Sure, when I get a chance, I'll build up some mock YAML stuff. Most
YAML is correct JSON, so I'm not concerned about the JSON case right

mmmm. Bacon. Mayhaps we call it the Bacon Testing Protocol? Delicious.

And INI files have some annoying as hell restrictions, YAML support
conversion from items within the file to native data types, such as
lists, ints, and so on. I don't want to have to parse it and do the
conversion myself. Many people have written custom parsers to do this
conversion for you, such as Michael (configobj) but again, why not use
something which support conversion to native data types so that the
job is easier on the parser and emitter?

Personally, anything I do will be under a BSDish license. Business reasons.

No, we're talking about a file with some custom fields. That's worlds
different than a DSL. And true, the syntax doesn't "say what it means"
- but it does provide the type of the object, which goes a long way.

That's what my goal is/was: define the fields in the file. It just so
happens my example is somewhat valid YAML.

job_id: UUID
recv_time: FLOAT
build_id: STR
machine_id: STR (uuid?)
execution_line: STR

   total_tests: INT
   total_pass: INT
   total_fail: INT
   total_other: INT
   start_time: FLOAT
   stop_time: FLOAT
   total_time: FLOAT

       id: STR
       result: STR
       result_id: STR
       start: FLOAT (time.time())
       stop: FLOAT (time.time())
       total_time: FLOAT (seconds)
           coverage_info: Big str
           stdout: Big Str
           stderr: Big str

   requestor_id: INT
   artifacts_uri: <your path here>
   artifacts_chksum: MD5
   configuration_file: (the config file passed in in my case)

Roughly parsed into { job_id : value, test_cases : { ... } } and so
on. See http://pyyaml.org/wiki/PyYAML. The values on the other side of
:  characters are converted to native data types and things like
lists, etc.
