting researchers in producing meaningful and useful Data Management Plans.

The team is also continuing to analyse the valuable input from our participants, and we are working towards implementing some of the helpful ideas they have kindly contributed.

Interning with the Research Data Service

For almost four months, I have been interning with the Research Data Service (RDS) as a project assistant. I decided to apply for the internship simply because I had received RDS support when I was developing a Research Data Management (RDM) plan for my PhD project and I also wanted to gain experience that would help me develop my professional skills. I was beyond thrilled when I was accepted!

The project I was involved in was called the Dealing With Data Use Case Videos Project. Its aim was to gain insights into the research data management (RDM) practice of data service users in all three Colleges at the University. My main role was to interview academic staff and PhD students as well as support staff about their experiences of RDM and their views on the tools available at the University such as DataStore, DataShare, DataVault and so on. The insights gathered from the interview are valuable for the RDS team to improve their services. For my personal development, interviewing the participants has helped me to gain my confidence and hone my skills which I can directly apply for my PhD research. I also enjoyed learning about different research projects beyond my field and felt inspired by the participants, particularly in how they share their data publicly to advance research on their topic. Another part of my internship (which I found most interesting) was to conduct video interviews. I had the chance to work directly with the Video Production Team of Communications and Marketing and visited their studio. This was my first experience being involved in video filming and editing.

So, my internship now has come to end, but I won’t forget this amazing experience. I was very welcomed to be part of the team, had my own desk, joined some meetings and even out for lunch and drinks! It’s been truly a pleasure to work with such a great team and I can’t thank the RDS team enough for the opportunity to learn so much about the RDS and to extend my knowledge about RDM.

The Edinburgh DataShare Awards!

The Research Data Service team applauds those researchers at the University of Edinburgh who share their data. We therefore decided to show our appreciation by presenting awards to our most successful depositors, as part of the Dealing With Data conference. The prizes themselves do not come with a cash research grant attached unfortunately. However, the winners did receive a certificate bearing an image of our mascot for the day, Databot. We think you’ll agree the winning depositors and their data demonstrate the diversity of our collections, in terms of subject matter, formats and sheer size. We were particularly pleased with the reactions from both the recipients and the attendees, both in person, by email and on twitter (#UoEData was the Dealing with Data hashtag). Who doesn’t love the drama of an awards ceremony! A video is available.

The winners in full…

MOST DATASHARING SCHOOL: Edinburgh Medical School

– the School which boasts the greatest number of Edinburgh DataShare Collections currently. Thirty-three eligible Collections (already containing at least one dataset) such as “Connectomic analysis of motor units in the mouse fourth deep lumbrical muscle”, the Edinburgh Imaging “Image Library” and “Generation Scotland”.

MOST PROLIFIC DATASHARER: Professor Richard Baldock
– the most prolific depositor into Edinburgh DataShare for the academic year 2016-17, and over the lifetime of the repository, having shared a grand total of 1,105 data items with full metadata. These are grouped together into numerous Collections under the heading of “e-Mouse Atlas”. The majority of these detailed images show microscope slides of stained tissue, others are 3D models. They accompany a book and website published by Professor Baldock, building on the seminal work of Professor Matt Kaufman in developmental biology. The metadata for each of the slides links to a lower definition version within the e-Mouse Atlas website, where the data may be viewed and navigated in context. The original slides themselves are held by the University’s Centre for Research Collections.

MOST PROLIFIC DATASHARER (CSE): Professor Euan Brechin
– the depositor of the greatest number of Edinburgh DataShare items from the College of Science and Engineering in academic year 2016-2017. Euan deposits his coordination chemistry research data so frequently that we set up a Collection template on the Brechin Research Group, which automatically pre-populates some of the metadata fields for him, saving Euan time. If only we could find a way to mention metallosupramolecular cubes here.

MOST PROLIFIC DATASHARER (CAHSS): Dr Andrea Martin
– the depositor of the greatest number of Edinburgh DataShare items from the College of Arts, Humanities and Social Sciences in academic year 2016-2017. Some of these “Language Cognition and Communication” data items are still under temporary embargo. Users may nonetheless see all the metadata.

MOST POPULAR SHARED DATA: Professor Peter Sandercock
– the depositor of the Edinburgh DataShare item which has attracted the greatest number of page views over the lifetime of the repository: “International Stroke Trial database (version 2)” (aka IST-1).  These data from the International Stroke Trial provide a great example of how clinical trial data may be anonymised to allow them to be shared. For more information, you may want to watch Prof Sandercock’s very accessible and detailed  public lecture. Admittedly, one other item is higher up DataShare’s table of page views than IST. However we believe the traffic drawn by “RCrO3-xNx ChemComm 2016” to be artifactual, arising from the appearance of the word ‘doping’ in its abstract, and the fact the deposit was made at a time when doping in sport was very prominent in the news media. Additionally, the earlier, superseded, version of the IST-1 dataset also appears in the all-time top ten, and if we combine the number of views, it is in the No.1 spot outright 🙂

MOST POPULAR DATA 2016-17: Dr. Junichi Yamagishi
– the depositor of the Edinburgh DataShare item which has attracted the greatest number of page views (1,720 to be precise, as counted by Google Analytics) over the academic year 2016-17: “Automatic Speaker Verification Spoofing and Countermeasures Challenge (ASVspoof 2015) Database”. Here’s the suggested citation, which DataShare compiles automatically, and displays prominently, to encourage users to cite the data:

Wu, Zhizheng; Kinnunen, Tomi; Evans, Nicholas; Yamagishi, Junichi. (2015). Automatic Speaker Verification Spoofing and Countermeasures Challenge (ASVspoof 2015) Database, [dataset]. University of Edinburgh. The Centre for Speech Technology Research (CSTR). http://dx.doi.org/10.7488/ds/298.

MOST POPULAR DATA 2016-17 (CAHSS): Professor Miles Glendinning

– the depositor of the Edinburgh DataShare item from the College of Arts, Humanities and Social Sciences which has attracted the greatest number of page views (1,374 to be precise, as counted by Google Analytics), over the academic year 2016-17: “Hong Kong Public Housing Archive”. The Research Data Service is working closely with Miles, Personal Chair of Architectural Conservation, on a series of batch imports to put his fabulous array of photographs of public housing tower blocks from all around the world on DataShare over the coming months – keep an eye on DOCOMOMO International Mass Housing Archive.

MOST POPULAR DATA 2016-17 (MVM): Dr. Tom Pennycott
– the depositor of the Edinburgh DataShare Collection page from the College of Medicine and Veterinary Medicine which has attracted the greatest number of page views over the academic year 2016-17: “Diseases of Wild Birds”. Hundreds of grotesquely beautiful photographs of dead wild birds, bodies ravaged with viruses, bacteria and protists, found at locations all around the United Kingdom; these images support the PhD thesis of Dr Tom Pennycott from our Veterinary School.

DataShare 3.0: The ‘Download Release’ means deposits up to 100 GB

With the DataShare 3.0 release, completed on 6 October, 2017, the data repository can manage data items of 100 GB. This means a single dataset of up to 100 GB can be cited with a single DOI, viewed at a single URL, and downloaded through the browser with a single click of our big red “Download all files” button. We’re not saying the system cannot handle datasets larger than this, but 100 GB is what we’ve tested for, and can offer with confidence. This release joins up the DSpace asset store to our managed filestore space (DataStore) making this milestone release possible.

How to deposit up to 100 GB

In practice, what this means for users is:

– You can still upload up to 20 GB of data files as part of a single deposit via our web submission form.

– For sets of files over 20 GB, depositors may contact the Research Data Service team on data-support@ed.ac.uk to arrange a batch import. The key improvement in this step is that all the files can be in a single deposit, displayed together on one page with their descriptive metadata, rather than split up into five separate deposits.

Users of DataShare can now also benefit from MD5 integrity checking

The MD5 checksum of every file in DataShare is displayed (on the Full Item view), including historic deposits. This allows users downloading files to check their integrity.

For example, suppose I download Professor Richard Ribchester’s fluorescence microscopy of the neuromuscular junction from http://datashare.is.ed.ac.uk/handle/10283/2749. N.B. the “Download all files” button in this release works differently than before. And one of the differences which users will see is that the zip file it downloads is now named with the two numbers from the deposit’s handle identifier, separated by an underscore instead of a forward slash. So I’ve downloaded the file “DS_10283_2749.zip”.

I want to ensure there was no glitch in the download – I want to know the file I’ve downloaded is identical to the one in the repository. So, I do the following:

  • Click on “Show full item record”.
  • Scroll down to the red button labelled “Download all files”, where I see “zip file MD5 Checksum: a77048c58a46347499827ce6fe855127” (see screenshot). I copy the checksum (highlighted in yellow).

    DataShare displays MD5 checksum hash

  • On my PC, I generate the MD5 checksum hash of the downloaded copy, and then I check that the hash on DataShare matches. There are a number of free tools available for this task: I could use the Windows command line, or I could use an MD5 utility such as the free “MD5 and SHA Checksum Utility”. In the case of the Checksum Utility, I do this as follows:
    • I paste the hash I copied from DataShare into the desktop utility (ignoring the fact the program confusingly displays the checksum hashes all in upper case).
    • I click the “Verify” button.

In this case they are identical – I have a match. I’ve confirmed the integrity of the file I downloaded.

The MD5 checksum hashes match each other.

More confidence in request-a-copy for embargoed files

Another improvement we’ve made is to give depositors confidence in the request-a-copy feature. If the files in your deposit are under temporary embargo, they will not be available for users to download directly. However, users can send you a request for the files through DataShare, which you’ll receive via email, as described in an earlier blogpost. If you then agree to the request using the form and the “Send” button in DataShare, the system will attempt to email the files to the user. However, as we all know, some files are too large for email servers.

If the email server refuses to send the email message because the attachment is too large, DataShare 3.0 will immediately display an error message for you in the browser saying “File too large”. Thus allowing you to make alternative arrangements to get those files to the user. Otherwise, the system moves on to offer you a chance to change the permissions on the file to open access. So, if you see no error after clicking “Send”, you’ll have peace of mind the files have been sent successfully.
