 [Semediawiki-user] properties defined by functions? From: Zeev Pekar - 2010-01-26 14:03:27 ```Hi, is it possible to define properties by functions rather than constants? for example in article about triangle property "Square" would be described by s=0.5*h*l, where h is Height, l is Length with certain range: h:[1..3] step - 1, l:[1..5] step - 1, Square would be described by triples (0.5,1,1) (1,1,2) etc. and then if one searches for geometrical shapes with "Square = 0.5" or "Square = 1 AND Height= 1" or "Square = 0.5 AND Height =1 AND Length = 1", he would get, among others, article about triangle... 1) is such functionality already implemented? 2) is it planned to be implemented in future? 3) is there an extension that does it? 4) is it hard to implement such thing alone? which existing extension should I use in order to implement this feature? thank you in advance, Zeev ```
 Re: [Semediawiki-user] properties defined by functions? From: Philipp Zaltenbach - 2010-01-26 16:03:26 ```Hi, calculation of property values is for instance possible with our Semantic Rules extension, which we released recently [1]. With this you can e.g. express "s" as inferred property and let the value get computed when someone has stated values for the properties "h" and "l". The type of rule you need here are so called "calculation rules" which allow you to define a formula for computing (i.e. inferring) the value of another property.

 Re: [Semediawiki-user] properties defined by functions? From: Zeev Pekar - 2010-01-26 16:21:34 ```great! thank you for the tip. 1) can the values for the h and l be provided in form of ranges with certain step? like h - [1..5], step 0.5? 2) since you write "for instance possible" - are there other ways to get it working? 3) is it possible to have alternative definitions for properties like number for property "population" for certain city according to different sources? 4) is there a handy way to provide sources for different alternative values for the same property? thank you very much!

 Re: [Semediawiki-user] properties defined by functions? From: Philipp Zaltenbach - 2010-01-27 10:10:43 ```Hi, 1) Ranges can only be defined on schema level. For instance you could define that "h" in general shall take in only the values [1..5]. This can be done by making "allows value" statements (see http://semantic-mediawiki.org/wiki/Property:Allows_value). 2) I am not aware of other alternatives at the moment. 3) Could you give a concrete example on how that would look like? 4) I can imagine that this could be achieved via many-valued properties or Yaron's SIO extension.

Page A: [[height::1]] [[length:4]] Page B: [[height::2]] [[length:5]] Page C: [[height::3]] [[length:6]] If you have defined your formula as calculation rule you would then obtain a derived square value for each page.
