Golaem Digital Asset Python API

Golaem Crowd is shipped with a SWIG generated glm.devkit Python module. The GDA Python API allows to query and manipulate the GDA file structure including creating, importing, editing and exporting a GDA file.

Including the GDA API file in a project

The GDA API can be added to a project by importing the module:

import glm.devkit as devkit

Initialize the GDA Python API

The GDA Python API is part of the Golaem Python API, which must be initialized first using:

devkit.initGolaem()

Then the GDA API can be initialized specifically:

devkit.initGda()

Uninitialize the GDA Python API

The GDA Python API must be uninitialized using:

devkit.finishGda()

After which, the Golaem Pyhton API can be uninitialized:

devkit.finishGolaem()
