Catman...RC::MiJ(3pm)

💖 Catmandu::Importer::MARC::MiJ 💖

okay bestie, so Catmandu::Importer::MARC::MiJ is this whole package whose entire job is importing MARC-in-JSON records 💅 like that's it, that's the gig, and it does it beautifully.

---

✨ NAME ✨

Catmandu::Importer::MARC::MiJ — the Package that imports MARC-in-JSON records 🎀 no cap.

---

🌸 SYNOPSIS 🌸

here's the vibe, straight up, no edits:

# From the command line
$ catmandu convert MARC --type MiJ --fix "marc_map('245a','title')" < /foo/bar.json

# From perl
use Catmandu;

# import records from file
my $importer = Catmandu->importer('MARC',file => '/foo/bar.json', type => 'MiJ');
my $fixer    = Catmandu->fixer("marc_map('245a','title')");

$importer->each(sub {
    my $item = shift;
    ...
});

# or using the fixer

$fixer->fix($importer)->each(sub {
    my $item = shift;
    printf "title: %s\n" , $item->{title};
});

like literally just point it at a file and let it cook 🔥

---

🦋 METHODS 🦋

• new(file => $file , fh => $fh , id => $field) — parses a file or a filehandle into a Catmandu::Iterable, periodt. and if u want, u can also hand it an id attribute that says where the system identifier (_id) field should come from — like '001' for example 👑

---

👑 INHERTED METHODS 👑

🌈 count

🌈 each(&callback)

🌈 ...

so basically every Catmandu::Importer is a Catmandu::Iterable, which means all of its methods are inherited. you get the whole family tree for free, bestie, it's giving generational wealth 💸
