[protege-discussion] Ontology Maintenance

My advice is not to look at the ontology in isolation of its purpose. Given
any existing ontology, where are the manifestations of the concepts it
contains? Don't forget that an ontology is a specification, so in changing
the ontology, there will be an impact on any system that already committed
to that ontology. There will be tradeoff issues - you might design a more
elegant ontology but end up with systems that can no longer interoperate,
which is very costly.

Subject: [protege-discussion] Ontology Maintenance

Hi Everybody,

  Let me introduce myself, my name is Lintang Yuniar  Banowosari, just call
me Lintang, I come from Gunadarma  University, Depok (close to Jakarta)
Indonesia.  Now, i am doing my study in Phd Program in Information
Technology Program ,Gunadarma   University. My research  interest is
Ontology Maintenance, espcecially with Semantic Similarty approach  in P2P
           But , i still in the very beginning of the research.  Up to now
..i have not  clear understanding of the term  "ontology maintenance"
itself.   Is it a step of ontology development (Just like in SDLC, there is
a  maintenance step of the system development)?
           Is it true if i say that : Maintenance of ontology can use  some
approaches.  The approaches in  general are:  
      .           mapping,  where one ontology mapped to other ontology 
      .           merging,  where two or more ontology joined become an
      .           alignment,  where ontology adjustment caused by change or
adjustment of concept and  knowledge.  ??
           If there is anybody have some SOURCES that contain the
information of  "ontology maintenance" issue,   it would be helpfull for me.
           And if everybody do not mind, please kindly share with me.
       Any help (working examples, personal experience etc) in this regard
will be highly appreciated.
      Thank you for your time, 
      Kindly reply my email
