Information technology — Distributed application platforms and services (DAPS) — Framework for distributed real-time access systems
This document specifies a framework for a distributed real-time Access system. It includes: 1) an ID triggered modular system architecture, the functions of the modules, the semantics of messages those modules exchange, and elements of messages; 2) the system behaviour from the time it receives an access request until the time it sends the result along with the sequence; 3) performance measurement mechanisms using a time stamping function that can be employed for the evaluation of the system.

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).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www .iso .org/patents) or the IEC
list of patent declarations received (see http: //patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by Ecma International (as ECMA-412) and drafted in accordance with its
editorial rules. It was assigned to Joint Technical Committee ISO/IEC JTC 1, Information technology, and
adopted under the “fast-track procedure”.
This second edition cancels and replaces the first edition (ISO/IEC 20933:2016), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— added new functionalities on performance management mechanisms;
— editorial improvements and clarifications to the text of the document.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Technology for real-time access control is widely used in many situations such as entrance gates of
facilities and service access control systems. Membership and settlement services also benefit from
real-time access control systems connected via networks and using database information.
Sophisticated cloud, virtualisation, database, networking technology and services and the evolution of
authentication technology such as biometrics, NFC, QR codes used in distributed and modular access
control systems enable previously underserved users and operators to innovate around new use cases.
Taking into account the many technologies, this document specifies the reference model and common
control functions. It gives direction for ongoing innovation and development of technology and system
integration of distributed real-time access control system.
nd
This 2 edition of the Standard introduces new functionalities on performance management
mechanisms. Performance management mechanisms allow an Access system to be evaluated for
performance by using specific elements and metrics. This edition also provides a number of editorial
improvements and clarifications to the text of the Standard.
