I keep seeing people make the same mistake as XML made over and over; without learning from it. I will clarify the problem thusly:
> The more capabilities you add to a interchange format, the harder that format is to parse.
There is a reason why JSON is so popular, it supports so little, that it is legitimately easy to import. Whereas XML supports attributes, namespaces, CDATA, DTDs, QNames, xml:base, xml:lang, XInclude, etc etc. They gave it everything, including the kitchen sink.
There was a thread here the other day about using Sqlite as an interchange format to REDUCE complexity. Look, I love Sqlite, as an application specific data-store. But much like XML it has a ton of capabilities, which is good for a data-store, but awful for an interchange format with multiple producers/consumers with their own ideas.
CSV may be under-specified, but it remains popular largely due to its simplicity to produce/consume. Unfortunately, we're seeing people slowly ruin JSON by adding e.g. commands to the format, with others than using those "comments" to hold data (e.g. type information), which must be parsed. Which is a bad version of an XML Attribute.
