Digital Financial Reporting Wiki (home page)

Information on this wiki is also available summarized in three documents which are located at the Digital Financial Reporting . Information specific to SEC XBRL Financial Reports can be found on this wiki.

Welcome to the digital financial reporting wiki. This wiki helps organize all things needed for "digital" or "21st century" or "model-based" financial reporting. Also called "interactive data" by the SEC, digital financial reporting is on its way.

In order to model financial information such that a computer application can work with this information; the pieces of a financial report need to be broken down into understandable pieces. The Financial Report Semantics and Dynamics Theory provides such a breakdown. This wiki follows that breakdown and expands on what is provided by this theory. Further, this model is instantiated using XBRL and RDF/OWL for use by software applications.

As such, this wiki is about the metadata needed for digital financial reporting. But this wiki only documents the metadata. The actual utility of this model becomes apparent when computer software makes use of this model and additional metadata which is provided.

The resource Digital Financial Reporting: Using an XBRL-based Model summarizes information on this wiki. You can download the chapters of this resource here:

Narrative Overview of the Digital Financial Reporting Model

The following is a narrative overview of this model.

Financial reporting is defined within a conceptual framework. That conceptual framework defines basic elements, components, and other such pieces. This conceptual framework is defined in the US by the FASB. There are other frameworks such as IFRS (International Financial Reporting Standards) which is defined by the IASB. The FASB and IASB are converging their conceptual frameworks. This model (prototype) uses US GAAP but will evolve to the converged FASB/IASB framework.

Financial reporting rules are organized into US GAAP. US GAAP has reporting rules and common reporting practices. These rules and common practices result in common ways reporting entities create their financial reports. These reporting practices include common approaches to organizing disclosures, key ratios, industries (or activities), types of reporting entities, and other pieces of a financial report.

These pieces of a financial report can be organized into sets of meta data which explain the pieces. There are various ways to express this meta data inculding XBRL, RDF/OWL, and other approaches. This meta data can be read and understood by computer applications.

The XBRL medium is used to create a physical digital financial report. Other formats, such as RDF/OWL, RSS, and other standards can be use to support the process of creating digital financial reports. Organizing these mediums and working with them using a logical model which hides the technical syntax can make the process or creating digital financial reports easier.

Reporting entities can be grouped or categorized into different stock sectors or other classification systems.

[To do, need a narrative which ties everything together.]

XBRL is both a technical syntax for exchaning information and a method of modeling that information.

Digital Financial Report Profile for SEC XBRL Financial Filings

A SEC XBRL-based financial filing is one way XBRL is used. A digital financial report profile which articulates a logical model is used to make things easier to understand and use. Find information about that digital financial reporting profile here: logical model for SEC XBRL financial filings.
