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 13250• 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 11179– SDMX– DDI– Others
Implementation Early focus
Data set Survey
Mid 90s to Mid 2000s Expansion to statistical office
Now Integrated offices US example
