A DISTRIBUTED MODEL FOR NON-STRUCTURED PRODUCT INFORMATION

Advanced manufacturing requires relevant production information model，which is divided into the structured product information （SPI） and the non-structured product information （NSPI） ．The NSPI probably exists in heterogeneous environment and is difficult to be abstracted into single database schema．This paper describes a distributed model for the NSPI catering for the enterprise’s heterogeneous environment．The model expresses the NSPI with SGML／XML，and enables access over the Web／Internet with its operation model．
