Dr. James David Mason (ISO/IEC JTC 1/SC 34 Secretariat - Standards Council of Canada) Crane Softwrights Ltd. Box 266, Kars, ON K0A-2E0 CANADA Telephone: +1 613 489-0999 Facsimile: +1 613 489-0995 Network: jtc1sc34@scc.ca http://www.jtc1sc34.org |
This document collects solutions to the TMQL use cases in different languages into a single document for comparison purposes. The idea is that seeing how these use cases are solved in different languages will allow readers to compare the languages and get an idea of the strengths and weaknesses of each, in order to help the committee make an informed decision about how to proceed with the TMQL standard.
This document contains solutions to 29 use cases in the following languages:
| Query language | Solutions |
| AsTMa? | 29 |
| TMPath | 27 |
| Toma | 27 |
| tolog | 25 |
The following solutions are samples only; in most languages there are several ways to achieve the goal of one and the same query. These solutions might therefore differ considerably in length and complexity, depending on the trade-off between conciseness or readability. Some solutions only may demonstrate language features.
It should also be noted that what this survey shows the most clearly is differences in syntax. However, syntax is easily adjusted, and what really needs to be compared are the evaluation models. Therefore one important consideration is the extent to which the syntaxes should and could be changed.

Retrieve the topic identifiers of all documents which are not written in the language English
function test (map $m) as list return {

return !$Doc1/id
}
select $document.id where is-author-of->opus = $document
and $document.oc(language) != 'english';
The above syntax is implemented in the prototype but fails because of
the bug with negation. So, for example, the opposite query is possible:
select $document.id where is-author-of->opus = $document
and $document.oc(language) = 'english';
instance-of($DOCUMENT, document), not(language($DOCUMENT, "english"))?
Retrieve the topic identifiers of all documents which are directly or indirectly influenced by something which Steve Pepper wrote

forall [ (is-influenced-by)
influence : $e
influenced: $d ]
return
{$d + influents($d)}
}
return {
forall [ (is-author-of)
opus : $d
author : $influencer ]
return {
forall $e in influents($d) return {
($d, "influenced by", $e)
}
}
}
[transitive=true]
define step has-influence-on()
{
$$self/roleOf::target@$$scope[influenced-by]/role::source
}
define step authored-by()
{
$$self/roleOf::opus@$$scope[is-author-of]/role::author
}
list{
for $Doc1 in /topic[*; authored-by=pepper]
let $Docs:=$Doc1//has-influence-on
for $Doc2 in $Docs
where not(empty($Docs))
order by !$Doc2/id
return
list{!$Doc2/id,'influenced by',!$Doc1/id}
}
OK, this is quite pre-mature issue in Toma. I am not sure yet exactly
how functions will be used. In the following example, I use the rule
that functions can take only strings as input (and not
objects). Probably this should be changed (although this simplifies
things).
define all_influenced_by(&influence_id) {
select $influenced.id
where is-influenced-by->influenced = $mid
and is-influenced-by->influence = $influence
and $influence.id = '&influence_id'
and ($influenced = $mid
or $influenced = all_influenced_by($mid.id));
}
select $influenced.id where is-author-of->opus = $influence
and is-author-of->author.bn@uc = 'Steve Pepper'
and all_influenced_by($influence.id) = $influenced;
indirect-influence($INFLUENCED, $INFLUENCE) :- {
is-influenced-by($INFLUENCED : influenced, $INFLUENCE : influence) |
is-influenced-by($INFLUENCED : influenced, $MID : influence),
indirect-influence($MID, $INFLUENCE)

indirect-influence($INFLUENCED, $INFLUENCE),
is-author-of($INFLUENCE : opus, steve-pepper : author)?

# it is not totally clear to me what is the meaning by sub class
# and super class in the context of this exercise. from other
# solutions I understand that you have hirarchy of instanceOf
# (so the operator to find the isntanceOf is used also for
# super-classes - sub-classes relationship, but I thought that
# this should be a different operator (as it is different
# relationship).
select $topic.id where $topic.type(1).id in ('journal-paper',
'conference-paper',

Retrieve all titles of all publications (regardless their scope) together with their most specific class
function test (map $m) as list return {

As stated in the mailing list, I would prefer to see the creation of
XML outside of the language. However, as it was requested in this
document, I provide one way to implement XML generation:
