1 Scope
This Technical Specification contains a formal reference information model of the concepts and methods established in IEC 81 346-1 , IEC 81 346-2, IEC 61 1 75, IEC 61 666 and IEC 81 71 4-3, which are its normative basis. The information model is normative with respect to data exchange.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 81 346-1 , IEC 81 346-2, IEC 61 1 75, IEC 61 666, and IEC 81 74-3 apply.
4 General
The standards IEC 81 346-1 , IEC 81 346-2, IEC 61 1 75, IEC 61 666 and IEC 81 71 4-3 are interrelated, but the concepts used in these standards have so far only been dealt with separately in the different publications. The purpose of the present technical specification is to illustrate their relations by means of a common reference information model. When data is transferred or exchanged, the exchange shall conform to this reference model. The model is conceptual and independent from any implementation method. For the preparation of the information model, the EXPRESS modelling language, described in ISO 1 0303-1 1 , has been used. The graphical form is presented using EXPRESS-G. The information model is contained in Annex A. 0 provides an overview by means of a graphical representation of the structure and constraints of the application objects. The computer interpretable textual form is represented in A.3. A.1 lists the entities and attributes of the information model and A.2 contains the detailed verbal descriptions of the entities and attributes. The reference information model depicts the requirements set up, using where possible available subsets of application reference models of the ISO 1 0303 series. The model is not intended to be complete within the framework of neither integrated resource models nor application reference models developed within the ISO 1 0303 series. It is complete with respect to the requirements established within this publication. NOTE 1 For an introduction to EXPRESS-G, see http://tc3.iec.ch/txt/xpress.pdf. NOTE 2 Annex A is available in the English language only. Annex B contains a set of source definitions for Data Element Types (DETs) derived from the common reference information model.NOTE 1 The identification number is listed in the IEC CDD as code under which it is stored in the dictionary. NOTE 2 The attributes preferred name and definition are provided in the English language only, as the English language is the reference language of the IEC CDD. The IEC CDD allows adding national language variants to the dictionary under the control of the relevant National Committee. NOTE 3 The DETs defined in this publication have been forwarded for standardization and inclusion in the IEC CDD following the procedure defined in Annex SL of ISO/IEC Directives, IEC Supplement: 201 2: Procedures specific to IEC. The intent of this procedure is to make the DETs available in the IEC CDD at the time of publication of the present publication. Other DETs referenced in this publication are listed in Clause B.3. For these DETs the identification number with link is provided. These DETs are listed under their preferred name, with synonyms or short names indicated, if used in this publication.
