Hi,

 

Thank you very much for pointing me to Semantic Internal Objects.

SIO is a very interesting extension that I unfortunately somehow
overlooked until now.

 

After creating Internal objects like the following three for my friend
Steven McCoy

 

{{#set_internal:Has position

|Has title=CFO

|Has startdate=2003-01-01

|Has enddate=2004-04-01

|Has company=RBI

}}

 

{{#set_internal:Has position

|Has title=CEO

|Has startdate=2002-01-01

|Has enddate=2003-04-01

|Has company=KPN

}}

 

{{#set_internal:Has position

|Has title=CTO

|Has startdate=2005-01-01

|Has enddate=3000-01-01

|Has company=V&D

}}

 

I can successfully query for current and past positions of a person (and
also make lists of current employees and former employees at the pages
of the companies)

 

=== current positions ===

{{#ask:[[Has position::{{FULLPAGENAME}}]][[Has
enddate::>{{CURRENTYEAR}}-{{CURRENTMONTH}}-{{CURRENTDAY}}]]

|mainlabel=-

|sort=Has startdate

|? Has startdate 

|? Has title 

|? Has company 

}}

 

=== previous positions ===

{{#ask:[[Has position::{{FULLPAGENAME}}]][[Has
enddate::<{{CURRENTYEAR}}-{{CURRENTMONTH}}-{{CURRENTDAY}}]]

|mainlabel=-

|sort=Has startdate

|? Has startdate 

|? Has enddate =

|? Has title 

|? Has company 

}}

 

This is great! Really great!

 

I am still struggling though, with making a list of co-workers of a
person. Somehow I need to compare startdates and enddates of people
(within one company). Can I use subqueries (<q></q>) somehow, or do I
need some other mechanism that I can't seem to stumble upon.

 

===Co-workers of Steven McCoy at KPN===

{{#ask:[[Has position::+]] [[Has company::KPN]] [[Has startdate::<
<q>...Steven McCoy's enddate at KPN</q>]] [[Has enddate::> <q>...Steven
McCoy's startdate at KPN</q>]]

|mainlabel=-

|sort=Has startdate

|? Has startdate 

|? Has enddate =

|? Has title 

|? Has company 

}}

 

The other thing is that - In order to keep things dynamic - I need to
get red of the hard-coded [[has company::X]] in the example above and
loop over the results of the list of companies that Steven McCoy worked
for.

 

Thank you very much in advance.

 

Kind regards

EdgarS

Hi Edgar,

 

I would strongly discourage you from creating a page for each of these
combinations of data, and instead strongly encourage you to use the
Semantic Internal Objects extension:

 

http://www.mediawiki.org/wiki/Extension:Semantic_Internal_Objects

 

If you're using Semantic Forms to input the data, you should use
"mulitple-instance templates" to enter that internal-object data.
