[MOBY-l] Class ontology question

[Rebecca Ernst]

Hi Mark!

I had some discussions on the class ontology with my colleague Dirk and 
we didn't come up with a solution to our problem so I hope you have an 
answer to it ;-)

I read your DesignAnObject page and found out that my Virtual Sequence 
object is not correct in that terms.

It looks like this:

<GenericSequence ns='' id=''>
<Integer ns='' id='' articleName='Length'> </Integer>
<String ns='' id='' articeleName='Description'>blabla</String>
<String ns='' id='' articeleName='SequenceString'>atgtaag...</String>
</Generic Sequence>


If I get it right GenericSequence HASA String. this means that it 
contains exactly ONE instance of String. But my object contains TWO 
instances of String.

If the relationship of GenericSequence would be HAS instead of HASA it 
would be 'legal' I suppose.

What would be the correct way to Design the object? Should I have 
another object
CommentedSequence ISA GenericSequence HASA String
OR
CommentedSequence ISA Virtural Sequence HAS String
???

What's the purpose of having two similar relationships (HASA and HAS)?

Thanks in advance
Rebecca
