{"prefix":"xfid","name":"xfid","description":"XframeworkID (XFID) is an open registry of permanent, content-based identifiers for extra-financial disclosure documents associated with labelled bond issuances — green, social and sustainability bond frameworks, Second Party Opinions (SPOs), EU Green Bond Standard pre/post-issuance reviews and\nfactsheets, impact and allocation reports, certifications, assurance reports, and academic research analysing labelled bonds. XFIDs are derived from a SHA-256 hash of the document's canonical content, so an identifier permanently and verifiably denotes one specific document version regardless of where\n the file is hosted — addressing the measured erosion of this disclosure class (23% of tracked documents are no longer accessible at their original URLs). The registry cross-references documents to issuers, bond ISINs, assessment providers and analysts, and is used for citation in academic research, investor due diligence and regulatory monitoring.","pattern":"^XF[A-Z0-9]{8}$","uri_format":"https://xframework.id/$1","providers":[],"homepage":"https://xframework.id","example":"XFI5ICTDJ4","example_extras":[],"deprecated":false,"mappings":{"miriam":"xfid"},"synonyms":[],"keywords":[],"publications":[],"appears_in":[],"depends_on":[],"namespace_in_lui":false,"preferred_prefix":"xfid"}
