The following works with the current beta, you can find another example in
core-dat.mkiv.
\definedataset[test-1]
\definedataset[test-2]
\starttext
\setdataset[test-1][x=Value X 1,y=Value Y 1]
\setdataset[test-1][x=Value X 2,y=Value Y 2]
\setdataset[test-2][a][name=Ben Lee User,job=Manager]
\setdataset[test-2][b][title=TeX by Topic]
\startlines
\datasetvariable{test-1}{1}{x}:\datasetvariable{test-1}{1}{y}
\datasetvariable{test-1}{2}{x}:\datasetvariable{test-1}{2}{y}
\stoplines
Name: \datasetvariable{test-2}{a}{name} \par
Job: \datasetvariable{test-2}{a}{job} \par
\stoptext
