Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide standardization.
National bodies that are members of ISO or IEC participate in the development of
International Standards through technical committees established by the respective
organization to deal with particular fields of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further
maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different
approval criteria needed for the different types of document should be noted.
(see www.iso.org/directives or www.iec.ch/members_experts/refdocs).
IEEE Standards documents are developed within IEEE Societies and subcommittees of IEEE
Standards Association (IEEE SA) Board of Governors. IEEE develops its standards through
an accredited consensus development process, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. IEEE standards
are documents developed by volunteers with scientific, academic, and industry-based
expertise in technical working groups. Volunteers are not necessarily members of IEEE or
IEEE SA and participate without compensation from IEEE. While IEEE administers the
process and establishes rules to promote fairness in the consensus development process,
IEEE does not independently evaluate, test, or verify the accuracy of any of the information
or the soundness of any judgments contained in its standards.
ISO and IEC draw attention to the possibility that the implementation of this document may
involve the use of (a) patent(s). ISO and IEC take no position concerning the evidence,
validity or applicability of any claimed patent rights in respect thereof. As of the date of
publication of this document, ISO and IEC had not received notice of (a) patent(s) which
may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not
be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users
and does not constitute an endorsement.

ISO/IEC/IEEE 39274-1-1 was prepared by the LAN/MAN of the IEEE Computer Society (as
IEEE Std 9274.1.1™-2023) and drafted in accordance with its editorial rules. It was adopted,
under the “fast-track procedure” defined in the Partner Standards Development
Organization cooperation agreement between ISO and IEEE, by Joint Technical Committee
ISO/IEC JTC 1, Information technology, Subcommittee SC 36, Information technology for
learning, education and training.

Abstract: This standard is a collaborative effort to improve and standardize the 1.0.3 version
Experience Application Programming Interface (xAPI) specification. This Standard describes a
JavaScript Object Notation (JSON) data model format and a Representational State Transfer
(RESTful) Web Service Application Programming Interface (API) for communication between
Activities experienced by an individual, group, or other entity and a Learning Record Store (LRS).
The LRS is a system that exposes the RESTful Web Service API for the purpose of tracking and
accessing experiential data, especially in learning and human performance.

Important Notices and Disclaimers Concerning IEEE Standards Documents
IEEE Standards documents are made available for use subject to important notices and legal disclaimers.
These notices and disclaimers, or a reference to this page (https://standards.ieee.org/ipr/disclaimers.html),
appear in all standards and may be found under the heading “Important Notices and Disclaimers
Concerning IEEE Standards Documents.”
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents
IEEE Standards documents are developed within IEEE Societies and subcommittees of IEEE Standards
Association (IEEE SA) Board of Governors. IEEE develops its standards through an accredited consensus
development process, which brings together volunteers representing varied viewpoints and interests to
achieve the final product. IEEE standards are documents developed by volunteers with scientific, academic,
and industry-based expertise in technical working groups. Volunteers are not necessarily members of IEEE
or IEEE SA and participate without compensation from IEEE. While IEEE administers the process and
establishes rules to promote fairness in the consensus development process, IEEE does not independently
evaluate, test, or verify the accuracy of any of the information or the soundness of any judgments contained
in its standards.
IEEE makes no warranties or representations concerning its standards, and expressly disclaims all
warranties, express or implied, concerning this standard, including but not limited to the warranties of
merchantability, fitness for a particular purpose and non-infringement IEEE Standards documents do not
guarantee safety, security, health, or environmental protection, or guarantee against interference with or
from other devices or networks. In addition, IEEE does not warrant or represent that the use of the material
contained in its standards is free from patent infringement. IEEE Standards documents are supplied “AS
IS” and “WITH ALL FAULTS.”
Use of an IEEE standard is wholly voluntary. The existence of an IEEE standard does not imply that there
are no other ways to produce, test, measure, purchase, market, or provide other goods and services related
to the scope of the IEEE standard. Furthermore, the viewpoint expressed at the time a standard is approved
and issued is subject to change brought about through developments in the state of the art and comments
received from users of the standard.

vi
In publishing and making its standards available, IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity, nor is IEEE undertaking to perform any duty owed by
any other person or entity to another. Any person utilizing any IEEE Standards document, should rely upon
their own independent judgment in the exercise of reasonable care in any given circumstances or, as
appropriate, seek the advice of a competent professional in determining the appropriateness of a given
IEEE standard.
IN NO EVENT SHALL IEEE BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL,
EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO: THE
NEED TO PROCURE SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS;
OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY,
WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR
OTHERWISE) ARISING IN ANY WAY OUT OF THE PUBLICATION, USE OF, OR RELIANCE
UPON ANY STANDARD, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE AND
REGARDLESS OF WHETHER SUCH DAMAGE WAS FORESEEABLE.
Translations
The IEEE consensus balloting process involves the review of documents in English only. In the event that
an IEEE standard is translated, only the English version published by IEEE is the approved IEEE standard.
Official statements
A statement, written or oral, that is not processed in accordance with the IEEE SA Standards Board
Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its
committees and shall not be considered to be, nor be relied upon as, a formal position of IEEE. At lectures,
symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall
make it clear that the presenter’s views should be considered the personal views of that individual rather
than the formal position of IEEE, IEEE SA, the Standards Committee, or the Working Group. Statements
made by volunteers may not represent the formal position of their employer(s) or affiliation(s).
Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of
membership affiliation with IEEE or IEEE SA. However, IEEE does not provide interpretations,
consulting information, or advice pertaining to IEEE Standards documents.
Suggestions for changes in documents should be in the form of a proposed change of text, together with
appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is
important that any responses to comments and questions also receive the concurrence of a balance of
interests. For this reason, IEEE and the members of its Societies and subcommittees of the IEEE SA Board
of Governors are not able to provide an instant response to comments, or questions except in those cases
where the matter has previously been addressed. For the same reason, IEEE does not respond to
interpretation requests. Any person who would like to participate in evaluating comments or in revisions to
an IEEE standard is welcome to join the relevant IEEE working group. You can indicate interest in a
working group using the Interests tab in the Manage Profile & Interests area of the IEEE SA myProject
system. An IEEE Account is needed to access the application.
Comments on standards should be submitted using the Contact Us form.

Laws and regulations
Users of IEEE Standards documents should consult all applicable laws and regulations. Compliance with
the provisions of any IEEE Standards document does not constitute compliance to any applicable
regulatory requirements. Implementers of the standard are responsible for observing or referring to the
applicable regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action
that is not in compliance with applicable laws, and these documents may not be construed as doing so.
Data privacy
Users of IEEE Standards documents should evaluate the standards for considerations of data privacy and
data ownership in the context of assessing and using the standards in compliance with applicable laws and
regulations.
