Enterprise Architecture (EA) Glossary of Terms

This page presents the full Glossary of Terms of the Dragon1 open EA Method. This is the official source. In Dragon1 definitions of concepts are taken very seriously. All the terms are related in the Dragon1 Meta Model. An EA Glossary with the top 50 most important terms can be found here.

The Dragon1 Glossary becomes available in 2019 in the following languages: English, Chinese / Mandarine, Hindi, Arabic, French, German, Spanish, Portuguese, Dutch, Russian, Bahasa Indonesia, Japanese and Korean. To participate,please read the Contribution and Revision History here. They also contain the icon design guidelines.

Writing Good Definitions

Writing good definitions is a hard task. In Dragon1 we stay close to three rules for good definitions: Does the definition only uses previously defined terms?, Does the definition quantify and qualify?, Are there any counter examples for the definition?

If you have comments or remarks about terms or definitions, please mail to specs@dragon1.com.
