Strategic Priorities for DDI Spring 2013 Mary Vardigan Director, DDI Alliance METIS -- Geneva, Switzerland May 6, 2013

Today’s Presentation About DDI and its benefits Priorities for the future Working together on new goals

What is DDI? A metadata specification of and for the community Two major development lines –DDI Codebook –DDI Lifecycle Metadata for both human and machine consumption Additional specifications: –Controlled vocabularies –RDF vocabularies for use with Linked Data

Lifecycle Orientation

Benefits of the DDI Approach Rich content (currently over 800 items) Metadata reuse across the life cycle Machine-actionability Data management and curation Support for longitudinal data and comparison

Global Reach

Strategic Priorities Data “ecosystem“ undergoing rapid change – how can DDI respond? 1. Restructuring for new success 2. Developing the next-generation DDI 3. Outreach to the community

Priority 1 -- Restructuring Aligning DDI governance structure to meet the needs of a mature organization Revised Charter and Bylaws with appropriate representation of the membership Secretariat housed at University of Michigan

Priority 2 – Creating next-generation DDI Will be model-based –Easier to understand –Better interaction with other disciplines and standards –Easier to develop and maintain in a consistent way –Will enable more efficient software development Roadmap developed to guide model creation

Model Design Goals 1.Interoperability, Standards 2.Simplicity 3.User Driven 4.Terminology 5.Iterative 6.Documentation 7.Lifecycle Orientation 8.Reuse and Exchange 9.Modularity 10.Stability 11.Extensibility 12.Tool Independence 13.Innovation 14.Actionable Metadata

New Content Abstraction of data capture/collection/source to handle different types of data New content on sampling, survey implementation, weighting, and paradata New content related to qualitative data Framework for data and metadata quality Framework for access to data and metadata

New Content II Process description across life cycle, including support for automation and replication Integration with GSBPM/GSIM, SDMX, CDISC, Triple-S Disclosure review and remediation Data management planning Standard queries and/or interface specifications to enable interoperable services

Related Priorities Continue developing RDF vocabularies, to be published by the end of the year Pursue ISO certification for DDI, following success of SDMX Continue to provide training

Priority 3 -- Outreach to the Community Work with NSIs Several NSIs are DDI members SDMX-DDI dialogue Support for GSIM development

GSIM-SDMX-DDI Mapping GSIMDDISDMX

GSIM Work Developing implementation layer for GSIM Many correspondences between GSIM and DDI Mapping revealing relationships among DDI, SDMX, and GSIM and will expose gaps Hope to capitalize on the commonalities and also build out areas of DDI not currently covered

GSIM Model

Conclusion Three priorities take DDI into the future for success Looking forward to working with NSIs around GSIM Alliance would like to contribute to future collaborations
