Semantic MediaWiki
leaves your MediaWiki installation intact
no patching, just a (bunch of) MW extension(s)
already existing unstructured content can stay as it is or be
transformed
gives you all the tools you need for a
collaborative web database
entering data and text
representing/visualising data and text within the wiki
re-use/export data outside the wiki
everything is done through configuration
Attributes, Forms, Templates, Filters… are wiki pages
Queries, parsing, “programming” via Wikitext

> 40 different „result formats“

Outlook
Data-Import from a

Memorial Signs
Politics of Remembrance
and the Transition of
Public Spaces. (POREM)
Improved version of
filtered format for a filter

SMW 2.3.1 -> 2.5.x

Challenges
Performance!
especially large queries
Very limited access to production server
runJobs.php only run once a day at 22:00, $wgJobRunRate=0
SW-Upgrades are expensive
external tests: performance/security – no code reviews
see what has been „officially approved“

https://github.com/JeroenDeDauw/Maps/ needs some love
Data integration in official
Vienna Map

Extension:External_Data

Proposal for hack days:
Test new filtered format - map
Install Semantic Result Formats with composer
Change to directory .../extensions/SemanticResultFormats
git pull https://github.com/s7eph4n/SemanticResultFormats.git filtered
Change in MW install directory:
composer dump-autoload
New view „map“ and filter „number“ should be available in filtered result format
Basic documentation
https://github.com/s7eph4n/SemanticResultFormats/blob/filtered/formats/filtered/README.md
This should work
{{#ask:[[SomeCondition]]
|? SomePrintout |+filter=number
|? Position
|format=filtered
|views=map
|map view marker position property=Position
}}
