[TM4J-users] Resending: Re: Bug Report + Possibility of Writing a new "Tolog Abstractor"

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

Yesterday, I sent Christoph & tm4j-users some
messages, but went over the list's space limitation.
I'm resending the messages as attachments. I think
they should stay within the space limitation this
time.

Your TologQuery looks for a sourceLocator ("element1"), but
createTopic(String) just assigns an id.

replace the line
                topicmap.createTopic("element1");

with the following

                Topic t = topicmap.createTopic("element1");
                Locator base = topicmap.getBaseLocator();
                Locator loc_e1 = base.resolveRelative("#element1");
                t.addSourceLocator(loc_e1);

this works at least for me.

Ohhh. You got me. I've never filed one. 
But I guess you should point your browser to

In the last time I came to the conclusion that all abstractors
essentially work in two steps.
1. They get the data, typically by using Extractors or in our particular
case by executing a tolog query.
2. They build the Model from that data. I started to call this step the
'molding'. I've found that word in german-english dicitionary and I
liked it, but meanwhile it sounds a bit strange to me. Is it a common
word?

Nevertheless. What we need to do is to make the 'molding' step of the
TologAbstractor customizable. Then we can create models of any shape we
can think of.

I agree totally that there are plenty of ways to present a particular
resultset in a meaningful way. My concern was about finding another
_generic_ form of presentation. For generic purposes a table is pretty
good I think.


But maybe we can start with a simple use case. For example with
resultsets that have only one column and that store TopicMapObjects and
not Integers in that column.

We could then say, that we use the CompactAbstractor to transform the
TopicMapObject of each row into a model and that we add all the
centernodes of all the models to a sort of supermodel that will be
returned. The centernode of that supermodel will be of a new Gestalt,
GESTALT_INVISIBLE and the abstractors could be updated to recognize that
Gestalt and to not to draw it.

Does this sound like what you was thinking of?

[TM4J-users] Re: Bug Report + Possibility of Writing a new "Tolog Abstractor"

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

Hi Christoph

Thanks for your taking the time to think this through.

Some points:

1. What's the procedure for filing a Bug Report with
Kal about the issue I raise?

2.My reasoning about the possibility of writing a
Tolog Abstractor for a Hypergraph is as follows:

True Tolog returns results as rows & columns, but that
doesn't mean they can't be used for other purposes. 

We know that the following two sequences are possible:

Tolog query => Topic Map Fragment (really just another
topic map - right?)

Topic Map => Compact Abstractor => Hypergraph Renderer

So, if worse comes to worse, I could simply write an
abstractor that takes as input the Topic Map Fragment,
rather than the raw Tolog results - Or is there some
intermediate state from which to draw?

Anyway, isn't a row just a way of referring to a set
of values for the attributes of an object, with each
column containing the values for a particular type of
attribute?

Well, I have to go, but I'll continue to think, and
I'll be sending a better specification for what I need
shortly.

I agree totally with you, that the model that the TologAbstractor
currently generates is not suitable to be presented by any of the
generic renderers (Touchgraph-, Hypergraph or TreeRenderer). 

I've remarked that the TologFrame allows you to choose a renderer and,
at this time, I would consider this as a bug, since using any other
renderer than the TableRenderer does not produce useable results. 

Nevertheless, introducing switches in TologAbstractor that specify the
shape of the generated model is easy from a technical point of view. And
it would be great to implement it. But unfortunatley I fail to imagine
how this models should look like. 

Basically, a TologQuery returns a result set. Which means: tabular data.
Rows and columns and 
each cell of a row is related to all other cells of that row and 
each cell of a row is not related to any cell of all other rows. 

How this could be transformed into an intuitive graph view is currently
not comprehensible to me (which should not mean, that it is impossible,
but I fail to see it).

>From the reading of your notes, I think you have some more concrete and
more specific intentions. Maybe you can tell us more about the goals of
your  project and what you would like to see as the result of specific
queries. 

I'm really interested to learn what users of tmnav would like to see. I
guess, beyond a certain point it will always be necessary to define
custom abstractors. 

It would be great to define a construction kit, that allows the
generation of custom abstractors for non-coders (endusers!).
If you could provide us with a more concrete description of how you
expect the result of a distinct query being presented, we will
eventually get ahead towards a toolbox for generating custom
abstractors.


Thanks again for your input

Hi, Tobias,

when you download the source distribution, or check out the project from  
cvs, you should find the build.xml file in question in the root folder of  
the project. Invoking Ant from this folder with the ozone-install  
parameter should do the trick;

c:\projects\tm4j>ant ozone-install

Hope this helps you along.

[TM4J-users] setup ozone backend?

[Tobias H. <tob...@me...>]

ladies, gentlemen,

I am trying to setup the ozone backend for tm4j, and try to follow the
instructions by kal, found in Appendix B. Installing The Ozone Back-End.

I am no programmer, and maybe it is because of that that i completely
fail to make sense from the following:

> [...]To create a new database simply invoke ant with the target
> 'ozone-install'. This target accepts three parameters as described
> below.[...]

I have ant installed, paths and home set, and typing "ant" gives me (on 
a win2k system with a rather current jsdk)

Buildfile: build.xml does not exist!
Build failed

ok so far. but how would i invoke ant with the target 'ozone-install'? 
do i have to create my own build.xml, or is there a commandline-version 
to do that?
http://www.iseran.com/Java/ant/tutorial/ant_tutorial.html and 
http://www.cs.huji.ac.il/~dbi/ant-manual/ did not do the trick for me...

I guess it is obvious, for those who know it - any hints, please? :)

[TM4J-users] tolog query testing results for TM4J 0.9.6 & TMNav 0.2.8 attached

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

Christoph,

I did some testing of tologx in TM4J 0.9.6 & TMNav
0.2.8. I've attached the results
(TologTestResults.txt).

For TMNav, I tested variations of a Tolog query passed
to the Tolog Abstractor and then represented by
various renderers.

One problem for both applications is that queries
don't seem to work when they are forced to iterate
over more than one type of association.

Another problem, specific to TMNav, is that the
Hypergraph & Touchgraph Renders don't seem to bind the
variables (such as $ASSOCIATION & $ROLE) to their
values - Each are displayed separately. And the Table
Renderer even fails to show the values.

Even if you succeed in fixing these problems, I think
I will have to write my own abstractor, because I need
to display results in a Hypergraph or Touchgraph,
and I don't find the way the Tolog Abstractor's
table-oriented model are displayed by those renderers
to be intuitive. FYI, I've enclosed a discussion of
this issue, together with some ideas of mine about
what to do about it (AbstractorReqs.txt). If you can
either make use of these ideas for your own work or
comment on them for me, they will have served their
purpose -- though, of course, don't feel obligated to
do either.

Christoph,

I tried copying the configuration files, and that
works.

(I see there is no longer a panel for entering tolog
queries - a slight inconvenience for purposes of
testing, but I probably won't be using such a panel in
my app. anyway.)

Re: [TM4J-users] TMNav-0.2.8 fails to start - creates blank config files

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

Hi Bret

this is bad !! Sorry for this.
Good is, that I was able to reproduce. I 'll try to check in an updated
version soon.


If you don't want wait, I see two options:

Either download the binary version. It seems, at first glance, that the
bug only occurs with the src-distribution.

Or copy manually the files TMNAV_HOME/src/org/tm4j/tmnav/app/*.xml
(should be three files: tmnav.xml, panckouckecontext.xml and
tmnav-defaults.xml) to the .tmnav-directory which is located in your
user-directory. Then restart tmnav. This worked for me. The bug seems to
be located in the copy-routine, so if you do the work manually, tmnav
should start.

Sorry again for the inconvienience, Bret.

Bye
c

[TM4J-users] TMNav-0.2.8 fails to start - creates blank config files

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

Hi Christoph,

I tried tmnav-0.2.8-src on my Windows XP notebook.
When I ran the runtmnav.bat, TMNav failed to start.
After a few tries I got a message that pointed me to
the configuration files in the .tmnav directory
(tmnav.xml, tmnav-defaults.xml, panckouckecontext.xml)
All three files were created as empty files. Upon
repeating the process, I got the same results.

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

Thanks so much Christoph (particularly if yesterday's
release of tmnav 0.2.8 was for my sake). I'll try tm4j
0.9.6 & tmnav 0.2.8 (The progress on your end is
outpacing my own progress!). I'll let you know how
tmnav 0.2.8 is functioning for me.

Hi Christoph,

Thanks very much for that, it now works fine. Sometimes, you just look at something too hard and
can't see the obvious mistakes.

Thanks again.

Re: [TM4J-users] topicMapProviderException

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

Hi richard

you need to remove the line
TopicMap yeast_tm = tm_provider.createTopicMap(tmLoc);

This line creates an empty topicmap with base locator tmLoc.

And the following call to
 new SerializedTopicMapSource(insTM, tmLoc);
tries to create another map with the same baselocator.
This triggers the exception.

Re: [TM4J-users] tologx-query does not find a topic in the topicmap

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

Hi Armin,

thanks for the testapp that really helped to track down the problem. 

Fortunately it was not a bug in tm4j but a simple missing '#' while
creating the Locator.

Instead of:
 Locator lo = tm.getProvider().getLocatorFactory().createLocator(
                        "URI", "testID");

create the Locator relatively:

 Locator lo = tm.getProvider().getLocatorFactory().createLocator(
                        "URI", "#testID");

This works for me.

[TM4J-users] topicMapProviderException

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

Hi All,

I have the section of code below which is attempting create a new in memory topic map provider,
and to open a topic map held in a file system and add it to the provider so that I can make some
additions to it.

Properties myProperties = System.getProperties();
myProperties.put("tm4j.name.based.merge","false");
	    	
TopicMapProviderFactory providerFactory = new
org.tm4j.topicmap.memory.TopicMapProviderFactoryImpl();
tm_provider = providerFactory.newTopicMapProvider(myProperties);	
			
//Open the existing function topic map
File inputFile = new File("funcat_tm_from_db.xtm");
FileInputStream insTM = new FileInputStream(inputFile);
Locator tmLoc = tm_provider.getLocatorFactory().createLocator("URI",
"/home/richard/Documents/topicmaps/funcat_tm.xtm");
TopicMap yeast_tm = tm_provider.createTopicMap(tmLoc);
			
System.out.println("TM baseLocator established");
			
TopicMapSource tmSource = new SerializedTopicMapSource(insTM, tmLoc);
			
System.out.println("Adding topic map to provider");
						
TopicMap myTopicMap = tm_provider.addTopicMap(tmSource);
			
System.out.println("TM added\n");	

The problem i have is that I'm getting the following topicMapProviderException, saying a topic
with this base locator already exists, and I can't figure out why. Here is my console output:

TM baseLocator established
Adding topic map to provider
Exception caught: Provider already contains a topic map with base locator:
/home/richard/Documents/topicmaps/funcat_tm.xtm
Provider already contains a topic map with base locator:
/home/richard/Documents/topicmaps/funcat_tm.xtm
	at org.tm4j.topicmap.memory.TopicMapProviderImpl.createTopicMap(TopicMapProviderImpl.java:293)
	at org.tm4j.topicmap.source.TopicMapSourceSupport.addTopicMap(TopicMapSourceSupport.java:67)
	at mips.genre.topicmaps.CreateGenomeFuncTopicMap.run(CreateGenomeFuncTopicMap.java:94)
	at mips.genre.topicmaps.CreateGenomeFuncTopicMap.main(CreateGenomeFuncTopicMap.java:45)

I'm sure it must be something I'm doing wrong, but I can't figure out what. If anyone could shed
some light on this I'd be grateful.

Thanks.

Richard.

Re: [TM4J-users] Tolog Panel Problems (TMNav) (+Tolog, TMNav, TM4J version question)

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

Hi Bret

Some of the issues you are describing should be fixed in TMNav-0.2.8,
but others might not.

The Tolog-integration of tmnav is rather a hack, but I would like to
improve it. If your time allows to give me feedback about the behavior
of 0.2.8, this would be most appreciated.

Sounds like a good idea to me. I will check it when looking into Armins
testproject.

Tolog1.0 was introduced since tm4j 0.9.5. It is implemented in a new
package called tologx, while the old implementation is still available
in the tolog-package. 

TMNav supports Tolog1.0 since 0.2.8 which I did release yesterday.
Please give it a try.
