New blog post! I've started taking regular snapshots of Library of Congress linked open data (as part of a much broader data rescue and monitoring project) and took the opportunity to finally get to grips with #SPARQL, #RDF and all that comes along with it. I've started small though...

On fooling around with triples
https://erambler.co.uk/blog/on-fooling-around-with-triples/

This week’s edition of my @linkedin newsletter shines a light on the impact of the Model Context Protocol (MCP) across multiple computing eras—leading right up to today.

We’ve arrived at a moment where loose coupling principles are cool (and super useful) again.

Naturally, there are some live demo nuggets in the post to help bring it all to life:

The Model Context Protocol acts as a universal translator between LLMs and data sources, eliminating complex platform-specific requirements. Our new open source MCP server for ODBC (mcp-odbc-server) enables seamless integration of any ODBC-accessible data into RAG pipelines.

TIL: Eine #SPARQL Abfrage in #Wikidata nach aufsteigender #QID zu sortieren ist etwas mehr, als in https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/queries/examples beschrieben. Statt bloß "ORDER BY ?horse" muss man schon zu "ORDER BY (xsd:long(STRAFTER(STR(?horse),"Q")))" greifen.

We’re excited to introduce the latest Virtuoso Maintenance Release—Virtuoso 08.03.3333—packed with feature enhancements and bug fixes across the platform.

Voilà mes interventions d'ici la fin (et un peu au delà) de ma dernière résidence #Wikimédia au sein d'une #URFIST. https://fr.wikipedia.org/wiki/Projet:Wikifier_la_science/Nice #Wikipedia #SPARQL #OpenRefine #Wikidata #WikiCommons #LicenceLibre

Looking for some #SPARQL help, as I'm a newbie to this and my mental model of how triple stores work is incomplete.

I have two versions of the same set of terms in two Turtle files, and I want to load them up into a triple store and then compare them to see what changed: terms updated, added or deleted.

I just figured out that combing markerclusters with layers in #SPARQL queries visualising results from #Wikidata on maps can give you a nice coloured classification of periodicals by publishing language.

Unfortunately the query is too long for posting it here ...

Update: created a gist for this query at https://gist.github.com/tillgrallert/3999b5da1616107a483221bc04a420c2

At @swat4hcls there was a presentation by @albdrg that I really like: https://www.youtube.com/watch?v=F4Nl-nmLZA4 This uses #SPARQL to combine data in a privacy aware #beacons-api and combine it with public #knowledgegraph like #uniprot by @SIB and #wikidata @wikidata to reduce cost of the data integration challenge required to answer clinical question.

A #SPARQL-Request: This item https://database.factgrid.de/wiki/Item:Q1194835 has the official results of the recent German elections. You can run a query on it: https://tinyurl.com/24yzfcax - but how do you add the units? - much obliged, Olaf

Yes: @cellosaurus #SPARQL endpoint is alive and ready to shine :) Please try it out at:

More #FAIR data by the @SIB

#sparql and #wikidata wizards: is there a way to create a concordance of inventory numbers (P217) for a list of items? It should also include P31 and P131, pls.

This is a more user friendly SPARQL query editor with 111 example queries.
It offers three main features: (i) automatic query example rendering, (ii) precise autocomplete based on existing triple patterns including within SERVICE clauses, and (iii) a data-aware schema visualization.
