# Data Types#

The following data types are used throughout the Squirro platform:

## JSON#

All APIs support the input and output of JSON data.

JSON is a text format to represent simple data structures. Libraries to read and write JSON data are available for almost all programming languages. See the extensive table on http://json.org/.

## Date and Time#

Date/time values are always in UTC in the format YYYY-MM-DDThh:mm:ss (e.g. 1997-07-16T19:20:30).

## Language Code#

Language codes are always a 2-character long lower-case string (e.g. en, de, ar). For more information, see:

## Unique Identifier#

Unique identifiers are generated as 22-character long case-sensitive strings (e.g. fD9EDV2YROG7pSkBa-hLPg).

## Geographical Location#

Geographical locations include latitude followed by longitude and can be expressed as:

• Single point: string with latitude and longitude as floating point numbers (separated by comma), e.g. 47.374463,8.52375.

• Rectangle: string with latitude and longitude as floating point numbers (separated by comma) of the top-left and bottom-right corner (separated by semi-colon), e.g. 47.374463,8.52375;47.374015,8.524908.

Formatted content is represented as HTML. When dealing with such content, special characters must be escaped. Most programming languages provide utilities for this, such as Python with the cgi.escape function.
