Hello Together,
my name is martin and i'm new on the list.
I have a question concerning tolog. The following query should turn back
all childs of T.
TologResultsSet trs = qe.execute("child-of($Child:child, T) ?");
Well it returns all child topics but it returns the parent topic as well,
leading to some nasty effects.
In $Child I only want to have the childs and not the elmeent itself.
what's wrong with this query?
thanks
martin

Hello again
Eventually, the only solution I found, in order to remove an AssociationR=
ole
from
Association, is the following:
1. I replicate the previous association with a new one (without the
specified AssociationRole)
2. I move the Reifier into the new association
3. I remove the old association completely
If anybody has some ideas on this problem, or would like to ask for
something, I would like to read it
Cheers
George

Hello again,
(I am attaching this as a plain text also, for easier reading)
I have a problem with Associations and after some days of confusion I found
out that:
In my hibernate/MySQL server (I have a client server application using RMI)
The server is trying to delete an AssociationRole, because of a clients RMI
call
here is my code (in the server):
Association a = m_associationRole.getAssociation ();
m_associationRole.remove ();
System.out.println ("comes up to this point");
Set<AssociationRole> set = a.getAssociationRoles ();
System.out.println ("never comes here!");
This generaly should work OK but:
If for some reason a previous (different) RMI call from the client (or
another client), used this specific Association that holds the
AssociationRole
As a result, I have the following Exception:
comes up to this point
org.tm4j.topicmap.ProviderTransactionException: Error updating data object.

I need to restart the server in order for the Association to work OK.
(I have no similar problems with Topics, or deleting the full Association,
or Occurrences)
I am not a hibernate expert and I don't know if someone that knows hibernate
could have any ideas on this
It seems to me there is a problem with sessions or something like this
any ideas?
Cheers
George

Hi George, It sounds like the association role has lost its reference to its association in the database. There is no easy fix for this = programmatically. I think you might have to look in the database tables to try and figure = out what can be deleted.=20 However, what would be important would be to find out how the reference = got lost. E.g. can you tell what association it should be in, and can you = see if that association still exists. Or perhaps you called = association.remove() and the code did not remove the association roles (in which case perhaps there are other association roles with no parent association in your = topic map).

Hello
I have the following Tolog problem
(I am using TM4J-0.9.8 with hibernate)
when I pass the :
select $T, $VAL from topic($T),
occurrence($T,$OCCURRENCE),
type($OCCURRENCE, tel),
value($OCCURRENCE, $VAL)?
I get the correct result,
but the query:
select $T from topic($T),
occurrence($T,$OCCURRENCE),
type($OCCURRENCE, tel),
value($OCCURRENCE, "123")?
throws the following exception:

Hi George,
I think that it is exactly the problem that you suspect. When the
transaction is closed, the results set is also closed. What you will
need to do is to wrap your use of the tolog results in its own
transaction. So you will need a few extra calls in your sample code:

What *should* happen is that the underlying Hibernate topic map provider
code should use the transaction you explictly opened for all lookup
operations involved in processing the tolog query and it should not try
and close the transaction (because it did not open it).
I guess this is really a workaround for an underlying problem which is
that the Tolog query implementation is not doing the transaction
wrapping itself. Although the real issue at the heart of this is that
the tolog implementation for Hibernate should be making more use of SQL
or Hibernate's query language instead of translating the query into
operations against the TM4J API. Neither of those changes are going to
happen quickly to the code base (unless someone wants to volunteer!), so
in the meantime I recommend that you do this explicit wrapping in your
code. In a way it is clearer anyway - even if it does require a bit more
typing!
Hope this helps**,
Kal
** Disclaimer - I haven't actually tried this, but it is my best guess,
and its the way that I worked around other issues with iterators
returned by the Hibernate implementation.

Hello Kal (and Hibernate users)
it's me again :-)
because the mail breaks the lines and the message is not very easily
readable, I am attaching it as plain text also
I don't want to bother you, but I don't know what to do here
I thing the CLASSPATH and the .jar files are all OK.
(the jars are from "tm4j-bin-0.9.8.zip")
When I call the following code:
Properties props = new Properties ();
props.setProperty
("hibernate.dialect","net.sf.hibernate.dialect.MySQLDialect");
props.setProperty
("hibernate.connection.driver_class","com.mysql.jdbc.Driver");
props.setProperty ("hibernate.connection.url","jdbc:mysql://localhost/etm");
props.setProperty ("hibernate.connection.username", "root");
props.setProperty ("hibernate.connection.password", "123");
TopicMapProviderFactory tmpf = new TopicMapProviderFactoryImpl();
TopicMapProvider provider = tmpf.newTopicMapProvider(props);
Map mapFeatures = new HashMap ();
TMAPITopicMapSystemImpl tmApiSystImpl = new TMAPITopicMapSystemImpl
(tmpf.getClass().getName(), props, mapFeatures);
Locator loc = provider.getLocatorFactory().createLocator ("URI", tmName);
org.tm4j.topicmap.TopicMap tm = provider.getTopicMap (loc);
QueryEvaluator qe = QueryEvaluatorFactory.newQueryEvaluator (tm);
TologResultsSet rSet = qe.execute ("topic($T)?");
I get from the "qe.execute ("topic($T)?")" the following Exception:

the

java:22)"
belongs in "mango.jar"
the
"org.tm4j.tologx.predicates.TopicPredicate.matches(TopicPredicate.java:57)"
is the:
addResultsRow(ret, new Object[] {it.next()});
in the:
public VariableSet matches(List params) throws TologProcessingException {
VariableSet ret = new VariableSet();
initialiseResultsSet(ret);
Object p = params.get(0);
if (p instanceof Variable) {
Iterator it = getTopicMap().getTopicsIterator();
while (it.hasNext()) {
addResultsRow(ret, new Object[] {it.next()});
}
} else if (p instanceof Topic) {
addResultsRow(ret, new Object[] {p});
}
return ret;
}
inside the TopicPredicate.java
I understend that the "it.next()" gets:
"java.sql.SQLException: Oeration not allowed after ResultSet closed"
I suppose the "getTopicMap().getTopicsIterator()" (in the case of
Hibernate) is served by:
"org.tm4j.topicmap.hibernate.TopicMapImpl"
public Iterator getTopicsIterator() {
if (m_provider.isTransactionOpen()) {
return getTopicsIterator(m_provider.getOpenTransaction());
} else {
ProviderTransaction txn = m_provider.openTransaction();
Iterator ret = getTopicsIterator(txn);
txn.rollback();
return ret;
}
}
private Iterator getTopicsIterator(ProviderTransaction txn) {
TopicMapDataObject tdo = (TopicMapDataObject) load(txn);
Iterator rawIt = iterate(txn, "select topic from topic in class
org.tm4j.topicmap.hibernate.TopicDataObject where topic.topicMap = ?",
tdo, Hibernate.entity(TopicMapDataObject.class));
return new TransformingIterator(rawIt, getWrapper());
}
(The Topic Map works and it is editable, only the Tolog is that is not
working)
Is it possible that the "Iterator it = getTopicMap().getTopicsIterator();"
closes the ResultSet (accidentally) and then return the Iterator?
Is anybody uses the combination of Hibernate and Tolog without this problem?
Thank you again
George Tryfon

Hi George,
My first guess would be that perhaps the hibernate2.jar file is not
properly loaded, or has got corrupted somehow. Can you list the JAR
contents using the jar command. If I do that on my local copy I can see
the class listed in there. You might also want to check that there is
not an older or newer version of hibernate on your CLASSPATH that is
getting loaded first.
Cheers,
Kal

Hello Kal
Using tm4j-0.9.8, I try to call the following code
TMAPITopicMapImpl tmapiTmImpl = getTmApiTmImpl ();
QueryEvaluator qe = QueryEvaluatorFactory.newQueryEvaluator
(tmapiTmImpl.getWrapped());
TologResultsSet rSet = qe.execute ("topic($T)?");
while the TopicMap is connected to MySQL using Hibernate
the "qe.execute()" throws the following...

The same code works OK when the TopicMap is connected to Ozone or XTM
I have included all these in my classpath

and the Hibernate works OK except for the part of the Tolog.
Do you have any ideas on what should I do to overcome the
net.sf.hibernate.LazyInitializationException?
Thank you and have a nice Summer

Hi, I like to use something similar to the following to get all topics and basenames where the base name contains a search string (for instance .*eferen.* from a topic map that has topics with basenames that have that substring. Tried the following: Select $A, $B from topic-name($A, $B), value-like($B, .*eferen.*)? That gave me an error "Error instantiating predicate class". Could someone tell me what is wrong with that query? Thanks suseela |

Hi Andreas, saas also has a "presentation layer" on the data-input side, all the GUI windows. Harold, You requested a copy of my modified-TMNav-based application. I'm doing a re-write, which should be done in a few weeks. Would you like to wait until then, or would you like a copy of what I've done up until this point? (Also, the user interface is in Portuguese. I tried an earlier version last month to English & sent off the results to Christoph.)

actually, we (meaning christoph, niko and me) considered to port TMNav int=

in the beginning but started doing a portotype because i wanted to how ho=
w difficult this would be. I never got into more than showing some maps, a=
n index and a Renderer (Touchgraph, there are some problems with hypergrap=
h and the SWT=5FAWT bridge which i never got into solving) - much like the b=
asic structure of TMNav. If you are interested, just tell me :).

Well actually i do not think that this seperation would make much sense fo=
r a GUI app (much more an eclipse based app), however i think that the lay=
ers could be drawn something like:
Presentation Model layer (Displaying the Graphmodels->Touchgraph libraries=
)

Business Model layer (Building graphlike abstractions from the TM ->Pa=
nckouke)
^

Database layer (TopicMap engine)

Andreas, I would say that the "database layer" as you call it, is handled by TM4J, including the indexes and tologx packages that allow data to be extracted from the topic map. The business model layer, if there is one, would be handled by your own classes. In the application I created, which you now have, it is handled by my saas classes. Pankoucke handles a different layer. I think I've referred to that layer as an "abstraction layer", though that may not be the best description. It relies on the TM4J classes, and possibly on your "business model classes", to extract the data from the "database" (really the topic map loaded from either a XTM file or a database), and then builds what is referred to in the Panckoucke documentation as an "abstract model" of nodes and arcs, which is then passed to the renderer (the presentation layer). So I would probably locate Pankcoucke and its layer between the business model layer and the presentation layer. Also, you can develop your own abstractors... Out of time...

Hi Harald, thanks a lot for your answer. I really appreciate it (same goes for Bret´s and everybody else´s help), as i really feel like stepping in the dark a little bit at the moment. Thanks also for your inspiration on the software architecture. Another question, as you mentioned MVC. How do you think Panckoucke works together with this pattern? Could this be right: Model: The abstract model which is generated through Panckoucke View: The specific renderer e.g. Touchgraph Controller: Panckoucke itself (a little bit imprecise) > Are you allowed to tell us what you want to do / what kind of data you > want to display and in which way ? For sure, i want to display the relationships between Software Tools (the files they create), which are used in order to get a certain work done. For example, one first uses Word for writing the concept of a certain problem, the produced Word File is then used as an "input" for a UML drawing diagramm, like Rational Rose for example, this Rational Rose document is then used for "input" for the generation of java files. So this whole process makes up "links" between all of this software tools and i want to display those links and the corresponding software tools as an graph within an eclipse plugin. The information for those links is already within a database, so i just need to transform them into a Topic Map and then feed this Topic Map to Panckouke. One thing that´s bugging me all the time and where i would really appreciate an answer: Do you think it makes sense, to transform the Network Data, that is within the Database at the moment into a Topic Map before i represent it as a Graph? Or do you think it might be more useful to directly produce the input file for a specific graph like Touchgraph for example. My point is, that i need a strong querying possibility for the data. This means a user should be able to query the graph something like this: "Show me all Files which are are linked together, with the creation date of those files being less than two days difference" I don´t know at the moment, whether Tolog can handle such a complex request (given that all of the needed data, like "creation date" is provided). And if Tolog is not capable of not handling it, i would therefore need to query the data on the Database via SQL anyway... hmm... any ideas/thoughts on this? (i know it´s kind of off topic ;-) ) Hmm, Harald do you think it is possible to tell me a little bit more about the TMNav Eclipse plugin? I really don´t know where to start at the moment. What i need is also a tree view of the data... do you think this is possible within Eclipse? I always dreamed about incorporating the Hypergarph into Eclipse, but thought of it as being quite tricky. And i only saw one other application (Metrics on Sourceforge), which implemented the Touchgraph as part of an Eclipse plugin. Sorry for the long answers, and the wide range of topics (and questions ;-) ) i addressed within this e-mail but you´re really the only people i can turn to with my problems as nobody i know has a clue about all of this ;-) greetings and a nice evening to all of you Andreas > > Greeting to all > > Andreas > > > > Cheers > Harald > > P.S.

Hi everybody,
i´m currently in the Design phase of the software, which i want to write
(the software is a plug-in for Eclipse, which is displaying a Topic Map as a
Touchgraph).
I want to use the Pancouke library and the Touchgraph library (similar to
TMNav) for my project.
Now, i am pretty confused about the different abstraction layers of my
programm.
My software should have a typical 3-tier architecture, like this:
Presentation Model layer
^
|
Business Model layer
^
|
Database layer
^
|
Database
Can somebody maybe tell me under what Panckouke, the TM4J library, the XTM
Topic Map and Touchgraph can be filed within such an architecture? And what
the equivalent to the database layer might be?
I´m thinking of something like this:
Presentation Model layer (Displaying the Topic Map->Touchgraph libraries)
^
|
Business Model layer (Filtering the Topic Map->Panckouke)
^
|
Database layer ??????
^
|
Database (XTM File????)
Is this correct? Or is this the complete wrong approach when handling Topic
Maps?
I hope you understand what i am trying to say.
Any answer is highly appreciated, as the architecture of the software is
really crucial to my project.
I am thankful for any thoughts/ideas/statements about this or maybe links on
this topic.
Greeting to all
Andreas

Sorry, for this question, i just found out about the jar files in the /lib directory and included them into my workspace.

Hi Brett, thanks a lot for your answer and pointing me towards the resources on the websites. It would be great if you could send me some of your code and the monograph, i am glad for every example i have. Another question: How did you import the TMNav Source Code into your IDE? I am using eclipse and am trying to import the whole TMNav project. As it relies on Packouke and TM4J im am also importing the source code for those two into the same project. But i get something like 9000 errors, because the imports aren´t working. Can you maybe give me a brief introduction how to import the sources? Is there a JAR File somewhere from TM4J, that i just can add to my project, which contains everything i need, maybe?

Hi Andreas, I am doing somthing similar to what you want to do. The key is to understand the structure of TMNav (installation instructions for which are available at <http://www.folge2.de/topicmaps/tmnav/userdoc/en/install.html>, which allows you to use the Touchgraph renderer (or the similar Hypergraph renderer, which I am using in my application) to display an XTM file INDIRECTLY: To quote the TMNav documentation: "A Renderer never works directly with topicmap data, but always with an intermediate structure, called AbstractModel, which is supplied by a distinct Abstractor. To learn more about Abstraction and how it influences what you are going to see, check the panckoucke-documentation." <http://www.folge2.de/topicmaps/tmnav/userdoc/en/renderers.html> TMNav is built on top of TM4J and the Pankoucke library. The latter (documented at <http://www.folge2.de/topicmaps/panckoucke/userdoc/en/aboutpanckoucke.html>) supplies certain abstractors <http://www.folge2.de/topicmaps/panckoucke/userdoc/en/abstractors.html>, which can be used to add data from a topic map (loaded into memory from an XTM file using TMNav) to the AbstractModel (containing nodes and arcs). The AbstractModel can then be fed to a renderer such as Touchgraph to display these nodes and arcs in its own way. If the AbstractModels supplied by the Panckoucke library don't suite your purposes, you can write your own (as I have). The Panckoucke documentation describes how to do this <http://www.folge2.de/topicmaps/panckoucke/userdoc/en/how-to-write-an-Abstractor.html> The TMNav application, in addition to supplying all of the tools to do what you want, is a sample application (which probably does a lot MORE than you or I need to do). It lets you see XTM files displayed with many types of renderers, and includes a complex configuration structure to control all of this. My approach to this was to replace the windows and controlling class used by TMNav with my own simpler windows and controlling classs. If you would like, I could send you a copy of the monograph I wrote describing how I did this, or some of the code (It was a bit difficult - especially for me, since I'm also a beginner both at programming and at working with open-source software.)

Hi Andreas, Probably the best place to start is with the source code for TMNav which uses touchgraph as its visualisation engine. You will see that TMNav is built on an abstraction layer, panckouke, which can also be found in the TM4J download pages.
