Re: [TM4J-users] Possible Tolog bug

[Kal A. <ka...@te...>]

Hi Bret,

For the query:

select $ASSOC, $ROLE1, $ROLE2 from   
  association-role($ASSOC, $ROLE1),
  role-player($ROLE1, AT1),
  association-role($ASSOC, $ROLE2),
  role-player($ROLE2, AT2)?

I tried this with a simple topic map and it parsed correctly. Perhaps
there is something in the topic map. Can you make a minimal case topic
map that fails on this query - if you can let me have such a topic map
for my testing, that would be a great help.

For the query:

select $ASSOC, $ROLE1, $ROLE2 from   
  association-role($ASSOC, $ROLE1),
  role-player($ROLE1, AT1),
  association-role($ASSOC, $ROLE2),
  role-player($ROLE2, AT2),
  type($ASSOC, activity_dependency) |
  type($ASSOC, activity_responsibility)?

The OR part needs to be wrapped in curly braces, so rewrite it as:

select $ASSOC, $ROLE1, $ROLE2 from   
  association-role($ASSOC, $ROLE1),
  role-player($ROLE1, AT1),
  association-role($ASSOC, $ROLE2),
  role-player($ROLE2, AT2),
  { type($ASSOC, activity_dependency) |
  type($ASSOC, activity_responsibility) } ?

and it should parse correctly.

Cheers,

Kal
