From 25/9/2003 Teleconf:

Jeff: we want to produce a WS-Security roadmap-like document; we need a roadmap that groups services, and defines how 
they ought to be defined.

David: Hierarchy (not taxonomy) gives this buildout.

Shel: we are in a context of many Web services organizations, we need to define things that belong here and that we 
leave to others. 

David: in the [OGSA] document we define the architecture, then look for the pieces (and see where they should
come from). 

Shel: need to make this clearer in the document.

Shel: factoring depends on how things are done outside. 

Jeff: agreed, some of the parts are going to come from elsewhere. The roadmap is doing this dependency analysis and what
 services come first. We might need to focus on
this later.

David: taxonomy can be done in an abstract way. The hierarchy can't. We might run in conflicts there.

Hiro: Not fully resolved yet, but a lot of consensus on this issue. We take the direction presented by Jeff.  .
