Codebook Centric to Life-Cycle Centric

• In the beginning.

2
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.

3
Was the IDEA!
4

• 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

5

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

6

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

7

• 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

8

• 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

9

• 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

10
INSTANCE
Archive Information
11

• 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)

12

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

13

• 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
