Modules and applications for the voozanoo ecosystem
Wepi - The web questionnaire tool for epidemiologists and health professionals
This application (www.wepi.org) allows a non-technical person to create web questionnaires and share the task of entering data among any number of individuals that he/she wishes.
Additionally, Wepi is compatible with Open Data Kit allowing an individual to fill out questionnaire forms on an Android tablet or phone.
Graphical or textual (not shown) user interface for questionnaire creation
Share your questionnaire in one of three modes: Surveyor, individual, or by URL.
Questionnaires can include GPS coordinates.

EpiFiles - ASIP certified secure file exchange application
EpiFiles (www.epifiles.com) is an application for exchanging nominative health related files among health professionals such as laboratories and health care providers. See the video presentation here.
Users of this application conform with national requirements and regulations for transmitting personal health information between health professionals. It is a straigh-forward way to handle file exchanges of large quantities and sizes.

Budi - Task scheduler
BuDi stands for Bulk Dispatcher. It takes loosely organised files from application A and sends then to application B. The latter is typically the one that processes the received data, pulling them into a database for example. The frequency of pickup and dispatching is determined by the administrator who sets the execution time. All the events that transpire (pickup, sending, task success, task failure) are logged and certain ones are sent as notifications to the task creator. It is possible to attach a script to the data when it is being sent to the receiving application. The roll of this script is to tell the recieving application what it must do with the data. All data routes are secure and thus require authentification, be it on the file pickup or on sending.
A BuDi pilot has been integrated natively into EpiFiles which allows it to be either a source or destination of files. The combination of BuDi and EpiFiles could for example be used to get data files from the field (in csv, xml, or other) and then transmit them via BuDi at regular intervals to a third party application which centralises all the data.

MailMerge - web application & service
MailMerge (mailmerge.voozanoo.net) is a web application as well as a web service allowing Voozanoo 3 (standard configuration), Voozanoo 4 (Zend-based configuration) and other applications to generate PDF documents based on data files. You can use two types of templates. Either create a document with a word processor and put tags within the sentences where you want specific data to appear (this is the Microsoft Word method), or by pulling in an existing PDF document and placing the tags on top of it at specific locations.
The web service allows a third party applications to pilot MailMerge in order to create documents in a manner transparent to the users.
Create the model with the built-in editor.
Upload a pdf file as the model and overlay your variables at the desired location.

Open Data Kit - off-line data collection on a tablet or smartphone
For data collection in the jungle or on the street, Open Data Kit (ODK) was designed to work off-line. Once the questionnaires are saved to the device, the data collection begins. You don't need an Internet connection until you want to send your collected information back to your Voozanoo application. You can include the geo-coordinates o f where the data was collected in the questionnaire in order to later visualise the results on a map. ODK is an open source application created by the computer science department of the University of Washington.phone.
One or multiple questions per screen
Questionnaires can include GPS coordinates.
R Statistics & Reporting - web application & service
Over its 22 years of existance, the R programming language and environment for statistical computing and graphics has become a formidable alternative to commercial statistics applications. The R Voozanoo module relies on a dedicated and secure R server. As a web service, it allows a Voozanoo application to create high quality graphical representations of data as well as apply advanced mathematical analysis to the data. R is an open source language used by over 200,000 people and includes hundreds of contributed libraries for just about any professional endeavor. EpiConcept has created its own library of special commands and analyses in the field of epidemiology.

SSO Portal - secure access to multiple applications
SSO (Single Sign on) is the technology that allows separate applications to share a single authentification step. When a user logs into his Voozanoo application, the SSO module assures that the supporting web applications (modules) are aware that the user has the right to use these other modules as well as access data from the Voozanoo application or write to it. This module allows for the centralisation of users, rights, and access managment to the applications. Included with this is a strong authentification protocol which requires users to insert a smart card (with built-in certificate) into a reader device connected to the computer and enter the card's secret code.
Single Sign On is transparent, it just works.
