 For example our description of the term _software architecture_ can be referenced (hyperlinked) with

+ `https://public.isaqb.org/glossary/glossary-en.html#term-software-architecture`
 
 Nearly all terms are hyperlinked with their full names, with very few examples that  are referenced by their (common) abbreviations, like UML or DDD.
