  1. Metadata at Statistics Austria METIS-Workshop Lisbon, April 2008 Thomas Burg, Günther Zettl Statistics Austria www.statistik.at

  2. Outline History of metadata at Statistics Austria Motivation and boundary conditions The database of concepts and definitions in the context of IMS (Integrated Metadata System) Lessons learned - Outlook

  3. History of metadata at Statistics Austria (I) ~ 1972 – Development of ISIS ~ 1985 – DOK – technical metadata ~ 1993 – 1st kind of classification - Database ~ 1996/97 – BASIS2000+ – theoretical considerations about metadata ~ 2001 – STAT+ - business process models (4- layer) ~ 2000 – up to now - implementation of single projects

  4. Projects involving Metadata – currently running Publication Database eQuest Standard Documentations ISISnew Superstar Classification Database Integration is missing!

  5. Motivation for a systematic approach Boundary Conditions (I) In the year 2000 the legal status of official statistics in Austria changed The Statistical Council acting as controlling instance for statistical production processes. In this context the availability of metadata was a key demand A quality subgroup of the Statistical Council has the desireto learn more about our products. => external motivator

  6. Motivation for a systematic approach Boundary Conditions (II) The conditions for production statistics became more difficult More work but less resources To run Metadata-systems means a work load for subject matter statisticians The willingness of the top management to invest a lot of moneyis not high General situation shows the need for doing something => internal boundary conditions

  7. Motivation for a systematic approach Boundary Conditions (III) - Summary Concept of an Integrated Metadata System Start with onepart of theIMS DECISION Database ofConceptsand Definitions Internal situation External pressure

  8. IMS Architecture

  9. Registry Registration of „information objects“ • Statistics-Austria-wide unique ID Specification of relations between „information objects“ • Different types of relations Meta-Metadata • Subsystems and legacy systems, types of information objects, types of relations, etc. Functions needed for several subsystems • Access rights, „Owner“, attachment of documents and hyperlinks, etc.

  10. Presentation of the IMS concept External view: integration of metadata in homepage → set of linked HTML pages Internal view: metadata management tool → prototype (based on Eclipse)

  11. Lessons learned Communication problems Lack of resources - human - financial Resistance Outlook: 2 possible scenarios: 1. The costs are bearable: development, statistical project database as next step,….., IMS 2. The costs are unbearable: Back to the start!
