Hello!

I ran across a problem with TM package.

When converting an astma2.0 topic map to xtm, I get an error at the Serializable ("TM::Serializable::XTM").

The Error is:
"Use of uninitialized value in string eq at /usr/local/share/perl/5.10.0/TM/Serializable/XTM.pm line 601 during global destruction."

At the end of the post I included my testcode.

Is there any solution to this?
I think it is vital to convert astma to xtm files.

Thanks for any help.
Stephan

##CODE:

use TM::Materialized::AsTMa;
use TM::Tau;

use Data::Dumper;

use File::Slurp;

## adapted from http://cpansearch.perl.org/src/DRRHO/TM-1.49/examples/02_astma.pl

$astmacode= '
%version 2.0

rho isa person and has name : "Robert Barta" .
rho has blog : http://kill.devc.at/ .

## much more is possible here

';

write_file( '/tmp/test.atm', $astmacode ) ;

$tm = new TM::Materialized::AsTMa (file => '/tmp/test.atm');
$tm->sync_in;

print Dumper $tm; ## works!

## from http://search.cpan.org/~drrho/TM/lib/TM/Tau.pm
## convert between different formats
$tm = new TM::Tau ('file:/tmp/test.atm > file:/tmp/test.xtm');

## results in the ERROR:
## Use of uninitialized value in string eq at
## /usr/local/share/perl/5.10.0/TM/Serializable/XTM.pm line 601 during global destruction.

I need to learn a lot, because I can hardly follow the examples in "t/045astma2fact.t" yet.

thank you for the hints

Today I am writing a short update and regarding a note on TM::Bulk with 'associations'.

I programmed a small REST server (or 'rest approximation') with the TM module.

It works like a charm. Nice is the combination of the tm-rest-server with a XProc rest-server (XProc= xslt pipelines).
The topic map server gives back xml wich is transformed via the XProc-rest-server in anything else, e.g. html.

It might not be a solution for everyone (it uses xml!) but it does the job for me.

Regarding 'TM::Bulk' with 'associations':

I found out that $tm->vortex() honors 'associations'.
I looked at the source code at:
http://cpansearch.perl.org/src/DRRHO/TM-1.50/lib/TM/Bulk.pm

However the documentation for 'TM::Bulk' doesn't mention that (and that it's possible to get a hash for the associations).

So my guess is that either the documentation is not up to date, or it's because there are currently no test cases for associations (in TM::Bulk) and therfore it's not in the documentation.

Stephan

ps: If anyone is interested in the code:

##Asma-Testcase:
yyy << xxx ( role1 : aaa bbb , role2 : ccc )

## dump result for the vortex
my $vortex = $tm->vortex($local_id,
{
'topic' => [ 'topic' ],
'associations' => [ 'associations' ],
'roles' => [ 'roles', 0, 10 ] },
);
print Dumper $vortex;

##result:
$VAR1 = {
'topic' => [
'tm://nirvana/ccc',
undef,
[]
],
'roles' => [
'tm://nirvana/yyy'
],
'associations' => [
[
'tm://nirvana/xxx',
'us',
'tm://nirvana/role2',
{
'tm://nirvana/role1' => [
'tm://nirvana/aaa',
'tm://nirvana/bbb'
]
}
]
]
