Datatypes in HTML

One of the challenges of using HTML as a data transport is that everything, by default, is a string. This page explores ways to use microformats -- specifically, class names -- to encode data type information, e.g., for use with xoxo and rest/ahah, in order to allow lossless import/export from various languages.

Examples

These are the primary datatypes in a range of different languages and formats. Note that we are only concerned with "primitive" datatypes (loosely defined), as structured datatypes (list/array, hash/dictionary) are handled by xoxo.

Datatype comparison table
Language/format string float integer boolean data date/time
XML Schema string float, double decimal, integer, etc. boolean hexBinary, base64Binary duration, dateTime, date, time
XML-RPC string double i4, int boolean base64 dateTime.iso8601
Mac OS X plists string real integer true, false data date
JSON (JavaScript) string number number true, false N/A Date
YAML tags str int float bool null (base 64) N/A
SQL (JDBC) char,varchar float, double, real decimal, numeric bit binary date, time, timestamp
C char* float, double int, long, short byte void* N/A
Java char, String float, double int, long, short, byte boolean N/A util.Date
