  10. Some practical issues • Incomplete data – to fill or not to fill? • Structural changes without notification (e.g. EUR-Lex descriptors) • Encoding problems (language related) • Poor to non-existent PSIH level support

  11. Adding value, maintaining data integrity • Integrating information- all in one place • Building taxonomies – relational indexes • Enhancing search capabilities – legal synonims, suggested spelling • Providing customer support

  12. Positive developments • more structure • better standards • Supreme Court – unified structure across different courts (supreme, appelate, administrative) • Constitutional Court – from structured text to XML • EUROP – ftp site, new XML format

  15. Conclusions • Direct relationship between PSI quality and commercial re-use viability • Better quality PSI (structure, standards) more time to add value – less parsing etc. • Wider use of relational databases desired (simple extractions), mapping of data
