- Description
- The new global economy is based on knowledge and information. Further- more, the Internet is facilitating new forms of revenue generation of which one recognized potential source is content delivery over the Internet. One aspect that is critical to ensuring a content-based revenue stream is billing. While there are a number of content-based billing systems commercially available, as far as can be determined these products are not based on a common model that can ensure interoperability and communication between the billing sys- tems. This dissertation addresses the need for a content-based billing model by developing the CBiX (Content-based Billing in XML Environments) model. This model, developed in a phased approach as a family of billing models, incorporates three aspects. The rst aspect is access control. The second as- pect is pricing, in the form of document, element and inherited element level pricing for content. The third aspect is XML as the platform for information exchange. The nature of the Internet facilitates information interchange, exible web business models and exible pricing. These facts, coupled with CBiX being concerned with billing for content over the Internet, leads to a number of decisions regarding the model: The CBiX model has to incorporate exible pricing. Therefore pricing is evolved through the development of the family of models from doc- ument level pricing to element level pricing to inherited element level pricing. The CBiX model has to be based on a platform for information inter- change that enables content delivery. XML provides a broad family of standards that is widely supported and creating the next generation Internet. XML is therefore selected as the environment for information exchange for CBiX. The CBiX model requires a form of access control that can provide access to content based on user properties. Credential-based Access Control is therefore selected as the method of access control for CBiX, whereby authorization is granted based on a set of user credentials. Furthermore, this dissertation reports on the development of a prototype. This serves a dual purpose: rstly, to assist the author in understanding the technologies and principles involved; secondly, to illustrate CBiX0 and therefore present a proof-of-concept of at least the base model. The CBiX model provides a base to guide and assist developers with regards to the issues involved with developing a billing system for XML- based environments.
