+## Representation in JSON-LD
+
+Semantic form is structure that holds a form (set of questions) as well as its data (set of answers). 
+A conceptual model of Semantic forms is [questions/answers model](https://kbss.felk.cvut.cz/gitblit/summary/s-forms-model.git).
+The conceptual model is described in RDF language. This library processes and generates Semantic forms using JSON-LD
+format which is JSON compatible serialization of the RDF language.
+
+## Development 
 
 Building SForms library can be done using `npm run build:lib`.

 Rendering of a form can be easily tested through sample react application provided in `./test` folder. The application can be  started by executing npm script through `npm run dev` and then accessing `loaclhost:8888` from a browser. It renders the form provided by the file `./test/rendering/form.json`. See `./test/rendering/TestApp.jsx` for more details.
