ExtendedSchema(3pm)

📦 version 2.1.1, in arch rolling

💅 Lire::ExtendedSchema

Okay bestie, welcome to Lire::ExtendedSchema (that's the 3pm manual page, if you're keeping score) — the little schema gremlin that takes a base schema and goes "and what if we added more fields to literally every record?" 💖

✨ NAME ✨

Lire::ExtendedSchema — adds fields to each DLF record of a base schema. That's it, that's the whole gig. 🎀

🌸 SYNOPSIS 🌸

my $schema = Lire::DlfSchema::load_schema( 'www-robot' );
my $ext_fields = $schema->extended_fields();

Look at her. Two lines. Iconic. 💅

🦋 DESCRIPTION 🦋

So a Lire::ExtendedSchema defines a DlfSchema that adds fields to each record of a base DlfSchema. Lowkey the whole point. ✨

Where do the values of those extended fields come from? They're usually computed from values based on the values of the fields in the base DLF record. It's giving "math but make it metadata". 🧚

Now here's the tea: these values aren't written by Lire::DlfConverters — no ma'am — they're written by Lire::DlfAnalysers (or, usually, a Lire::DlfCategoriser). Like, know your role. 💀

🫶 base()

Returns the Lire::DlfSchema object for which this schema's records are an extension. Basically "who's your parent, bestie?" 💖

🔥 can_join_schema( $schema )

Returns true if $schema can be joined with this schema. 🎀

For an ExtendedSchema, this will be true only when $schema is an ExtendedSchema which shares the same same than this schema.

Ngl, that sentence is worded kinda silly — that's literally how the original page words it, so I'm not touching it. 🙈
