LEI Model in RDF (Resource Description Framework)

I herewith confirm that I read, understood and accepted the privacy policy. I hereby confirm that data which I typed and clicked might be sent to social network owners and saved and electronically processed by them.

GLEIF in partnership with data.world has made the content of the GLEIF Golden Copy Files available and accessible as linked open data in the Resource Description Framework (RDF) format, at data.world/gleif.

The semantic model for GLEIF data defined in partnership with data.world provides details of the content and structure of GLEIF Golden Copy data. This model is published as a set of RDF ontologies defining the classes, properties and relationships between the segments of the GLEIF Golden Copy files.

RDF Ontologies for the LEI:

• GLEIF Base Ontology
• Level 1 Ontology
• Level 2 Ontology
• Level 2 Parent Ontology
• Entity Legal Forms Ontology
• Registration Authorities Ontology
• Reporting Exception Ontology

The GLEIF Golden Copy files are downloaded, converted to RDF linked open data format, and made available at data.world. GLEIF data in RDF linked open data format is currently updated and refreshed on a weekly basis.

New Capabilities and Applications Enabled by GLEIF Linked Open Data

The availability of GLEIF data as linked data knowledge graph enables all users of LEI data to connect any of their applications openly. This facilitates an entirely new phase of integration and adoption of the LEI by end-users and vendors without requiring any central development by GLEIF.

Knowledge graphs in general are gaining tremendous traction for a wide variety of applications, like regulatory reporting, business intelligence, risk management, supply chain, business development, or customer/counterparty management. The availability of GLEIF LEI data on this linked open data platform will allow GLEIF to both keep pace with as well as tap into the focus on these potential business areas.

In addition, the RDF linked open data graph can be built by others using the same procedures. This presents a scalable replication strategy for providing GLEIF LEI data in the form of linked open data via third parties.

Considering the future business cases and scalability requirements which are planned to increase adoption of the LEI and to grow the LEI population, such as the verifiable LEI (vLEI), future verified identity credential validation, prefixes for millions of Unique Transaction Identifiers (UTIs), and other uses of the LEI in the digital economy, it will be extremely beneficial to provide this linked data capability to vendors, regulators, and end-users.

GLEIF Linked Open Data Revisions for LEI-CDF 3.1, RR-CDF 2.1 and Reporting Exceptions 2.1 Compatibility

New versions of the Level 1 and Level 2 data schemas and requirements have been published by GLEIF which incorporate new data elements and content in the LEI reference data model in response to further ROC guidance and policies. Because of the revisions that are incorporated in the new LEI-CDF 3.1, RR-CDF 2.1 and Reporting Exceptions 2.1 data format standards, the GLEIF ontologies that provide the semantic definitions for populating the linked open data version of the GLEIF Golden Copy datasets have been revised. This work is currently in progress and planned to be ready when the transition to the new GLEIF XML data formats occurs in 2022.
