Public users of LEI data are reminded that from March 1, 2022, all GLEIF services will accept and display data in updated Common Data File (CDF) formats, requiring users to implement these new file formats ahead of that deadline for uninterrupted access to LEI data. The updated file formats will increase the level of open, standardized, and high-quality legal entity reference data available within the Global LEI Index.

The CDF formats define how LEI issuing organizations report their LEI and reference data. GLEIF published updates to the formats in 2021 to align with the following new ROC policies:

Throughout the month of March, all LEI issuing organizations will migrate to the new formats and undergo testing to ensure a smooth transition. Users of the Global LEI System should therefore be prepared to support content following the existing and new business rules throughout March when performing LEI data analysis. This applies to users of the following LEI data:

  • GLEIF Concatenated files
  • Golden Copy and Delta files
  • Golden Copy files accessed via the GLEIF API

Data consumers can make their updates to the new format versions in advance of March 1, 2022 as files in the older formats are compatible with the new ones. To support data consumers who are unable to update their data processing by March 1, 2022, GLEIF provides ‘Extensible Stylesheet Language Transformations’ (XSLT) which allow these data consumers to transform the newer versions, from a technical format perspective, into the previous versions.

GLEIF has made many supporting resources available on its website, including technical details, example files and a guiding document for the transition period from March 1 to 31, 2022.

After March 31, 2022, GLEIF anticipates a period of up to one year before the Global LEI System will be fully populated with information on Legal Entity Events, Fund Relationships and Government Entities. Data is generally collected at the time of new LEI issuance or existing LEI renewal.

Continuous Access to GLEIF Data in RDF on data.world

In advance of the impending deadline, GLEIF can confirm that a successful collaboration with data.world has ensured that all GLEIF data in RDF (Resource Description Framework) hosted by data.world – which includes the entire Golden Copy XML dataset – has been updated to the new file formats. This will ensure seamless access to LEI linked open data for the global LEI community by data.world, the world’s largest open data community. data.world hosts an Saas-based enterprise data catalog comprising nearly 500,000 open datasets.
