Thread:Extension talk:DynamicPageList (Wikimedia)/Feature request: hCalendar/reply (2)

dtstart is simply the name given to the date parameter. For a duration, one would match it with dtend, but alone it simply marks the date and time at which something happened - in this case, the date the article was added to the category. This would come in useful to people who wanted an easy way to plot various events (e.g. on Wikinews) on a timeline or calendar - while now that would have to manually enter each date and event, this would allow them to simply export (e.g. using Operator) all the hCalendar events on a page, and import the resultant file into their application of choice, which is far easier. Use will, of course, be limited, but it's something some people might want to do (I have done similar things myself in the past, manually), and it has little-to-no impact on other users' experience, other than perhaps a millisecond increase in loading time. As support for hCalendar becomes more widespread, this will have more uses and applications.
