Ramesh Jain believes we need to rethink meta data if we want to escape the tyranny of digital content which will clog our hard drives. Making sense of it all is the next big business opportunity. “Text is effectively one dimensional – though it is organized on a two-dimensional surface for practical reasons.  Currently, most meta data is also inserted using textual approaches. When we try to assign tags to other media, things start getting a bit problematic due to the nature of media and the fact that current methods to assign tags are textual.” Pay attention: Jain is bringing up some serious issues here.
