[tinyTiM-discuss] tmdm:subject/tmdm:name filtering in CTMWriter

[Hannes N. <h.n...@go...>]

Hi everybody,

testing the CTM-export of Onotoa I realized a bug (or feature) of the
CTM serializer.
The topics, using the PSIs of the standard, like tmcl:topic-type, will
be filtered, so they are not
int the CTM file. These topics only will be filtered, if they only
have one subject identifier and
participate in any association. This works for the topic-types,
because the type-instance association
is hidden by the addTypes method in TMAPI.

However there is a problem if tmdm:subject or tmdm:topic-name is used
in a TMCL constraint. Because they are
explicitly in an association. Long story short, the question is, how
do we solve this problem. There are a few options:

1. Let these topic be in the CTM file, which means having an entry
like: "tmdm:subject ." - definitly not what I prefer.
2. Filter these types ignoring the association in an additional filter method.
3. Always ignore associations where topics of the standards are used.

I would prefer 3. Even if the types are used in an association it is
not necessary to specify them before. CTM creates topics on demand, if
I remember correctly.


What do you think?

regards
Hannes

It's a feature, of course. :)

(2) and (3) are okay for me.

Do you mean with (3) that this is done in the CTMWriter and not in the
preprocessor?

Best regards,

actually I meant both to be in the CTMWriter, where all the other
filtering is done.

I see. Do you implement it (either (2) or (3))?

I will implement (3) tomorrow morning.

Thanks.

I changed a few lines, though:

         // remove tmdm:subject, because filter below doesn't work. tmdm:subject
plays a role, so
         // _omitTopic returns false - we definitly don't want "tmdm:subject ." in
our ctm file, do we?
-        Topic topic = topicMap.createTopicBySubjectIdentifier(TMDM.SUBJECT);
-        if ( (topic!=null) && (topics.contains(topic)) ) {
+        Topic topic = topicMap.getTopicBySubjectIdentifier(TMDM.SUBJECT);
+        if (topic != null) {
             topics.remove(topic);
         }


I don't see a reason to create tmdm:subject if it does not exist in
the topic map. If we create tmdm:subject, the topic will never be
null.
         
Committed in rev. 354.

Best regards,
Lars

Well, actually this line is completely unnecessary because i added
TMDM.SUBJECT to the locators regarding Occurrences. (Because it is
used as occurrence-type.)

I thought I already removed it.. obviously not :(

Hannes
