Advanced Coding Projects

Projects for more experienced coders.

Some things to keep in mind when planning new modules or major features:

• Consider what other FOSS tools exist, that could be installed alongside Eden.
• Look at tools and libraries already in use in Eden, e.g. jQuery and ExtJS for UI work.

GIS/Mapping

These are a number of GIS/Mapping Tasks to be done:

• complete support for Mobile devices
• complete move of Intertnal Feature Layers to GeoJSON
• complete moving of JS code from being generated server-side to [static http://eden.sahanafoundation.org/browser/static/scripts/S3/s3.gis.js] (for caching & easier maintenance)
• integrated Legends in the West Panel (see GeoExplorer or ​http://api.geoext.org/1.0/examples/legendpanel.html)
• complete migration to GeoExplorer
• OpenStreetMap PoI Layers
• Color coded maps according to Geo-data (threats, needs, etc)
• Placing variable sized markers on the map in proportion to data (number of people in camp, number of families needing food)
• Tracking people ( John Smith was registered at Camp A, then collected food at Camp B, then volunteers at Site C), or Items (The shipment of Tarpaulins moved from site C to site D, where it was split, and then half of them have been distributed from site E)
• Having a playable timeline slider (like ​http://haiti.ushahidi.com/main)
• Photo Bulk Uploader
  • Add EXIF support to geolocate images
  • Provide opportunity to add Metadata for all files
  • Add support for GPX Track timestamp correlation
• More: BluePrintGeographicInformationSystems

Wikipedia Locations

Allow Sahana to import Wikipedia locations easily: both Hierarchy & Lat/Lon info

• Probably more about work in Wikipedia/Geohack to get these stored in a strctured way & an API to extract the data.
• Similar need to: ​http://wiki.rhok.org/Population_Centers_in_Disaster

Fix Web2Py Cron on Win32 Service

Web2Py has a nice Cron utility, but this doesn't work currently on Win32 in Service mode: #438

Framework

• Provide localisation of jquery.ui.datepicker
  • Means that user profile will need extending to support locales
• Replace jquery.autocomplete.js with jquery.ui.autocomplete.js (1.8.2)
• Replace jquery.cluetip.js with jquery.ui.tooltip.js (1.9 once released)
• Decorator to restrict access to a function based on multiple roles
• Improve UI for Many<>Many
  • e.g. Admin Users/Groups
  • e.g. GIS Layer Catalogue (esp FeatureClasses/FeatureGroups)
  • e.g. Messaging Users/Groups

Test Automation

• Write Functional Tests using Selenium
• Figure out how to do unit tests against a web application.
  • Write unit and functional tests.

Tweet / SMS Parsing

Allow users to provide info via tweets or SMS messages

• Parse formatted SMS messages or tweets (e.g. key value pairs).
• Detect when message interpretation isn't certain and dispatch to a human reader (use existing "task" database, or Job Jar, below!).
• Create database records from parsed messages.
• BluePrintMessagingModule#Twitter
  • NCSU Students working on this
• BluePrintMessagingModule#Micro-Syntax

Mobile Photo/Video Upload

• Design a widget (to be included in an Eden form) that can be used to select images or video, with any needed detection of the type of phone.

Run Eden on a smart phone

• See BluePrintMobileClient.
• Alternate Layout for web view: BluePrintCSS
  • NCSU Students working on this
• Android Application: MobileAndroid
  • NCSU Students working on this

Chat in Sahana

With other logged in users

• Provide a chat board through which users can help each other or get help from the system administrator.
• Perhaps have one chat for each organization or project.
• Is there existing IRC or other chat software that could be incorporated?

Survey Application

The survey module was started during GSoC this summer. The author will be online on freenode #sahana-ghc under the nicknames robbyoconnor or r0bby|android during the Codeathon.

• Change it so that it uses "components" to relate survey sections to the survey, and questions to the survey sections.
• Please keep in mind that the survey tool should be able to support question data types (defined in the user guidelines)
• Ideally, the look and feel of the surveys should be modeled after the Rapid Assessment Tool (rat) module. (See models/rat.py and controllers/rat.py to get an idea of what needs to happen.)
• We are aiming to allow non-technical users to create surveys similar to what was done in the rat module.
• Additional Resources: User Guidelines
• If this project is undertaken, please update the wiki documentation to match.

OCR

Optical Character Recognition

• Integrate an OCR tool developed for GSoC into Eden.

New Use Cases

Extensions to support:

• Organizations such as ​Ten Thousand Villages assist craftspeople in disadvantaged countries organize to purchase supplies and market their crafts. What would such a crafts coop need to help run their business? What's missing from Eden to support this?
• ​Maitri provides support to victims of domestic violence.
  • They have a ​page listing resources but part of the page is organized topically and the rest by location. Consider how to store the resource data to allow displaying it either by topic or by location, and also make it searchable.
  • Look at the ​volunteer page. Compare with the existing (incomplete) volunteer module. What additional features might Maitri need to use the Eden volunteer module?

Image Library

• Provide a .represent for the view to display image thumbnail with option to zoom large (such as Fancyzoom)
• Provide a beautiful image viewer to flip between images
  • ​http://blog.lieldulev.com/2010/05/21/parallel-image-preloading-in-js/
• Use Mapping API to display images on Map
