What to do with connection capacity

[jpaulm]

In the pre-NoFlo version of .fbp notation, connection capacity was indicated by a number in brackets immediately following the arrow (->). NoFlo JSON has no provision for connection capacity AFAIK, although @bergie has suggested using metadata within the component part of a process specification.

• where do we specify capacity in .fbp notation?
• where should it be specified in the JSON output?

Did you settle on anything here?

TBH, I think the notation is well understood (capacity in brackets) and I think support in this parser doesn't undermine NoFlo.

We could 'enable' or 'disable' support in the parser with a parameter, so that we can maintain parity with NoFlo.

Looks like the only question is outputting capacity, right?

Sorry, I've been out all day, and have to head out again! Looks like connection metadata in the JSON is shaping up to be keyword-based, so I'm easy about how to encode capacity... :-)
