THOR’s last hurrah

Project THOR is coming to a close. Our final event was held in Italy on 15 November at ‘La Sapienza’ – the University of Rome – just a stone’s throw from Michelangelo’s impressive sculpture of Moses in the church of San Pietro in Vincoli. The day combined a retrospective review of THOR’s achievements and impact with a forward-looking perspective on the wider persistent identifier (PID) landscape.

With help and advice from CINECA’s Paola Gargiulo the event attracted an audience of Italian researchers from a wide range of disciplines, to join delegates from THOR partner organisations. Adam Farquhar of the British Library followed Paola’s welcome with an overview of THOR’s mission to embed PIDs within the heart of scholarly communications.

Key notes

Herbert van de Sompel, one of our two keynote speakers and Digital Library Research & Prototyping Team lead at Los Alamos National University, presented important research on maintaining the integrity of hyperlinks to managed collections such as journal repositories. ‘Link rot’ – broken links – and ‘content drift’ – where a link works but takes you to something other than the original content – are both problems, albeit less so than for the web at large. Solutions suggested for the scholarly web included using metadata that describes the relationships between links using resources such as

Our second keynote talk was given by Fiona Murphy, an independent research data and publishing consultant and excellent THOR Ambassador. She has been considering the question of what scholarship would look like had it been digital from inception, with PIDs integral to the process. The Matrix of the Commons – found at – is the result of work on how to get us from here to there, via a guiding set of decision trees on how to treat a range of digital entities appropriately and consistently. Important take home messages were that we should all assume 1) that our tools will be used in conjunction with other systems and 2) that they should be built for drivers, not mechanics.

THOR round-up

Between keynote talks, THOR partners presented highlights from the project deliverables over the course of two sessions. In the first, Maaike Duine (ORCID) summarised THOR’s communications activities and Ambassador programme. Elizabeth Hull presented DRYAD’s perspective on linking data and publications. Martin Fenner (DataCite) looked at claiming workflows to ORCID. Robin Dasler spoke both about analysis preservation at CERN and THOR’s analyses of PID service adoption. Robert Petryszak (EMBL-EBI) talked on how to realise the full potential of PIDs in the biosciences, and the session closed with a demo of dynamic data identification in the earth and environmental sciences from Markus Stocker (PANGAEA).

After lunch, Tom Demeranville (ORCID) gave updates on developing tools for federated identity management and better use of organisation identifiers. Martin Fenner returned to share outcomes from a joint THOR-OpenAIRE workshop on article-data linking. Angela Dappert (British Library) considered the challenges of embedding persistent identifier services within the humanities. Sünje Dallmeier-Tiessen (CERN) fed back from a high-energy physics community workshop. Lastly, Maaike Duine reported on insights gathered from a focus group meeting to envision the ‘ideal PID world’ for publishing workflows.

Points for discussion

It wouldn’t have been a THOR event without the opportunity for everyone to participate, and the mid-afternoon panel session provided a dedicated forum. Panellists Hannah Hope (Wellcome Trust), Clifford Tatum (CWTS), Andres Mori (Digital Sciences), Erika Bilicsi (Library and Information Centre of the Hungarian Academy of Sciences) and chair Adam Farquhar addressed comments and questions from the room.

Discussion points included the relative underuse of funder IDs, identifying a current difficulty in capturing full information for works involving multiple funders as a possible stumbling block. A question on how best to approach differences of opinion, e.g. between co-authors faced with article- or data-retraction, provided useful food for thought. Changing our general view was suggested as a potential way forward given that not all retractions are equal and the reasons may well be mundane, rather than issues of capability. Also covered were the concepts of PIDs as a compromise between the readability needs of human and machine, and of the importance of working out which features of an object are the most critical to identify.

Important take-homes from the day were that PID space is developing at an active and encouraging pace and that we should stay alert to idea that, in terms of policy, one size may not fit all.

Finally, Simon Lambert (STFC) looked ahead to the FREYA project, which will follow on from THOR, starting on 1 December 2017. One of its key strands is to achieve long-term sustainability for the outstanding progress and development that began with ODIN – THOR’s predecessor – and advanced significantly during the 30 months of THOR.

Research Graph & VIVO Interoperability enabled by persistent identifiers

In the Research Graph project, we are connecting research data to publications, grants and researcher profiles. The core component is the Switchboard software [1] by the Research Data Alliance DDRI working group, and now this system has a new capability to exchange data with the VIVO platform. The group has received significant input from Dryad, DataCite, CERN, ANDS and other THOR project partners.

At the Open Access Repository Conference (OR2017), Dr. Mike Conlon — director of the VIVO project — presented the interoperability between VIVO Ontology and the Research Graph data model. In his presentation [2], Mike demonstrated how the VIVO software can be used to provide researchers with a highly accessible interface to explore collaboration networks derived from the Research Graph network of scholarly works.

VIVO [3] originated at Cornell University and was developed as an open source enterprise system with funding by the US National Institutes of Health 2009-2012.  VIVO uses a collection of ontologies, including the VIVO Integrated Semantic Framework (VIVO-ISF [4]) to represent scholarship, and it is in use at more than 150 sites in 26 countries.  

The adoption of ORCID iDs and DOIs has been a key enabler for this project and connecting publications and researchers using these identifiers has empowered us to link records across systems with heterogeneous metadata. Furthermore, we are working on finding a comparable approach for the grant records. Crossref Funder Registry provided us with a method of connecting funder records; however, there is a gap in the sector for the grant identifier.

The interoperability between the Research Graph and VIVO can result in a network of open access scholarly communication, and it can lead to large-scale, open, linked data that would support research discovery.

ORCID at Leiden University

This guest blog post has been written by Mieneke van der Salm, Information Specialist at Leiden University Libraries in the Netherlands and has been cross-posted from The Connected Leiden Researcher.

On June 22, Leiden University Libraries (UBL) organised an information session on the Open Researcher and Contributor Identifier (ORCID) and its benefits and uses. The event was held to kick off the campaign to get as many Leiden researchers as possible to claim their ORCID iD and to add it to our local research information system, LUCRIS.

The speakers were Maaike Duine, THOR Training and events officer at ORCID, Matthew Buys, ORCID’s Regional Director EMEA, Peter Verhaar, the UBL’s ORCID implementation project team leader, and Mieneke van der Salm, ORCID implementation project team member and author of this blog post. We had about 18 people in attendance and what was particularly encouraging was that those present represented a broad range of academia, including staff from the Faculties of Law, Social and Behavioural Sciences, Medicine, Sciences, and Humanities.

The afternoon started off with Peter giving an introduction on ORCID and what the current possibilities are in Leiden. He explained briefly why ORCID was necessary and how it has become an increasingly standard pillar in the scholarly infrastructure. ORCID is steadily being integrated in the information flows of funders, publishers, and research institutions. Working from the credo “Enter Once, Reuse Often” ORCID can be used to link an author to their work from manuscript submission to registration in their institution’s research information system. An example of how such a work flow might look can be seen in Peter’s slide on the crossref auto-updater. Peter also explained how linking your ORCID iD to the Leiden University research information system (LUCRIS) will allow you to easily update the CRIS with newly published works through ORCID.

This last thing is also one of the main objectives of the ORCID implementation project at Leiden University. We want to stimulate authors to claim their ORCID iD and to register it in LUCRIS. Next to the fact that it makes an important contribution to the central goals of Open Science, it will also allow Leiden University to have a more complete coverage of Leiden research and publications in our CRIS. Our project has currently landed in the phase of raising awareness and together with our student assistant we hope to be able to reach out to all of our Leiden researchers and help them claim an ORCID iD and link it to the CRIS. An additional benefit to linking your ORCID id to LUCRIS is that it will allow you to login into ORCID with your institutional account, which means you don’t have to remember yet another password.

After Peter concluded his introduction, Maaike Duine explained more about persistent identifiers (PIDs) in general and the work of Project THOR in particular. THOR stands for Technical and Human Infrastructure for Open Research. It aims to make PIDs more pervasive in the research cycle and familiarise researchers with their uses. Funded under Horizon2020, THOR has numerous partners, both non-profit and commercial. One of the products they’ve created is the THOR Knowledge Hub, which gives a great overview of all available PIDs and their possible uses. They’ve also created a THOR Dashboard which shows the adoption of the various PIDs during the project’s existence, which shows the steady increase of their usage. But it also showed that growth across global regions is uneven and that not all disciplines are represented equally.

After Maaike had given us an overview of Project THOR, Matthew Buys went into more depth about ORCID, its properties and applications. He broke down the problems ORCID aims to solve and explained how. He showed how ORCID makes information more dependable through authentication, and that the system collects, displays, connects, and synchronises data across different information systems.

After Matthew’s in-depth presentation on ORCID, it was my turn to conclude the session with a discussion where I turned the tables and asked our audience a question: how would they suggest we would best be able to reach their colleagues and convince them to claim their ORCID iD if they haven’t yet? The suggestions ranged from organising lunch meetings, to visiting research groups, giving practical suggestions on how to fill your ORCID quickly with all your publications instead of having to manually enter all of them, to just being where the researchers are.

The questions that were asked of us often had to do with privacy and what happened with all the data that ORCID collected. As far as privacy is concerned, the answer is simple; it is all in your control. From your settings you can control who can view your information, who can update your record and rescind that permission at any time

All in all, it was an interesting gathering that provided us with a lot of food for thought on how to better serve our researchers. While we already offer support in the form of practical help with registration, whether via email, phone or in person, we certainly hope to be able to extend the integration of ORCID into our systems in the coming months.

Release Note for the THOR Dashboard

Following the release of the THOR dashboard last year, conversations with internal users, stakeholders and even the project’s reviewers have highlighted additional data and features that might serve to make the dashboard more comprehensive for the wider PID community. At the same time, available resources have changed, and THOR’s own interests have evolved as the project has progressed. In light of all this, we’ve performed a series of updates to the dashboard during the second year of THOR.

A report released today outlines these updates, as well as our considerations during the process and how others can potentially benefit from the dashboard work. The most visible update is the inclusions of some basic measures from Crossref, but a number of operational improvements were made behind the scenes to improve the scalability and robustness of the dashboard. The report also highlights challenges and lessons learnt throughout the process of developing and maintaining the dashboard. These include design limitations and our experiences of designing tutorials to instruct others in creating similar services, as well as the common issue of scope creep.

It is our hope that others can follow our work on the THOR dashboard to develop other useful services for the PID community. Our experience with the dashboard indicates that there is still quite a way to go in pursuit of comprehensive PID metrics, but THOR is making big strides along this path.

The dashboard is available to view on the THOR project website.

Fostering Synergies Among Research Projects: THOR and ENVRIplus

Earlier this year, the H2020 projects THOR and ENVRIplus joined forces and organised a bootcamp focusing on integrating ORCID in environmental research infrastructures. The bootcamp was inspired by the ORCID integrations carried out by THOR partners earlier in the project.

Persistent identifiers, including ORCID iDs, are important elements of any research infrastructure. They are used to identify data, people and other entities persistently and unambiguously, such as instruments, platforms, and deployments. Most of the 20+ infrastructures represented at the bootcamp indicated that pursuing ORCID integration is urgent.

This led to great news for THOR: the topic of ORCID integrations in environmental research infrastructures and, specifically, ORCID integrations guided by the ENVRI Reference Model, was selected as a highlight in the recent ENVRIplus Mid-Term Review.

The Reference Model describes the ‘archetypical’ environmental research infrastructure from key viewpoints and serves as a common framework and specification for the description and characterisation of infrastructures. It specifies ORCID’s role in relation to research infrastructures, the required computational components and how they integrate with ORCID, and clarifies that the ORCID iD is an information object manipulated by infrastructures.  

The highlight was a direct result of the THOR-ENVRIplus bootcamp, drawing on discussions raised during the bootcamp and ongoing developments since. We think this result underscores the potential of knowledge exchange between H2020 projects. By developing PID infrastructure, THOR results offer state-of-the-art technology to research infrastructures as well as expertise on techniques and approaches. Conversely, ENVRIplus and partner infrastructures can present platforms with challenging real-world problems in which THOR, and the PID community more generally, can ground their research and development results.

We look forward to continued active exploration and exploitation of synergies between the PID community and research infrastructures, be it in earth and environmental sciences or other domains, or between THOR, ENVRIplus as well as other projects.

THOR Bootcamp in Budapest


We are happy to announce that the THOR Bootcamp tour bus is on its way to Budapest!

On September 28 and 29th, the next and final event of the series will be hosted in collaboration with our friends at the Library of the Hungarian Academy of Sciences (DataCite member and ORCID integrator), taking place on its campus by the bank of river Danube, overlooking the magnificent Széchenyi Chain Bridge.

We are excited to bring our work and expertise on interoperable research to the scholarly community in Hungary. The Bootcamp format is designed to bring a mixed audience together, provide an open forum where librarians, research funders and publishers, service providers and developers can discuss the role of PIDs in scholarly communication, consolidate PID use cases, share PID service adoption experiences and explore integration and application possibilities.

THOR aims to transfer knowledge, boost adoption and support PID related strategic planning and technical integration with practical guidance through the Bootcamp series. As usual, we will take the community response to our registration questionnaire into consideration, and tailor the content for you – we intend to have you armed to the teeth with the PID knowledge and tools you need by the end of the Bootcamp!

Sign up here,  see you there!
