Documentation Initiative (DDI)¶
The Data Documentation Initiative (DDI) is an international project to create a standard for information describing statistical and social science data. Begun in 1995, the effort brings together data professionals from around the world to develop the standard. The DDI specification, written in XML, provides a format for content, exchange, and preservation of information. Version 3 of the DDI standard was released in April 2008.

Colectica and DDI¶
Most of the information stored in Colectica is stored natively in DDI format. The support for open standards ensures that your data is never locked in a black box. You can always extract your information and use it with other tools, too.
Several of the Colectica developers serve as invited experts on the DDI Technical Implementation Committee, where they help solve issues and add functionality to the DDI standard.
Colectica Repository is designed based on principles from the ISO/IEC 11179 standard.
ISO/IEC 11179 (formally known as the ISO/IEC 11179 Metadata Registry (MDR) standard) is an international standard for representing metadata for an organization in a Metadata Registry.
Today, organizations often want to exchange data quickly and precisely between computer systems using enterprise application integration technologies. Completed transactions are also often transferred to separate data warehouse and business rules systems with structures designed to support data for analysis. The industry de facto standard model for data integration platforms is the Common Warehouse Model (CWM). Data integration is often also solved as a data, rather than a metadata, problem, with the use of so called master data. ISO/IEC 11179 claims that it is a standard for metadata-driven exchange of data in an heterogeneous environment, based on exact definitions of data.
