A CatalogInterface provides basic-level semantic data about entities

Only requires the abstract ArchiveImplementation

Attribute requirements for the archive: - everything required by BasicImplementation - entities_by_type() - count_by_type() - search(), including implicitly _narrow_search()

lcia(**kwargs)

Generate LCIA Methodologies or method collections- these are specified by having the singleton MetaQuantityUnit (and/or the unitstring '0') as a unit. They should not have indicators. They have a property 'impactCategories' which is a list of included lcia_methods

Parameters:

Name	Type	Description	Default
kwargs			{}

Returns:

Type	Description

lcia_methods(**kwargs)

Generate LCIA Methods-- which are quantities that have defined indicators

Parameters:

Name	Type	Description	Default
kwargs			{}

Returns:

targets(flow_ref, direction=None, **kwargs)

Generate processes in the archive that terminate a given exchange i.e. - have the same flow and a complementary direction. If refs_only is specified, only report processes that terminate the exchange with a reference exchange.

Parameters:

Name	Type	Description	Default
flow_ref		flow, exchange, or flow's external key	required
direction		[None] filter	None

Returns:

unmatched_flows(flows, **kwargs)

Takes in a list of flows and generates a sublist of flows that were not recognized as synonyms to any local flows.

Uses TermManager.get_flowable which tries the best of flow.synonyms, flow.name, str(flow)

Parameters:

flows			required
kwargs			{}
