Akoma Ntoso is an international and standard that is widely used by libraries, museums,
publishers, and individual scholars to represent all kinds of textual
material for online research and teaching [AKN].
This document defines the 'application/akn+xml' media type in
accordance with [RFC3023] in order to enable generic processing of
such documents on the Internet using eXtensible Markup Language (XML)
2. Recognizing Akoma Ntoso Files
Akoma Ntoso files are XML documents or fragments having the root element (as
defined in [W3C.REC-xml-20081126]) in an Akoma Ntoso namespace. Akoma Ntoso namespace
names are defined as a Universal Resource Identifier (URI) [RFC3986]
in accordance with [W3C.REC-xml-names-20091208] and begins with
XXX or XXX followed by the version number of the
namespace. The current namespace is XXX
The root element name for Akoma Ntoso documents is
A document having root element
Akoma Ntoso files are often given the extensions .akn.
3. Fragment Identifier
Documents having the media type 'application/akn+xml' use the
fragment identifier notation as specified in [RFC3023] for the media
4. Security Considerations
An XML resource does not in itself compromise data security. When
being available on a network simply through the dereferencing of an
Internationalized Resource Identifier (IRI) [RFC3987] or a URI, care
must be taken to properly interpret the data to prevent unintended
access. Hence the security issues of [RFC3986], Section 7, apply.
In addition, as this media type uses the "+xml" convention, it shares
the same security considerations as described in RFC 3023 [RFC3023],
Section 10. In general, security issues related to the use of XML in
IETF protocols are treated in RFC 3470 [RFC3470], Section 7. We will
not try to duplicate this material, but review some aspects that are
important for document-centric XML as applied to text encoding.
4.1. Harmful Content
Any application accepting submitted or retrieving Akoma Ntoso XML for
processing has to be aware of risks connected with injection of
harmful scripts and executable XML. XML inclusion
[W3C.REC-xinclude-20061115] and the use of external entities are
vulnerable to various forms of spoofing, and can also reveal aspects
of a service in a way that may compromise its security. Any
vulnerability of these kinds are, however, application specific. The
Akoma Ntoso namespaces do not contain such elements.
4.2. Intellectual Property Rights
Akoma Ntoso documents often arise in digitization of legal documents
and legislative documents. Texts made accessible in Akoma Ntoso format
may be unrestricted
in the sense that their distribution may be unlimited by Digital
Rights Management [DRM] or Intellectual Property Rights [IPR]
constraints. However, Akoma Ntoso documents are heterogeneous. Some parts
of a document may be unrestricted, whereas others, such as editorial
text and annotations, may be subject to DRM restrictions.
The Akoma Ntoso format provides means for highly granular attribution, down
to the content of individual XML elements. Software agents
participating in the exchange or processing Akoma Ntoso may be required to
honour markup of this kind. Even when there are no IPR constraints,
intellectual property attribution alone requires that document users
be able to tell the difference between content from different
4.3. Authenticity and confidentiality
Legal and legislative documents may be binding centuries after they were written.
Digitization and encoding of such texts may require technologies for
assuring authenticity, such as cryptographic checksums and electronic
Similarly, such documents may in part or in their entirety be
confidential. This may be required by law or by the terms and
conditions, such as in the case of donated or deposited text from
private sources. A text archive may need content filtering or
cryptographic technologies to meet such requirements.
5. IANA Considerations
5.1. Registration of MIME Type 'application/akn+xml'
MIME media type name: application
MIME subtype name: akn+xml
Required parameters: None
Optional parameters: charset
the parameter has identical semantics to the charset parameter
of the "application/xml" media type as specified in RFC 3023
Identical to those for 'application/xml'. See RFC 3023
[RFC3023], Section 3.2.
See Security Considerations (Section 4) in this specification.
Akoma Ntoso documents are often given the extension '.xml', which is
not uncommon for other XML document formats.
This media type registration is for Akoma Ntoso documents [AKN] as
described here. Akoma Ntoso syntax is defined in a schema [AKNschema].
Applications which use this media type:
There are currently no known applications using the media type
There is no single initial octet sequence that is always
present in Akoma Ntoso documents.
Common extension is '.akn'. See Recognizing Akoma Ntoso
files (Section 2) in this specification.
