Really excited to share that we’ve published Thoth Open Metadata’s self-assessment against the Principles of Open Scholarly Infrastructure (POSI). 🎉
For us, this is more than a compliance exercise. It’s an open reflection on how we believe open metadata for books should be governed, sustained, and shared - with community oversight, open-source code, and CC0 data and open APIs at its core. As open access policies evolve, infrastructure transparency matters for publishers, librarians, and policymakers alike. 📚 #MetadataMatters
This work connects directly to the next phase of Thoth’s development - and we’ll be continuing the conversation at the Copim community's #CopimConference tomorrow and on Friday, where we’ll be discussing the future of #communityled #OAbooks and the infrastructure they depend on together with like-minded #openinfras, #libraries, #publishers, and #researchers.
There's no #OpenAccess without #OpenInfrastructure!

With this post, we share the results of our recently-conducted self-assessment of Thoth Open Metadata against the current version v2.0 of the Principles of Open Scholarly Infrastructure (POSI). POSI is an important reference point for us: it articulates important elements of what it means for an infrastructure to be open, community-governed, and sustainable over the long term.
I’ve been documenting this for months (since 28.09.2025). Here’s a quick breakdown of how http://Amazon.de has mishandled Tom Hiddleston’s metadata for over a decade!

We are super excited to announce the publication of our substantive report "International Metadata Recommendations and Platform-Specific Requirements for #OABooks and Chapters"
The report addresses a longstanding challenge in #OAbooks publishing: how to create, manage, and disseminate metadata that actually works across today’s fragmented scholarly ecosystem. #MetadataMatters
Bringing together multiple perspectives of not-for-profit #DiamondOA book publishers, librarians, and open infrastructures, the report takes a closer look at research, policy analysis, and community insight to support publishers, libraries, and aggregators working to improve the discoverability, accessibility, and sustainability of books and chapters – with a particular focus on small-to-medium-sized, scholar-led and institutional publishers.

We are pleased to announce the publication of “International Metadata Recommendations and Platform-Specific Requirements for Open Access Books and Chapters”, …
