caDSR Database Implementation of ISO 11179

Introduction

This document contains information about the caDSR implementation of the ISO 11179 edition 2 standard.

Extensions

Over time user requirements have resulted in extensions to the caDSR beyond the base ISO 11179 standard. These extensions are optional. Meaning a pure ISO 11179 object can be hosted in the caDSR without errors in the database or tools. The specific conditions of the extensions are given in detail. Beyond the documented conditions the extensions are in an unknown state and most often have a NULL value, however it should not be assumed the presence of a NULL is indicative of the object state. For example the Value Domain High Value may be NULL because the Value Domain is Enumerated or the Datatype is not numeric. It may also be NULL because the largest valid value is infinity, i.e. unbounded.

Administered Item Subtypes

The following have been created as subtypes of Administered Item.

• Form Elements
• Forms
• Question
• Value Meanings
• Concept Class
• Classification Scheme Items

Concept Derivation Rule

• Concept=Concept Relationship to include more attributes to specify a particular rule for combining concepts

Concept Class

• Associations extended to include Property, Value Meaning, Representation Term, Value Domain reference

Object Class Relationship

• Additional attributes

Value Domains

caDSR Model Package and Class: gov.nih.nci.cadsr.domain.ValueDomain

High Value

caDSR Model Class Attribute: highValueNumber
datatype: String

Controlling ISO attributes "datatype", "non-enumerated".

For non-enumerated Value Domains when the datatype is numeric this bounds the largest valid value, inclusive.

NULL indicates an unbounded value.

Low Value

caDSR Model Class Attribute: lowValueNumber
datatype: String

Controlling ISO attributes "datatype", "non-enumerated".

For non-enumerated Value Domains when the datatype is numeric this bounds the smallest valid value, inclusive.

NULL indicates an unbounded value.
