searchable store backed by MongoDB

 Catmandu::Store::MongoDB is a Perl package
 that can store data into MongoDB databases.
 The database as a whole is called a 'store'.
 Databases also have compartments (e.g. tables) called Catmandu::Bag-s.
 .
 Catmandu provides a suite of Perl modules
 to ease the import, storage, retrieval, export and transformation
 of metadata records.
