We decided to progressively open the eLifeLog APIs. What we are working on is the documentation (http://www.elifelog.org/lab/elog_doc/). Please check it time-to-time to help us for improvement. A formal release will include the compelete set of source codes for lifelogging clients and servers. We expect that you can build your own lifelog Apps with a very short lines of codes. This documentation is the preview of undergoing works. If you are within the UNITN firewall, you can check more recent works at (http://elog.disi.unitn.it/lab/elog_doc/).
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.
