Semantic MediaWiki 2.5
Released on March 14, 2017.
Highlights
Full-text search support
Support for full-text search was added using the native capabilities of the SQL backends "MySQL"/"MariaDB" (#1481) and "SQLite" (#1801) for the "Text", "URL" and "Page" datatypes.
Provenance data recording
Qualifying facts using a simple provenance model is now supported (#1808) using existing mechanisms in defining a property specification together with a new "Reference" datatype (video).
Property chain and language filter support in print request
Property chain for conditions (e.g [[Located in.Capital of::Foo]]
) was provided for some time, and now got extended (#1824) to supporting the syntax on print requests to retrieve values of a chain member that represent a page node. Values of datatype "Monolingual Text" can now use a language filter (#2037) to restrict the display of a value in a print request.
Edit protection
Edit protection to help avoid changes to properties or other data sensitive pages from alterations that may cause data invalidations (e.g. change of a property type, inconsistent specifications etc.) or process disruptions. This feature integrates with MediaWiki's page protection functionality.
Preferred property label support
Semantic MediaWiki now supports the declaration of preferred property labels (#1865) with the objective to show labels in a user context on special pages, query results, and factboxes instead of the canonical property label.
Query result cache
Caching of query results (#1251) was added as experimental feature to minimize a possible impact of query processing during and after a page view. This change also includes a reevaluation (#2099, #2176) of the query hash (used as identifier) to ensure that cache fragmentation is reduced and duplicate queries can share the same cache across different pages.
Links in values
Support for links in values for datatype "Text" was extended by use-cases and improved in performance as well as avoiding the former error-prone "PCRE-approach".
Fixed properties
Support for fixed properties was overhauled, fixed (#2135) and is no longer experimental.
Special page "SemanticMediaWiki"
Special page "SemanticMediaWiki" formerly known as special page "SMWAdmin" was modernized and extended (#2044, etc.) including a new configuration setting allowing for a more fine-granded control over feature accessibilty (#2142).
Compatibility changes
- Minimum requirement for PHP changed to version 5.5 and later
- Minimum requirement for MediaWiki changed to version 1.23 and later (1.27 and later recommended)
- Forward comatibility with MediaWiki 1.29+ adjustments which include #2149, #2198
Upgrading
This release requires to run update.php
or setupStore.php
to add an extra table column for the URI table (#1872) and a new table for the preferred label property (#1865).
