BEY and BESY

Thanks Steve,  I appreciate the dialog  ...  in the embedded forums I usually lurk YAML and human readable is a foreign concept.  

Here's where the mini design stands:

Binary Encodable Schema in YAML (BESY)
Binary Encoded YAML (BEY)
 - BESY is valid a YAML document
 - (YAML data + BESY schema for the data) enables conversion to/from BEY
 - (BEY data + BESY schema for the data) enables conversion to/from YAML
 - YAML data created with BESY may be subject to additional type checking and constraints
 - BEY encoding could be same as protobuf (exact encoding TDB or could be multiple)

One of my main goals is to allow a YAML-like syntax to be used in designing protocols for lower layer protocols and constrainedd devices.  I suspect the TLV crowd will have a similar response to YAML as this forum has to binary encoding :-)   

If/when the design reaches the next level I'll post a pointer to this list ...
