[Zope] HiperDom available outside of Zope?

[Zope] Difference between Methods and Scripts?
I see that the latest version of the O'Reilly Zope book now talks about Python and Perl *Scripts*, but refers still to DTML and ZSQL *Methods*. Does this reflect some actual conceptual difference between a Script and a Method, or is it simply because of the burden of also renaming DTML, ZSQL, etc? I understand that it is recommended that logic be implemented using Python/Perl Scripts, while DTML Methods should now be reserved for presentation; but I wasn't sure if that could be the rationale for the Scripts/Methods division, since ZSQL Methods don't really fall into the presentation category. If the difference is explained in the book, please excuse my having missed it; if not, I'd welcome an explanation, and perhaps it would be worthwhile including it in the book too.

Re: [Zope] DC request re: Objection to Python Script Name
When I 'jumped in' (nod to Chris Withers :-)) with my promotion of ZMethod, I'd missed Evan's announcement that he'd decided on Python Script - I thought it was just another suggestion and we were still in the middle of campaigning for the upcoming second poll! I'm actually not that averse to Script; it was ZMethod's OO associations that I liked - but if Michel thinks that such an association is actually not appropriate in this situation, then I'll bow to his greater Zope understanding. I agree with him that the new name needs to make it into the book, and Script is a reasonable choice. Is it intended to rename DTML Method, ZSQL Method, etc to be DTML Script, SQL Script, etc? For the sake of consistency I'm hoping so, and I think it's important that these revisions also make it into the book. Onwards! Hamish Lawson Do You Yahoo!?

Re: [Zope] Objection to Python Script Name
Chris Gray: I think there is a logical objection to this name [Python Scrpit]: inconsistency with "DTML Method" and "ZSQL Method". Chris Withers: These are old, horrible and will hopefully be re-thought and given different names ;-) ZIP Method (Zope Internal Python Method) ZoPy Method PyZo Method ZPython Method :-( All imply there is soem difference between the Python used by Zope and any other python ,which isn't, and never should be, the case... This is why I proposed Python ZMethod. I further propose that ZMethod be used generally for anything that Zope considers a method (but which may not necessarily be a method in the implementation language - here, Python). Thus we'd have DTML ZMethod, SQL ZMethod, Perl ZMethod. This puts the decoration where it is most appropriate, i.e. ZMethod, and leaves us to qualify it by the natural name of the implementation language - Python, Perl, DTML, SQL, Tcl, whatever.

[Zope] ZMethod and language variants
Considering that there aren't (yet) other language variants, and that I would usually use the restricted kind, I would normally just say "ZMethod". Only if there were some potential confusion would I say "Unrestricted zmethod", or the full title. My proposal that ZMethod be used generally for anything that Zope regards as a method would mean that there already are other language variants, such as DTML ZMethod and SQL ZMethod.

[Zope] Python Zope Method as option for renamed Python Method?
In the poll currently underway on renaming options for Python Methods, the most popular choice so far is to leave the name as it is. It could just be because people don't see enough benefit in changing what's already there, but I think it may be that people actively feel that the term 'method' captures some technical essence. However, we still have the problem of disambiguating between a method in Zope's eyes and a method in the implementation language. How about calling anything that Zope regards as a method a Zope Method? That would then give us Python Zope Method, Perl Zope Method, DTML Zope Method, SQL Zope Method, etc. Is it too late to add the option for Python Zope Method to the poll? Hamish Lawson Do You Yahoo!?

[Zope] Python ZMethod (was Python Zope Method as option for renamed Python Method?)
I suggested the term Zope Method for anything Zope regards as a method, giving Python Zope Method, Perl Zope Method, DTML Zope Method, SQL Zope Method, etc. But Chris Withers thought those to be too long and unwieldy. OK, what about ZMethod? Thus Python ZMethod, Perl ZMethod, DTML ZMethod, SQL ZMethod. I was quite favourably disposed toward Operation, but I wanted to keep 'method' somehow as it I felt it better brought out the acquisition aspect. Hamish Do You Yahoo!?

[Zope] Roles as members of other roles?
I've not kept up with all the different mechanisms for users and groups that are currently under development in the Portal Tookit and other activities. Do any of them support the idea of a role or group collectively being a member of some other role? For example, if there was a MarketingStaff role consisting of a number of users, then various other roles throughout a company website could be allocated to the MarketingStaff group collectively rather than having to be allocated individually to each member of this group.

[Zope] Generating products that perform a smart clone of a master site?
I'm exploring the use of Zope for creating learning environments in higher education. One of the requirements is for a tutor to be able to create a mini site that includes static files along with more active objects like discussion boards. Furthermore they need to be able to make different 'instances' of this site for use by different groups, such that each instance of the site conatins unique instances of any contained active objects (such as a discussion board). The obvious approach would be to just copy and paste the folder containing the master site, but there are a couple of problems with that: (1) changes to the master site will only be reflected in new instances of the site, and (2) a lot of static files could be getting copied each time. What I think I need to do is to develop a facility that makes a tutor's site into a product. Instantiating such a generated product should make a smart clone of the master site, smart in the sense that only active objects are actually cloned, but static files are shared among all instances of the site. I suspect that ZClasses might be involved to achieve this, but are there any issues with the fact that a master site could contain folders? Furthermore I'd like a tutor to be able to visit their productised site to update it, without seeing a lot of alien stuff; changes to the master site should be reflected in all instances of the site. Am I on the right lines here? Any pointers would be appreciated. Hamish Lawson University of St Andrews, Scotland Do You Yahoo!?
