A proposal of RSS WebCrawler model of product information

In this paper, we suggest a non-monopolistic distribution model of product information from publishers to subscribers by aggregators using RDF Site Summary (RSS) 1.0 with extended vocabularies. A publisher is a producer, a farmer or a food maker, etc, and submits its own product information on the Web. An aggregator is a databank, a registry or a data broker, which retrieves and stores information of products. A subscriber is a seller, a distributor or a consumer, which acquires product information corresponding to the product code such as EAN/UCC Code or RFID. The proposed model improves the quality and quantity of product information service, and also gives opportunity to enjoy new services. It gives consumers new benefits of utilizing knowledge of products, discovering unknown facts of products, etc.
