Ah, sorry, I haven't read the specs (carefully).

Nevertheless it seems to me, that tm4j does not implement them.
I think we should mention this in the docs.

Thanks, Kal. That was exactly what I wanted. I'm not quite sure how I missed seeing that method
myself.

Cheers,

Hi Richard

The method you want is Topic.setSubject(Locator).

See http://tm4j.org/org.tm4j.topicmap.Topic.setSubject_Locator_.html

[TM4J-users] Creating <resourceRef> within <subjectIdentity>

[<ric...@ya...>]

Hi All,

I've just been reading an article by Steve Pepper [1] on how topic maps have two ways of assigning
subject identity (and how this could be applied to RDF), to distinguish addressable and
non-addressable subjects. Addressable subjects can use <resourceRef>:

<subjectIdentity>
   <resourceRef/>
</subjectIdentity>

and to distinguish, non-addressable subjects can use <subjectIndicatorRef> top refer to a PSI

<subjectIdentity>
   <subjectIndicatorRef/>
</subjectIdentity>

The only method I have found in tm4j is topic.addSubjectIndicator() which add a subject indicator
to a topic with: 
  
<subjectIdentity>
   <subjectIndicatorRef/>
</subjectIdentity>

Is there any way, with tm4j, to create?

<subjectIdentity>
   <resourceRef/>
</subjectIdentity>

Thanks,

Richard

It's grown a bit today, but it's roughly 900k bytes. 3000 topics, most with
1 name, about 100 associations (or about 3000 if you count "instanceOf"
associations), and about 20 occurrences. Very soon it will be enlarged to >
10k topics and probably 20k associations.

RE: [TM4J-users] slow tm export

[Conal T. <Con...@vu...>]

Thanks Kal!

I opened a transaction before walking my topic map, but sadly it hasn't =
speeded it up at all :-(

Here's the code I used:

	/* get the topic map from the topic map manager */
	var TopicMapManager =3D =
cocoon.getComponent("org.tm4j.tm4web.cocoon.TopicMapManagerComponent");
	var map =3D TopicMapManager.getTopicMap("nzetc");
	cocoon.releaseComponent(TopicMapManager);

	/* write the topic map to a file */
	var walker =3D new Packages.org.tm4j.topicmap.utils.TopicMapWalker();
	var writer =3D new Packages.org.tm4j.topicmap.utils.XTMWriter();
	var file =3D new java.io.File(export_filename);
	var os =3D new java.io.FileOutputStream(file);
	var of =3D new Packages.org.apache.xml.serialize.OutputFormat();
	of.setEncoding("UTF-8");
	of.setIndenting(true);
	of.setIndent(2);
	var serializer =3D new =
Packages.org.apache.xml.serialize.XMLSerializer(os, of);
	walker.setHandler(writer);
	writer.setContentHandler(serializer);

	var txn =3D map.getProvider().openTransaction();
	try {

[TM4J-users] PanckouckeContext.getAbstractorIDs()

[George T. <geo...@fr...>]

Hello,
when I call PanckouckeContext.getAbstractorIDs (),
I get only
"compact", and "extended"

what is the meaning of having registered the abstractors in the Panckoucke
Context for the moment?

Re: [TM4J-users] Configuring TMNav to load TM from hibernate

[Christoph F. <cf...@fo...>]

Hi Conal,

this seems to be a bug in tmnav.

Expected behavior is, that after opening the provider (which happens
during startup) all topicmaps that are provided by this provider should
be accessible automatically through the "loaded topicmaps panel".

This works for me locally with postgres but you are the second who is
reporting this problem with mysql. 

I'll check that.

Re: [TM4J-users] Configuring TMNav to load TM from hibernate

[Christoph F. <cf...@fo...>]

Hi Conal, hi Tobi

I found the bug, removed it, and made a new release. 
TMNav 0.2.9pre1. It's in the tmnav-development branch.[1]



The format of some of the entries in the config files did change in
0.2.9. Furthermore I reorganized the package structure, which means that
the renderes can't be found under there former classnames.

To work with 0.2.9, please do the following:
- rename your .tmnav-directory
- start 0.2.9. once. TMNav will create new default config files in the
.tmnav directory. (It might be a good idea to supply the -f option for
the first startup. -f resets all settings from previous sessions, but
I'm not sure if it is really necessary) 
- quit tmnav.
- add your changes to the new config files (the syntax for the provider
element did not change. You should be able to just copy it.)
- restart 0.2.9


I hope this version will do it for you

bye
c


[1] I made the mistake to upload a false binary version, and I'm not
allowed to overwrite it. Instead I have to wait 24 hours until it is
purged from the upload server. This means that I will add the binary
tomorrow to the release.

Re: [TM4J-users] slow tm export

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

Hi Conal,

My guess is that the walk is just doing to many transactions. If you
don't have an "outer" transaction wrapping that walk, then each call to
the API will result in a separate transaction against the database -
which amounts to quite a lot of transactions to walk the whole map.

What I would recommend you try is creating a transaction to wrap around
the walk. If a transaction is already in progress, then the TM4J
Hibernate code will use that txn instead of creating one.

The code would be something like this:

ProviderTransaction txn = provider.getTransaction();
try {
  walker.walk();
} finally {
  txn.abort();
}

Hopefully that should give you a major increase in performance as it
will reduce the number of transactions used and allow client-side
caching done by Hibernate to be effective.

Cheers,

Kal

[TM4J-users] Configuring TMNav to load TM from hibernate

[Conal T. <Con...@vu...>]

I have configured TMNav to add the hibernate provider. WHen I go to the =
"manage providers" dialog I can see the Hibernate provider, and when I =
select it I can see the locator of my topic map. But how do I load this =
topic map? If I type this (http) locator into the Load dialog box then =
TMNav tries to load the topic map via http. But my map is already inside =
hibernate, and I just want to visualise it. What am I doing wrong?

Cheers

[TM4J-users] slow tm export

[Conal T. <Con...@vu...>]

I am developing an application which uses tm4j with Hibernate as the =
provider.=20

The application is a website built with Cocoon. The topic map is =
harvested from a bunch of sources, and defines the information =
architecture of the site. Each page on the site represents a topic with =
all its associated topics and other characteristics. So each page =
requires querying for a few topics only. This works OK.

My problem is that I also want to be able to visualise the entire map, =
to check my harvesting/merging/etc; to do this I've exported the entire =
map, and it takes about an hour (on a 2.6GHz P4 with 2GB RAM). This =
seems like a long time to export 838kb of XTM code containing about 2800 =
topics, but only a few dozen associations. Is this to be expected? Or is =
there something peculiar in this? The MySQL database is local, and the =
export is definitely processor-bound. About 97% of the processor time is =
used by Tomcat (which is the container in which tm4j is running), and =
the remainder is used by MySQL.=20

Some people have reported very slow performance with IMPORTING into =
hibernate - I haven't noticed that. Certainly it takes only a minute or =
so to harvest all these topics (which includes transforming them from =
other XML formats into XTM) and insert them into tm4j.

I see now that it's possible to configure TMNav to use the hibernate =
provider - so maybe I don't need to do this export at all. I don't know =
if this will speed up the visualisation - I'm certainly going to try =
that, but I'm still keen to hear if someone can tell me I'm doing =
something wrong - especially if it's something small and easy to fix :-) =


I'm appending the JavaScript code which does the export, calling Java =
classes to do the actual work. This code runs inside of Cocoon, as a =
"flowscript".

Thanks

Con

RE: [TM4J-users] Some ideas for *cross* TM navigation with TM Nav

Hi Harald,=20

Sounds great !
I hope such things are possible
Unfortunately I'm not a programmer and I can't help you to implement =
such
features.
If you need more precision about those ideas ...

Re: [TM4J-users] Some ideas for *cross* TM navigation with TM Nav

[Christoph F. <cf...@fo...>]

Hi Bernard

that sounds pretty interesting and I think it's closely related to the
task that Bret is facing currently: How could the visualisation of a
given TopicMapObject or a bunch of topicmap objects be more easily
customized.

I think this alludes to several topics:

1. Panckouckes abstraction process should be conceptually divided into
at least two chunks:=20
The first (S1) is to "extract" the relevant TopicMapObjects from the
Topicmap.=20
=20
The second (S2) is to transform the extracted Objects into a Model that
is suitable to be displayed by renderers.
=20
Both stages should be customizable. A TologAbstractor for example may
always perform a TologQuery to extract objects (S1), but how they are
transformed into a model could be up to a ModelBuilder that is passed
into the abstraction process.=20



2. The renderers must be openend for customisation as well. Some simple
solution would assign icons to Gestalten via a HashMap and pass this map
into the Graph-Renderers. Just for the beginning



3. TMNav needs elements (both conceptual and gui) to assemble a bunch of
settings that influence the abstraction and the rendering.=20

3a. Theese 'assemblies' should either be applied automatically to an
abstraction demand or they should be chooseable by the user.

3b. In order to apply them automatically we need some general
rule-mechanics that enable us to express directives like 'a topic of
type X' or 'all topics that has an occurrence of type Y'. Maybe we could
use a tolog query here...


Sounds really interesting and it would be certainly great to have it.=20
But we have to concretise it a bit more...

Anayway, thanks for the suggestion. If you already thought further, I
would be glad to hear it


Bye

You should not be able to use a slash as part of the ID of a topic - the 
ID should match the production for an XML ID (which only allows letters, 
numbers and a small range of other characters). So that means that you 
cannot use the slash character in that way. You can use an underscore 
character, so father_son and status-of_has-status are allowed. Most of 
the time I choose a single name e.g. has-status or parent-of

The i"<uri>" means that the quoted uri is treated as a subject indicator 
to lookup the topic. If you have a topic with ID "test" in the file 
"myTM.xtm", then you can look it up by its *source locator* which 
requires you to use s"<uri>". For more on this, see the Ontopia tutorial 
for tolog (the section is 
file:///C:/kal/dev/oks-professional-2.0.3/doc/query/tutorial.html#sect-topic-ref).

[TM4J-users] tolog queries

[<Ste...@sw...>]

Hi
=20
I have the following two questions using tolog:
=20
[1]
I would like to define a topic like "status-of/has-status" or
"father/son", means with a slash in its name. Wouldn't it possible to
query an association which is a instance of such a topic? E.g. select $A
from father/son($A,$B) ?
=20
Is there a way to tell the parser that this slash is part of the name?=20
=20
[2]
In test classes of tm4j-0.9.4 I found the following query:
=20
select $A from
i\http://www.topicmaps.org/xtm/1.0/core.xtm#class-instance\
(shape:i\"http://www.topicmaps.org/xtm/1.0/core.xtm#class\",
$A:i\"http://www.topicmaps.org/xtm/1.0/core.xtm#instance\") ?
=20
I think such a query works with local files as well. Which syntax I have
to use? Select $A from i\"file:///c:/myTM.xtm#test\"($A,$B) ?=20
=20
I got always the same error: TopicMapRuntimeException->Cannot find topic
with subject indiciator..

[TM4J-users] Some ideas for *cross* TM navigation with TM Nav

[<vt...@ne...>]

Hello,

Fist of all, I've just download the latest version of TM Nav : Whaooooo =21=
 =

Real improvement against the 0.2.5 one : I'm really impress by the new =22=
abstracting=22 and =22rendering=22 features, which are really very useful.

I mail you to know if you plan to include some *cross* TM navigation featu=
res in complement to the  *direct* TM navigation feature you've implemente=
d in the latest release ...

I mean : =

	by *direct* TM navigation : navigation allowing you to know *everything* =
about *a unique topic* (id, all name(s), all PSI(s), all occurrence(s) and=
 all r=F4le(s) player, ...)
	by *cross* TM navigation : navigation allowing you to know *only few thin=
gs*, but about *all the topics of one given topic type* (some name, some o=
ccurrence(s) and some r=F4le(s) player), ...)


Imagine something which allow you to define sorts of extraction =22pattern=
s=22 :

One =22pattern=22 define :
	- 1 : a given topic type to begin the =22cross TM navigation=22
	- 2 : the occurrence you want to see via the definition of =22given occur=
rence types =5Bof the given topic type=5D)
 	- 3 : the topics you want to see via the definition of =22given role typ=
es involved in a given association type where the given topic play a given=
 role type=22
	- and for each topic define again point 2 and point 3
	- and so on ...

For example : I want to =22extract=22 : =

	- all topics of the *people* topic type =

	- with *e-mail* =22occurrence type=22 =

	- with *telephon* =22occurrence type=22 =

	- ... And perhaps other kind of =22occurrence type=22 =

	- and all the topic of =22company type=22 playing the role of =22employer=
=22 in a *employ* =22association type=22 where the given people play a *em=
ploye* =22role type=22
		- with *home page* occurrence type=22 =

		- ... And perhaps other kind of =22occurrence type=22 =

			- and for each *company* : all the topic of =22company type=22 playing =
the role of =22partner=22 ...
			- and for each *company* : all the topic of =22company type=22 playing =
the role of =22subsidiary=22 ...
	- ...

 The idea is to be able to use patterns to navigate TMs (with sort pr=E9-d=
efine differents perspectives) ... For one given topic type you have one o=
r more pattern defined, if there is only one pattern you take this pattern=
 otherwise you give the choice to the user (by contextual menu for exemple=
) ... And when the =22view=22 is extract you can apply to the extracted =22=
output=22 topics the available pattern(s) according to them type by the sa=
me processus I describe for the =22input=22 topic type ...

A pattern should be valid for a set of TMs conform to a given ontology.
I think if the topic map is driven by a ontology it is more powerful, beca=
use topic type are declare =22by intention=22 in the ontology and not =22b=
y extention=22 in the KB ... And in this case you can associate a set of =22=
pattern=22 to a given ontology and use it for each map conform to this ont=
ology ... But it's not mandatory to have the feature I describe above

Hope I was clear in my explanations

Regards and thank a lot for such wonderful tool

Bernard

Re: [TM4J-users] TM4Web/Velocity 0.2rc1 supports Hibernate backends?

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

Hi Mathias,

I tracked down the error in the TM4Web/Velocity source. I've checked a
fix for this into CVS - so it will be part of the 0.2 release.

If you are happy to grab the file from CVS and build it yourself thats
cool. If you would like a compiled version of the JAR file, email me
privately and I'll send it to you.

Cheers and thanks for the bug report!

Re: [TM4J-users] TM4Web/Velocity 0.2rc1 supports Hibernate backends?

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

Hi Mathias,

TM4Web/Velocity does support the Hibernate backend, but the <topicmaps>
element is only provided for loading topic maps from a file-system
directory (so its only used with the in-memory backend). You have to
configure each topic map you want displayed separately. It would
probably be nice if there was an option to list either all of the topic
maps in the database or some subset (e.g. by matching the baseLocator
against a regular expression). I'll look into adding something like that
for 0.3.

Cheers,

Kal

[TM4J-users] TM4Web/Velocity 0.2rc1 supports Hibernate backends?

[Mathias R. <mat...@we...>]

Hello,

I'm stuck with setting up TM4Web/Velocity 0.2rc1 with a hibernate
backend.
Configuration is
  <provider name="hibernate" 
factory="org.tm4j.topicmap.hibernate.TopicMapProviderFactoryImpl">
    <provider-properties>
      <property name="hibernate.connection.url" 
value="jdbc:mysql://localhost/tm4mail"/>
      <property name="hibernate.connection.username" value="***"/>
      <property name="hibernate.connection.password" value="***"/>
      <property name="hibernate.dialect" 
value="net.sf.hibernate.dialect.MySQLDialect"/>
      <property name="hibernate.connection.driver_class" 
value="com.mysql.jdbc.Driver"/>
    </provider-properties>   
  </provider>

I don't get any errors but I don't get any TopicMaps from by backend 
either. In stdout.log it says
"topicmaps element ignored for provider 'hibernate' which is not in-memory."

Do I miss something or is Hibernate support currently not available with 
TM4Web/Velocity?

Thanks,
Mathias

[TM4J-users] Re: Problems parsing tolog queries

[Bret C. <bre...@ya...>]

Kal,

A belated "thank you" for your help getting queries to
parse using source locators. I have used your help to
get it working.

FYI, I've also attached my own analysis of how I made
the mistakes I did & how the documentation might be
improved so that people like me (if there are any :>)
don't make the same mistakes. (It's probably more
information than would be helpful, so you might just
skip to part B. Suggestion: Table Describing Different
Types of Locator.)
