Foundation (Understanding of XBRL)

This is a summary of information and resources for someone just getting started with XBRL or who wants to refactor their understanding of XBRL.  Be sure to have read about the need for digital proficiency and about Informatics of Accountancy before you think about XBRL.

Recognize that XBRL is just an extra fancy approach to representing a knowledge graph. Once you have that knowledge represented, you have to be able to process that knowledge in the knowledge graph if you want to do anything useful. Moving properly articulated logic from one technical format to some other technical format is trivial.

Foundation:

As a starting point, have a look at the information in this zip archive, Foundation.zip.

Empty XBRL: (99.61-TestCase-empty-xbrl.xml)

A first thing to understand is the core "stuff" in an XBRL file.  That can be best understood by looking at an "empty" report model and report. Here are all those files for an empty XBRL report model and report. One key point here is that a totally empty XBRL-based report (no facts, no report elements defined, no labels, no references, no relations, no XBRL formulas) is perfectly legal XBRL.  Start your mental trip there.  This step helps you understand the puzzle pieces.

Hello World: (81-TestCase-helloworld.xml)

Here is a Hello World example of an XBRL-based report. It has all the basic moving parts of XBRL and it helps you get your hands dirty with a small report model and small report. This report has one structure.

SFAC 6: (71-TestCase-sfac6-BS1-IS1.xml)

Here is the SFAC 6 example of an XBRL-based report which has three structures.

Other High Quality Examples (index.xml)

This is an ultra high quality set of example XBRL-based report models and reports.  This is effectively a conformance suite of XBRL-based reports that are correct, demonstrating all the different capabilities of the XBRL technical syntax.  The Showcase of Reports is another excellent source of examples.

Repository of Reports (Dashboard.html)

This is a prototype repository of XBRL-based reports.  You can read a list of reports and extract information from those reports.  This repository is small, but it gets several important points across when it comes to making use of XBRL-based information.

Very Basic XBRL Technical Primer:

This is a Very Basic XBRL Technical Primer that gets you going with the XBRL technical syntax should you be interested in those details.

Essentials of XBRL-based Digital Financial Reporting:

This is the best version of Essentials of XBRL-based Digital Financial Reporting (Platinum) This is the first step on your journey to mastery of XBRL-based reporting.

Understanding the Seattle Method:

This is the best information for understanding the Seattle Method. Here is the full set of resources. The PROOF is the best approach to understanding the technical details.  If you want the SUPER PROOF, please contact me.

Mastering XBRL-based Digital Financial Reporting:

This set of documents, Mastering XBRL-based Digital Financial Reporting, is the best collection of information and resources regarding XBRL-based digital financial reporting that I have, organized and synthesized into one set of documents and links.

Multiple Technology Stacks:

Multiple technology stacks are a fact of life.  XBRL is an information exchange format (syntax); one of many.  Each technical format has a set of PROS and a set of CONS.  No technical format is perfect. Being able to move bidirectionally between technical formats is useful.

Relational Knowledge Graph System (RKGS)

Image
Relational Knowledge Graph System (RKGS) is an interesting idea that combines the relational paradigm and the knowledge graph paradigm.  This documentation, Why RKGS , explains the idea. This gets even more interesting with the notion of "relational AI".  RelationalAI is described as follows by the company of the same name, Relational.ai : “RelationalAI is a cloud-based relational knowledge graph management system, with state of the art probabilistic processing and declarative reasoning at scale to make developing Data Applications a superpower for your business.” This notion of knowledge graphs represented in relational databases fits into my belief that knowledge graphs have two aspects: the expression SYNTAX and the logic of what is expressed or SEMANTICS. While the LOGIC of a knowledge graph is always the same regardless of technical syntax used to express that logic; there are many, many different technical syntaxes that can be used to represent a knowledge graph. There

Getting Started with Auditchain Luca

Image
(Note that a newer, production version as opposed to only the development version , of Luca Suite is available) The Innovator's Dilemma points out that disruptive innovations often look like toys that are doing everything wrong. Auditchain Luca , which is part of the Auditchain Suite , is a unique approach to creating a knowledge graph .  To experience using Auditchain Luca, have a look at the Getting Started with Auditchain Luca instructions. Be sure to grab the Excel and JSON import files used for this getting started exercise.   This getting started exercise uses one of several different approaches to getting information into a tool for constructing and viewing professional quality knowledge graphs .  Additional getting started guides will be made available over time. Auditchain Luca might not make sense to you if you don't understand the paradigm shift that is occurring and if you have not shifted your mental map. For the next step in your journey, consider trying creat

Evaluating the Quality of XBRL-based Financial Reports

Image
From the time public companies started submitting XBRL-based financial reports to the U.S. Securities and Exchange Commission, I have been looking at those reports, trying to understand the XBRL-based reports, and trying to figure out how to get them right.  That information was used to figure out how to create software applications that help professional accountants get these reports right. Here is information that summarizes my testing and results which I stopped doing March 31, 2019: Analysis of the high level accounting relationships in the 10-Ks of about 5,716 financial reports  (5,063 public companies, about 89.1% got all these high level accounting relationships consistent with expectation, 623 were inconsistent and manual confirmation revealed the inconsistency was an error) Documentation that helps you understand 26 different types of errors in XBRL-based reports High quality documentation of hundreds of errors in XBRL-based reports submitted by public companies to the SEC Doc
