An Overview

With the aim of making app development as easy as possible, the DS pre-defines a set of concepts we called system concepts. These concepts are just like other normal concepts except they are so frequently referenced that it is definitely a good idea to define them in advance in order for app designers to effortlessly reference them instead of writing them themselves.

A system concept is either a system entity or a system phrase. Some examples of system entities are "color"---which could be green, blue, or red---or "number"---which could be a 1, 9, or 100. An example of our predefined system phrases is "base.phrase.greeting.niceToMeetYou"---which could cover the phrases,

nice to meet you
great to meet you
good to see you
, etc.

You get the idea.

One can refer a system entity or system phrase simply by typing an @ while defining a sentence under the intents tab.
