JSON-RPC API - HTML5, Javascript and WebSQL

Hey! I have a PDF-File with the JSON-RPC API of WebUntis. What is WebUntis? WebUntis is a time-tabling platform for students. Schools can manage their timetable with "Untis" Software and publish the data to WebUntis. Students can log in their account and view their upcomming courses. So I have a API for this service. I want to make an alternative of WebUntis for a Webapp. So I need someone who have knowledge with JSON RPC (for dealing with the API) and is expert in Javascript/HTML. You can see the API as an attachment of this project. FEATURES 1) Login User can login to the WebUntis with their login details over the API. The User have also to select the Server and School. (WebUntis have different schools on different servers. The user know the Server of their school.) form Username: input field Password: password field Server: listbox field (a list with the servers) School: input field The form has to send to the API. The API checks the data. The login has to be stored in a WebSQL Database. The user has to log in automatically on page load if the login is in the database. 2) Timetable WebUntis provides a individual timetable of the User. You have to read the data and display is in html (time, subject, teacher, room) The User can can switch between weeks an days. 3) Courses All Courses (subjects) have to be stored also in a WebSQL Database. Just import it from the API. And output on a html page. 4) Teachers All Teachers have to be stored also in a WebSQL Database. Just import it from the API. And output on a html page WebUntis Online demo version The online demo version of WebUntis you can find here: [login to view URL] User is 'student'. You need no password. I can also provide my personal login for testing. It's with a password. Each user have different login details: server and school. In demo the server is: [login to view URL] school: demo_inf user: student no password So you have to build a webapp with html/jquery and websql which deals with the WebUntis API and have the noted featues 1 - 4.
