Hello,
I was at a meeting with editors of a LocalWiki called FürthWiki and they use SemanticMediaWiki and then I saw how they edit the data with forms. I think that a form is a helpful thing for editing data. In Wikidata it is currently possible to use it for creating new items with WikidataCradle. Do you plan to offer forms for creating items in a further version. For example a mayor of a city is a example where a item about it does usually not exist in a little village before the election. So this is something what has to be created when editing the value in the Infobox. Have you plans how you want to solve this.
