Codebook Centric to Life-Cycle Centric In the beginning….

We described the life cycle  But how were we going to relate this iterative life cycle in XML?  So we went back to…… In the beginning….

Was the IDEA!

 Described in the study unit Who is proposing the study Research question or purpose of the study Research population Background research Formal study proposal Funding sources Proposal Revisions Concepts and definitions

 Proposal becomes reality…Data Collection Questionnaire development Instrumentation Who collects the data How the data is collected Data cleaning Data processing  Recoding and weighting  Imputation  Suppression or allocation

 Publishing the Data: The logical product content Categories Variables nCube Including links to previously defined  Concepts  Questions  Processing activities

 Describing the Physical Data Product Link to a logical product description Multiple structures to describe different storage structures Information on relational links between record types stored in one or many data files Links to variables and NCube cells

 Record of a Physical Instance Link to a physical storage structure Specifics of the range of records in the file  Record type selection  Geographic selection  Topical selection Summary statistics Identification and location of the actual data file

 Making it visible to the outside world Publishing in-house Depositing with a distributor  Creating “archive” information  Packaging and publishing as a DDI Instance The DDI Instance now has identity as an object This means that your metadata can be “discovered”

Study Unit Data Collection Logical Product Physical Structure 1 Physical Instance (full file) Physical Instance (subset of records) Physical Structure 2 Physical Instance (full file) Archive Information INSTANCE

 Archive received instance and data Add local identification  Archive name and contact  Use restrictions or access process Record processing information  Cleaning metadata  Creating new formats / record subsets  Creating an internal physical instance (file rename for example)

 Groups Adding to an existing series Creating a new series  Time series  Topical Series  Management / Use series

 Management over time Materials added over time  Adding local concept scheme  Adding citations to publications based on data  Recording value added information discovered during use and analysis  Information change Local contact information Location information changes
