Review of metadata formats

Increasing use of the Internet has heightened awareness among the information community of the need to provide user friendly searching and navigation tools that lead to quality information. An essential part of gaining effective access to Internet resources is to provide an index of available items in order to save users time and network overload. Discussions on metadata are focused on the format of the record used as the basis for the index. Control of the vast number of resources of the Internet requires an appropriate record format (or formats) which will enable the resource to be adequately described and easily located; records must be compatible with an appropriate search engine which in turn would ideally be compatible with a search and retrieval Internet protocol and all components should conform to international standards. At present there are a number of formats which meet at least some of these criteria, each of which has its own strengths.
