  1. Dissemination of Statistical Data, Publications and Metadata - Process Based on Common Structure of Statistical Information (CoSSI) Harri Lehtinen(harri.lehtinen@stat.fi)

  2. 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. Harri Lehtinen

  3. XML based dissemination - CoSSI • Modules: • Document metadata • Statistical metadata • Processing metadata • Publications • DATA: • Matrices (XDF) • Tables (CALS) • Sparse matrix (KEYS) CoSSI – (www.stat.fi/cossi) Harri Lehtinen

  4. Implementation • Modular DTD system • Document Type Definitions • Use of standards • CALS, XDF, Dublin-Core... • Statistical matrix (statinfo_xdf.dtd):statmeta.dtd, docmeta.dtd, xdf.dtd • Statistical table (statinfo_cals.dtd):statmeta.dtd, docmeta.dtd, cals.dtd • Publications and documents (publication.dtd):docmeta.dtd, statmeta.dtd, statinfo_cals.dtd, figure.dtd... XML • One XML-file -> data and metadata • Multi-lingual documents Harri Lehtinen

  5. Metadata • Statistical metadata • Information vital for the interpretation of numerical statistical information • Document metadataInformation about: • The producer of document • Document’s content • Processing metadata • Information for a software to process data Harri Lehtinen

  12. Implementation to the PC-Axis • Need for the XML format for the PC-Axis • CoSSI-matrix-format is close to the PC-Axis data format and supports also multi-lingual data • Processing metadata for the PC-Axis (pxmeta) • Mapping of PC-Axis metadata to the CoSSI-model statistical, document and processing metadata • Three data formats • Matrix (XDF) • Table (CALS) • Keys (PC-Axis) => but the same metadata for all formats! • Allows more metadata than the original PC-Axis format • Automatical conversion between data formats Harri Lehtinen

  13. CoSSI for the PC-Axis Data part is in different formats but everything else stays the same • Matrix • Docmeta • Procmeta • Statmeta • Data -> XDF • Table • Docmeta • Procmeta • Data -> CALS • Statmeta • Keys • Docmeta • Procmeta • Statmeta • Data -> Keys Information is the same in all formats!

  15. What we need: • More and better metadata • Validation • Language versions • All information in a single file • Archiving • Automatical conversion to different dissemination channels • Structured searches • SVG • Vendor free solution • To add new dissemination channels Harri Lehtinen
