Introduction
This EDGAR XBRL Guide provides detailed technical specifications of XBRL formatting and validation
for use in connection with making submissions on EDGAR.
For all submissions, filers should refer to and must comply with the requirements in the EDGAR Filer
Manual (“EFM”).
Chapter 6, Volume II of the EFM, Interactive Data, contains requirements for Interactive Data
submissions in EDGAR using XBRL. That chapter also explains the use of taxonomies and instances that
comprise the XBRL model. Chapter 3, Volume II of the EFM, Index to Forms, contains a discussion of
different XBRL formatted documents associated with relevant EDGAR form and submission types.

1 Fundamentals
Interactive Data submissions in EDGAR use the Extensible Business Reporting Language (XBRL)
information model. To understand the preparation and processing of Interactive Data in EDGAR it is
important to be familiar with XBRL’s key ideas and terminology, as well as how XBRL differs from other
formats.
Facts and Concepts. XBRL defines computer-readable facts for business reporting. A fact represents a
single numeric item, or an arbitrarily sized section of text (a non-numeric fact). In EDGAR, a fact that
appears in a submission is an assertion being made by a filer to satisfy an SEC disclosure requirement.
Each fact is characterized by a set of core standard dimensions:
•
•
•
•

the period for which the fact is asserted,
the business entity that it is about,
the human language in which the text is written (US English, in EDGAR),
for numeric facts, the unit of measure and number of decimal places that are not significant.

Each fact is an occurrence of a concept that makes it comparable to other facts. For example, “Public
Float” could be an SEC-defined concept for which a fact “10 billion US dollars, with nine digits (zeroes)
not shown” has the same meaning whether it is a fact about entity ABC as of February 14, 2030, or a fact
about entity XYZ as of January 12, 2025. Concepts have a data type and validations that constrain their
possible values. Continuing the example, facts of the Public Float concept value should not be negative
and must be expressed in US Dollars.
Instances and Formats. A set of XBRL facts is called an XBRL instance. An instance is computerreadable data that may be stored or transmitted written out in its original XML-based file format
10

(“xBRL-XML”) or embedded into HTML documents (“Inline XBRL”). In XBRL formats currently used
in EDGAR, the location of facts within a file has no impact on their meaning. Also, an instance is not
necessarily one EDGAR file attachment; Inline XBRL allows instances to be distributed across, and
embedded into, more than one file attachment within a submission. XBRL defines the facts of an instance
– its information model, not just file formats – and this is a unique defining characteristic of XBRL
specifically intended to support technology changes.
Taxonomies and Dimensions. Another defining characteristic of XBRL is how concepts are defined via
XBRL taxonomies. A taxonomy consists of concepts, along with relationships among concepts and with
other computer-readable data. Relationships can be thought of as arcs in a graph, each with a source (or
parent) concept and target (or child). The type of relationship is called role of the arc, i.e., its arc role.
Some of these relationships describe the various dimensions along which a fact may be characterized. A
fact may have any number of taxonomy-defined dimensions, conventionally called axes, each of which
has a domain of possible values. As a mnemonic for axes and dimensions, it may be helpful to visualize a
physical object such as a book. It has three axes: height, width, and depth. The dimensions of the book
might be seven inches high, five inches wide, and one inch deep. Each of the book’s axes has the same
domain: positive numbers.
Domains may be infinite, like the number of inches, or may have a set of explicit members. For example,
a taxonomy might define a “Country” axis, whose explicit members are countries. In this way, the facts
“ABC Inc’s Bermuda 2025 Revenue is $10m” and “ABC Inc’s Bonaire 2025 revenue is $10m” are
distinct. Their “dimensions” are “country Bermuda” and “country Bonaire”, respectively. For a fact that
does not specify an explicit member of an axis, there may be an unstated default member that represents
all members of that axis collectively. The fact “ABC Inc’s 2025 Revenue is $20m” therefore refers to its
global revenue. A taxonomy specifies for every concept what dimensions are required, permitted, or
forbidden for facts of every concept. EDGAR validates each XBRL instance against the relevant
taxonomies to ensure that every fact has all the required dimensions and none of those dimensions are
forbidden.
Modularity and Documentation. EDGAR taxonomies that support specific SEC rule releases are
accompanied by technical documents called taxonomy guides that detail the concepts and other aspects of
how the taxonomy is used. Since their introduction in 2009, new EDGAR taxonomies have been
introduced and have evolved, resulting in differences in naming conventions, organization of files, and
other matters. All EDGAR taxonomies are currently updated at least annually, for the most part via an
EDGAR release occurring in the first quarter of each calendar year and removed from use after two years.
All taxonomies used in an instance must be from the same calendar year but are otherwise technically
independent and can be mixed and matched to suit the regulatory disclosures present in a submission.
This organization of taxonomies is a different approach than EDGAR’s technical guides for online forms.
Meta data. Taxonomies contain several computer-readable relationships other than the dimensiondefining relationships outlined above. A concept in a taxonomy will be annotated with text labels,
authoritative references, data quality validations, simple arithmetic calculations, and ordering and nesting
relationships among concepts that that detail how software should create a tabular presentation of facts
extracted from an instance. These relationships are ideally independent of which SEC Form, EDGAR
Submission Type, or Exhibit the concepts will be used for.
For example, the concept “Entity Filer Category” has an authoritative reference to the Exchange Act
240.12b-2 which contains definitions of the terms. The Entity Filer Category concept also appears in a
presentation link that provides a conventional order of presentation with respect to related concepts such
as “Entity Voluntary Filers” and “Entity Well Known Seasoned Issuers” that may appear on the cover
page of several different Forms in the same relative positions. In XBRL taxonomies, these relationships
are stored in linkbases and may be embedded in XML Schemas; informally, these additional relationships
and annotations are taxonomy metadata. They are often first created, reviewed, and used in various
11

tabular styles, leaving the details of the technical syntax to software. Many submission types and exhibits
require a filer-constructed custom taxonomy as part of the submission.
Validation. An EDGAR submission with XBRL attachments proceeds through multiple validation steps
prior to acceptance. The validations are defined at several levels:
(a) file format syntax, be that defined by the syntax of XML, XML Schema, XHTML, or XBRL
specifications;
(b) syntax restrictions that are specific to EDGAR – for example, limitation on the XHTML tags that may
appear in Inline XBRL;
(c) semantic consistency of the instance – for example, ABC Inc’s Bonaire 2025 cannot be $10m one
location in an instance and $11m in another;
(d) semantic consistency of the facts and the meta data – for example, if country Barbados is not a
dimension, there can be no fact “ABC Inc’s Barbados Inventory”, and if it is present, Inventory should not
be a negative number; and
(e) submission-, form- and exhibit-specific checks – for example, instance type QF.US should have a
reporting period consistent with the 1st, 2nd or 3rd quarter of the company’s fiscal year.
All levels contribute to data quality although the term is mainly associated with levels (c), (d) and (e).
Generally, the consequences of failed validations are either XBRL Errors, which may cause suspension,
or XBRL Warnings, which do not cause suspension.
XBRL Submissions. Disclosure requirements that detail which entities are required to make what
disclosures at what times and under what circumstances are ultimately to be found in the SEC rules and/or
Form instructions. This document covers the steps for making those disclosures, and it details the
relevant validations. In that way this document supplements the EDGAR Filer Manual and XBRL
specifications, while providing a background for each individual Taxonomy Guide. The high-level steps
for an EDGAR submission with XBRL attachments are listed below:
1. Identify the correct Form type, submission type, and exhibits; this determines the instance type
[§ 6.1].
2. The relevant taxonomy entry points for that instance type [§ 6.3].
3. Identify the permitted formats for the instance attachments [§ 6.4]; choose valid mnemonic file
names.
4. Identify the facts that are expected; their absence could result in EDGAR suspending the submission.
5. Identify the facts required for the disclosure, especially those with EDGAR validation warnings.
6. Determine where there will be concepts reported for more than one event, asset class, business
segment or any disaggregation represented in the taxonomy and required in the disclosure.
7. Determine any non-standard (“custom”) concepts needed and their supporting properties.
8. Create the custom taxonomy (if needed) and files for the instance.
9. Validate the instance, interpret errors and warnings, and correct them.
10. Preview the submission as it will be rendered on the SEC.gov web site.
11. Validate the entire submission and all its attachments, usually as a TEST submission.
12. Resolve the errors and warnings, repeat 11 as needed, then submit as a LIVE submission.

2 XBRL Specifications
XBRL International Inc. (XII) defines and updates the technical specifications, primers, test cases, and
other resources for XBRL syntax, via committees and working groups whose draft publications are open
to the public. EDGAR processes XBRL formatted files in submissions to create instances and validates
that they conform to specifications.
New versions of specifications are published at https://specifications.xbrl.org from time to time. EDGAR
does not use all parts nor the latest of all XII specifications. New specifications are not permitted in
EDGAR submissions until finalized. New specifications are permitted only through the periodic EDGAR
release and the filer manual update processes. The specifications currently governing the technical syntax
of all EDGAR instances are:
•
•
•
•
•
•
•

XBRL version 2.1
XBRL Calculations version 1.1
XBRL Dimensions version 1.1
XBRL Extensible Enumerations version 1.0
XBRL Extensible Enumerations version 2.0
XBRL Open Information Model (OIM) 1.0 Common
xBRL-XML Mapping for OIM 1.0

Additionally, the current XII specification governing the Inline XBRL format of instances is:
•

Inline XBRL version 1.1

XII publishes widely shared enhancements that do not require new specifications via registries. EDGAR
currently permits use of entries in these registries:

XII also creates and publishes taxonomies. Currently none of the XII taxonomies are EDGAR standard
taxonomies.

3 Instance Validations
The content of an instance is illustrated here using Form 6-K.

13

EFM § 3 shows that Form 6-K may be submitted either as submission type 6-K or, if an amendment of a
prior 6-K, submission type 6-K/A. The tables in EFM v68 § 6 (duplicated in this document in section 11
below), show that:
•

Submission types 6-K and 6-K/A are in submission set 6K [§ 6.1.1];

•

Submission set 6K is paired only with entity set FPI and maps to instance type 6K.A [§ 6.1.3];

•

Instance type 6K.A requires entry point dei and may use us-gaap or ifrs and any of the other
entry points on the row labeled ALL [§ 6.3];

•

Instance type 6K.A is not one of the exceptions to the general requirement that the format be
Inline XBRL, so it is an Inline XBRL attachment. [§ 6.4].

The first few lines of the file shown below have a root html element and a namespace prefix ix that
establish it is an Inline XBRL file; see [§ 5.2.5] for more detail. The link:schemaRef attribute
xlink:href means that it uses the dei-sub entry point that contains labels, presentation, and definition
links of the 2024 version of the dei taxonomy:

…

Regarding the Inline XBRL markup, the preparer of a 6K.A instance needs to know the following data
points:
•

The form type, as distinct from the submission type;

•

The company CIK and its EDGAR conformed name;

•

The month and day of the current fiscal year end;

•

For current reports in submission sets 8K and 6K, the date of the earliest event reported;

•

In an amending submission (a submission type in submission set AM), whether the content of any
XBRL facts have changed; and

•

If the content of any XBRL facts changed, how.

Each of these data points is represented in an instance as a fact in the same context.

3.1 Expected Facts in the Required Context
Every instance type has some facts that are expected to be present and have specific values in the
instance. Each such fact has a concept from a standard taxonomy as defined in EFM v68 § 6.2.2. The
context of the fact will have:
1. an entity identifier matching the filing CIK, and
2. either
a. no taxonomy-defined dimensions, or
14

b. a dimension from a standard taxonomy, and
3. either a period whose end date matches the reporting period end, which may be
a. an instant, or
b. a duration matching the quarter or year of the submission reporting period, or
c. a duration of one day representing the intended date of submission.
Conditions 1, 2.a, and either 3b or 3c jointly define the required context. There may be more than one
context that matches all four conditions, in which case 3.c takes precedence over 3.b.
Every instance type has expected facts in a required context. For example, every instance must have a
fact in the required context having concept dei:EntityCentralIndexKey whose value is the 10-digit
CIK matching the CIK described in condition 1. One CIK must be chosen even when there are multiple
co-registrants in the submission.
Other contexts meeting conditions 1.b, 2, and 3 are defined below in relation to certain expected facts.
For example, some expected facts for multi-series filers expect a context with an explicit member of
dei:LegalEntityAxis and otherwise identical to the Required Context.
Expected facts may also be subject to additional conditions:
4. The fact may be required to be either present or absent (attribute xsi:nil = true is normally the
same as being absent).
5. The fact value may be expected to have a value that is consistent with
a. EDGAR’s existing data for a company, or
b. data from the EDGAR submission header, or
c. other facts in the same instance.
6. The fact may be expected outside of element ix:header of an Inline XBRL file [§ 5.2.5.14].
Inline XBRL permits the same concept to appear more than once in the same context, possibly
inside and outside of ix:header; in that case the condition of one occurrence appearing outside
ix:header is sufficient.
Symmetrically, there are also validations for unexpected facts. Facts that are expected for one instance
type may be unexpected (resulting in an XBRL warning or error) or optional (no warning or error is
produced) or for other instance types. These conditions vary by instance type.

3.1.1 Notation and Terminology
This guide describes each fragment of expected content in two tables, a Concepts table and a Validations
table.
The Concepts table shows:
•

The concept with its standard namespace prefix (sometimes, an EDGAR header field);

•

A concept # in the style {1}, {2} etc. to be referenced in the Validations table;

•

An XML or XBRL data type, or a POSIX regular expression (regex) of possible string values;

•

A short indication of the concept meaning, which is often apparent from the concept name, along
with any detail notes such as related Inline XBRL transformations (in some tables the cell is
blank because the concept has been defined in a previous Concepts table).

An example Concepts table is shown below.

Included submission sets (prefixed by “s: ”) and included instance types (prefixed by “i: ”)

•

Excluded submission sets (prefixed by “s: ”) and excluded instance types (prefixed by “i: ”)

•

c - a code indicating the contexts to which it applies (r: required; a: all; etc.) This implies that
even if a fact is expected in a restricted context, it is may or may not appear in other contexts.

•

Check - the condition to be tested

•

f - a footnote indication for special cases, exceptions, or additional detail notes,

•

On failure – the condition raised when the check fails,

•

s - the severity of the violation (E: Error, W: Warning),

•

and (in this version of the guide) a reference to version 68 of the EDGAR Filer Manual (for
example, “§ 6.5.21 X” refers to the code X appearing in the table of section 6.5.21; “§ 6.5.46 []”
refers to a blank cell in the table of section 6.5.46).

The consequences of an XBRL Error may vary depending on the instance type, as discussed in [§ 6.6].
However, an XML syntax error (such as a five-digit number where a ten-digit number is required or an
unknown country code) always results in an XBRL Error. Failed validations of expected facts may be
Errors or Warnings.
XBRL Warnings indicate that facts found in the instance are in some way incomplete, inconsistent with
each other, misleading, ambiguous, or unreliable and this will have undesirable downstream consequences
for users of the data. Filers should avoid XBRL warnings by correcting the data prior to live submission.
Within the validations table, a fact is visible in an Inline XBRL file if it is not located within the
ix:hidden element. If the fact has duplicates, at least one must be located outside of ix:hidden. A fact is
present in a context if it has a non-nil value; a fact is deemed to be absent if it either does not exist or
exists only with a nil value.
Each validations table is followed by notes or special cases from the footnote (f) column.

3.1.2 Required Context validation

Notes and special cases:
1. The conformed name must be a case-insensitive prefix of the fact value. For example, conformed name
"SMITH" would match fact text "Smith, John". These differences are ignored:
a. Differences in whitespace or punctuation; hyphen characters (-, -) may either match whitespace or
nothing. For example, "ABC Real-time" will match both "A.B.C. RealTime" and "ABC, Real
Time".

b. Single-character words are ignored; "A. B. SMITH" will match "SMITH A".
c. Text entered between "//", such as "ABC CO /DE/", matches "ABC CO".
d. Matching abbreviations that EDGAR imposes, such as truncating CORPORATION to CORP,
shortening "and" to ampersand "&", and dropping the word "The" at the beginning. For
example, "The Smith and Jones Corporation" matches "SMITH & JONES CORP".
2. When the required context CIK is 00000000000, the name match is waived.
3. The cover pages of certain forms distinguish the "Exact name of Registrant as specified in its
charter" from the "Translation of Registrant’s name into English". If either differs from the
conformed name, then an additional dei:EntityRegistrantName fact with an xml:lang attribute
value not starting with en is expected.

3.1.24 Closed-end fund registration
The cover page of Form N-2 has over 30 check box, date, amendment, and file number facts, many of
which have interdependent values or are mutually exclusive. The subsections below break these facts into
related groups.
Note that unlike other Checks involving facts in the required context, violation of these is more likely to
raise an error, not a warning.
Most concepts related to these Checks are in the dei namespace; a few are specific to closed-end funds
and thus appear in the cef taxonomy.

3.2 Expected Facts with Dimensions
Taxonomy-defined dimensions, as introduced in section 1 above, are used to define XBRL hypercubes. In
this document as in all SEC standard taxonomies a taxonomy-defined dimension is called an Axis.
Members of an axis may be its default member, a standard member, or a custom member defined by the
filer. In addition to indicators such as names and indentations within tables, concept types used in this
document are additionally color-coded as shown in Figure 1.
