+\glspl{Task} were only looking at parts of the structure that was not updated.
 To solve this problem, parametric lenses were
 introduced~\cite{domoszlai_parametric_2014}.
 
 Parametric lenses add a type variable to the \gls{SDS} that is in the current
-library functions fixed to \CI{()}. When a \gls{SDS} executes a write
-operation it also provides the system with a notification predicate. This
-notification predicate is a function \CI{p -> Bool} where \CI{p} is the
-parametric lens type. This allows programmers to create a big share, and have
-\glspl{Task} only look at parts of the big share. This technique is used in the
-current system in memory shares. The \CI{IWorld} contains a map that is
-accessible through an \gls{SDS}. While all data is stored in the map, only
-\glspl{Task} looking at a specific entry are notified when the structure is
-updated. The type of the parametric lens is the key in the map.

 Functionality for setting parameters is added in the system. The most important
 function is the \CI{sdsFocus} function. This function is listed in
 Listing~\ref{lst:focus} and allows the programmer to fix the parametric lens to
