Hi,
I'd like to get some feedback regarding some ideas around the
serialization format used for storage and exchange of data in monotone.
Currently, we're mostly using basic_io (for revisions, manifests, certs,
AFAIK even for automate).
Three things are bug me about basic_io:
* while well readable, it's a custom format, not used anywhere else
* it's flat and cannot represent nested structures
* it cannot handle binary data (therefore monotone is spending quite a
bit of time converting between hex and raw data (mostly revision
ids))
There are plenty of alternatives when considering a binary format: good
old ASN.1, Google Protocol Buffers, MessagePack, Blink, etc...
Human readable alternatives (which would at least eliminate the first
two concerns) might be: JSON, YAML, or (bear with me) even XML. But for
hashes and such we need a canonical format. And nothing for those three
remains readable in any of their canonical forms that I've seen so far.
At the moment, the most important question seems to be: how much do you
value the human readable representation? How about a binary format that
you can easily transform to and from a human readable one?
I appreciate your feedback.
Regards
