We removed "mark as key" as most users want to customize the URIs for their classes. The "workaround" for this is to define a PyTransform on the column you want to use as the "key", and then you have the opportunity to customize it. Then map the new column as the "uri of class"
Apologies if this caused you inconveniences. When we upgraded the code to be more compliant with R2RML we removed this feature, which is not directly supported in R2RML.
It used to be there, and it's in the doc., but I can't see it anymore ( with the master HEAD code ).
