Hi Lenya devs,
to sum up the recent UUID discussion:
From my point of view, the next step would be to use UUIDs to
identify documents. That would mean that the default persistence
mechanism would store documents in a flat structure which would
look like this:
550e8400-e29b-11d4-a716-446655440000
550e8400-e29b-11d4-a716-446655440000.meta
is 550e8400-e29b-11d4-a716-446655440000 (without suffix meta) the
actual content? I guess you are refering to the reference to the
resource,
right?
It would be the name of the file which contains the actual content.
I think this is exactly the problem, that a URL doesn't have to
correspond to exactly one resource
within a repository, be it referenced by UUID or whatever and I think
this is what we need to
change within Lenya
But how is this issue related with the actual content storage?
The mapping from URLs to resources isn't subject of this thread,
or am I getting this wrong?
550e8400-e29b-11d4-a716-446655440231
550e8400-e29b-11d4-a716-446655440231.meta
550e8400-e29b-11d4-a716-446655443402
550e8400-e29b-11d4-a716-446655443402.meta
Do you share this opinion?
if we are talking about a default persistance manager then yes, but
if this would be hardcoded, then no ;-)
The question is if the persistence manager should get any
information apart from the UUID. If only the UUID is provided,
there won't be a chance to use human-readable file names.
right, IIRC this is what Jackrabbit does and I think it's wrong, whereas
it might be good
practice, but I think one should give people the freedom to make also
use of the path
But if you pass information which is a concern of a certain layer
to the layers below, you lose the advantages of the layered architecture ...
If not, how do you envision the storage structure?
I am not sure if we are confusing actual storage with referencing?
well, in order to show what I think how it should be implemented I
have started
something at http://svn.wyona.com/repos/public/yanel/trunk
whereas it's not quite working yet and also got distracted on
versioned published interfaces ... I have done this because I am
afraid I will never be able to explain my ideas, so I will try to let
this code speak.
OK, I'll take a look at it as soon as I find the time.
no problem. I didn't mean the actual code, but rather the ideas
illustrated by this code :-)
OK, so I hope I get the ideas by reading the code :)
