Building OECD’s New Statistical Information System Lee Samuelson

New OECD Statistical Information System § Core element of OECD Strategy for Statistics § § § Increase the efficiency of statistical processes Improve the quality of statistical data and metadata -- notably timeliness and coherence Enhance the accessibility of OECD statistical resources for both internal and external users § Encompasses all aspects of statistical activities

A cooperative effort Producers of statistics Users of statistics n n OECD staff External clients PAC, ITN and STD n n n Manage projects Supply infrastructure Provide support

SIS Design Principles § Preserve the decentralised nature of directorates’ statistical activities. . . while making their data part of a coherent corporate system § Build component elements that can function independently …… and which are fully interoperable with each other § Make innovative use of emerging technology standards (e. g. , XML, Web Services, SDMX)

Three Inter-operating Layers …. Production layer n n Stat. Works – modern production environment Meta. Store – coherent management of metadata Storage Layer n OECD. Stat – validated data and metadata Dissemination layer n n User interfaces Pub. Stat – publications management …. Supported by a Work. Flow system

SIS Architecture Production Storage Data Production Environments (incl. Stat. Works) Dissemination OECD. Stat Corporate Data Cubes Warehouse User Interfaces Pub. Stat Meta. Store Metadata Production Environment XML Web Services Work flow Publication Management Interface Published Outputs

Overall goals (1) User friendliness n n n One-stop database Easy access Common “look and feel” for all products Efficiency n n n Common tools Easy access across OECD Review of processes

Overall goals (2) Quality n n n Coherence of concepts & data Timeliness Good metadata Visibility n Greater visibility of statistical products Flexibility n Separate storage, processing, dissemination

Metadata Principles Statistical data being shared or disseminated, internally or externally, must have appropriate metadata Statistical metadata must be consistent Metadata must be created only once For each dataset there must be someone with responsibility for metadata

Implementation May 2004 Summer 2004 End 2004 2005 OECD. Stat v. 1 in production Stat. Works v. 1 in production Pub. Stat pilot Government Debt Pub. Stat v. 1 launched Meta. Store v. 1 launched Principal databases in OECD. Stat v. 2 launched All key databases in OECD. Stat Work flow v. 1 launched
