Hi Thomas Beale, At first, I am much sorry about lacking links. http://www.rugson.org/pdf/PSRCPattaya2012.pdf In this presentation, serialisation formats were compared with features and metrics, such as size and (de)serialise performance.
And the second, to address binary data in ODIN format, I think using typing system might be good. ex. my_binary_data = (Binary:Base128)<211234blurblur> 2013/4/26 Thomas Beale <thomas.beale at oceaninformatics.com>: > > Shinji-san, > > thanks for the feedback. > > > On 25/04/2013 15:39, Shinji KOBAYASHI wrote: > > Hi Thomas Beale, > > My comments: > 1) Page 33, A2 > JSON is no Java Simple Object Notation.
