SOFTWARE INTERFACE FOR MAINTENANCE INFORMATION COLLECTION
AND ANALYSIS (SIMICA) –
Part 2: Exchanging Maintenance Action Information via the Extensible
Markup Language (XML)
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC document(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members
of IEEE and serve without compensation. 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 contained in its standards. Use of IEEE Standards documents is wholly
voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see
https://standards.ieee.org/ipr/disclaimers.html for more information).
IEC collaborates closely with IEEE in accordance with conditions determined by agreement between the two
organizations. This Dual Logo International Standard was jointly developed by the IEC and IEEE under the terms
of that agreement.
2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus of
opinion on the relevant subjects since each technical committee has representation from all interested IEC
National Committees. The formal decisions of IEEE on technical matters, once consensus within IEEE Societies
and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially
interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards
document is given by the IEEE Standards Association (IEEE SA) Standards Board.
3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National
Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical
content of IEC/IEEE Publications is accurate, IEC or IEEE cannot be held responsible for the way in which they
are used or for any misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
(including IEC/IEEE Publications) transparently to the maximum extent possible in their national and regional
publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional
publication shall be clearly indicated in the latter.
5) IEC and IEEE do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are not responsible
for any services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or IEEE or their directors, employees, servants or agents including individual
experts and members of technical committees and IEC National Committees, or volunteers of IEEE Societies and
the Standards Coordinating Committees of the IEEE Standards Association (IEEE SA) Standards Board, for any
personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for
costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC/IEEE
Publication or any other IEC or IEEE Publications.
8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that implementation of this IEC/IEEE Publication may require use of material
covered by patent rights. By publication of this standard, no position is taken with respect to the existence or
validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying
Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or
scope of Patent Claims or determining whether any licensing terms or conditions provided in connection with
submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory.
Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk
of infringement of such rights, is entirely their own responsibility.

Abstract: Promoting and facilitating interoperability components of automatic test systems where
actions taken during maintenance need to be shared is addressed in this standard. The standard
thus facilitates the capture of maintenance action information data in storage devices and databases,
facilitating online and offline analysis. The maintenance action information schema becomes a
class of information that can be used within the SIMICA family of standards. The exchange format
is expressed in both the OWL and XML formats.

Important Notices and Disclaimers Concerning IEEE Standards Documents
IEEE documents are made available for use subject to important notices and legal disclaimers. These notices
and disclaimers, or a reference to this page, appear in all standards and may be found under the heading
“Important Notices and Disclaimers Concerning IEEE Standards Documents.” They can also be obtained on
request from IEEE or viewed at http://standards .ieee.or g/ ipr/ disclaimers.html .
Notice and Disclaimer of Liability Concerning the Use of IEEE Standards
Documents
IEEE Standards documents (standards, recommended practices, and guides), both full-use and trial-use,
are developed within IEEE Societies and the Standards Coordinating Committees of the IEEE Standards
Association (“IEEE-SA”) Standards Board. IEEE (“the Institute”) develops its standards through a consensus
development process, approved by the American National Standards Institute (“ANSI”), which brings
together volunteers representing varied viewpoints and interests to achieve the final product. IEEE Standards
are documents developed through scientific, academic, and industry-based technical working groups.
Volunteers in IEEE working groups are not necessarily members of the Institute 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 Standards do not guarantee or ensure safety, security, health, or environmental protection, or ensure
against interference with or from other devices or networks. Implementers and users of IEEE Standards
documents are responsible for determining and complying with all appropriate safety, security, environmental,
health, and interference protection practices and all applicable laws and regulations.
IEEE does not warrant or represent the accuracy or content of the material contained in its standards, and
expressly disclaims all warranties (express, implied and statutory) not included in this or any other document
relating to the standard, including, but not limited to, the warranties of: merchantability; fitness for a particular
purpose; non-infringement; and quality, accuracy, effectiveness, currency, or completeness of material. In
addition, IEEE disclaims any and all conditions relating to: results; and workmanlike effort. 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.
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 his or
her 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:
PROCUREMENT OF 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 development 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 should be considered 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, or 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 his or her
views should be considered the personal views of that individual rather than the formal position of IEEE.
Comments on standards
Comments for revision of IEEE Standards documents are welcome from any interested party, regardless
of membership affiliation with IEEE. However, IEEE does not provide 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 Standards
Coordinating Committees 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 revisions to an IEEE standard is welcome
to join the relevant IEEE working group.
Comments on standards should be submitted to the following address:
Secretary, IEEE-SA Standards Board

Piscataway, NJ 08854 USA
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 imply 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.
Copyrights
IEEE draft and approved standards are copyrighted by IEEE under U.S. and international copyright laws. They
are made available by IEEE and are adopted for a wide variety of both public and private uses. These include
both use, by reference, in laws and regulations, and use in private self-regulation, standardization, and the
promotion of engineering practices and methods. By making these documents available for use and adoption
by public authorities and private users, IEEE does not waive any rights in copyright to the documents.

Photocopies
Subject to payment of the appropriate fee, IEEE will grant users a limited, non-exclusive license to photocopy
portions of any individual standard for company or organizational internal use or individual, non-commercial
use only. To arrange for payment of licensing fees, please contact Copyright Clearance Center, Customer
Service, 222 Rosewood Drive, Danvers, MA 01923 USA; +1 978 750 8400. Permission to photocopy portions
of any individual standard for educational classroom use can also be obtained through the Copyright Clearance
Center.
Updating of IEEE Standards documents
Users of IEEE Standards documents should be aware that these documents may be superseded at any time
by the issuance of new editions or may be amended from time to time through the issuance of amendments,
corrigenda, or errata. A current IEEE document at any point in time consists of the current edition of the
document together with any amendments, corrigenda, or errata then in effect.
Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years
old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of
some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that
they have the latest edition of any IEEE standard.
In order to determine whether a given document is the current edition and whether it has been amended
through the issuance of amendments, corrigenda, or errata, visit IEEE Xplore at http://ieeexplore .ieee .or g/ or
contact IEEE at the address listed previously. For more information about the IEEE-SA or IEEE’s standards
development process, visit the IEEE-SA Website at http://standards .ieee.or g.
Errata
Errata, if any, for all IEEE standards can be accessed on the IEEE-SA Website at the following URL: http://
standards .ieee.or g/ findstds/ errata/index .html. Users are encouraged to check this URL for errata periodically.
Patents
Attention is called to the possibility that implementation of this standard may require use of subject matter
covered by patent rights. By publication of this standard, no position is taken by the IEEE with respect to the
existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has
filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-
SA Website at http://standards .ieee.or g/ about/sasb/ patcom/patents .html. Letters of Assurance may indicate
whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation
or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair
discrimination to applicants desiring to obtain such licenses.
Essential Patent Claims may exist for which a Letter of Assurance has not been received. The IEEE is not
responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries
into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions
provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are
reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the
validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility.
Further information may be obtained from the IEEE Standards Association.

Introduction
This introduction is not part of IEEE Std 1636.2-2018, IEEE Standard for Software Interface for Maintenance
Information Collection and Alalysis (SIMICA): Exchanging Maintenance Action Information via the Extensible
Markup Language (XML).
Maintainers of complex systems require the ability to capture and share maintenance action information in a
way that supports such activities as performance analysis, post production product improvement, maintenance
process improvement, and diagnostic maturation. Principal stakeholders of this project include but are not
limited to maintenance organizations within various Departments/Ministries of Defense, the commercial
airlines, the automotive industry, and the telecommunications industry. This standard is being developed as a
component of the IEEE Std 1636™ Software Interface for Maintenance Information Collection and Analysis
(SIMICA) project. SIMICA's purpose is to specify a software interface for access, exchange, and analysis of
product diagnostic and maintenance information. Maintenance action information provides a subset of the
data needed to satisfy SIMICIA requirements.
This document provides the description of the maintenance action information elements.

IEEE Standard for Software Interface
for Maintenance Information Collection
and Analysis (SIMICA): Exchanging
Maintenance Action Information via the
Extensible Markup Language (XML)
1. Overview
1.1 General
Software Interface for Maintenance Information Collection and Analysis (SIMICA) is a family of
IEEE standards, associated web ontologies (OWL), and extensible markup language (XML) schemas which
allow automatic test system (ATS), test result and session information, and maintenance action information to
be exchanged in a common format adhering to the OWL and XML standards.
The SIMICA family of standards has been developed and is being maintained under the guidance of
IEEE Standards Coordinating Committee 20 (SCC20) to serve as a comprehensive environment for integrating
test results, test session information, and maintenance action information, while allowing this unit under test
(UUT) related data to be interchanged between heterogeneous systems.
The SIMICA family of standards is organized as a base Standard (IEEE Std 1636™) and two (2) ‘dot’
standards:
— Test Results and Session Information (IEEE Std 1636.1™)
— Maintenance Action Information (IEEE Std 1636.2™)
The SIMICA base document and its relationship to this document is depicted in Figure 1.
