• WebDAIS will act as a registry
– Concept management• Enables harmonization of data
• Future– Build model for DDI– Harmonize with ISO/IEC 11179

• Object Class (i.e., Population)– A set of objects on which observations are taken
• Property (i.e., Characteristic)– A feature that describes or distinguishes objects
• Data Element Concept– The concept formed by Object Class + Property

• Bookmark List– Client Side – List of useful URLs
• Browse List– Server Side – Classify Objects by Server
• Variable Groups– Link Group of Variables, Based on Business Requirement

WebDAIS Model
• Administration Model (ISO/IEC 11179)– Data Archive
• Data Library Metadata Registry– ISO/IEC 11179 Metadata Registry – Really a Data
Element + Value Domain + Concept Registry
– Example – Car Registry
• Card Catalog Administered Items
• Catalog Items Model Attributes

WebDAIS Model
• Administration Model (ISO/IEC 11179)– What Do You Want to Keep Track of?
• Descriptions of Objects
– What Kind of Objects?• DDI?? Data sets
• ISO/IEC 11179 Data Elements + Value Domains
– Administered Item Description of an Object

WebDAIS Model
• Administration Model (ISO/IEC 11179)– Registration -
• Registration is the process whereby unambiguous identifiers are formally associated with objects.
– Administration -• Manages life-cycle of descriptions
– Administration records
• Monitors quality of metadata– Registration status
– Applies to scope of registry, not just core model

Differences among DDI, DAIS, and ISO/IEC 11179
• DDI– Subject matter specific– End user perspective - “Metadata after the data”– XML DTD - not UML model– Data set oriented– Document oriented - codebook– “Study” is highest level of abstraction
![Page 24: Is Your Data Facility ISO Compliant? Progress Towards Harmonizing the DDI and ISO/IEC 11179](https://reader036.vdocuments.us/reader036/viewer/2022062422/56813507550346895d9c5513/html5/thumbnails/24.jpg)

Differences among DDI, DAIS, and ISO/IEC 11179
• ISO/IEC 11179– Independent of particular subject matter– Producer perspective - “Metadata before the data”– UML model– Data and database oriented– “Concept” is highest level of abstraction– “Administration” is highest level of function

Differences among DDI, DAIS, and ISO/IEC 11179
• DAIS– Concept of variable group
• Not a DEC
• May be added to ISO/IEC 11179
