Guides to Choosing Persistent Identifiers - your feedback wanted!

The FREYA Project team is pleased to announce the publication of our initial guides on choosing persistent identifiers for different entities and we would like your feedback.

Published on Zenodo, these short guides were created to help with choosing persistent identifiers for various types of entities.
While not intended to be fully comprehensive, they are designed to provide a starting point for anyone thinking about using persistent identifiers in their systems. We created guides for the following entities:

  • Publications
  • Datasets
  • People
  • Organizations
  • Software

A table summarising all of the guides is also available.

We would value feedback and comments on these first versions throughout June 2020. You can provide feedback in the comments below or via email through info@project-freya.eu. Revised versions will be developed in July 2020.

Dear Frances,

Thank you for sharing these guides :slightly_smiling_face:

Some feedback about the People identifiers guide:

Page 1. The second branch of the tree “To identify individuals within my systems” only mentions ISNI, but actually ORCID can be (and is) used for this purpose. Integrating ORCID iDs and APIs in local systems can help solve the name ambiguity issue and supports interoperability.

Page 2. ORCID Format. The canonical form of the ORCID iD: https://orcid.org/0000-0002-1825-0097. More info under https://support.orcid.org/hc/en-us/articles/360006897674-Structure-of-the-ORCID-Identifier

I hope this helps!

Regards,
Gabi

These are great! Just shared on Twitter :slight_smile:

Hey Gabi, Re: point 1 - absolutely - the euroCROS/OCLC survey of research information systems found that 73% of the organisations that they surveyed used ORCIDs, and the majority of those will be using the API. See https://doi.org/10.25333/BGFG-D241 for details.
Cheers,

Thanks for your comment, Josh!

Dear all, thank you for this guide.
I would like to suggest a few necessary add-ons to Publication identifiers.
ISSN has been used since its inception to identify proceedings, journal titles and more recently blogs.
One can easily find these various types of continuing resources on the ISSN portal easily (portal.issn.org).
ISSN is interoperable and cross-check data with CrossRef and Wikidata but also with a variety of information providers.
The ISSN portal also provides free metadata which is sufficient to identify titles. For subscribers, the ISSN portal provides reliable and up-to-date full metadata.
Access and searching are regular features of the ISSN portal for both humans and machines, thanks to our API. The ISSN Portal also provides information in linked data formats.
Moreover, all ISSN are embedded in URIs as described in ISO 3297 standard. ISSN URIs have the following syntax: https://portal.issn.org/resource/ISSN/0376-4583. This feature allows external databases to directly link to the page containing metadata.
Moreover, on the second page of the guide regarding Publication identifiers, these identifiers should be introduced in alphabetical order.

Thank you for amending this guide accordingly.
All the best,

Gaelle Bequet, ISSN IC Director

These guides look really helpful and we will definitely be using them at Imperial, thank you!

One comment, on the publication guide there is only reference to Crossref DOIs. Is it possible to include reference to DataCite or other DOIs that organisations (such as us) are using for publications?

Kind regards
Robyn Price (Imperial College London)

Dear Frances, Hope this finds you well. Any reaction to my comments? Would be much appreciated. All the best, Gaelle

Hi Gaelle
Thanks to you and others for your useful comments. We will be reviewing all the comments received together in a few weeks and hope to publish new versions before the end of the summer.
If we have any queries about any of your suggestions we will be in touch.
Thanks again!
Frances

Hi Frances, many thanks for the update. Do not hesitate to contact me. All my best. Gaelle

Thanks for compiling these, very useful overviews! I like that they are written from the perspective of what functionality is conveyed by identifiers to the objects.

From the perspective of the actors choosing identifiers, it might be useful to include, in addition, characteristics as to costs of using the identifiers (if any), and perhaps also governance and business model of the organizations providing the identifiers (as is included for organization identifiers)

In general, I find the tables more neutral than the decision trees, which inevitable have some subjectivity in them e.g. in the order in which choices are presented (that could lead to other outcomes than when all parameters are presented without hierarchy).

A couple of other comments and questions , focusing on IDs for publications:

  • “journal articles” instead of journals?
  • for books/journal titles, checkmarks for ISBNs/ISSNs in the blue columns
  • is there a specific reason handles have a checkmark for persistent linking and DOIs don’t?
  • Crossref DOIs are specified, but Datacite DOIs are also used for text material (eg. for preprints at Zenodo and Figshare, and in some institutional repositories) (and there are other, sometimes country-specific DOI registries as well)

I also second the comments made above about ORCIDs as identifiers within institutional systems.

Finally, I would be interested whether people working on Wikidata would have any suggestions for additions in the tables.

Looking forward to the next iteration!

Thanks so much for all the comments on these guides. We really appreciate the time taken with this considered feedback.

We are starting to work on revising them now and look forward to sharing new versions with you soon. :grinning:
