  2. What is Metadata ? • Metadata loosely means data about data. • A metadata record consists of a set of attributes, or elements, necessary to describe the resource in question • Metadata is a key element of census dissemination to ensure that the underlying concepts are well understood and that the results are well interpreted.

  3. Types of Metadata • Descriptive • Purpose: Resource discovery and identification • Ex.: Title, abstract, author, URL, keywords, etc. • Administrative & Rights Management • Purpose: Help manage a resource • Ex.: Who created and when, who can access, content format, rights information, etc. • Structural metadata • Purpose: Document structure • Ex.: Chapter, section, paragraph

  4. Principles and Recommendations for Population and Housing Censuses – UN : 2008 • All tabulations should include the following metadata: • Full references to where the information can be obtained • Census questions; • reasons why they are asked; • Conceptual definitions (census dictionary) • geographic hierarchies used • changes since the previous census with regard to content • operational methods or geographic boundaries; and • quality indicators such as coverage rates and item non-response.

  5. Status – Indian Census • Whereas basic metadata is provided with every table released, a complete regime is still not in place. • Few of the products based on 2001 Census data were released with complete metadata but the same practice was not followed for other products. • The Census Organisation proposes to take steps to compile metadata collection for future data releases as per the standards prescribed by the UNSD.
