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 member 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 document 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).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 287, Geographic Information, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 19103:2015), which has been technically revised.

The main changes are as follows:

conformance to UML 2.5.1 has been improved;
- the UML profile has been improved and the stereotypes Leaf, CodeList and Union have been deprecated;
- the collection data types, the name data types, the extension data types and data type Any have been removed;
alignment with the data types described in ISO/IEC 11404:2007, Clause 8 and Clause 10 has been improved;
the conformance classes for conceptual schemas modelled in UML 1.x and for conceptual schemas modelled in another conceptual schema language have been removed;
the normative references have been updated, in particular:
- addition of UML 2.5.1 and removal of ISO/IEC 19505‑2:2012 (equivalent to UML 2.4.1, Superstructure^[⁴^]);
- removal of the Object Constraint Language (OCL) specification.

Introduction

This document is concerned with the adoption and use of a conceptual schema language (CSL) for developing computer-interpretable models, or schemas, of geographic information. Standardization of geographic information requires the use of a formal CSL to specify unambiguous schemas that can serve as a basis for data interchange. An important goal of the ISO 19100 family of documents is to create a framework in which data interchange and service interoperability can be realized across multiple implementation environments. The adoption and consistent use of a CSL to specify geographic information is of fundamental importance in achieving this goal.

There are two aspects to this document. First, a CSL is selected that meets the requirements for rigorous representation of geographic information. Several CSLs exist, of which two predominate in the geographic domain: the Unified Modeling Language (UML), specified by the Object Management Group (OMG), on the one hand, and the combination of the three Semantic Web specifications, the Resource Description Framework Schema (RDFS), the Web Ontology Language (OWL) and the Shapes Constraint Language (SHACL), specified by the World Wide Web Consortium (W3C), on the other hand. It was decided to continue using UML as it has proven its capability within the ISO 19100 family of documents, it supports a model-driven approach and it has a standardized graphical notation. This document identifies a subset of UML as the CSL for the specification of conceptual schemas. It also specifies a UML profile for the specification of conceptual schemas, and it specifies provisions on how to use UML and the UML profile to create conceptual schemas that are a basis for achieving the goal of interoperability. In addition, this document defines a set of core data type definitions for use in conceptual schemas.

One goal of the ISO 19100 family of documents using conceptual schemas specified in UML is that they will provide a basis for model-based mapping to encoding schemas like those defined in ISO 19118, as well as a basis for creating implementation specifications for implementation profiles for various other environments.

This document describes the general metamodel for the use of UML in the context of ISO geographic information documents. Aspects specifically dealing with the modelling of application schemas are described in ISO 19109.

In accordance with the ISO/IEC Directives, Part 2, 2021, Principles and rules for the structure and drafting of ISO and IEC documents, in International Standards the decimal sign is a comma on the line. However, the General Conference on Weights and Measures (Conférence Générale des Poids et Mesures) at its meeting in 2003 passed unanimously the following resolution: “The decimal marker shall be either a point on the line or a comma on the line.”^[⁵^] In practice, the choice between these alternatives depends on customary use in the language concerned. In the technical areas of geodesy and geographic information it is customary for the decimal point always to be used, for all languages. That practice is used throughout this document.
