The ODIN project will be part of the Open Repositories 2014 Conference in Helsinki:

Panel: Promoting Interoperability and Services Through Shared Identifiers

P7B: Parallel session 7B
Time: Thursday, 12/Jun/2014 11:15am-12:30pm
Location: Paasitorni – Siltasaari Hall


Persistent identifiers are stable references to digital objects, complementing traditional bibliographic identifiers in scope and level of granularity and allowing simple and traceable citations. Examples of successful persistent identifiers are URNs, Handle/DOIs, ARKs or PURLs.

Using the same approach, different initiatives have been launched to provide persistent identifiers for authors and contributors, in particular to distinguish between non-unique or variants of personal names. ORCiD, ResearcherID, and ISNI are examples of such initiatives.

In an open research environment, publications, research data and other scholarly outputs are shared to facilitate future reuse and reinterpretation. However, it is difficult to track the sharing and the re-use of such materials and to grant the appropriate credit to the original authors. An interoperable framework of persistent identifiers shared among systems would facilitate re-use, acknowledgement of credit, and the creation of diverse third-party services on an interdisciplinary and global scale.

To address these issues, stakeholder organizations have started to collaborate through projects such as ODIN to define core open infrastructure and workflows, tested through proofs of concept, and exposed through community guidelines. While substantial progress has been made, there are still challenges to overcome, including disciplinary requirements and engagement of the researchers themselves in using the identifiers and data-sharing tools. One demanding domain is data publication, which involves new forms of citation, questions on how authorship should be treated, and lack of standards for crediting researchers who share their data.

The panelists will discuss projects underway to test the use of shared persistent identifiers to support interoperability between research systems, how such interoperability affects data sharing and citation, and how it can serve as a springboard for new services. Speakers from ORCID and DataCite will discuss implementation challenges for persistent identifier registries, including community engagement and support for development of third-party services. Dryad and CERN will focus on the challenges and opportunities for integrating shared persistent identifiers.


Laura Paglione (ORCiD, Technical Director)

ORCiD ( is an open, non-profit, community-driven effort to create and maintain a registry of unique researcher identifiers and a transparent method of linking research activities and outputs to these identifiers. The initiative reaches across disciplines, research sectors and national boundaries. ORCiD provides two core functions: a registry to obtain a unique identifier and manage a record of activities, and APIs that support system-to-system communication and authentication. ORCiD makes its code available under an open source license, and will post an annual public data file under a CC0 waiver for free download.

Sebastian Peters (DataCite, Technical Team)

DataCite ( is an international organisation, which aims to establish easier access to research data, increase acceptance of research data as legitimate contributions in the scholarly record, and to support data archiving to permit results to be verified and re-purposed for future study. The primary means of establishing easier access to research data is by DataCite members assigning digital object identifiers (DOIs) to data sets. DataCite takes an open approach to identifiers, however, and considers other systems and services that help forward its objectives.

Ryan Scherle (Dryad Digital Repository, Repository Architect)

The Dryad Digital Repository ( is a curated resource, built upon DSpace, that makes the data underlying scientific publications discoverable, freely reusable, and citable. Dryad provides a general-purpose home for a wide diversity of datatypes. Submission of data can be integrated with a journal’s manuscript review and publication workflow. DOIs are assigned to enable persistent tracking and citation of data and ORCiDs are being implemented as author identifiers. The repository is governed by a membership-based nonprofit organization in collaboration with university partners that contribute to research and development.

Sünje Dallmeier-Tiessen (CERN, Open Science Research Fellow)

The European Organization for Nuclear Research (CERN, is a research organization whose purpose is to probe the fundamental structure of the universe. CERN is engaged in Open Access initiatives and works on making all its scientific output available. Through the INSPIRE digital library (, collaborates with different institutions to provide the High-Energy Physics community a centralised platform where publications, data and author information is openly available. INSPIRE is currently assigning DOIs for datasets and has started to include ORCiDs for authors.

Technical Walkthrough: Interoperability and Services Through Shared Identifiers

Poster Reception
Time: Tuesday, 10/Jun/2014 6:30pm – 9:00pm
Location: Kaisa House


Shared identifier infrastructures, such as DOIs for research objects and ORCiDs for persons, can improve interoperability, allow for increased efficiency of internal processes, and facilitate the development of innovative third-party services.

DataCite and ORCID technical staff will provide a technical walkthrough to introduce developers to the current APIs.

The EC-funded ODIN project, which builds on the ORCID and DataCite initiatives to connect services and infrastructures, will fund a developer challenge in this regard.

Developers Challenge


Shared identifier infrastructures, such as DOIs for research objects and ORCiDs for research persons, can improve interoperability, allow for increased efficiency of internal processes, and facilitate the development of innovative third-party services.

This development challenge is to use the open APIs provided by DataCite and ORCiD to build an application or service based on these persistent, shared, and open identifiers.

A non-exclusive list of possible areas on which to focus:

  • Data author discovery or disambiguation
  • Tracking institutional output
  • Curation or collaboration tools
  • Linking related research objects
  • Tracking of citations or alternative metrics to data
  • Allowing personal repositories to take advantage of ID systems

Developer how-to

DataCite and ORCID technical staff will provide a technical walk-through to introduce developers to the current APIs. Technical staff will be on-hand throughout the session to answer questions and actively facilitate participant projects.


There will be no fee to participate in the challenge. ODIN will provide a prize of an iPad to the “best” project, as determined by a vote of the participating developers. The EC-funded ODIN project builds on the ORCID and DataCite initiatives to uniquely identify researchers and data sets and connect this information across multiple services and infrastructures for scholarly communication. ODIN aims to address critical open questions including referencing data objects, tracking of data use and re-use, and linking between a data object, subsets, articles, rights statements and every person involved in its life-cycle.
