OpenFIGI.com provides direct access to multiple tools for identifying, mapping and requesting free and open symbology datasets. The website enables users to search the available Open Symbology data, access news and updates related to the FIGI, and obtain the OpenFIGI API specification. The website also provides powerful search criteria including access to increased coverage, the inclusion of additional fields, such as Share Class FIGI, and options to narrow down and pinpoint the results, which can be exported to Excel files without usage restrictions. Bloomberg’s Open Symbology team will also use the site to share its subject-matter expertise about symbology, data quality, data governance, metadata and ontology.
