Information container for linked document delivery - Exchange specification - Part 1: Container (ISO 21597-1:2020)

This document defines an open and stable container format to exchange files of a heterogeneous nature
to deliver, store and archive documents that describe an asset throughout its entire lifecycle.
It is suitable for all parties dealing with information concerning the built environment, where there is
a need to exchange multiple documents and their interrelationships, either as part of the process or
as contracted deliverables. The format is intended to use resources either included in the container
(such as documents) or referenced remotely (such as web resources). A key feature is that the container
can include information about the relationships between the documents. Relevant use-cases reflect the
need for information exchange during the entire life cycle of any built asset and can include, but are not
limited to, the handover of
1. a published bidding package,
2. required project deliverables at a specific project stage (e.g. when proposing different design
scenarios),
3. shared information as background or for further development,
4. published approval packages, or
5. information about versions between partners to provide a means to reference particular states of
the information and track changes.

Informationscontainer zur Datenübergabe - Austausch-Spezifikation - Teil 1: Container (ISO 21597-1:2020)

Dieses Dokument definiert ein offenes und stabiles Containerformat für den Austausch von ansonsten nicht zusammenhängenden Dateien, um Dokumente, die einen Vermögensgegenstand während seines gesamten Lebenszyklus beschreiben, zu liefern, zu speichern und zu archivieren.
Es ist für alle Beteiligten geeignet, die sich mit Informationen befassen, die die gebaute Umwelt betreffen, wenn die Notwendigkeit besteht, mehrere Dokumente und ihre inneren Bezüge entweder als Teil des Prozesses oder als vertraglich vereinbarte Ergebnisse auszutauschen. Das Format ist dafür vorgesehen, Ressourcen zu verwenden, die entweder im Container enthalten sind (wie z. B. Dokumente) oder auf die extern verwiesen wird (wie z. B. Web Ressourcen). Ein Hauptmerkmal besteht darin, dass der Container Informationen über die Beziehungen zwischen den Dokumenten enthalten kann. Die relevanten Anwendungsfälle spiegeln den Bedarf für den Informationsaustausch während des gesamten Lebenszyklus eines baulichen Assets wider. Sie können nachfolgend genannte Informationsbereitstellung einschließen, sind jedoch nicht allein darauf beschränkt:
1) Übergabe eines veröffentlichten Ausschreibungspakets;
2) Übergabe geforderter Projektergebnisse in einer bestimmten Projektphase (z. B. wenn verschiedene Planungsvarianten vorgeschlagen werden);
3) Übergabe gemeinsamer Informationen als Grundlage oder für die weitere Entwicklung;
4) Übergabe veröffentlichter Genehmigungspakete; oder
5) Übergabe von Informationen zu Versionen zwischen Partnern, als Mittel für die Referenzierung bestimmter Informationsstände und für die Nachverfolgung von Änderungen.

Conteneur d'informations pour la livraison de documents liés - Spécification d'échange - Partie 1: Conteneur (ISO 21597-1:2020)

Le présent document définit un format de conteneur ouvert et fiable permettant d'échanger des fichiers de nature hétérogène afin de livrer, de stocker et d'archiver des documents qui décrivent un bien tout au long de son cycle de vie.
Il est adapté à toutes les parties traitant d'informations relatives à l'environnement bâti, lorsqu'il est nécessaire d'échanger plusieurs documents et leurs relations mutuelles, soit dans le cadre d'un processus, soit en tant que livrables sous contrat. Le format est destiné à utiliser des ressources soit intégrées dans le conteneur (telles que des documents), soit référencées à distance (telles que des ressources Web). La possibilité d'inclure dans le conteneur des informations sur les relations entre les documents le composant, constitue une caractéristique majeure. Les cas d'utilisations pertinents témoignent de la nécessité d'échanger des informations tout au long du cycle de vie des biens bâtis et peuvent inclure, de manière non exhaustive, le transfert:
- d'un dossier d'appel d'offres publié;
- de livrables exigés à une étape spécifique d'un projet (p. ex. lors de la proposition de différents scénarios de conception);
- d'informations à caractère général partagées ou destinées à un développement futur;
- de dossiers d'approbation publiés; ou
- d'informations sur les versions entre les partenaires pour fournir un moyen de référencer des états particuliers de l'information et le suivi des modifications.

ISO 21597-1:2020(E)
Introduction

The ISO 21597 series has been developed in response to a recognized need within the construction

industry to be able to handle multiple documents as one information delivery.

Information deliveries are often a combination of drawings, information models (representing built

or natural assets in the physical world), text documents, spreadsheets, photos, videos, audiofiles, etc.

Increasingly, this may also include datasets based on any ontology. An ability to specify relationships

using links between information elements in those separate documents can contribute significantly

to the value of an information delivery. The composition of such a package arises both from the

requirements of the process, e.g. delivery of as-built information, and from the specific functional

purpose e.g. performing a quantity take-off or communication about issues in 3D models.

In this document a specification is given for a container that stores documents, along with a means of

linking otherwise disconnected data within those documents.

The container format includes a header file and optional link files that define relationships by including

references to the documents, or to elements within them. The header file uniquely identifies the

container and its contractual or collaborative intention. This information is defined using the RDF,

RDFS and OWL semantic web standards.

The header file, along with any additional RDF(S)/OWL files or resources, forms a suite that may be

directly queried by software. The link references may be interpreted by the recipient applications or

reviewed interactively by the recipient. Where it includes link references into the content of documents

that don’t support standardized querying mechanisms, their resolution may depend on third party

interpreters.
The format can also be used to deliver multiple versions of the same document.

Note 1 to entry: The definition is adapted from W3C-RDF11-XML.
3.1.14
resource

something in the world (the "universe of discourse") denoted by an IRI or literal

Note 1 to entry: Anything can be a resource, including physical things, documents (3.1.3), abstract concepts,

numbers and strings; the term is synonymous with "entity" as it is used in the RDF Semantics specification.

3.1.16
individual

resource (3.1.14) that has been placed into any RDFS class (3.1.15) as an instance of that class

Note 1 to entry: Like RDF classes, every OWL class is associated with a set of individuals, called the class

extension; the individuals in the class extension are the instances of the class.

Note 2 to entry: There are two types of individuals in the syntax of OWL 2. Named individuals are given an

explicit name that can be used in any ontology (3.1.7) to refer to the same object (3.1.23). Anonymous individuals

do not have a global name and are thus local to the ontology in which they are contained.

NOTE IRI is an update of the URI released in 2005; while URIs are limited to a subset of the ASCII character set,

IRIs can contain characters from the Universal Character Set (Unicode/ISO/IEC 10646). In the ISO 21597 series

URIs and IRIs are used interchangeably.
4  Specifications
4.1 Use of RDF, RDFS and OWL constructs

All ontologies held in containers that conform to the ISO 21597 series shall be based on the languages

RDF [W3C-RDF11-CONCEPTS], RDFS [W3C-RDF11-SCHEMA] and OWL [W3C-OWL2-SPEC] (referred to

collectively in the ISO 21597 series as RDF(S)/OWL) and shall be serialized in RDF/XML [W3C-RDF11-

XML] or any other equivalent RDF serialisation recommended by W3C.

It is expected that RDF(S)/OWL will be an important technology and a general platform for ontologies

for the coming decades. Proprietary systems will increasingly adopt RDF(S)/OWL. However, to make

the threshold for adoption of this document as low as possible, Annex C provides specifications to

support the conversion of a container from RDF(S)/OWL to XSD/XML and vice versa.

In general, when used in the context of the world wide web, these languages use the following principles

to support reasoning:

— Open world assumption - the truth of a statement is independent of whether it is known. In other

words, not knowing that a statement is explicitly true does not imply that the statement is false.

— No unique names assumption - unless explicitly stated otherwise, it cannot be assumed that

resources that are identified by different URIs are different.

The datasets that comply with the ontologies specified in the ISO 21597 series shall use the following

interpretation of RDF(S)/OWL:

— Closed world assumption - a statement that is true is also known to be true; therefore, conversely,

what is not formally specified in a container to be true, is false.

— Unique naming assumption - resources in a container that are identified with different URIs are

considered to be different, unless explicitly declared as the same (using the owl: sameAs predicate).
