GLEIF has an Open Data philosophy and a mission to manage a network of partners. As such, GLEIF is working with various organizations to create software to manage LEI data or help to leverage the use of LEI data. To provide transparency, GLEIF provides “open source” software to any interested party for use at their discretion. Based on the CC0 license, users are free to do anything with the provided software. Below is a list of currently available open source software repositories.

Entity Legal Form Code Assignment Tool

GLEIF, in collaboration with Sociovestix Labs has developed a machine learning tool for automated assignment of the ISO 20275 code for Entity Legal Forms (ELF Code). The solution is a python library called lenu (Legal Entity Name Understanding) developed using the Global LEI Repository as an open source labeled data set. The tool enables organizations to integrate this ISO standard into their data without requiring in-depth manual processes. This will automatically improve the data quality of their data.

The open source repository is available at:
github.com/Sociovestix/lenu

Relationship Visualization Tool

The Relationship Visualization Tool was created during a hackathon held at the GLEIF offices in July 2019, in collaboration with CorrelAid. It allows anyone to search for a legal entity and view the relationship graph, displaying the parents and children of this entity, in an easy to understand and user-friendly way.

The open source repositories (server and client) are available at:
