Atle Alvheim Luxembourg October 2006 Assistant Director Norwegian Social Science Data Services Assessing the feasibility of micro-data access
Norwegian Social Science Data Services (NSD)
There is a lack of Tools for thought time spent on digesting and thinking time spent on finding and accessing )( Maximize Much more time went into finding or obtaining information than into digesting it Dr. J.C.R. Licklider
Only a fraction of data resources available on line Lack of standardization Poor integration between data and metadata Institutional, legal, and commercial obstacles All empirical data available on-line An integrated gateway to be used to integrate and locate relevant resources The ability to browse, visualize, and analyze data on-line Hyperlinks from data to relevant scientific publications and resources Empirical feedback system to build the collective memory of a data collection Situation to-day Situation tomorrow?
What are we looking for? Data MetadataTools Data Sharing
Why are metadata important? Unlabeled stuffLabeled stuff The bean example is taken from: A Managers Introduction to Adobe eXtensible Metadata Platform,
The functions of metadata Finding Understanding Assessing Sharing
An international XML-based standard for the content, presentation, transport, and preservation of documentation Benefits of the DDI Approach Interoperability Richer content Single document - multiple purposes On-line subsetting and analysis Precision in searching Codebooks can be exchanged and transported seamlessly, and applications can be written to work with these homogeneous documents. Providing the data analyst with broader knowledge about a given collection. The codebook contains all of the information necessary to produce several different types of output. DDI documents are easily imported into on- line analysis systems, rendering datasets more readily usable for a wider audience. Field-specific searches across documents and studies are enabled. Data Documentation Initiative (DDI)
A life-cycle model of data Study Concept Data Collection Data Processing Data Distribution Data Discovery Data Analysis Data Archiving Repurposing Combined life cycle model
A common European data portal Metadata is all about communicationMetadata Madiera: A set of tools, + an idea:Madiera Data is a kernel that facilitates a discussion Maybe future libraries consist of datasets with linked or derived knowledge-products, books, papers, tables, etc, wikiswikis Could we imagine libraries of hypoteses ? Libraries of questions and discussions more than of answers ?
What was the specified MADIERA Objectives ? The development of an integrated and effective distributed social science portal to facilitate access to a range of data archives and disparate resources. WP3 The development of specific add-ons to existing virtual data library technologies, in particular data location technology WP4 The employment of a multi-lingual thesaurus to break the language barriers to the discovery of key resources. WP5 An extensive programme to add content, both at the data/information and knowledge levels. WP6 Extensive training of data providers and users to encourage the continuos growth of the infrastructure WP7
A Web of the Social Sciences Building on a distributed model where data and resources are stored and maintained locally For the end user the system will appear as a integrated system A virtual data library offering global access to locally supported data holdings End users Data providers
What is then necessary to develop useful procedures ? Metadata standards lift data from digits to research information Technical solutions, software: Information- and access systems, in addition to analysis and download possibilities Political agreements, conditions for data access Economic agreements, logging, audits
EXAMPLE A common resource European Social Survey (ESS) europeansocialsurvey.org ess.nsd.uib.no An academically driven social survey designed to chart and explain the interaction between Europe's changing institutions and the attitudes, beliefs and behaviour patterns of its diverse populations.
ANOTHER EXAMPLE: Aggregate data The determinants of active civic participation at European and national level (CIVICACTIVE) nsd.uib.no/civicactive
A third example: a common entry-point madiera.net The MADIERA project has developed an effective infrastructure for the European social science community by integrating data with other tools, resources and products of the research process.
A scheme A Finnish researcher Attitudes towards Immigrants (A problem area) An Irish researcher Data on Finland (A geographic area) A Swiss researcher Eurobarometer (A data collection) A registration procedure, register with home archive Look up and access data across holdings
A Data-archive Political Context for 20+ national archives I.It might be money involved Is the data a free or commercial good ? There are categories of users, what about non-academic use, non-CESSDA use ? Who are to fix the prices ? II.Varying Access rules. The crossing of national borders What laws apply. Who set the rules Who is responsible ? What sanctions available ? III.There are some Common good data Eurobarometers, Value studies, ISSP, ESS, Comparative collections Could best be provided from one single point (?) Charging ? Access Conditions ? Double Storage ? IV.It is a good thing to have national archives, enhances amount of data available and betters the accessibility. Need justification and visibility
