Added automatic builds
Each day a ZIP-file is created via cron.
The builds consist of XMI, XSD, DocBook, PDF and graphs in dot, svg and png.
Added basic validation for names
installed module for validation, some rules for object and package names have been defined.
Added help for creating and managing the model
Guidelines for naming and propeties.
Added stage-tagging for objects
Re-arranged "Status" and added field for Stage, filter added on objects page.
Changes for Datatype
Datatype taxonomy is replaced by a datatype content type, to create a new one go to /node/add/datatype. You can specify basic documentation of the datatype and specify enumerated values. A datatype must be placed in a package.

Welcome to the development platform for the next generation of DDI

The DDI Alliance is building a new model-based specification, for more information on the background to this see, the process and what we hope to achieve see the DDI Alliance website at

A site to hold discussions and further ongoing discussion is at


Items moved from DELETED to support old material in order to save content for move from Lion


An enumeration of structure type used by a LanguageSpecificStructuredString if it is not plain text. Content of string should be entered with escape characters.


Source target relationship between classification items in a classification item relation structure


Source target relationship between codes in a code relation structure


Relation structure of codes within a codelist. Allows for the specification of complex relationships among codes.


An abstract base to allow all codifications (CodeList, StatisticalClassification, etc.) to be used as enumerated value representations.


The RegularExpressions Package contains datatypes defined as a regular expression.


Defines complex synchronous or asynchronous temporal ordering control. Defines temporal relationships using Allen's Intervals.


A subtype of WorkflowStep which controls the ordering of Workflow Steps within a Process. Abstract base for specialized ordering conditions that have specific requirements to relay ordering information.
