Based on the analy sis of manuf acturing infor matio n, a unif ied manuf actur ing info rmation model is built to describe r espectively the informat ion o f materials, pr ocesses, parts and reso ur ces . W ith the suppo rt of this mo del , a structured ex pr ession of manuf acturing info rmation is presented . Diff erent kinds o f in- fo rmation mapping processes are ana lyzed, and tw o g roup s o f ar ithmetic operator s the nodes/ attr ibutes a rith- metic units and the condition ar ithmetic units are def ined . A n example is u sed t o ex plain how t he operato rs w o rk dur ing the pro cess o f informat ion mapping. A messag e- or iented middlew ar e based integ ratio n fr amew o rk is pr oposed, and
