 # LatticeJSON
 
-LatticeJSON is a JSON based lattice file format. JSON is able to describe complex data structures,
-has a human readable syntax and is available in all common programming language. It is therefore an
-appropriate choice to characterize the magnetic lattice of a particle accelerator.
+LatticeJSON is a generic lattice file format based on JSON. As different lattice files have program-specific elements and attributes a 1:1 translation between them is not always possible. A 1:1 mapping can be achieved by defining restricted versions of common latticefile formats, where only generic elements are allowed. Than lattice files in different formats can be generated from a single "ground truth" lattice file, where LatticeJSON is used as intermediate representation.
+
+LatticeJSON does not provide any variables or syntax to reverse or multiply sequence of elements, because it is intended to be generated by a tool. It can be thought of as a (flattened/evaluated) lattice files.

+LatticeJSON tries to provides an intermediate repres restricted versions of common lattice file formats. JSON is able to describe complex data structures,has a human readable syntax and is available in all common programming language.
