So "union(base, extension)" would apply the extension profile to the
base profile? And "snapshot - base" would create a diff between a
snapshot and a base profile, so that union(base, diff) would be the same
as the snapshot?

yes

I still don't understand what your diffs look like. Are they XSLT files?

The output of the algebra would not be diffs per say, but either base
or extension profiles you would want to apply. The operations of the
algebra could certainly output an XSLT transform that represented the
operation. I would imagine you would want to persist the equation you
used for a given base profile so as to do further operations.

GenericSetup and CMF currently just depend on Zope, nothing else. There
was some discussion about shipping Zope 3 (and therefor Zope 2) with
lxml. As long as this is not the case, it might be hard to convince
people that GenericSetup should depend on lxml. Nevertheless I think
exploring the possibilities lxml provides is worth the effort.

Sure.

I guess I had something in mind along the lines of being able to
represent an algebra (maybe a form of set algebra) for profiles.

So at a broad level maybe something like:

intersection(a,b)
union(a,b)
intersection(a.skins.layers,b.skins.layers)
union(a,b) - intersection(b,c)
... these haven't been well thought out.


So "union(base, extension)" would apply the extension profile to the 
base profile? And "snapshot - base" would create a diff between a 
snapshot and a base profile, so that union(base, diff) would be the same 
as the snapshot?



Considering order is important in various places, then these amount to
fragments of comparison rather than single element by element
comparison, which is sort of amounting to your idea of lots of small
files and layers.

So this is different than a line by line diff of canonical forms.

If I were actually try something like this, my toolist would be lxml which
offers up libxml's XSLT and RelaxNG support. I would hope that anyone
creating their own export import handler with an associated xml form
would also supply a relaxng schema of this.

That said, I can't see much context here, but just thought I'd mention it..


ProxyFieldProperty tries to map persistent Zope 2 data to Zope 3 fields 
that can be used in formlib.


I couldn't find something better for Pdata than the Bytes field and 
FileWidget. I agree this is not optimal. But this is only used if the 
file data is modified using the form, which should not happen very often.

PData is there for a reason, unravelling it into a string is often not 
the best thing to do.
