Semantic MediaWiki question this time out. We use SMW at [[w:c:tardis]] to help us control the mind-numbing number of crew members we catalogue. Because ''Doctor Who'' has been running for 50 years, there's plenty of movement in the crew — camera operators become cinematographers, floor managers become directors, etc. But it's almost impossible for anyone to know every position that every crew member has ever held. So what I'm wondering is how to write an SMW statement that will print out a list of ''all'' SMW properties linked to a page — without having to specify all the applicable property names. In other words, I'm looking for a statement with the functionality of "WhatPropertiesLinksHere". Any guesses how to achieve this? {{user:CzechOut/Sig}}{{User:CzechOut/TimeFormat}} 14:56: Tue 18 Sep 2012</span>

:''Is'' that what I want? I'm not sure that it is. I ultimately want the values, too. What I'm really trying to do is create a simple, un-parametered template that people can just plop down on a page and it will then list all the jobs that a person has ever had. Currently what I have is the simple one-job template called [[tardis:template:pcred]]. This allows me to specify the job and I'll get a list. For instance, if I type {{tlx|pcred|director}}, it'll show me every episode on which the PAGENAME was credited as a director. And that's fine and all, but what I need is something where I can just type {{tlx|pcred}}, and it'll give me every job they ever had and every episode on which they had a particular credit.

::''I ultimately want the values, too.'' - No you don't. On your wiki, people are only stored as SMW property values.

Semantic MediaWiki question this time out. We use SMW at w:c:tardis to help us control the mind-numbing number of crew members we catalogue. Because Doctor Who has been running for 50 years, there's plenty of movement in the crew — camera operators become cinematographers, floor managers become directors, etc. But it's almost impossible for anyone to know every position that every crew member has ever held.

What you want is a query for one value over all properties in the wiki. And then display the properties instead of the value…
I reckon, the most you can get is Special:WhatLinksHere with namespace set to Property. Sounds like a DPL thing.--PedroM (talk) 23:13, September 18, 2012 (UTC)
Is that what I want? I'm not sure that it is. I ultimately want the values, too. What I'm really trying to do is create a simple, un-parametered template that people can just plop down on a page and it will then list all the jobs that a person has ever had. Currently what I have is the simple one-job template called tardis:template:pcred. This allows me to specify the job and I'll get a list. For instance, if I type {{pcred|director}}, it'll show me every episode on which the PAGENAME was credited as a director. And that's fine and all, but what I need is something where I can just type {{pcred}}, and it'll give me every job they ever had and every episode on which they had a particular credit.
I know it can't be a DPL thing, because DPL doesn't create a relational database so much as it manipulates categories.

To clarify: In your first post you said "without having to specify the applicable property names", but in the second one you say "given the list of properties on this wiki". Do you have a list of all jobs on doctor who? If there were say, ten, could you not just have a template something like (I dunno the specifics of the code)

{{#if:{{pcred|director}}|

{{#if:{{pcred|producer}}|
===As producer===

etc...
Because presumably if they haven't worked as a certain job, pcred will just return an empty string?--Category:Acer4666 10:22, September 19, 2012 (UTC)

I don't think SMW is designed for what you're talking about - normally the values of properties aren't shared between different properties. If you wanted to do what you're talking about, I think on the episode pages you would have to set it up like
[[Russell T Davies]] was the [[Russell T Davies::Writer]] of this episode
[[Steven Spielberg]] was the [[Steven Spielberg::Director]] of this episode
etc...
ie, make the people the properties and their jobs the values, then you could go to [[Property:Russel T Davies]] and you'd have a list of what episodes he worked on and his job on each one.
