FAQ

From: Alex Willmer <alex at moreati.org.uk> inquired
I'm trying to track down the name of a file format and python module,
that was featured in the Daily Python URL some time in the last month
or
two.

The format was ASCII with a multiline header defining types for the
comma seperated column data below. It may have had the capability to
store multiple tables in one file. There was news on the homepage that
an alternate 'no data here' syntax was also supported.

An example file had vaguely this structure:

columnname as datatype
columnname as datatype
columnname as datatype
columnname as datatype

data,data,data,data
data,"other data",data,data
data,data,"",data

Was it something like ARFF? http://www.cs.waikato.ac.nz/~ml/weka/arff.html

@RELATION iris

@ATTRIBUTE sepallength NUMERIC
@ATTRIBUTE sepalwidth NUMERIC
@ATTRIBUTE petallength NUMERIC
@ATTRIBUTE petalwidth NUMERIC
@ATTRIBUTE class {Iris-setosa,Iris-versicolor,Iris-virginica}


The Data of the ARFF file looks like the following:

@DATA
5.1,3.5,1.4,0.2,Iris-setosa
4.9,3.0,1.4,0.2,Iris-setosa
4.7,3.2,1.3,0.2,Iris-setosa
4.6,3.1,1.5,0.2,Iris-setosa
5.0,3.6,1.4,0.2,Iris-setosa
5.4,3.9,1.7,0.4,Iris-setosa
4.6,3.4,1.4,0.3,Iris-setosa
5.0,3.4,1.5,0.2,Iris-setosa
4.4,2.9,1.4,0.2,Iris-setosa
4.9,3.1,1.5,0.1,Iris-setosa


Lines that begin with a % are comments. The @RELATION, @ATTRIBUTE and @DATA declarations are case insensitive.
