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 Concepts, both sentinel and substantive, that can be described by either enumeration or by an expression.



A means of performing the qualitative coding workflow step as part of a concrete implementation of a Business Function (an ability that an organization possesses, typically expressed in general and high level terms and requiring a combination of organization, people, processes and technology to achieve).


Sequencing of coding that can be defined either by Temporal or Order Relations as wel as conditional control constructs.


A Workflow is an realized Process which identifies the WorkflowSequence which contains the WorkflowSteps and their order. Describes the design, preconditions, results, algorithm, and workflow sequence of a workflow. This is an abstract class which is instantiated for specific processes.


The method by which coding is performed.


A process step within the overall coding process.


Describes how the design of the coding is used to meet the goal of the coding.


How, in general, coding will be performed.The design informs a specific or implemented process as to its general parameters.
