The datatype string is used for simple words and similar character sequences. It has the following restrictions:
- no ":=" (even inside nowiki tags it gives problems),
- not longer than 255 characters. (If you need longer strings, use Type:Text.)
If you use wiki markup inside a string property, it will not display in inline queries
You can use the special property Allows value to restrict a property to a particular set of values. For example you could limit "Status" to certain states.
The old Type:Enumeration from SMW versions prior to 1.0 is an alias for Type:String since it has the same behavior.
This type is among the standard datatypes of this wiki.
