Tools Suite Technologies

Introduction

This document lists the libraries we use in the ODK 2.0 tools.

The active list of 3rd party libraries can be found in the libs directory.

For rev 126/7 and earlier, this is under:

framework/libs

For later releases, this is under:

system/libs

At this time, these are:

chai -- testing framework for Tables Javascript
d3 -- graphics library
jquery-mobile -- widgets and layout designed for mobile devices (replaced by bootstrap after rev 126/7)
jquery-csv -- for reading CSV files for external datasets
jquery-qrcode -- for reading and generating QRCode barcodes
mobiscroll -- for date and time widgets (removed after rev 126/7)
mocha -- testing framework for Tables Javascript
backbone -- for class inheritance; we have our own custom persistence layer
d3_chart_box -- extension to d3 for charting
handlebars -- templating framework for all HTML rendering
jquery -- utility library (may be replaces with zeptos or other lighter frameworks in the future)
require -- module dependency and loading framework
text -- extension to require for loading plain text files (vs. javascript). Used to dynamically load handlebars template files.
underscore -- utility library
XRegExp -- utility library for extended regular expressions supporting UTF-8 patterns.

Some of our Tables demonstration forms have been using ratchet

On the devices, we make use of a wide variety of libraries. These will be in the libs directories of the various projects.

The key technologies that drive the inclusion of many of these libraries are:

Jackson2 JSON and XML serialization library. This is used in our REST synchronization interface with the server. It is also used in most places internally, though there are some GSON and JSON library usages.
Wink REST client. This is a stripped-down version of Wink, a REST interface library. We use Wink on the server and client, with only Javascript transport to the client (while the server can speak XML, the client only speaks Javascript). This client uses URLConnection internally.
Apache Http Client 4.2 custom build. This (httpclientandroidlib) library is used only by the legacy 1.x pipeline.
KXML. We are using the Android-supplied version of this after rev 126/7. For rev 126/7 and earlier, this is a hold-over from a 1.x Javarosa library dependency.

On the server, we are using a considerable number of libraries. You can see the list by browsing to
