[TM4J-users] Extract themes using scopes

[fabien b. <fab...@gm...>]

Hello,

I'm currently in study in a french university
and i have to develop a tool with java and the API TM4j
to purpose a view of informations contained in a Topic Map.
The tool may realize an informations view in a theme way.
So i think i have to use scope but i don't know the way to extract all
scopes
from a topic map...  I post here hopping to get a little algorithme
to just extract scopes, or to get some informations about scopes.

Please i need some help

Re: [TM4J-users] Sorting in Tolog

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

Hi Dandan,

The default sorting algorithm is not exactly clever - if you sort a 
variable that binds to TopicMapObjects (like $TYPE binds to Topics in 
your query), then the sort order is by the ID property of the topics.

Are you seeing the results at least grouped together by type (even if 
the types are not necessarily in the order you expect) ? Or are you 
seeing them all mixed up ?

Cheers

Agreed the security could be made tighter. I think that the goal of this=20
document is about how to get something up and running in a development=20
environment rather than how to get a live deployment running. To be=20
honest, I still think of the Hibernate backend as a development=20
environment as it has so many flaws (like not supporting tolog querying=20
and being s-l-o-o-o-w).

I would be happy to see someone write a proper installation guide for=20
TM4J/Hibernate/MySQL (I guess that MySQL would be the most commonly used=20
database), but preferably in Docbook format so that it could go into the=20
  rest of the "standard" docs.

Notes:
a) The code tests if both topics are role _players_ in the same
   association and does not take care about the role type.
b) Using a java.util.List instead of a Set might be faster. The
   duplicates (if any, since that means a topic plays more than one
   role in the same association) are acceptable

[TM4J-users] Sorting in Tolog

Hi All,

I am working on the Tolog Query implementation. My problem is,
the returned tolog resultsets  can not be sorted , even if I use the =
"order by" clause.
for example:
query =3D "select $TYPE, $VALUE from occurrence(topicID, =
$OCC),type($OCC, $TYPE), value($OCC, $VALUE) order by $TYPE ?";=20
=20
for this query, the returned tologResultSets showing in  a JTable will =
not be ordered by ascending $TYPE.
=20
I also did some similar experiments in the  TMNav, seems it has the same =
problem.

One possibility:

    boolean result = false;

    Set<Association> assocs = new HashSet<Association>();

    // First collect the associations where Topic t1
    // plays a role
    for (Iterator iter = t1.getRolesPlayed().iterator(); iter.hasNext();) {
        AssociationRole role = (AssociationRole) iter.next();
        assocs.add(role.getAssociation());
    }

    // Then find out if t2 is part in one of the collected
    // associations.
    for (Iterator iter t2.getRolesPlayed().iterator(); iter.hasNext();) {

        AssociationRole role = (AssociationRole) iter.next();
        result = assocs.contains(role.getAssociation());
        if (result) {
           break;
        }
    }
    return result;
         
  }

The TMAPI code would look like:

    // Assuming that "tm" is your org.tmapi.core.TopicMap instance

    // Topic that should be used as type for the occurrence
    Topic descr = tm.createTopic();

    // Creates a topic name with the value "description" in the
    // unconstrained scope
    descr.createTopicName("description", null);

    // The topic "t" is the topic that should contain the occurrence
    Topic t = tm.createTopic();

    // Create the occurrence with type "descr" in the unconstrained
    // scope
    Occurrence occ = t.createOccurrence("chapter1", descr, null);

[...]

The TMAPI indexes are for lookup operations only. You cannot modify
the topic map instance with the indexes.

Which API are you using?

If you're using the native TM4J API, you can use the objects and their
methods here:
http://tm4j.org/tm4j/docs/apiDocs/org/tm4j/topicmap/package-summary.html

If you're using TMAPI you can use the objects / methods documented
here:
http://tmapi.org/apiDocs/index.html

If you provide an use case I'll give you an example.

[TM4J-users] Hibernate and Locators

[Thomas M. <th...@sn...>]

Hi,

I want to look up all topics that have a certain subject indicator. While
this works without problems with the in-memory backend, there seems to be no
elegant solution for the Hibernate backend:

// using Hibernate provider...
LocatorFactory lf         = provider.getLocatorFactory();
Locator        psiSynonym = lf.createLocator( "URI", PSI_SYNONYM );
TopicMap       tm;
// ...
Collection c = tm.getUtils().getMembersOfType( topic, psiSynonym );

The last line causes a ClassCastException with the Hibernate backend...
because the Hibernate implementation of getMembersOfType() uses a cast to
URILocatorImpl on the Locator object:

  LocatorDataObject ldo = (LocatorDataObject) sess.load(
                          LocatorDataObject.class,
          ====>           ((URILocatorImpl) subjectOrIndicator)
                          .getPersistenceId());

But createLocator() returns instances of TransientURILocatorImpl, so this
cannot work.

I've found a workaround by using an implementation specific call to create
suitable Locator instances:

if (lf instanceof org.tm4j.topicmap.hibernate.LocatorFactoryImpl) {
  psiSynonym = ((org.tm4j.topicmap.hibernate.LocatorFactoryImpl)lf)
               .createPersistentLocator( "URI", PSI_SYNONYM );
}
else {
  psiSynonym = lf.createLocator( "URI", PSI_SYNONYM );
}

This works (and TM4J uses the same "trick" in its
getSubClasses/getSuperClasses methods), but it does not seem elegant to me
(it relies on the implementation instead of a public interface).

Is there a better solution that uses only public API and does not depend on
a certain implementation?

bye, Thomas

Note: The "#" at the end is missing.

Should be:
  static final String TM_LANG = \\
                     "http://www.topicmaps.org/xtm/1.0/language.xtm#";

Best regards,

How about:
 static final String TM_LANG =3D
                     "http://www.topicmaps.org/xtm/1.0/language.xtm"

 Locale locale =3D Locale.getDefault();

 // Note that the ISO 639 is not stable
 String preferredLang =3D locale.getLanguage().equals("de") ? "de"
                                                          : "en";

 // Used to create the subject identifier
 String langReference =3D TM_LANG + preferredLang;

 // Subject identifier
 Locator langLocator =3D topicMap.getBaseLocator().resolveRelative(loc);

 // Fetch topic by the subject identifier
 Topic langTopic =3D topicMap.getTopicBySubjectIndicator(langLoc);

 if (langTopic =3D=3D null) {
    langTopic =3D topicMap.createTopic();
    langTopic.addSubjectIndicator(langLocator);
 }

 nameExtractor.addPreferredTheme(langTopic);
=20

Hi,

Code was wrong, here a slightly modified version.

---
 // Put this in one line
 static final String TM_LANG = \\
                     "http://www.topicmaps.org/xtm/1.0/language.xtm";

 Locale locale = Locale.getDefault();

 // Note that the ISO 639 is not stable
 String preferredLang = locale.getLanguage().equals("de") ? "de"
                                                          : "en";

 // Used to create the subject identifier
 String langRef = TM_LANG + preferredLang;

 // Subject identifier
 Locator langLoc = topicMap.getBaseLocator().resolveRelative(langRef);

 // Fetch topic by the subject identifier
 Topic langTopic = topicMap.getTopicBySubjectIndicator(langLoc);

 if (langTopic == null) {
    langTopic = topicMap.createTopic();
    langTopic.addSubjectIndicator(langLoc);
 }

 nameExtractor.addPreferredTheme(langTopic);

Best regards,
Lars

Re: [TM4J-users] Problems using a rule from an added module

Hi Carolina,

I think you've discovered another tolog parser bug.

Maybe it works if you use a double colon "::" between the "ned"
namespace and the predicate name?

Did you try to import the "Functions.tl" module via the "import"
directive, too?

Does the following work:

static String "import \"file://Functions.tl\" as ned\n" +
       "ned::Reglas-del-Producto(i\"file:ned.xtm#packseguridadtotal\",$Reglas)?"

Hi Lars,=20

First of all, thank you for your answer.=20

I've been trying your suggestions and I step to comment my results:

[...]
> Maybe it works if you use a double colon "::" between the "ned"
>namespace and the predicate name?
[...]

I tried this one first and it works!! :). It seems that when parsing =
tolog queries, colons are eliminated -or something like that-, could it =
be? As I can read, the tolog 1.0 specification establishes that this =
query has to be written with a single colon. If this is a bug, do I have =
to report it?=20

On the other hand, when I tried to use the "import" directive -as you =
told me- I got an exception (posted below), similar to the exception =
obtained when I tried to use de "using" directive.

Thanks a lot again,
Carolina Anton

The exception:
