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 http://www.ddialliance.org/ddi-moving-forward-process.

A site to hold discussions and further ongoing discussion is at https://ddi-alliance.atlassian.net/wiki/pages/viewpage.action?pageId=491703

ClassificationItemRelation

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

CodeRelation

Source target relationship between codes in a code relation structure

CodeRelationStructure

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

EnumerationDomain

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

RegularExpressions

Package containing data types using regular expressions

TemporalRelationControlStep

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

WorkflowControlStep

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.

ClassesOnHOLD

classes from published packages that are not used in prototype TC-58

ControlledVocabularyView

Purpose:
The ControlledVocabulary view is intended to allow for the structured description of a vocabulary in DDI4. A vocabulary can be described as a simple set of terms and definitions, or a set of terms and definitions with a structure such as a hierarchy.
