ICPSR-SRO Shared Data Model Project Mary VardiganDirector, DDI Alliance
Both are units of the Institute for Social Research, University of Michigan Inter-university Consortium for Political and Social Research (ICPSR) ICPSR is a large social science data archive Survey Research Operations (SRO) SRO is a data collection center The Partners
Worked together on the National Survey of Family Growth, sponsored by NCHS, to create an interactive codebook Partnered again on the Collaborative Psychiatric Epidemiology Surveys, sponsored by NIMH This involved a harmonization of three datasets and interactive documentation featuring question comparison and five languages Past Collaborations
Together, SRO and ICPSR cover the life cycle of research data We share a need for rich, high-quality metadata We want to comply with metadata standards – in particular, the Data Documentation Initiative (DDI) We need to pass data easily from SRO to ICPSR without information loss Rationale for Collaboration
Shared data model and database design for survey metadata to enhance collaboration Challenges: Different computing platforms Different end products Different staff orientations New SRO-ICPSR Joint Project

SRO Tools to complement MQDS, which produces XML documentation from Blaise instruments Tool to permit external users to add metadata for the National Survey of Family Growth ICPSR Variable-level database that permits users to search across the ICPSR collection; compare variables; create new datasets and questionnaires Products and Benefits
Should allow nearly seamless data sharing between SRO and ICPSR Covers survey data life cycle from data production to data publication Creates a competitive set of services that we can continue to market Ultimately brings more data to a wider audience Other Benefits of the Project
Phase 1 Design and development of the database (April 30, 2008) Modification of MQDS to export to and read from the database (April 30, 2008) Interface to allow remote user access for NSFG (July 31, 2008) ICPSR Social Science Variables Database (Late 2008) Project Phases
