Hi, <br>
<br>
Indeed, this layer is not ready now, so it will have to be slotted
in when it it ready and as you indicate, it will not perturb any
current schemes in play. It is an *option* that we will be able to
support to allow institutions this additional *flexibility*. I
don't propose swapping out one set of imposed rules for another.
;-).<br>
<br>
Also, there will be a mechanism in place to allow for any tool to
perform this resolution. What level this resolution may be
integrated will vary, but there will certainly be an out-of-band
mechanism offered at a minimum. And for tools that speak HTTP they
get this for free without any coding intervention.<br>

<pre wrap="">Hi Gavin,
Layers of indirection can be added but that takes design and development time and even longer to debug and deploy. Using the file system provides a baseline that all the access tools OPeNDAP, GridFTP etc. can use now.

No debate there, i agree, however, design and development time can
be greatly reduced by writing good and wise code. It does not have
to be a protracted process which seems to be what you are implying.
It has largely already been designed and mostly implemented... it is
missing a key piece which we hope to address shortly. But overall
it is quite cogent and straightforward. Indeed, I have suggested
putting together a group of individuals that want to discuss the
details more deeply.<br>

The middleware you describe could be slotted in when ready at a later stage to replace this baseline approach. If it really followed the contract for the interface, no one on the outside would even notice that you'd made the change <span class="moz-smiley-s3" title=";)"><span>;)</span></span>

Indeed, I could not have said it better. Though the interface is
quite a bit more subtle than one would imagine. You are certainly
correct with all of your statements!! :-).<br>
