3. Background
200 sets of statistics on 26 topics, 700 data releases per year
All statistics have their own home page and each statistic must also generate information for its page at least each time of publishing -> Electronical publications in different languages on all statistics
The need for an efficient content production system for wide-scale electronic publishing

4. Information architecture
CoSSI: (Common Structure of Statistical Information)
The point of departure in the CoSSI was an (infological) analysis of the information being considered.
The conclusion from the analysis was that although in practice the definition of statistical information has varied according to a given situation and application, in reality statistical information has a certain simplifiable and acceptable universal structure.
The CoSSI describes the general structure that is not dependent on the situation of the statistical information presented in differing formats.
=> CoSSI defines the structures of statistical data, metadata and publications.

5. Information architecture
CoSSI
A modular DTD system, which defines the XML-structure for statistical information
Publications
DATA:
Matrices (XDF)
Tables (CALS)
Sparse matrix (KEYS)
Document metadata
Statistical metadata
Processing metadata

6. XML-based publishing system
System architecture
XML-based publishing system
Based on information in XML-format: CoSSI
Standard XML-techniques: DTD, XSLT, XSL-FO, XPath, XQuery
XML-tools: Arbortext editor, eXist XML-database, Saxon, XEP
Development phase
Implementation project
In use in all monthly, quarterly and yearly statistical publications

10. Future challenges Metadata Multilingual and metadata rich tables
New metadata system based on CoSSI-XML
Integrated variable editor
Integrated classification editor
Quality metadata production and publishing (national needs, ESMS, ESQR)
Processing metadata
Multilingual and metadata rich tables
Interface between metadata and tabulation systems
SAS, SAS-EG (EG Add-In), PX-Edit, .Net-applications
Under development, but slow progress…
