Flow

Indicates whether this flow describes an infrastructure product. This field is part of the openLCA schema because of backward compatibility with EcoSpold 1. It does not really have a meaning in openLCA and should not be used anymore.

Type: boolean (external doc)
Proto-Index: 14

`location`

The location of the flow. Normally the location of a flow is defined by the process location where the flow is an input or output. However, some data formats define a location as a property of a flow.

Type: Ref of Location
Proto-Index: 15

`synonyms`

A list of synonyms but packed into a single field. Best is to use semicolons as separator as commas are sometimes used in names of chemicals.

Type: string (external doc)
Proto-Index: 16
