WebParts: Sharing and Reuse Component Resource in Networked Design

In this paper, a Web-based parts library management system - webParts is studied. WebParts allows engineers and designers to search for component information semantically and construct digital product design chain according to the information. WebParts is built based on PLIB standard (ISO13584) and "tabular layouts of article characteristics technology" (GB/T10091). According to the PLIB standard, a dual description method (semantic description and logical expression level) is used to express component information. The data dictionary (ISO13584-42) is used to description component information at semantic level. Because the typical structure and function feature are not described explicitly in component data dictionary (PLIB ontology), a semantic feature description dictionary (ontology) is added in the data dictionary. At logical description level, a tabular layouts of article characteristics is extracted from PLIB dictionary (especially the part characteristic) according to some rules. At last, three kinds of part search method provided by webParts are introduced
