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


Set of specific units (people, entities, objects, events), usually in a given time and geography.


A tightly bound pair of items from a controlled vocabulary. The extent property describes the extent to which the parent term applies for the specific case.


Generic (untyped) ordered relationship between collections.


Parent-child specialization of OrderRelation between Levels.
The inherited type property is set to "total" to specify that the parent-child relationships among Levels in any given NodeSet define a linear sequence.

Build Test



Type of collection in terms of uniqueness semantics.
Controlled vocabulary: {bag, set}.


The Discovery View provides basic information on Annotation, Coverage, and Access. The current view is limited to this basic set of objects and is provided to test out these structures. The Discovery View will modify as more content is available. The future intent is to make this view closer to DISCO as development continues.
