Session 2: Mobile Data Collection
========================================================

*Election observation, Cairo polling station, May 24, 2012.*
Data Collection Goals
==================================
Ideal features of data collection:
* Standardized
* Ease of collection by researchers
* Ease of survey use by participants
* Flexibility with types of data samples
* Data security
Common Data Collection Problems
====================================
* Consistency between form or survey data and database structure
* Transcription or legibility errors between data collection and database storage
* Forms may need to be updated or changed
* Literacy or language barriers with written surveys
* Extra equipment needed to collect non-text data
* Secure data transfer and storage
Open Data Kit
========================================================
left: 50%
Open Data Kit is an open source tool for solving many data collection problems. It consists of:
* An Android tablet or phone and app for data collection
* A server instance to store and view collected data
* Powerful form and survey creation

ODK Solutions: Secure Data Collection
=======================================
ODK Collect is designed with security in mind...
* Data transmission to the server is encrypted with SSL
And in our department, with our own ODK Aggregate server ...
* Access to the ODK server is protected by a firewall
* Each ODK project has a unique database instance
* Each database instance has a unique account and password
* The ODK server is regularly updated and backed up
* The ODK server is in a secured room with auxilliary power
ODK Solutions: Several Data Types
=======================================
Collecting data on a phone or tablet allows for the following data types to be collected:
* Text
* Images
* Video
* Audio
* GPS coordinates
* Barcode scanning

ODK Solutions: Powerful Forms
=======================================
Forms are powerful and flexible, for example:
* Alternate languages for survey questions
* Audio, image, and video components to questions
* Branching question paths:
If A1 is 'yes', show Q2
* Calculations on answered questions: Q3 = A1 + A2
* Multiple choice questions: single or multiple answer
* Repeatable question sections
* Automatic meta data, such as survey start and end times
ODK Demos...
========================================================
We will now demonstrate:
* ODK Collect (app)
* ODK Aggregate (server)
* ODK Form Creation

ODK Form Creation Demo
========================================================
There are three ways to make data input forms for ODK:
1. Using [ODK Build](http://build.opendatakit.org/) web app
2. Manually, by editing an [XML file](http://opendatakit.org/help/form-design/) in a text editor
3. Using [XLSForms](http://opendatakit.org/use/xlsform/) from a Spreadsheet (XLS)
