Planning Future planning committee 1998 – Steering Group formed 2004 – Beginning of CMF CMF Guide to future work Tightly focused Interim meetings
Technology Effects on METIS Internet – Before 1996 Paper, FAX – 1998 METIS web site – Web 2.0 Wiki for CMF development
Technology Effects on Metadata Systems Computing power – Dramatic increases Data – 1990 Data on large tapes – Advent of CD Much easier dissemination – Internet FTP, HTTP Other
Technology Effects on Metadata Systems Metadata – For tapes and CDs Focus on data sets, single survey But, theory – broad approach – Internet Connectivity Connection speeds increase Ability to download
Technology Effects on Metadata Systems Metadata – « Active » metadata – Interoperability – Standards SDMX, DDI, etc – Semantic Web Linked data
Terminology Focus throughout history of METIS METIS Terminology Common Metadata Vocabulary (MCV) – SDMX Multi-lingual metadata systems – Thesauri – Taxonomies – Standards ISO 704, ISO 2499, ISO 5788, ISO/IEC Increased formalism
Formalism Early years Mathematical formalism Mid to late 1990s Models – CLASET – CMR – Neuchâtel – Nordic Model XML
Formalism Early 2000s Standards and Models – MetaNet – Neuchâtel variables – ISO/IEC – SDMX – DDI – Others
Formalism Late 2000s CMF – All 4 parts Concept management Semantic Web
Implementation Early focus Data set Survey Mid 90s to Mid 2000s Expansion to statistical office Now Integrated offices US example
Conclusion Bo Sundgren Retired – Sept 2009 Huge influence METIS17
