Re: [TM4J-users] Is it a problem to merge topics and topic-types separately?

Hi Ketil,

The problem is the references in your Topics.xtm. When you have a 
<topicRef xlink:href="#books"/> element, the reference is to a topic 
with the URL <path>/Topics.xtm#books. When you merge in topicTypes.xtm, 
the <topic id="books"> element has the source locator 
<path>/topicTypes.xtm#books.

I see that you have some relative URIs in topicTypes.xtm for subject 
identifiers. What I advise you to do is to:
1) Convert those relative URIs to absolute URIs with a full domain name 
e.g. http://www.online.no/psi/types/books
2) Either
  2a) Replace the topicRefs in Topics.xtm with subjectIndicatorRefs 
using the full URIs OR
  2b) Create "stub" topics for your topic types in topics.xtm that only 
have the id and the full subject identifier e.g.
  <topic id="books">
    <subjectIdentity><subjectIndicatorRef 
xlink:href="http://www.online.no/psi/types/books"/></subjectIdentity>
  </topic>

If you do (2a) you are basically replacing a reference to a topic with a 
reference to a subject identifier, that will get resolved during 
merging. Actually what happens "behind the scenes" is that a stub topic 
gets autogenerated for you.
If you do (2b) then you can carry on using the shorter topic refs in 
your topics.xtm because the topics.xtm#books topic will get merged with 
the topicTypes.xtm#books topic by their subject identifier.

(2b) could result in a smaller Topics.xtm file if you have lots of 
references, but I think that is really the only difference between the 
two approaches.

Hope this helps,

Kal
