  3. Census Bureau Metadata Objectives • Gain Acceptance of One Logical Metadata Registry Model • Support wide Range of Projects, Surveys, Applications, and Users • Comply with Federal Standards Open Forum on Metadata Registries

  4. Statistical Metadata: Definition Definitions • Descriptive information or documentation that facilitates sharing and understanding statistical data over the lifetime of the data. • Includes • file location, record layout, database schemas, data dictionary, definitions, questions, questionnaires, sample design, processing steps, data quality, etc. Open Forum on Metadata Registries

  5. Purposes of a Statistical Metadata Repository • End-user oriented • Electronic Data Dissemination • Production oriented • Automated Survey Design and Processing Open Forum on Metadata Registries

  6. What is the Corporate Metadata Repository (CMR)? • Electronic card catalog • Provides access to metadata describing many classes of objects • throughout a survey • across many surveys • Types of classes are • variables or data elements questionnaires • datasets other products (reports) • documents surveys • Metadata quality monitored through registration process Open Forum on Metadata Registries

  16. Long Term Implementation:Integrated Information Solutions Program (IIS) • Data Integration, Access and Delivery • provides access to integrated data sets • provides ongoing customer support • Product Creation System • Policies and Standards • New Business Practices • Metadata and Data Support Open Forum on Metadata Registries

  17. Current Situation Observations • Each Program Area Operates Independently, Thereby: • Creating difficulty when two program areas must coordinate • Discouraging the notion of corporate data or metadata assets • Minimizing economies of scale or reuse • Discouraging the production of and access to integrated data Open Forum on Metadata Registries
