OK, I added my response there ( http://ontoworld.org/wiki/Talk:N-ary_relations#Too_complicated.2Fconfusing_and_just_unnecessary ), with more info and an example.

The relationships/attributes/properties (whatever) are too wordy. Instead, these are shorter and more grammatically correct, shorter, less syllables, faster to type, etc: has president -> president begin of term -> term begin end of term -> term end location -> place Also, with the new property, er, property (attribute? option? parameter?), will it work like relationships do now with [[relationship::name]] where the "::" (double colons) create a link where as [[attribute:=name]] doesn't create a link? I ask because I need that functionality for both parameters ("relationship" and "attribute" in SMW .7) and I hope "property" can do both links and non-links as well for the next SMW version. Last, if "property" can also accept just "prop" that would would make it easier to use (and type)--"rel" and "att" could be shortened forms of the current parameter names too.

Note that in the following example we get a much better ontology: = BEGIN ========================================== [[has president:: [[Person::John F. Kennedy|John F. Kennedy]] started to be president in [[begin of term:: [[Year::1961|]] ]] and was [[end of term:: [[Reason:: [[Type::assassination|assassinated]] in [[Location::Dallas|]] by [[by::Lee Harvey Oswald|]] on [[Date:=1963-10-22||November 22, 1963]] ]] ]]. After Kennedy, [[has president:: [[Person::Richard Nixon|]] started to be president in [[begin of term:: [[Year::1969|]] ]] till [[end of therm:: [[Year::1969|] ]] then the was rejected and started his term again in [[has president:: [[Person::Richard Nixon]] [[begin of term:: [[Year::1969|]] ]] but [[end of term:: [[Reason:: [[Type::resignation|resignated]] because of the [[Because::Watergate scandal|]] on [[Date:=1974-08-09|August 9, 1974]] ]]. Since [[has president:: [[begin of term:: [[Year:2001|]] [[Person::George Walker Bush|G. W. Bush]] ]] ]] won the election and is therefore the current president. = END ============================================= Note that I can mix ordinary text with markup (a <nowiki> or <nosemantic> element might be possible too, but then the source becomes even harder to read) and there is no need to keep the format - If I want to do so I can use Templates, but that comes with a loss of flexibility if the template is not well scripted: {{has president|John F. Kennedy|1961|1963|assassinated}} Also a vertical bar right before the closing brackets will repeat the text that is given as argument. Relations marked with :: and having a non-complex value will get interpreted as Link to an Article. Anyway, I would take this only as example, because the starts and ends of being president might be better placed into the articles of the presidents - but this is a very subjective POV. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
