In some examples, data representing a three dimensional object is received, the data comprising object property data indicative of at least one attribute of at least a portion of the three dimensional object. The object property data is transformed into a plurality of device independent object property data objects having a common data structure, each object property data object comprising a value indicative of each of a predetermined set of object properties. ## Claims ### Claim 1 A system to process jobs for additive manufacture of three-dimensional objects, the system comprising: a processing apparatus to receive job data specifying an object to be produced by additive manufacture and generate control data for output to a particular additive manufacturing system to produce the specified object;
