Metadata in Java Schema class

[Lars Francke <la...@gmail.com>]

Hi,

I've got a question about "metadata" in JSON schemas. According to the
specification "Attributes not defined in this document are permitted
as metadata, but must not affect the format of serialized data." What
I'd like to know is if this metadata is somehow made available in the
Schema (or Schema.Field) class. I had a look and I don't think so but
perhaps I'm missing something.

Is there any easy way to access this metadata and associate it with
the correct Schema/Fields? If not would you object against a patch
that extends the parse function to also save metadata and make it
available?

Cheers,
Lars

I had to look in the source (previously I only looked at the current
Javadoc) and yes...that does indeed seem to be what I wanted.

Thank you very much for the hint! Guess I'll just wait for the next
release then.

Is Schema.getProp() what you're looking for?
