Concepts
This page shall explain the basic concepts of Catmandu
To better make use of Catmandu is helps to first understand its core concepts:
Items are the basic unit of data processing in Catmandu. Items may be read, stored, and accessed in many forms.
Importers are Catmandu packages to read items into an application. We provide importers for MARC, JSON, YAML, CSV, Excel, and other input formats. One can also import from remote sources for instance via Atom and OAI-PMH endpoints.
Fixes transforms items, massage the data into any format you like. See Fix language and Fix packages for details.
Stores are database to store your data. With database such MongoDB and ElasticSearch it becomes really, really easy to store quite complicated, deeply nested, items.
Exporters are used to transform items back into JSON, YAML, CSV, Excel or any format you like.
