Licensing & Citation Policy
XFID identifiers are free to cite. The registry provides additional value through structured metadata, version history, and document access — available through subscription tiers.
Citation Policy
XFID identifiers may be used by Issuers and their agents, brokers, and those supporting an issuance or production of an extra-financial document. This includes referencing XFIDs in term sheets, final terms, prospectuses, and internal systems related to an issuance.
Use of XFIDs in products that are sold for a fee — such as data products, datasets, or commercial platforms — requires a licence. Where XFIDs are used, proper citation is required.
How to Reference an XFID
XFID identifiers are designed to be used wherever sustainable finance documents are referenced. Here are practical examples for common workflows:
In Final Terms or Term Sheets
In Data Feeds or Systems
framework_xfid: XFA3B7K2M9spo_xfid: XFK7P2N4R3 In Research or Reports
The registry URL xframework.id/[XFID] will always resolve
to the document's record page with metadata, related documents, and citation
information.
Data Redistribution
Identifiers: XFID identifiers may be used by Issuers and their agents, brokers, and those supporting with an issuance or production of an extra-financial document or information. They require a licence if used in products that are sold for a fee, in such uses as data products and datasets. Where used, proper citation is required.
XFID is not meant to be a data source, and metadata or information about a document, framework, or other extra-financial information should be sourced from the originator of the information. XFID will confirm which version of the document you are viewing, if it has been changed, and can provide you the original text if that original was since moved or deleted.
Algorithm Transparency
The XFID computation algorithm requires a licence, but any party can independently verify an XFID through the use of the check digit. This is explained on the About page.
This means XFID identifiers are independently verifiable — you do not need to trust the registry to confirm that a given XFID correctly identifies a given document.
