Hence, Metadata is original description of data about data or information about information, provides information about other data originated by computer communities, that is used to classify, label, understand, organised, shortening, and searching for data much easier to serve the public on assurance, automatic and discovered. Without classification, cannot manage the huge amount of data and did not make easier to find relevant data which assist in identifying the nature and features of the data. Metadata creation may be done manually or by metadata generators that’s extract key information from object. Metadata harvested captured metadata record that created and shared cataloguing model and it’s embedded in electronic resources or stored files. In this digital revolution scenario, generally utilized the cataloguing and indexing for electronic information resources. The utilization of metadata increased day-by-day, that system support metadata creation and search engine. The electronic environment challenges may boost the search engine vendor better to taken advantage of creating metadata development and made aware of the importance of it. The purpose of the study is knowing the relevant information of three tier function may cataloguing, classifying, and indexing. It facilitates to discover fact relevant information, locate the specific resources, and organise the electronic resources for new arrivals of collection or data files to provide additional information needed to administer, manage collection, allow digital objects to be re-presented in new technical environment for search category
