Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each memb er body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO

collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

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 ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (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 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).

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

This document was prepared by Technical Committee ISO/TC 59, Buildings and civil engineering works,

Subcommittee SC 13, Organization of information about construction works.

This second edition cancels and replaces the first edition (ISO 12006:2007), which has been technically

revised.

The main changes compared to the previous edition to meet industry needs and implementations are as

follows:
- Model is changed and adapted for multiple implementations of dictionaries.
- UML, and XML introduced in informative annexes.
- API specification included.

- Concepts must have relations to other concepts and are more rigid, specific and object orientated.

A list of all parts in the ISO 12006 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction

This document defines a specification for an extensible taxonomy model, which provides the ability to

add concepts like subjects and properties, describe subject by means of properties, and to define

relationships between concepts The set of properties associated with a subject provide the formal

definition of the subject as well as its typical behaviour. Properties might have predefined values, and

they might be associated with units.

The model makes it possible to describe multiple dictionaries based on the same model. Each concept

belongs to one data dictionary. The concepts in one data dictionary might be related to concepts in

another data dictionary.

Every entity in the model has a universal unique identifier. The model allows to describe the development

and maintenance of data dictionary by providing change request, and it also allows to describe the

experts reviewing change requests. The model described in this document is proposed as a bridge

between classification systems as described in ISO 12006-2 [5], and product modelling as described in

several publications [2], [3], [6], [7].

This document supports the requirements for implementation concept in ISO 23386 [8] and ISO 23387

[9].

To simplify and support implementation of dictionaries based on this framework, the standard has

included UML model [10] and XML schema [11] as informative appendices. An API specificationhas been

added as a normative appendix to standardise and define the minimum functionality to extract and

exchange data between dictionaries based on this document.

Building construction — Organization of information about
construction works — Part 3: Framework for object-oriented
information
1 Scope

This document specifies a language-independent information model which can be used for the

development of dictionaries used to store or provide information about construction works. The model

is extended by instantiating content, such as further objects and their relationships, allowing the content

to serve as an ontology, taxonomy, meronomy, lexicon and thesaurus.

It enables classification systems, information models, object models, data templates and process models

to be cross referenced from within a common framework.

This document provides the description of an API allowing the interconnection of data dictionaries as

described in ISO 23386.
