We have recently significantly updated eLog libraries and started releasing the code through GitHub. Currently we opened the eLog UI part at (https://github.com/eLifeLogTeam/elog) for the public. The eLog server part, which now includes the updated key-value store and the event pattern mining CEP engine, is available to eLifeLog.org members. If interested, please join the community.
The eLog library was initially developed as a research prototype and later published for lifelogging researchers in 2010 to help them easily analyze heterogenous data and complex visualization. It has been kept growing with the progress of mobile computing environments and recently its UI part is released with GPL v3 license for wider usage. The eLog UI library is optimized for mobile environment and can get easily integrated with existing Web services.
