Inheritance diagram of bw2data.backends.json.database.JSONDatabase

A data store for LCI databases. Stores each dataset in a separate file, serialized to JSON.

Instead of loading all the data at once, .load() creates a SynchronousJSONDict, which loads values on demand.

Use this backend by setting "backend":"json" in the database metadata. This is done automatically if you call .register() from this class.

filepath_intermediate()[source]#

get(code)[source]#: Get Activity proxy for this dataset

load(as_dict=False, *args, **kwargs)[source]#: Instantiate SynchronousJSONDict for this database.

register(**kwargs)[source]#: Register a database with the metadata store, using the correct value for backend, and creates database directory.

write(data, process=True)[source]#

Serialize data to disk. Most of the time, this data has already been saved to disk, so this is a no-op. The only exception is if data is a new database dictionary.

Normalizes units when found.

Parameters:: data (*) – Inventory data

backend = 'json'[source]#
