For the interactve support and knowledge archiving, now our eLifeLog API documents support user comments using DISQUS (See our works to enable this at http://www.elifelog.org/book/elifelog-api-documentation-user-comment-support-using-disqus). So your comments are very welcome! :)
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.
