Structured CSV: Expressing XML Hierarchies in a Single Sheet
Views: 2 Structured CSV: Expressing XML Hierarchies in a Single Sheet Nobuyuki Sambuichi 2025-04-13 Structured CSV is a standards-based format derived from the xBRL-CSV specification, enabling complex hierarchical data to be recorded in a flat, tabular form. It is not a simple dump of relational tables. Instead, it uses structured conventions and a metadata-driven approach to express multi-level business documents — such as invoices or journal entries — in a single CSV sheet. 1. Based on xBRL-CSV Structured CSV follows the xBRL-CSV syntax model, where: A CSV file holds the fact data — one row per fact. A JSON metadata file defines the table structure, the dimensions and members for […]

W3C CSV Schema and xBRL-CSV with Hierarchical Tidy Data Typed Dimension Taxonomy
Views: 5 I. Outline of Standards: W3C CSV Schema and xBRL-CSV with Hierarchical Tidy Data Typed Dimension Taxonomy Both W3C CSV Schema and Hierarchical Tidy Data with Typed Dimension Taxonomy in xBRL-CSV are structured ways of working with CSV files for data exchange, validation, and reporting. However, they have different purposes, capabilities, and use cases. Here’s a detailed comparison between the two: 1. W3C CSV Schema The W3C CSV Schema is part of the “CSV on the Web” family of standards developed by the World Wide Web Consortium (W3C). It defines a structured way to describe, validate, and manage CSV data using schemas. The schema provides a way to attach […]

Handling Hierarchical Tidy Data in Financial Reporting
Views: 8 Handling Hierarchical Tidy Data in Financial Reporting Nobuyuki SAMBUICHI In this blog post, we will explore how to handle hierarchical tidy data in financial reporting. We will discuss how to merge necessary data into target rows to summarize amounts based on debit/credit codes, account numbers, and months, ensuring efficient data management and avoiding redundancy. 1. Characteristics of a hierarchical tidy data Hierarchical tidy data reports different levels of observation in different rows, resulting in no redundant report files. However, we need to merge necessary data into a target row to summarize amounts based on debit/credit codes, account numbers, and months. The entered date is reported in a header […]

Hierarchical Tidy Data
Views: 9 Hierarchical Tidy Data 1. Wickham’s Definition Hadley Wickham defines tidy data as follows: 1. Each variable forms a column: Each variable in a dataset is placed in its own column. 2. Each observation forms a row: Each observation is placed in its own row. 3. Each type of observational unit forms a table: Each cell contains a single value. This definition of tidy data facilitates data analysis and visualization and allows consistent data handling. It is important to note that tidy data imposes restrictions on the types of observations by specifying “each type of observational unit”. If we remove this restriction and just specify “observational units”,this means that […]

Requirements for XBRL-GL SRCD Taxonomy Using XBRL-CSV with Hierarchical Tidy Data Structure
Views: 2 Requirements for XBRL-GL SRCD Taxonomy Using XBRL-CSV with Hierarchical Tidy Data Structure 1. Prerequisite Understanding XBRL-GL SRCD Taxonomy with XBRL-CSV 1.1. Difference Between FR and GL XBRL Financial Reporting (FR) and Global Ledger (GL) serve distinct purposes: XBRL FR: Used for high-level financial reporting like balance sheets and income statements for external stakeholders. Elements in XBRL FR summarize financial data. XBRL GL: Captures detailed, transaction-level information for internal use, such as audit trails and operational reporting. It requires a finer granularity of ata, with elements capturing every minute detail of financial transactions. 1.2. Role of SRCD in XBRL-GL The SRCD module connects detailed GL data with FR summaries: […]
