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 کاملThe Phoenix Deep Survey: Optical and near infrared imaging catalogs
The Phoenix Deep Survey is a multi-wavelength galaxy survey based on deep 1.4GHz radio imaging (Hopkins et al., 2003). The primary goal of this survey is to investigate the properties of star formation in galaxies and to trace the evolution in those properties to a redshift z = 1, covering a significant fraction of the age of the Universe. By compiling a sample of star-forming galaxies based on...
متن کاملA tri-stage cluster identification model for accurate analysis of seismic catalogs
In this paper we propose a tri-stage cluster identification model that is a combination of a simple single iteration di tance algorithm and an iterative K-means algorithm. In this study of earthquake seismicity, the model considers event location, time and magnitude information from earthquake catalog data to efficiently classify events as either background or mainshock and aftershock sequences...
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...
