The central term when it comes to storing data in everarch is ’claim’. You can think of claims as statements like ’roses are red’ coded in XML so computers can interpret them easily.
<thing-color xmlns="https://my.domain/my-claims" thing="rose" color="red"> Lately I was wandering through the garden and observed that roses are actually red. </thing-color>
Everarch is storing these claims and can index them for finding them later.
