Data Capture Development
(DDI Technical Committee)
|
Example of use of data capture development content to describe the development of a question and the use of a question in a questionnaire. Includes Development Plan, Development Implementation, Development Activity, and Development Results. |

Data Capture Development
(DDI Technical Committee)
|
This example shows the use of the Data Capture Development objects including the documentation of development activities such as translation and review activities. In addition to tracking these specific activities the example illustrates the means of linking a question or measure to the development activities which resulted in the final form of the question/measure used. |

Date Expressions
(DDI Technical Committee)
|
Example of the different types of date expressions including a single date, full date range, range with an unknown start date, and range with and unknown end date. |

DDI Lifecycle use of SDTL content
(DDI Technical Committee)
|
This example shows the use of SDTL content by DDI Lifecycle to describe a generation instruction and provide command code to process the instruction. |

Input Parameters, Output Parameters, and Binding support passing data through a process.
(DDI Technical Committee)
|
This is a very detailed example walking through all the control constructs, questions, dynamic text, and control constructs. In general usage bindings out parameters and bindings would be noted at the highest discrete level such as the Question Construct for the data captured by a Question Item. Identification and binding at this level keeps the question reusable across various uses in a questionnaire. |

Note Example
(DDI Technical Committee)
|
Note is designed to be an inherent part of the DDI passing along with a DDI object over its lifetime. It is not intended to replace formal extension mechanisms. Formal extension should be used whenever a locally used object needs to be added to the schema. However, run-time extension needs may arise and Note can be used to capture the required metadata and associate it with the appropriate object. This example shows a production process note, a work-around, and a proprietary content note. |

Representation Types
(DDI Technical Committee)
|
Examples of various Representations in the form of Managed Representations, new geographic code representations with restrictions, and the use of Representations used expressly as Response Domains (geographic, distribution, ranking, location, and nominal). |

Represented Variable Example
(DDI Technical Committee)
|
Represented Variable and use by a Variable with restrictions on the Universe in two different ways; restricting the geographic coverage, and restricting the age of persons covered by the variable. |

Sampling Example
(DDI Technical Committee)
|
Example of the use of sampling content to describe the sampling plan, sample frame used, implementation of the sampling plan, and resulting sample details. |

Summary Statistics
(DDI Technical Committee)
|
Example of Statistical Summary found in Physical Instance. The example includes summary statistics (variable level) weighted and unweighted as well as filtered and unfiltered variable and category statistics. |
File |
Weighting Example
(DDI Technical Committee)
|
An example of weighting information including methodology, description of a weighting process, usage guide, and the ability of a variable to use this information to reference a weighting process. |
