Re: [HTCondor-devel] idle thoughts: json as classads

[Erik Paulson <epaulson@xxxxxxxxxxx>]

C++ is a pain in the ass to use in many environments (for example, the browser)

- You'd also need to map null to something in classads.

- ClassAds would still be a superset of JSON.

- There would be natural guidance for a binary encoding of ClassAds.

- You could probably update the ClassAds language to have multiple representations - classical new ClassAds, JSON ClassAds, binary ClassAds, and XML ClassAds.  As all would use a different first character, you could have a single parser/lexer for all representations.

What's the benefit though - versus just having different converters written in C++?

If we flipped the meaning of '[]' and '{}' in ClassAds, and allowed colons as an assignment operator*, and maybe checked the different string escapes, would every JSON object automatically be a ClassAd?

It'd be kind of slick if ClassAds and JSON were a little more interoperable, and we could get some cool stuff somewhat for free. 

We could go a little farther, and work out a full syntax for ClassAds in JSON, maybe by looking at some of the JSON Referencing ideas:

This could all be first-steps towards easier interactions with HTCondor in other languages and environments.

*which I swore I thought Ye Olde ClassAds could do, but maybe it was just the config files
