Google DataWiki is a wiki for structured data, extending the idea of a normal wiki to make it easy to create, edit, share and visualize structured data, and to interlink data formats to make them more understandable and useful.
Othere features includes:
- create simple mashup applications in a few minutes
- define formats in terms of others, e.g. Missing Person reports = vCard (who) + GeoRSS (last seen) + string (current status note)
- share information with other systems via built-in federation
- enable easy input/output from a variety of endpoints, e.g. via Twitter, ODK or SMS from a remote location
The project is inspired by the need to create customized data formats for crisis response, for example to quickly create a person-finder application after an earthquake, or share Internet and cellular phone connectivity maps from an affected area.
DataWiki operates as a RESTful web-service, is built on AppEngine and is completely open source.
