> http://erlang.org/pipermail/erlang-questions/2014-March/078228.html Loic says that JSON is "a terrible format" because: It's text-based, meaning it's incredibly slow to parse. Shall I conclude, then, that all text-based formats are bad? XML is a text-based format. Parsing is one of the most mature Computer Science subjects. Although I don't have performance metrics, I am skeptical that text-based formats are "incredibly slow to parse." It has to be valid UTF-8, meaning it's incredibly slow to validate. XML is by default UTF-8. Its numbers representation is double-precision floating-point, meaning it's incredibly imprecise and limited. Here's what the JSON specification says about numbers: JSON is agnostic about numbers. In any programming language, there can be a variety of number types of various capacities and complements, fixed or floating, binary or decimal. That can make interchange between different programming languages difficult. JSON instead offers only the representation of numbers that humans use: a sequence of digits. All programming languages know how to make sense of digit sequences even if they disagree on internal representations. That is enough to allow interchange. /Roger -----Original Message----- From: Simon St.Laurent [mailto:simonstl@s...] Sent: Monday, June 09, 2014 9:18 AM To: xml-dev@l...

The piece of that I keep finding in these kinds of conversations is: "I do not have a magical format to propose to replace it (I tend to go with msgpack, but it also has its issues, though not as many as JSON) but perhaps I should work on it soon in preparation for my EUC talk." Messaging formats are hard. I'll be curious what Loic's come up with at this point. Despite the Erlang community's fondness for ASN.1, I'm guessing it's not that.
