A widely used, international standard for describing data from the social, behavioral, and economic sciences. Two versions of the standard are currently maintained in parallel:
Both versions are XML-based and defined using XML Schemas. They were developed and are maintained by the DDI Alliance.
OpenPMD provides naming and attribute conventions that allow the exchange of particle and mesh based data from scientific simulations and experiments. The primary goal is to define a minimal set/kernel of meta information that enables the sharing and exchange of data to achieve
OpenPMD suits any kind of hierarchical, self-describing data format, such as, but not limited to ADIOS1 (BP3), ADIOS2 (BP4), HDF5, JSON, and XML.
The standard provides a means to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts using the W3C RDF (Resource Description Framework) standard. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations.
A set of common technical and statistical standards and guidelines to be used for the efficient exchange and sharing of statistical data and metadata.
Sponsoring institutions include BIS, ECB, EUROSTAT, IMF, OECD, UN, and the World Bank. Technical Specification 2.1 was amended in May 2012.
An extension of SDMX used to exchange statistical data and metadata.
A reference framework that provides a common terminology acroos and between statistical organisations; aligns with DDI and SDMX.
The Data Documentaion Initiative website's list of tools to implement the DDI standard.
Server-side software for building a data portal, with a particular focus on survey datasets. It uses DDI to provide access to the data at the level of concepts and variables. For an example of it in use, see the SOEPinfo data portal.
A suite of tools for managing data and metadata in SDMX.
The Linked Data Cubes Explorer allows for the analysis of statistical datasets using the RDF Cube Vocabulary.
A simple tool for managing and accessing statistical metadata, using the SDMX framework.
A tool to facilitate the mapping between the structural metadata provided by an SDMX-ML Data Structure Definition and those that reside in a database of a dissemination environment.
A list of software tools supporting the SDMX standard.

Links to DDI 3 use case papers, which were the outcomes of a workshop held at the Schloss Dagstuhl - Leibniz Center for Informatics in Wadern, Germany, November 2-6, 2009.
The statistical office of the European Union, which implementats SDMX in a number of projects.
A data archive providing leadership and training in data access, curation, and methods of analysis for the social science research community; all metadata conforms to the DDI standard.
Provides members of the scholarly community with access to files associated with scholarly studies for the purpose of replication, for all studies conducted by ISPS-affiliated researchers. ISPS metadata records conform to DDI requirements and include a minimal set of Dublin Core metadata elements.
