        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or beaded finishes.Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications." ] ,
