What a very interesting response. Let me see if I have this straight: You can't think of any good reason why someone would want to do something, and when someone says they want to, your reaction is to attack their choice of organizing their data? I think the problem may be that you are still thinking wiki, whereas I'm using MediaWiki as a platform for developing a data management system.
So, what is the actual place where I'm trying to do this? I created a Form to help edit Category pages. On the form, I put a dropdown which lists all of the Structured Documents defined in the system. If the user selects a structured document, then the template looks up everything it needs to know from the Structured Document definition page. Likewise, there is a dropdown that lists all of the forms in the system, so you can select the form to use to edit pages in that category (if you didn't select a structured document). The purpose of all of this is to make it easier for non-technical users to define/edit categories.
But the query for forms returns everything looking like: [[:Form:xyz|Form:xyz]], which means that is what shows up in the dropdown. What SHOULD show up in the dropdown is "xyz", as that is all the user needs to see.
But in general, I can think of a million reasons why you would need to populate a dropdown with something other than raw page names.
1. A list of users, displayed as Last Name, First
2. A list of open defects, showing defect ID number followed by the summary
3. All open/active User Stories, listing the user story text
4. A list of teams, taken from their team pages
Bottom-line: There is a very real need to do this kind of thing.
Which means that being "out of luck" means that Semantic MediaWiki is not really ready for prime-time. Is that really the message you want to send to the world?

Hi,No, you can't do any of these things, so I guess you're out of luck.Personally, I think the fact that you're asking about these might indicate a non-ideal data structure, which is why I was asking about data structure before; but that's a matter of opinion.-Yaron--On Mon, Aug 16, 2010 at 6:30 PM, John Arrowwood <John@irie-inc.com> wrote:
The data structure is not important. What is important is that I want to return something other than a page name. The current method of using a concept as inputs to a dropdown does not accept anything other than a page name. Only the page names are used to populate the dropdown, as best as I can tell...
Imagine it like this: Suppose you had a collection of pages, all in the same category. Suppose you wanted to have a dropdown where the values are the page names, but converted to upper case. How would you do that?
How about if you had a collection of pages and sub-pages, and you wanted to return only the sub-page name, without the base page? How would you do that? So if you had "foo/bar" and "foo/blip" and "foo/goo", and you wanted the dropdown to include the values "bar" and "blip" and "goo". How would you do that?
Or if you had a collection of pages in a particular namespace (other than the main namespace), and because it is redundant to show the namespace name over and over again, you want to show the page name without the namespace. Again, the contents of the dropdown should be populated from a query, but the actual appearance of each item should be something other than the actual page names. It might be, for example, an attribute on the page, or a function executed against the page name.
That is the root of the problem. I tried everything I could find to be able to make that happen. The closest thing I could come up with was putting a query on the property page that used a template to control the allowed values. But as you yourself said, then it doesn't update the values unless you 'edit' the property page. That is not a viable alternative. Neither is having to 'purge' the property page.
So, how does one put user-friendly values in dropdowns that are the result of a query? Or can you?On Mon, Aug 16, 2010 at 5:34 PM, Yaron Koren <firstname.lastname@example.org> wrote:
Hi Alex,John - in a sense, this extension might be helpful for you as well; though I'm always sure there's a better way for you to do whatever it is you're trying to do; though, not knowing your data structure, I don't know what that is.-Yaron--On Mon, Aug 16, 2010 at 1:14 PM, Alex Kozak <email@example.com> wrote:
Has there been any discussion about ways around the data update issue? Maybe there could be a way for SMW to run the data repair/upgrade in the background? I've run into this annoyance countless times.

That doesn't sound like a defect - regardless of what you see on the

In any case, that's not the ideal way to do it - you should instead define
an SMW "concept" that holds that query, and then use either "values from
concept" or "autocomplete on concept" in the form input (probably the
