Problem: Data in articles is stored in raw text and often unspecifically referenced. That same data is or could be stored and cited from Wikidata and be directly referenced.
Proposed solution:
When editing an article, a system automatically recognizes textual data in articles that could be represented on Wikidata and shows small prompt dialogs by the statements asking the user to convert the text to a template that derives data from Wikidata such as Template:Wikidata (Q8478926). If the statement does not exist on the article's or a related item yet, the system will prompt the user to create the statement and will provide a UI in the article to do so. If reference(s) are nearby the statement, the system will also be able prompt the user if they want to use that reference for the statement.
Example usage: A user is editing Barack Obama. A small dialog box appears above the text/wikitext He graduated with a [[Bachelor of Arts]] degree in 1983 and a 3.7 [[Grading (education)#United States|GPA]]. stating, "This phrase can be converted to be sourced from Wikidata." If the user selects to do so, the phrase will reference this statement on Obama's item and the text/wikitext will be replaced with: He graduated with a {{Wikidata|qualifier|linked|P69|Q49088|P512}} degree in {{Wikidata|qualifier|P69|Q49088|P582}} and a 3.7 [[Grading (education)#United States|GPA]].
Who would benefit: All projects. When statements with references are added to Wikidata, anyone on any wiki can use that data.
