Well I do not know how to do what you have comment ( re-model your data first, such that you have a timestamp or whatever. Then you could use SPARQL CONSTRUCT). But I wish it could possible because it is an integral part of my project. Regards On Sat, Sep 24, 2016 at 4:30 AM, Lorenz B. <

Thanks Soroka and Dave, but how I can do it dynamically? I used this Property property=model.getProperty(name space+ "Item price"); and then customer_1.addLiteral(property, Text Field value); Now how to remove previously entered values? Any built-in methods? On Sat, Sep 24, 2016 at 6:48 AM, A.
