Semantic MediaWiki 1.0

From the RELEASE-NOTES

 * Simplified semantic annotations: just one kind of annotation ("Property").
 * Significant speedup (both server and network load substantially reduced, faster RDF export, more efficient query result formatting).
 * Prettier and easier to understand interfaces:
 * New tooltips for warnings and addtional information.
 * Simplified factbox layout, with all properties in alphabetic order.
 * Inline warnings to simplify trouble shooting with annotations.
 * Improved, more helpful and informative warning and error messages.
 * Highlighting for built-in elements. E.g. built-in types are visually distinguished from arbitrary types; useful as visual feedback.
 * Error/warning reporting for (inline) queries.
 * More powerful output formatting for semantic querying:
 * new parser function syntax for inline queries, fully compatible with MediaWiki templates, template parameters, and parser functions of other extension
 * more readable inline query structure in #ask parser function, printouts separated from query
 * semantic RSS feeds making feeds from query results via "format=rss"
 * new prinout format "?Category:Name" for #ask
 * option to hide main column by setting "mainlabel=-", and reinserting via print request "?" (only for #ask)
 * More expressivity for semantic querying:
 * support for subproperties,
 * improved equality resolution (redirects),
 * support for disjunctions,
 * inequality check for datavalues (" property::!value ")
 * optional pattern matching for string values (" property::~Semant* ")
 * automatic sorting on sort-parameter (no additional condition needed)
 * New/improved datatypes:
 * Type:Page for explicitly specifying properties that are "relations"
 * better media support in Type:Page: special treatment of Image: and Media:
 * Type:Number as universal replacement for Type:Integer and Type:Float
 * Type:URL as universal replacement for old Type:URL and Type:URI
 * Type:Geographic coordinates completely rewritten. More input formats supported, more liberal parsing to accept most inputs
 * special property "allows value" works for all types
 * display units are now easier to select via property "display units"
 * Improved data display: URL-links and tooltips work for queries results and on special pages
 * Improved special pages:
 * simpler interface for Special:Ask, hide query when using "further results" link
 * hints and warning for property usage/declaration in Special:Properties
 * extra information and warnings for types on Special:Types
 * Special:SemanticStatistics as faster replacement for earlier "ExtendedStatistics"
 * Better internationalisation:
 * updates in all translation files
 * new translations to Dutch, Chinese (tw/ch), Korean (beta)
 * alias strings for all SMW elements; English labels are allowed in all languages, names of old SMW elements still work as aliases for their replacements.
 * New experimental n-ary properties, allowing property values to consist of a list of entries.
 * Ontology import re-enabled (simple annotation import)
 * Maintenance script SMW_refreshData now can rebuild all SMW data structures, fixing even exotic database problems on most sites.
 * New maintenance script for announcing site to Semantic Web crawlers.
 * Support for upcoming MediaWiki 1.12
 * Improved APIs and various new hooks to simplify the life of SMW extension developers.
 * Many bugfixes.

Other changes for SMW1.0 include:


 * Type:Enum became obsolete, since all types now suppport "allows value", but it remains an alias for Type:String.
 * Some configuration options for LocalSettings.php have changed. Read INSTALL for details on how to upgrade from your old installation.
