Issue No. 12 - December (2007 vol. 19)
The whole product lifecycle consists of three phases: Beginning Of Life (BOL), Middle Of Life (MOL), and End Of Life (EOL). Although large amounts of product lifecycle data are generated over the whole product lifecycle, data flows are rather vague after BOL. Over the last decade, however, emerging Internet, wireless mobile telecommunications, and product identification technologies have created the potential to make the whole product lifecycle visible. As a result, the scope of data to be managed has expanded over the whole product lifecycle. Hence, it becomes important to describe product lifecycle meta data in a systematic manner. Although much attention has been paid to data modeling over several objects such as products and processes, modeling methodology for product lifecycle meta data is not well developed. To cope with this limitation, we develop a modeling method for product lifecycle meta data using the resource description framework (RDF). We define an RDF data model and its schema for describing and managing product lifecycle meta data. In addition, we describe how the proposed RDF model can be usefully applied to track, trace, and infer product lifecycle data with an RDF query language.
