3 Non-geometry standards
Chapter 3 explains all ISO 19100 standards apart from ISO 19101 (Reference model)
and the geometry-oriented standards that are ISO 19107 (Spatial schema), ISO
19123 (Schema for coverage geometry and functions), ISO 19125-1 (Simple feature
access - Part 1: Common architecture), and ISO 19136 (Geography Markup Language). The ISO 19101 is explained in chapter 2. The other four standards are explained in detail in chapter 4.
3.1 Infrastructure standards
The infrastructure standards set rules that apply to all pieces of the ISO 19100
family. They define the "infrastructure" for the development of the standards themselves and for the development of application schemas and profiles. The infrastructure standards incIude the conceptual schema language (lSO/TS 19103), the tenninology (ISO 19104), the confonnance and testing (ISO 19105), and the profile (ISO
19106). Originally, the ISO 19102 (Overview) was meant to provide a general introduction to the ISO 19100 family. The project was later cancelled because it was difficult to continuously update it while standards evolved. The Internet and textbooks
such as this, may provide a much better access to the ISO 19100 standards.
3.1.1 Conceptual schema language (ISOfTS 19103)
Today, if experts meet to discuss the design of a computer system they would talk
in a conceptual schema language. Admittedly, they speak in English, French, or
Gennan, or any other language of the world, but a conversation like this remains infonnal and fuzzy until someone starts drawing a diagram, mostly in UML, the Unified Modelling Language, in order to express the ideas with the fonnal tools of
cIasses or packages and their relationships. Therefore, it is essential for everybody
who works in this field to be able to communicate in a conceptual schema language.
The ISO/TS 19103 (Conceptual schema language) defines a UML profile for geographie infonnation. This book assumes the reader has abasie knowledge of UML
and focuses on the extensions ofUML for geographie infonnation.
