Triple-S

Triple-S, is an open standard for the transfer of survey data and its meta-data between software packages.  For information on the standard and on other packages that support Triple-S see www.triple-s.org.

 

Stat/Transfer supports Triple-S XML Version 2.  The data are contained in two files: The dictionary information is stored in a file with the extension .xml and the data are stored in a separate file with extension .asc

 

Standard extension:  xml, asc

 

Reading Triple-S

Stat/Transfer will read and use Triple-S variable and value labels. Version 2 of the standard supports both fixed format and comma-separated data files.  Stat/Transfer will read either.  Triple-S supports alternative sets of text for variable and value labels.  These are called "modes".  For example, you can have one mode for analysis and the other for interviewing.  If more than one mode is found, you will be allowed to select it by using the Table selector or the -T switch in the command processor.

 

The data file should  be in the same directory as the dictionary file (.xml) and should have the

extension .asc.

 

Writing Triple-S

Stat/Transfer writes delimited Triple-S files. 

 

Missing Values

Triple-S simply represents missing with a blank field.  Numeric fields that cannot be converted to numbers are treated as missing.  On output, missing values are written as blanks.
