(Main)Framework and Implementation of Common Data Environment solutions and workflow, in accordance with EN ISO 19650
Framework and Implementation of Common Data Environment solutions and workflow, in accordance with EN ISO 19650
This New Work Item will extend the basic information given in the EN ISO19650 and in the "Guidance to EN ISO 19650". It will detail and structure the concept of a Common Data Environment (CDE) as a workflow for the collaborative process of managing the information and information containers as solutions that fit to the management and project processes inherent for BIM
It may be necessary to introduce further concept details as elements for understanding and implementation. Archiving and versioning of information containers can become very complex when considering various typical information situations of a project.
Further elements, rules and terminology for information management and digitisation may need to be explained and technically framed in the context of a CDE. It will be a large advantage developing at the same time the "Open API for CDE" in TC442 WG2
In particular this Work Item will describe
- how to link a CDE according to EN ISO 19650 to an already existing Asset Management Systems of the Asset Owner.
- how to maintain and manage "living documents" like Information Models (AIM, PIM)
- how to maintain, exchange and manage Information Requirements like (OIR, AIR, EIR) as well as BIM Execution Plans (BEP)
- how to use and implement Information Delivery Plans for the above entities (MIDP and TIDP in ISO 19650)
- how to manage and collaborate between various Information Containers like models, requirements, container states
- how to support Process Workflow by a CDE based on the IDM concept
It will simply have to describe how to provide "Common Data Environment" throughout the whole life cycle (horizontal aspect) and throughout the spectrum of management levels and stakeholders (vertical aspect).
In the work item proposed here, all important terms, processes and targets are to be expanded around the CDE concept. Relations to already existing normatives will be given.
Informative attachments such as templates and examples could be provided to the benefit of planner, supplier and operator as further guidelines.
Framework und Implementierung von Common Data Environment Lösungen und Workflow nach EN ISO 19650
Cadre et mise en oeuvre de solutions et flux de travaux pour un environnement de données commun (CDE) conformément à l’EN ISO 19650
Le présent document résume et explique le concept de « solution et flux de travaux pour un CDE », abrégé ci-après par « CDE ». Le concept de CDE est essentiellement défini, mais pas expliqué en détail dans la série EN ISO 19650. En raison de la nature même de la série EN ISO 19650 la définition et l’usage normalisés du CDE décrits dans cette dernière peuvent être trop abstraits pour une mise en œuvre directe. En expliquant le concept de CDE de manière plus détaillée, le présent document sert également de document d’orientation pour sa mise en œuvre.
Ce faisant, le présent document détaille des concepts suivants introduits par l’EN ISO 19650 :
— flux de travaux en tant que processus collaboratif de gestion des informations et des conteneurs d’information ;
— solutions pour soutenir les processus de gestion et de projets inhérents au BIM.
L’archivage et le contrôle de version des conteneurs d’information peuvent devenir très complexes au vu des multiples situations d’information types d’un projet. Des éléments, des règles et une terminologie supplémentaire pour la gestion la numérisation des informations doivent être expliqués et techniquement encadrés dans le contexte d’un CDE. En particulier, le présent document décrit :
— le cadre établi par les concepts faisant partie du concept CDE et s’articulant autour de ce dernier, tel que défini dans l’EN ISO 19650 ;
— la relation entre flux de travaux et solutions en faisant la distinction entre gestion des processus et des entités à l’aide du concept de couches ; et
— le lien entre flux de travaux et solution en utilisant des plans de livraison d’informations
(MIDP et TIDP dans l’ISO 19650).
Le présent document donne ainsi aux participants du marché et aux utilisateurs du CDE des moyens de savoir :
— comment gérer des processus de gestion collaborative des informations selon l’EN ISO 19650 ;
— comment gérer des entités (par exemple des conteneurs d’information tels que des modèles, des exigences, des états de conteneurs) ;
— comment tenir à jour et gérer des documents dynamiques tels que des modèles d’information (AIM pour modèle d’information d’actif, PIM pour modèle d’information du projet) ; et
— comment tenir à jour, échanger et gérer des exigences d’information telles qu’OIR, AIR, EIR ainsi que des plans d’exécution BIM (BEP).
Le présent document identifie l’éventail de termes importants relatifs au concept CDE ainsi que les relations associées aux références normatives pertinentes.
Le présent document est accompagné d’une étude parallèle réalisée par le CEN/TC 442 qui définit l’interface de programmation applicative pour l’interfaçage de la gestion des informations entre plusieurs CDE et solutions CDE. La présente Norme européenne (en cours d’élaboration) intitulée « API ouverte pour le CDE » est élaboré au sein d’un groupe d’étude conjoint réunissant le CEN/TC 442/GT2 et le CEN/TC 442/GT 3.

Introduction
About the normative landscape:
EN ISO 19650 is the framework on collaborative Information Management in BIM. Its first parts were
published in the end of 2018.
To enable the market CEN/TC 442 is delivering various standards and guidelines on some of the concepts
introduced by the EN ISO 19650 series (e. g. EN ISO 7817-1 “Level of Information Need”, CEN/TR 17741
“Guidance to Information Delivery Manual IDM (based on EN ISO 29481), CEN/TR 17654 “Guidance to
EIR/BEP” - cf. Bibliography).
The UK BIM Framework serves as another example on how to enable its market. It is a collaborative effort
from British Standards Institution and NIMA (formerly the UK BIM Alliance) providing guidance on
implementation of the EN ISO 19650 series and on the transition from previous national BIM standards.
This document covers the concept of the “Common Data Environment solution and workflow (CDE)” to
support collaborative Information Management in BIM.
Preliminary work to explain what a CDE is and how it can be implemented has previously been done by
a national initiative within the German mirror committee of CEN/TC 442 in DIN. The result was published
in March 2019 as DIN SPEC PAS 91391 “CDE”.
This document is accompanied by a work item on “Open Application Programming Interface (API)”
defining a technical interface for a CDE. This work is launched in parallel in CEN/TC 442/WG 2.
Enabling market:
The EN ISO 19650 series of standards requires implementers to have at least a base level of
understanding of concepts and options and on how to apply the processes in practice. Market participants
applying and engaging in information management with BIM according to EN ISO 19650 therefore face a
range of approaches. The CDE component is particularly challenging as it is often falsely only considered
to be a technology requirement rather than consistent work process obligation. They can have the option
to manage workflow or include integration of application programming interfaces (API) to various CDE
solutions. Exchanging information containers (cf. EN ISO 19650-1:2018, 3.3.12) and exercising process
management will need a suitable metadata concept. Avoiding inconsistency of deployment from project
to project, from asset to asset requires a functionally sound CDE already at the start of the project. This
document will provide guidance for users. The work item on CDE Open API will provide further details
on how to implement respective interfaces in a CDE solution.
Understanding semantics:
The EN ISO 19650 series provides and defines a collection of new terms, concepts and principles (cf. part
1). At the same time, it also provides rules, requirements and conditions attached to them. The present
Technical Report illustrates the semantics of these elements in a stringent way using a combined schema
notation. The semantic schemata used in this document combine (see figure 1 and figure 2):
— a class diagram according to UML to visualize the entity relationships with (dotted lines),
— a triple graph according to RDF to visualize the process interdependencies (full lines) - while actor-
action-artefact/target can be seen as an specific example of subject-predicate-object.
Key
RDF triple concepts are composed of full lines with the predicate on the line
Directed process/activity
"is part of" relations set definitions
"is type of" relations class definitions

(3.3.12) References to EN ISO 19650-1:2018 are given by the clause number in "normal" brackets.
[3.3.12] References to EN ISO 19650-4:2022 are given by the clause number in squared brackets.
Figure 2 — Example of a combined semantic schema visualizing entity relationship (is type of)
and activity triple (subject-predicate-object/actor-action-artifact, e.g. “party expresses
specification”)
The combination of part of/type of relations with process semantics provides a more holistic view. This
view suits better to understand the combination of information entities and processes managed by the
workflow of CDE.
Workflow concept in the CDE concept:
Workflow is a term being used in the title of clause 12 in EN ISO 19650-1:2018, but it is only superficially
defined within EN ISO 19650 series. There are several ISO based definitions for workflow specific for and
within the environment in which they are being used. Generalizing them results in the following:
Workflow is the main concept hosting processes (see figure 3). Processes are being made up by activities
(reference ISO 12651-2 and EN ISO 9000:2015, 3.4.1). In a way an activity as the basic element of
workflow can be compared with an information container being the basic element of information
management.
Figure 3 — Workflow as a combination of processes composed by activities
Entity concept in terms of CDE:
Entity management in a CDE explained here uses the concept of information container (EN ISO 19650-
1:2018, 3.3.12). It is slightly different to the entity concept used in EN ISO 16739-1. The entity concept in
EN ISO 16739-1 is embedded in an object-orientated environment (model language of ISO 10303-
11:2004). The entity concept in EN ISO 19650 series rather uses entity as a static concept in contrast to
the dynamic concept of a process. Information container used in ISO 19650 and this document can be
understood as a type of an entity in the general semantic meaning of entity.
1 Scope
This document summarizes and explains the concept of “CDE solution and workflow” - hereby
abbreviated by ”CDE”. The concept of CDE is primarily defined but not extensively explained in EN ISO
19650 series. Due to the very nature of the EN ISO 19650 series the standardized definition and usage of
CDE described in the very series can be too abstract for direct implementation. By explaining the CDE
concept in more detail this document will also serve as an implementation guidance.
Doing so this document will detail the following concepts introduced by EN ISO 19650:
— workflow as a collaborative process of managing the information and information containers,
— solutions to support the management and project processes inherent for BIM.
Archiving and versioning of information containers can become very complex when considering various
typical information situations of a project. Further elements, rules and terminology for information
management and digitisation needs to be explained and technically framed in the context of a CDE. In
particular this document describes:
— the framework established by the concepts in and around the CDE concept of EN ISO 19650,
— the relation between workflow and solution by differentiating between process and entity
management using the layer concept and
— the connection between workflow and solu
