Dear,

I'm working on a project for the members of our ecosystem to signal/advertise dataset and ICT services they are making available to the public.
The description of the dataset and services are done in RDF and encapsulated in a verifiable credential. (W3C VC)

So far, we've build a kind of pub/sub service based on a centralised database to signal the availability of those verifiable credentials and I'm wondering if we could entirely switch to nanopublication.

Are there limits in terms of rate limiting when publishing, rule for data curation, can we publish anything, are there retention rules a server should follow ?

Best regards,
Pierre

Hi Pierre,

Interesting use case! Yes, I think nanopublications could in principle
be used for this. I don't know the details of Verifiable Credentials,
but I don't see how they could be incompatible.

There are no rate restrictions currently, but the current nanopub
servers will be replaced soon by the Nanopub Registry (currently in
development: https://github.com/knowledgepixels/nanopub-registry), and
with the Nanopub Registry per-user quotas are applied. All currently
published nanopublications will be taken over, so there is no reason to
wait with publishing though.

The basic idea of the server network is that nanopublications are stored
redundantly at several servers, which replicate each others' content. So
these nanopublications should remain available as long as the network
survives, even if individual servers come and go.

Data curation is possible - you can currently dis-/approve and review in
different forms - but happens *after* publishing.

In general you should feel free to go ahead and publish stuff, and you
don't need to worry that your nanopublications might contain errors. To
indicate that a nanopublication is just a test and shouldn't be taken
seriously, you can add this triple to the pubinfo graph:

NP a <http://purl.org/nanopub/x/ExampleNanopub>

I hope that answers some of your questions. Happy to answer more or give
you more detailed guidance.

btw, we will be organizing a nanopublication tutorial at ESWC this year
(https://2025.eswc-conferences.org/), so maybe you want to consider
joining it. And in either case, we will create the tutorial material in
the next few months, which we will make available as soon as we have it.

Regards,
Tobias
