Forgot to ask...since you mentioned it...is there anything that you
thought should be a candidate for replacing the feature type representation?

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.

We're interested in creating pluggable serialization framework that
allows developers to choose between avro, text, and other formats of
interest (e.g. json) so that we can share the AvroSimpleFeature with
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?
