View source for Template:Infobox U.S. state1

<noinclude>This is a greatly simplified adaptation of the template from [[wikipedia:{{FULLPAGENAME}}]].

This version embeds semantic annotation inside the template, so the template both displays information in a table and records semantically meaningful properties.
Such [[Help:Semantic templates|semantic templates]] simplify adding semantics to recurring elements in wiki pages.

Note this table does not handle missing values for Population and Area.
That can be done using <tt><nowiki>{{#if:}}</nowiki></tt> from the MediaWiki ParserFunctions extension,
but using conditionals in a table requires tricky syntax to mix pipe ' '''|''' ' symbols for layout and expressions (see [[wikipedia:Wikipedia:Conditional_tables]]).

The table appears below in this template page (we could hide it with <nowiki><includeonly></nowiki>).  You don't see any factbox for this dummy table because in this Semantic MediaWiki installation, semantic annotations are not enabled in the Template namespace.</noinclude>
