✨ Catmandu::Wikidata (3pm) ✨

okay bestie, sit DOWN, because this is the Catmandu::Wikidata manual page, section 3pm of the User Contributed Perl Documentation, and it's literally the glow-up your Wikidata pipeline has been waiting for 💅

---

🌸 NAME 🌸

Catmandu::Wikidata — import from Wikidata so you can process it with Catmandu 🦋

---

🎀 VERSION 🎀

version 0.06 — yes, the whole entire vibe, right there in the number ✨

---

💖 SYNOPSIS 💖

here's the group chat receipts of how you actually run it:

catmandu convert Wikidata --items Q42,P19 to JSON --pretty 1

echo Q42 | catmandu convert Wikidata to JSON --pretty 1

catmandu convert Wikidata --site enwiki --title "Emma Goldman" to JSON --pretty 1
catmandu convert Wkidata --title dewiki:Metadaten to JSON --pretty 1

catmandu convert Wikidata --title "Emma Goldman" \
    --fix "wd_language('en')" to JSON --pretty 1

(that second Wkidata line? yeah she's serving a little typo energy, but she's in the original so she stays, no cap 🫶)

🌈 DESCRIPTION 🌈

so Catmandu::Wikidata hands you a whole set of modules for processing data from <http://www.wikidata.org/> inside the Catmandu framework. it's giving very main character.

specifically, it makes it easy to get at Wikidata entity records via Catmandu::Importer::Wikidata, and then to simplify those records using fixes — that's wd_language($language), wd_simple(), wd_simple_strings(), and wd_simple_claims(). and because it's Catmandu, you can bring in other Catmandu modules to keep processing the records after that, like loading them into a database. iconic behavior honestly 🔥

👑 MODULES 👑

• Catmandu::Importer::Wikidata — imports entities from <http://www.wikidata.org/>, periodt.
• Catmandu::Fix::wd_language — limits the string values in a Wikidata entity record down to just one language you picked.
• Catmandu::Fix::wd_simple_strings — simplifies labels, descriptions, and aliases of a Wikidata entity record. so much cleaner bestie ✨
• Catmandu::Fix::wd_simple_claims — simplifies the claims of a Wikidata entity record.
• Catmandu::Fix::wd_simple — applies Catmandu::Fix::wd_simple_strings and Catmandu::Fix::wd_simple_claims. then it goes even further and simplifies sitelinks, and optionally applies Catmandu::Fix::wd_language too. the combo queen 💅
