[MOBY] [MOBY-l] Registering new MOBY object

[Mark Wilkinson]

Hi Gabriel,

I think you should perhaps look at a few examples of services, or walk
through one of Ken's tutorials online (click on the "Tutorials and How
To's" link on the moby homepage), to answer many of your questions all
in one shot, since most of the answers you are looking for are explicit
or implicit in these tutorials...

articleName is meaningless for ISA relationships - just leave it blank.

it is used to identify a subcomponent of a complex object. If you look
at a few example objects in the API this will be clear.

<VirtualSequence namespace='foo' id='bar'>
	<Integer namespace='' id='' articleName='Length'>10</Integer>
</VirtualSequence>

again, please look at the examples, and see above.  Everything is an
object, and objects have namespace and id attributes.

none. that is their only function.  There may be a reason to add
additional substructure in the future, but at the moment they are an
empty wrapper around a single object, and help to ensure that Simple and
Collection inputs have ~the same XML structures.
