[Good descriptions of inlining/MPD snipped]

If you want the files to be returned to a submodel state, MPD is better.
BUT - that requires splitting the MPD.

And if you use a ZIP archive, you have to unzip.  Unzipping is generally
more convenient than splitting an MPD, for the user.

I think so too.

But with MPD, a single file on the server can be used both for viewing and
for downloading.

Then there is that.

the browser] ...

If you know how to set your browser, you can use LDraw to view from the
web.

Oops.  Quite right.

I think that for an archive of models it is important to remember that, in
order for a user to easily build a model, the model should have subparts.
Trying to build a complex model from one single file is too difficult.  Using
subparts to break it down into stages or sections is desireable.  With that in
mind, the only choices are MPD or Zip files.  And, in my mind, Zip is a lot
easier and simpler.

Except that ZIP requires two files to be maintained: the ZIP and the
viewable file.  Well, the server could process the ZIP to send down the
X-LDraw DAT stream (did I say that right?).  But it's more work for the
server.

That is assuming the file will be viewable online of course.  Which would be a
good idea.  And, if it uses lugnet to archive them, will be just so.

Hmm....  have the server split the MPD, zip the contents and send to the user?
An interesting concept.  Sounds like a programming challenge. (1)

I'll put in my two-cents: gzip'ed tar files would be an excellent replacement for MPD. And Winzip handles them OK. -gyug (...) (25 years ago, 7-Jun-99, to lugnet.cad.dev, lugnet.cad.dev.org.ldraw)
