Chapter 2: Before you begin

Questions

Matthias Sesboüé

Can you give an example of how to proceed when we want to reuse only a sub-part of an ontology (or of a module of an ontology). Should we manually extract the part of interest or recreate our own definitions?
Section 2.4 in the model-centric perspectives, I am not sure I understand the second bullet (at the top of page 22). What do you mean by "passive" and "active" structure?
Section 2.7, language selection, can you give some examples of different languages and their specificities?

Section 2.1, how familiar should an ontologist be with the ISO standards related to terminology, such as ISO 704:2009, and ISO 10241-1:2011?
Section 2.2, Modeling and Levels of Abstraction, the four layers proposed for a financial application, have either of the authors mapped these to the framework shown in figure 2.1?

Section 2.3, You mention here that it is recommended to re-use standardized, well-tested, and available ontologies whenever possible. This prompted me to look for a way to find existing ontologies. Is there a robust search tool or directory to find examples of well-tested ontologies that already exist?

Near the end of the first paragraph on page 19 you use the word "actors" in a way that's not entirely clear to me. Can you elaborate? The full sentence reads "Information elements should be represented as actors in those use cases."
