SMW at National Gallery (London)

National Gallery Research is experimenting with SMW for data related to paintings and conservation

• list of all classes (categories) involved. http://research.ng-london.org.uk/wiki/index.php?title=Special:Categories&limit=500
  51 of them are CRM classes, 27 are NG-defined classes (most of them CRM extensions), and there are about 20 not yet created classes (redlinks)
• the class hierarchy is reflected in the category hierarchy http://research.ng-london.org.uk/wiki/index.php/Category:E13-Attribute_Assignment
• indication that the classes ("Category") and properties ("Type:Page") are created throughj automatic import: http://research.ng-london.org.uk/wiki/index.php/MediaWiki:Smw_import_cidoc http://research.ng-london.org.uk/wiki/index.php/MediaWiki:Smw_import_ngex
  • the last page shows 48 ext classes and 81 ext properties of NG, but not all of them are defined
• CRM ext of NG in RDFS format http://rdf.ng-london.org.uk/2012/4/NG_CIDOC_v5.0.4_extra_0.3.xml
• list of all properties http://research.ng-london.org.uk/wiki/index.php?title=Special:Properties&limit=500&offset=0

Now let's take a look at a few specific classes

• class (used as sub-page of another main class) http://research.ng-london.org.uk/wiki/index.php/Category:Condition_Subpage
• form defined for that class http://research.ng-london.org.uk/wiki/index.php/Form:Condition
• form used during editing an instance of that class http://research.ng-london.org.uk/wiki/index.php/Special:FormEdit/Condition/sample_Condition
• an applied class (Easel Painting) that's subclass of a generic class (Museum Object) http://research.ng-london.org.uk/wiki/index.php/Category:EN39-Easel_Painting http://research.ng-london.org.uk/wiki/index.php/Category:EN29-Museum_Object

Now let’s take a look at some instances

• a specific Easel Painting. Notice the DeepZoom representation, the form fields (some of them referring to other pages), and the sub-pages represented as bullets and accessible at hierarchical URIs http://research.ng-london.org.uk/wiki/index.php/NG808
• corresponds to this (and may have been imported from it): http://www.nationalgallery.org.uk/goto/painting.ashx?ID=NG808
• editing this instance http://research.ng-london.org.uk/wiki/index.php?title=NG808&action=formedit
• sub-page about the production of this instance http://research.ng-london.org.uk/wiki/index.php/NG808:_Production

Experimental status:

• the edit form is either not fully functional, or not presented fully to an anon user: http://research.ng-london.org.uk/wiki/index.php?title=NG808&action=formedit
• even a basic search for related objects doesn't work: http://research.ng-london.org.uk/wiki/index.php/Special:SearchByProperty?title=Special%3ASearchByProperty&property=P14F-carried+out+by&value=Giovanni+Bellini

I'm not sure who's doing this work.

• Emmanuelle, do you know? Emmanuelle sent me this link (re a particular modeling pattern): http://research.ng-london.org.uk/wiki/index.php/Category:EN41-Artist_Sub_Group
• Last updates are from 2012.

Jana, this answers some of your questions "How would SMW look to end-users".
But I'm not sure in the best possible light
