CFP: DDI Workshop: Managing Metadata for Longitudinal Data – Best Practices

DDI Workshop: Managing Metadata for Longitudinal Data – Best Practices
September, 19-23, 2011
Leibniz Center for Informatics, Schloss Dagstuhl, Wadern, Germany
This symposium-style workshop will bring together representatives from major longitudinal data collection efforts to share expertise and to explore the use of the DDI metadata standard as a means of managing and structuring longitudinal study documentation. Participants will work collaboratively to create best practices for documenting longitudinal data in its various forms, including panel data and repeated cross-sections.
Description of the workshop
Longitudinal survey data carry special challenges related to documenting and managing data over time, over geography, and across multiple languages. This complexity is often a barrier to building efficient systems for data access and analysis. DDI (Data Documentation Initiative) Lifecyle, a metadata standard that addresses the full life cycle of social science research data (formerly referred to as DDI 3), is designed to provide an efficient structure for the documentation of complex longitudinal data. In this workshop, participants involved in longitudinal data projects around the world will work together on issues involved in documenting longitudinal data.
Intended audience: Individuals with expertise in longitudinal social science data; knowledge of DDI is desired but not required. The intent is to have a mix of participants with substantive and technical skills. Participants should provide access to materials describing their projects, which can serve as use cases in applying DDI. The workshop is in English. This is the second Dagstuhl workshop on the topic; the first took place in October 2010. The upcoming workshop will continue the in-depth discussion begun last year, expanding into additional topics.
Expected Results
Participants will write best practice papers, to be published in the DDI Working Paper Working Paper Series. Last year’s workshop produced a series of best practice papers on longitudinal data.
Possible Topics
Documenting comparison, harmonization, and the relationship among concepts, questions, and variables over time, as well as the relationship of respondent types (person, household) are typical issues for longitudinal data. Other topics not specific to longitudinal data:
– Classifications (e.g., ISCO, ISCED)
– Data collection details
– Qualitative data, other types of data sources beyond surveys
– Quality of metadata and data
– Data management planning
– Relationship to the Open Archival Information System (OAIS)
– Extension of DDI for specific needs
These topics are often more salient for longitudinal data, making it even more critical manage these metadata in a structured form over time and countries. The current possibilities of DDI Lifecyle will be explored and areas for future extensions identified. Additionally, participants can suggest their area of interest.
The workshop will take place at the Leibniz Center for Informatics, Schloss Dagstuhl, Wadern, Germany. The non-profit center is a member of the Leibniz Association and is funded jointly by the German federal government and a number of state  governments. The venue provides an intense working atmosphere in a nice remote region. Several seminar rooms and cafeteria while the day, and leisure rooms like wine bar and billiard room while the evening promote intense discussion and communication. Accommodation costs at Dagstuhl including full board is 60 Euro/day/person (subsidized rate).
This workshop is sponsored by the DDI Alliance, GESIS – Leibniz Institute for the Social Sciences, Minnesota Population Center (MPC), and Open Data Foundation (ODaF).
The names of interested organizations and individuals should be sent to Please provide contact information, area of interest, and area of expertise for each individual, information regarding DDI Lifecyle implementation, and a statement of what each individual can contribute to the workshop. Direct questions to Twenty-one participants will be accepted.
