RE: [wsdm] What comes first: The Sandwich Approach to Development

I agree that designing a solution for mgmt. of web services is an end 
goal that this TC should focus on.  However, I don't see how we can do a 
good job of that without considering how this information is retrieved, 
accessed, and exposed and how what we have modeled is implemented.  If I 
can make an analogy, it is like saying that we want to build a 5 story 
building with all sorts of features and we will worry about the material 
we use to build this building later!  Unfortunately, many features that 
we may want to build into this house won't be supported by the intrinsic 
behaviors and capabilities of some materials and no matter how nice the 
house looks in our mind, its construction will fail because we have not 
considered the features of the materials and the infrastructure that we 
may likely use to build this house.  [ BTW: If you ask any good building 
constructor, they will give you the same argument :)  There is also a 
great story about a large auto company that tried to build a 
revolutionary car without considering the material that should be used 
to build it.  The project was a big failure... I can send it separtely 
to whoever that is interested].  We are also likely to over engineer 
somethings if we don't take some features of the building blocks and the 
infrastructure into account and create an unnecessarily heavy weight 
solution in addition to introducing other types of problems (e.g. lack 
of flexibility, scalability, etc.)  So, I strongly believe that we will 
not be able to create a successful solution if we do one (mgmt. of) 
without having an eye on the other (mgmt. through).

I also like to caution everyone to not jump on any bandwagons without 
considering the requirements of what we need to accomplish.   We should 
certainly consider work that is done and being done elsewhere (e.g. W3C, 
DMTF, GGF, etc.) but having wrapped our minds around them is very 
pre-mature before we even look at their pros and cons in the context of 
this TC and whether they even meet our needs.
