En mi último proyecto he utilizado Wikidata y SPARQL para explorar conexiones humanas de "larga data" que escapan a los libros de historia tradicionales. Al modelar personas como nodos y relaciones (como wdt:P40 "hijo/a de") como aristas, podemos recorrer linajes enteros en milisegundos.

@harmonia_amanda the vast majority of #SPARQL experts are autodidact! Heck I learn more from the #uniprot sparql endpoint users with their user cases than from the language spec. The joy of seeing smart scientist play with the data is amazing

Should I add my #wmhack traditional catchphrase (that I've been using on my name card for like a decade now (where is time going? 😱 )) "I #SPARQL joy" to my mastodon bio?

Pro: I like it
Con: I'm not, actually, trained in SPARQL, I'm an autodidact user (and not even a tech person in general)

yes of course!
100%
no, it would be too misleading

Du coup j'ai fait mes premières requêtes #SPARQL utilisant les deux graphes depuis la séparation (ouais les articles scientifiques c'est pas trop mon trip sur #wikidata) et euh mon avis pour le moment c'est que c'est facile ???

Genre on m'en avait raconté des histoires d'horreur mais ça reste plus facile que d'aller fédérer avec un autre endpoint ?

Bon, le truc à se souvenir c'est hint:Query hint:optimizer "None" mais à part ça…

(je continue à trouver que requêter les géolocs c'est pire, voilà c'est dit)
