a blog post on comparing overlapping SSSOM curations from two different curators, as part of @NFDI4Chem

"Rendering SSSOM ontology mappings as RDF named graphs and RDF 1.2 triple terms" https://doi.org/10.37044/osf.io/auhzg_v1

"At the GOBLIN hackathon we explored rendering it as RDF with the individual mapping as first-class object, via two complementary serializations: named graphs (TriG, modelling sssom:MappingSet) and RDF 1.2 triple terms (Turtle 1.2, modelling sssom:Mapping). We compare the design trade-offs and show they compose rather than compete." http://index.biohackrxiv.org/2026/06/16/auhzg.html

SSSOM now specifies an algorithm for hashing records (i.e., rows in a SSSOM TSV file) to support interoperability across implementations and make semantic mappings more FAIR

📖 https://mapping-commons.github.io/sssom/spec-support-hashing

Implementations are already available in SSSOM-Java and sssom-pydantic

huge thanks to @dgouttegattat for leading the development of this part of the SSSOM spec!

every wanted to put semantic mappings in SSSOM into @wikidata

now you can

biomappings is a project for predicting and curating semantic mappings between biomedical vocabularies in SSSOM

i'm working in @NFDI with researchers from other disciplines, so I recently did a full refactor of the underlying code into a new project, SSSOM Curator (https://github.com/cthoyt/sssom-curator) to make it more accessible outside of biomedicine

Here's a screen cast describing how it works:

The EBI has recently published a preprint describing OxO2, the second major version of their ontology mapping service, now based on SSSOM: https://arxiv.org/abs/2506.04286

nice to see citation of SeMRA and reuse of the comprehensive SSSOM semantic mapping datasets we produced and archived on Zenodo: https://zenodo.org/communities/biopragmatics/records?q&f=subject%3ASemantic%20Mappings

I'm currently generating cross-lingual mappings for educational resources and found a fun non-trivial negative mapping:

kim.lp:0000122 (Gymnasium) and mesh:D020446 (Fitness Centers) aren't related, because Gymnasium is one of the types of German high school

SSSOM is the perfect place to store this (curated via Biomappings: https://github.com/biopragmatics/biomappings/pull/204)

Maybe I should suggest to the #SSSOM folks that we should start charging people for the SSSOM specification? 🤔

If we apply the “IEEE rate” of $58 for 2 pages of meaningful content, we could charge at least $300 just for the part about the SSSOM/TSV format (~10 pages)! 🤑 🤑 🤑

Hey, the IEEE gets away with that, why not us?

If you are working with #SSSOM and are wondering about how you were supposed to pronounce the acronym, I’ve got you covered: incenp.org/notes/2025/sssom-pr…

(Sorry to all those who had never heard about #SSSOM until now; most likely you can safely continue to ignore it, unless you happen to be working on semantic mappings, in which case I hope it might interest you.)

I couldn't image but in one week the #TS4NFDI hands on workshop in Hannover will be already over.

I'm looking forward to discuss #ontology #mapping approaches including #SSSOM with @cthoyt , @nichtich and Nick Juty from https://fair-impact.eu/ and @bioschemas in Hannover.

There are still a handful free places. If you want to join us at the @tibhannover feel free to register via: https://www.nfdi4chem.de/event/ts4nfdi-community-hands-on-workshop/
