I like the WKT name...I do remember now seeing that in your tutorial
(thanks for those by the way).
By feature type representation do you mean the
"name1:Integer,name2:Float" syntax? One thing that we run into with some
of the cloud toolkits is that they don't allow spaces or dashes for
field names (only alphanum + underscore, avro being a prime example). A
side effect of pluggable serialization may be that we restrict feature
names to alphanum+underscore whereas now we can do spaces, etc. I assume
something like that would have be difficult to make backwards compatible
but could be mitigated with some sort of naming restriction API.
I'll send a proposal once I do some more research.

others and register serializers via SPI similar to DataSources.
On another note, what is the standard pipe-delimited format known as?
Pipe Delimited Text?
I made it up for PropertyDataStore tutorial, since it uses
Well-Known-Text to represent geometry you could call it WKT?
The feature type representation is cribbed from an old 4th gen
language called cause and effect I used to work with. But really it
was just to get around the single line restriction of Java property files.
If anyone has any ideas/comments/interest let me know!
Your idea for pluggable serialization sounds fun, perhaps make a
proposal when you are ready?
