In the ocean of information that gets transferred over the supply chain, it is difficult to get what is required for the customer. Toward this end, a description of the information is necessary. This chapter explains how metadata describes the information. In addition, it provides the framework for service description and message exchange in web services. Hierarchical representation of data abstractions to cater for the services is introduced.
Chapter Preview


The data from different sources available in heterogeneous format calls for modularity in the metadata description. The users can make use of the existing schemas rather than defining something new from the scratch.

The support for interoperability allows the data from different schemas for the seamless syntax and semantic integration. This helps in re usability of the module in different applications.

Case Study: HTML

HTML based metadata is popularly associated with the content and services associated with the web. Although it is simple, it fails to provide the description in a structured fashion.

Case Study: XML Markup

It supports the structured data although used in a small scale. Like XML, it is modular and extensible and Interoperable.
