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.


This datatype is modeled after the calendar dates defined in Chapter 5.2.1 of ISO (International Organization for Standardization) 8601. Its value space is the set of Gregorian calendar dates as defined by this standard; i.e., a one-day-long period of time. Its lexical space is the ISO 8601 extended format: [-]CCYY-MM-DD[Z|(+|-)hh:mm]

Valid values include: 2001-10-26, 2001-10-26+02:00, 2001-10-26Z, 2001-10-26+00:00, -2001-10-26, or -20000-04-01.


The datatype xs:boolean has the ·value space· required to support the mathematical concept of binary-valued logic: {true, false}. (

An instance of a datatype that is defined as boolean can have the following legal literals {true, false, 1, 0}


HOLDING OBJECT ONLY - Represents the Primary reference for the conduct of the study


The possible list of values that are allowed by a Capture.


Implementation of the LogicalInstrument


Design plan for creating a data capture tool.


InstrumentComponent is an abstract object which extends an Act (a type of Process Step). The purpose of InstrumentComponent is to provide a common parent for Capture (e.g., Question, Measure), Statement, and Instructions.


A Statement is human readable text or referred material.


Instructions used by the interviewer or respondent to support the accurate collection or capture of data


An instance question is an instantiation of a represented question,to be used as an Act in the process steps that define a survey questionnaire.
