\nThis article introduces a Python-based parser to extract a logical hierarchical model (LHM) structure from the XBRL GL taxonomy. The parser also retrieves multilingual labels and documentation from the label linkbase. The output is a structured CSV file useful for semantic analysis, implementation, and documentation.\n<\/p><\/blockquote>\n<\/div>\n<\/div>\n<\/div>\n
\n1. Motivation<\/h2>\n
\n\nThe XBRL Global Ledger (XBRL GL) Palette taxonomy defines an XML-based standard for representing accounting and audit data. However, its hierarchical structure\u2014especially when modularised\u2014can be difficult to navigate, particularly when multilingual labels are defined using labelArc.<\/p>\n<\/div>\n
\nThis script provides a bridge between raw schema definitions and a friendly CSV format enriched with English and localised labels (e.g., Japanese).<\/p>\n<\/div>\n<\/div>\n<\/div>\n
