Shift – Driven by Customer Expectations
• One of their customers paid a consultant to build a mobile app for delivering lab
results to patients
• Built on a collection of existing web services in Shift’s solution
• Shift realized they needed to provide this functionality to all their partners
• Approached InterSystems in August last year about using Zen Mojo to deliver this
• Full development effort started in the winter of 2014
• The scope of the project later expanded to cover most of their current application
• Beta in summer 2014 with go lives at their launch sites underway

Building a Mobile App
• Different challenges to building for a desktop environment
– Device orientation
– Single touch and multi-touch events
– Access to the device hardware may be required
– Low bandwith or OFFLINE mode
– Some desktop events aren‘t supported (i.e. MouseOver)

What is the Mobile “toolkit” for InterSystems Technology ?
• RESTful interfaces
• Zen Mojo
You’ll make breakthroughs
RESTful Interfaces
• Representational State Transfer – a set of architectural principles that describe
web services as an alternative to SOAP and WSDL based design
• Stateless, use HTTP methods explicitly (POST, GET, PUT, DELETE)
• Expose directory structure-like URIs
• Independent of transport mechanism (JSON, XML or both)
• Were always implementable using CSP but formal support was added in 2014.1
• Some REST capabilities added to Ensemble in 2013.1

JSON – JavaScript Object Notation
• Open standard data interchange format
• Originally specified by Douglas Crockford in RFC4627 written in 2006
• Designed to be human readable and easy to parse
• Derived from JavaScript for representing simple data types and associative arrays
• Language independent, JSON parsing and generation has been implemented in
many languages
• Two data structures – Object and Array
• InterSystems core support
• jsonProvider
• jsonSQLProvider
• proxyObject

Zen Mojo
Framework for simplifying application development
Android and iOS
Leveraging the best tools on the market for UI
You’ll make breakthroughs
Zen Mojo
• Single Page Architecture
• Server transmits JSON data that drives the page layout and page content
• Page transitions handled by changing the underlying layout and content data and
• Page rendering is handled by plug-ins, typically third party libraries but could be
user written code
You’ll make breakthroughs
Single Page Architecture
• Efficient approach for reducing client-server communication
• Page consists of a sparse HTML skeleton implementing a rendering method
• Display can be changed by updating the metadata and calling the rendering
method – no page transition
• Metadata transmitted as JSON objects
You’ll make breakthroughs
• Mojo uses a plug-in architecture for easy, rapid integration of state-of-the-art
JavaScript libraries
• New UI paradigms can be adopted as soon as they are supported by a new
• PageManager plug-in – creates an application shell that contains the application
content and manages page transitions within the Single Page Architecture
• Helper plug-ins – add support for positioning and rendering objects that can be
defined in the page data
You’ll make breakthroughs
JavaScript Libraries for Mobile Web Apps
• There are many JavaScript libraries available for building mobile web apps
• jQuery Mobile for building a cross platform custom look-and-feel
• ChocolateChip UI provides components and style sheets that emulate the lookand-feel of iOS, Android and Windows Phone devices
• Also support HTML5 and Google Maps plug-ins
• By default Mojo web applications are deployed on a server and require
connectivity from the mobile device at startup time
You’ll make breakthroughs
Building Hybrid Mobile Apps
• Web application runs inside a native container
• PhoneGap based on Apache Cordova is an example container – open source
framework using standardized device APIs (accelerometer, camera, geolocation,
• Mojo allows an application bundle to be compiled and packaged
• Application bundle can be run locally
• Application bundle can communicate with a server but server connectivity is not
required at startup

Desktop Too ?
• Plug-in approach allows integration of libraries for building rich desktop
applications using the same architecture
• Dojo Toolkit is the suggested library

ZEN Mojo Architectural Overview

Text text
1. ZEN Mojo page compiled on the server
2. Device requests page via browser
3. Server sends ZEN Mojo page to client
4. Data/Layout requests are communicated between client/server
You’ll make breakthroughs
Developing a ZEN Mojo App
• Caché or Ensemble
• A PhoneGap installation (
• A copy of jQueryMobile ( or
ChocolateChip-UI (
• SDK for the target device platform
• You have to setup a specific development environment for each platform if you
want to build PhoneGap apps locally
– Eclipse /Java for Android
– Mac OS X and Xcode for IOS
– .NET for Windows phones
– See PhoneGap docs for more platforms
• PhoneGap Build Service available
