Re: [Bodington-developers] tetra & IMS TI

[Jon M. <jo...@te...>]

IMS are certainly sticking to their house style. From an initial scan 
through the impression that while the authors have attempted to address 
a very general concept of "tool" they have set all sorts of arbitrary 
constraints on what a tool can do. The vaguest part of the document is 
the bit that I think is most important - authentication and 
authorisation. It looks like the system that hosts the tool has to be 
very highly trusted by the system that hosts the LMS (and vice versa). I 
think the scenario they have in mind is two systems running on servers 
that share the same machine room rack, each with commercial software 
installed from two different vendors.

I feel that a better way to progress would be for a variety of teams of 
software developers to try out their own practical solutions to the 
problem and apply a year or two of natural selection to shake down the 
best approach. Then is the time to formalise the whole thing in a 
logical and well written spec. which is aimed at an audience of tool 
developers. But, I don't really think any of this stuff is really 
specific to LMS/VLE systems - it is a much less specific problem which 
relates to any kind of web based service that is used by people assuming 
a variety of roles and interacting with each other in complex patterns 
while accessing and creating data, some of which is private to an 
individual or group and some of which is public.
