Multivendor Catalogs: Smart Catalogs and Virtual Catalogs
We discuss how distributed multivendor catalogs can be created and used by multiple retailers. Currently, there are a variety of proprietary approaches to electronic catalogs. These include WWW catalogs built with stovepipe architectures that allow only one catalog to be used at a time. Also, proprietary catalogs are created using EDI 832 transactions that limit flexibility and technological gr...
متن کاملSmart Catalogs and Virtual Catalogs
We present an architecture for electronic catalogs, called Smart Catalogs and Virtual Catalogs. Smart catalogs are searchable, annotated combinations of machine-readable (i.e., minimally processable) and machine-sensible (i.e., actually understood by the computer) product data. Virtual catalogs dynamically retrieve information from multiple smart catalogs and present this product data in a unif...
متن کاملBuilding the Infrastructure of Resource Sharing: Union Catalogs, Distributed Search, and Cross-Database Linkage
EFFECTIVE R SOURCE SHARING PRESUPPOSES an infrastructure which permits users to locate materials of interest in both print and electonic formats. TWO approaches for providing this are union catalogs and Z39.50-based distributed search systems. The advantages and limitations of each approach are considered, paying particular attention to a realistic assessment of 239.50 implementations. This art...
متن کاملVirtual Metadata Catalogs: Augmenting Metadata Catalogs with Semantic Representations
A common approach to managing large, heterogeneous, and distributed collections of data is to separate the data itself (and its physical rendering in replicas) from the metadata that describes the nature of the data (often called logical data descriptions). Metadata catalogs store descriptive information (metadata attributes) about logical data items. These catalogs can then be queried to retri...
متن کاملDiscovering Relationships Among Catalogs
When we have a large amount of information, we usually use categories with a hierarchy, in which all information is assigned. The Yahoo! Internet directory is one such example. This paper proposes a new method of integrating two catalogs with hierarchical categories. The proposed method uses not only the contents of information but also the structures of both hierarchical categories. In order t...
