3 IHSN Activities Coordinating survey programs Web based information on planned surveys Harmonizing concepts & methods Planning, sampling, questionnaire design, processing, data disclosure & confidentiality, etc. Maintaining a survey catalog Web based central catalog Developing data dissemination tools Microdata Management Toolkit

4 IHSN Website

5 Microdata Management Toolkit Tools to facilitate archive and dissemination of surveys

6 Toolkit Requirements User friendly software for microdata Facilitate metadata exchange (DDI, Dublin Core) Facilitate archiving (metadata and data, quality control) Facilitate preservation/dissemination: network, CD / DVD, web sites Works with common data formats Multilingual support Free or Inexpensive Availability of technical support and training Supported by national, international and research communities

7 DESCRIPTIVE INFORMATION RESOURCE DESCRIPTION FRAMEWORK W3C CONSORTIUM RSS NEWS XML TAGS MARKUP DOCUMENT What is metadata? eXtensible Markup Language XML, XSL, DTD, XSD, SOAP, XQUERY,… METADATA EXCHANGE SEMANTIC WEB WEB 2.0 STANDARD SPECIFICATIONS EASY TO TRANSFORM HUMAN READABLE SEARCHABLE MACHINE PROCESSABLE WEB SERVICES ONTOLOGIES

8 What is metadata? DATA ABOUT DATA

9 What is metadata? Unlabeled stuffLabeled stuff The bean example is taken from: A Managers Introduction to Adobe eXtensible Metadata Platform, Source: Courtesy of Jostein Ryssevik, Nesstar Inc.

11 International Standards Data Documentation Initiative (DDI) Surveys (description, files, variables) Microdata Management Toolkit, DevInfo Statistical Data and Metadata Exchange (SDMX) Time series, indicators DevInfo5 Dublin Core (DC) Documents, images, maps, other resources Microdata Management Toolkit, DevInfo5, CDS/WinISIS ISO Geographical Information Systems (GIS) DevInfo5 ISO Registries, classifications, life cycle future catalog tools Important to adopt and to promote use

12 Generate HTML based CD-ROM Import metadata and prepare CD-ROM Import data and compile metadata The Toolkit Process 1 2 3

13 Toolkit Components Archiving: Metadata Editor (World Bank / Nesstar Ltd.) Compile survey data, documentation and metadata in a standard format (Nesstar/DDI). Free data reader for users. Built on Nesstar Publisher Dissemination: CD Builder (World Bank / Mark Diggory) Facilitate the publication of survey data, documentation and metadata on CD-ROM and on the web (transforms DDI into HTML based navigation) Based on Eclipse Platform, open source Nesstar Explorer Free software Access metadata & data and export to common statistical formats IHSN Tools Reporting, diagnostics and other utilities

14 What is the Metadata Editor? DDI / Dublin Core specialized editor Template driven Import/Export common data files Integrated interface, multilingual support Metadata and data in single file Export to DDI / DC Licensing agreement for developing countries and IHSN members

15 What is the Metadata Editor?

16 What is the CD Builder? Publish survey metadata, documents and data on a CD-Rom or web site) Transforms DDI into an HTML based interface User can customize the layout (branding) and content of the CD (single or multi-surveys) Based on DDI / Dublin Core Integrates with Metadata Editor

17 CD Builder Process Create new CD-ROM Project Add a survey to the project and select its type and branding 1 2 Selecting a survey consist in opening the DDI-XML or Nesstar file The survey branding determines the overall look and feel of the CD The survey type determines the default metadata content Selecting a survey consist in opening the DDI-XML or Nesstar file The survey branding determines the overall look and feel of the CD The survey type determines the default metadata content Click the Save button to generate the HTML interface 3 After a few minutes, your CD Project is ready for publishing! 4

18 Sample output

19 Nesstar Explorer Free software PDF philosophy Access to survey metadata Access to data (no need for specialized software) Export to common formats Single file holds data and metadata

20 IHSN Tools Free / Open Source Utilities to complement existing software Integrates in Editor Diagnostics Reporting Metadata sharing

21 Benefits and Users Improves and facilitates documentation preservation, cataloguing, metadata exchange, dissemination, quality, etc. Users: survey producers, survey sponsors, data archives Benefits: data producers, national & international survey sponsors, survey data repositories, data analysts, policy makers, DDI Community
