This glossary has been manually created to enable ToIP WGs and TFs to use eSSIF-Lab terminology in their texts.

Every entry in the glossary is structured as follows:

• Header line that shows a term (which you can click to get more in-depth information), and (at the right) a tag representing the scope(s) in which the term is defined/used.
• The subsequent line(s) state its definition as defined for eSSIF-Lab. This definition typically uses other terms defined in this terminology.

• Clicking on the left icon (two shackles) copies a hyperlink to the glossary entry to the clipboard. You may use this in your own texts to refer to the definition of this term.
• Clicking on the right icon (rounded square with exiting arrow) navigates to the location where the sources of the definition lives on github. This is intended for people that want to contribute to the eSSIF-Lab terminology
