Always great to see the #SWHID in the wild ⭐ Ambassador Mohammad Akhlaghi shared a new MNRAS paper detailing a rare cosmic nebula discovery.
📖 Paper: https://doi.org/10.48550/arXiv.2606.24398

@swheritage happy birthday #swhid

April 23 marks 1 year since the #SWHID became the ISO/IEC 18670 standard. @toscalix joins us to discuss its practical use cases in software integrity & compliance. https://www.softwareheritage.org/2026/04/23/one-year-swhid-iso-iec-18670-standard/ #ISO #OpenSource #SBOM

This week I ended up the 5 article series about #SWHID, the intrinsic, persistent and standardised software artifacts identifier.

Check them out:

1. What is the Best Way to Identify Software? Introducing SWHID https://toscalix.com/2026/03/10/what-is-the-best-way-to-identify-software-introducing-swhid/

2. Description of SWHID: Syntax. https://toscalix.com/2026/03/17/description-of-swhid-syntax/

3. SWHID Is An #OpenStandard, Governed Under #OpenGovernance. https://toscalix.com/2026/03/24/swhid-is-an-open-standard-governed-under-open-governance/

What's if you could ~$ git clone SWHID?

"You’d end up with git clone as a content-addressed fetch primitive rather than just a URL fetch, which is an interesting building block for reproducible builds and supply chain verification."

A nice write-up by @andrewnez on git remote helpers 👉 https://nesbitt.io/2026/03/18/git-remote-helpers.html

[...] "I just explained the syntax of SWHID, describing how their core identifier and optional qualifiers combine to uniquely reference software artifacts, as well as specific fragments within them. "

https://toscalix.com/2026/03/17/description-of-swhid-syntax/

#swhid #swidentifier #provenance #traceability #integrity #compliance

This article explains the syntax of #swhid describing how the core identifier and optional qualifiers are structured. It shows how SWHIDs can reference software artifacts such as files, directories, revisions, and releases, and how their design enables precise comparison of software.

This coming Monday Mar 2nd at 17: 00 CET I will be speaking online about Software Hash Identifier, at the CRA Mondays sessions, organised by the @orcwg at the @EclipseFdn

I will describe the relevance of intrinsic identifiers, describe #swhid, provide some use cases and discuss with the audience the relevance of identifiers such SWHID in the context of the Cyber Resilience Act.

« there are the systemic drivers:

• FAIR data mandates from funders
• Open-lab notebook movements
• Persistent Identifier (PID) expansion into every layer of research
• Preprint-to-publication workflows that treat research as a continuum

All of these point toward a future where the “unit of science” is no longer a PDF but a rich, evolving digital object grounded in data, workflows, and provenance. »

🧐 Guess what?

‣ #Guix and #Nix are designed around Persistent IDentifier (PID) for dealing with reproducible computational environments.

‣ Software Hash IDentifier (#SWHID) proposed by #SoftwareHeritage folk provides a Persistent IDentifier (PID) for source code.

Join us Oct 15: Software Heritage's Thomas Aynaud is covering the Software Hash Identifier (#SWHID)—now an ISO standard. Free seminar, hosted by the Elisa project. https://elisa.tech/event/elisa-seminar-software-hash-id-you-will-not-be-able-to-live-without-it/

I came across the following blueprint 💻 thanks to the @swheritage newsletter.

It includes a roadmap and highlights aspects for creating greater visibility for software products and publications. It outlines opportunities and challenges for strengthening findability and reusability while making #software a recognized pillar of #OpenScience

Le #SWHID permet d'éviter des problèmes du type de celui-ci (source : https://www.software.ac.uk/publication/how-cite-and-describe-software) #reproductibilite

Le #SWHID (SoftWare Heritage ID) est un identifiant pérenne qui permet d'identifier des codes sources (repos > fichiers > lignes de commande). Le SWHID facilite l'identification des codes sources utilisés, leur citation et à partir de là la #reproductibilité des expériences. Si vous souhaitez en savoir plus, #DORANum a réalisé un guide entier sur le sujet : https://doranum.fr/identifiants-perennes-pid/zoom-swhid_10_13143_3qqg-yx41/

Zoom sur SWHID a été entièrement repensée.

Blog post: What Guix could offer in computational medical environments?

French national agency for secure drug and medicine (ANSM) requires for a medical device to have unambiguous identifications:

1. reference of the product
2. reference of the maker
3. serial number

Well, through my lenses applied to software, it reads:

1. #SoftwareHeritage identifier (#SWHID)
2. #Guix

and 3. is redundant. 😁

Well, a quick summary of a 30min talk I gave past week.

Thanks my previous colleague Sam from APHP to give me the opportunity to brainstorm on this topic. 🤩
