ANN: Experimental zope->static html mirror external method
by Dr. Ross Lazarus 05 Jun '99

05 Jun '99

Anyone needing to write a static html rendition of a zope site to a file system is welcome to try a very rough pre-alpha external method. fileme.py and fileme.txt are available via anonymous ftp at rossl.gmp.usyd.edu.au - or ftp://rossl.gmp.usyd.edu.au/ if you need to use a web browser. A more stable product will eventually appear. Please only try this release if you like to live dangerously....wget is safer and can probably do a better job. Bug reports, fixes and constructive comments to rossl(a)med.usyd.edu.au

Changing default new document contents
by Mitchell Marks 05 Jun '99

05 Jun '99

(I swear, I read the answer to this earlier today, but now cannot track it down.) Is there a document or method which gets copied or instantiated to provide what's put into a new document (or method) by default? I mean the  <h2></h2> <p> This is the  Document. </p>  To put it the other way around, can I modify or replace that, for a folder, by saving the different version under a reserved name id? And expect that then subsequent new documents anywhere under that folder will start out with my modified starter text. Somewhere I got the idea that dtcTemplate was the reserved name, but that doesn't seem to work.

What are the differences between DTML Document and DTML Method?
by T. C. Huang 05 Jun '99

05 Jun '99

Hi, Maybe this is a FAQ, but it does appear in the documents about Zope I've ever seen. Any one would like to make me clear? Thanks! T.C. Huang

So yes, this expensive fork happens for every request. It's no different, however, then other CGI overhead. One of these days, someone is going to write a mod_pcgi module for Apache, and take that expensive fork out. For light loads, it's really not noticeable, but for heavy loads, one fork per request gets heavy. ZServer is noticably faster in this regard than Apache. > > I've used bbb.py from the Zope 2 distribution to create XML > transactions for 0.. 9211505 and 11844613... 11847812 (but that still > leaves 9211505..11844613 in limbo) > > unnh... so what are my options now? > Well, first realize that corruption is corruption, there may be no way to get some of your info back from the lala lands.

Uh yeah, the whole XML thing isn't complete yet. The dump to XML is really for database inspection, not manipulation or transportation, for the moment.

looking for testers of a slashdot-clone zope product
by Butch Landingin 04 Jun '99

04 Jun '99

Hi ya all, I've written a slashdot-like zope product and it's almost ready to be put into the contrib page, but it needs two things before it's ready to go: 1) it's packaged in a zip format, not the tgz format that all the other zope products are packaged in -- if you can help me do the conversion or do it yourself, I'd like to hear from you; and 2) a last minute sanity check -- I need a couple of people to just install the package on their zope sites and check to see if it at least isn't broken when they install it. It uses Ty Sarna's TinyTable product so you should have that working on your setup if you plan to volunteer. I've tested it on version 1.10.2 and 1.11.0pr of Zope, but I'm hoping it should work fine on Zope2 versions as well. It would also work without the TinyTable product, but with some loss of configurability, so I'd rather have it tested with that functionality intact. If you want to volunteer, just send me some email, and I'll pick the first couple of people who replies, and send them the package. I'd rather not clutter this mailing list with the actual package, because its about 154K in size. I'll probably request to put in the contrib page after the conversion and sanity checking, so it should be available (barring any unforeseen barriers) to Juan and Alice in a few days.

Re: [Zope] FYI: Portal Toolkit Slides and Demo available

>Just to reiterate, the Portal Toolkit is not yet available, it should be >out in beta this month. Amos, This is very timely development for me and I can't wait to access it. Congratulations to the Zope team. About, http://www.zope.org/Products/PortalToolkit/Tour/Images/demo5.gif The advanced search in the demo allows for a focused search of Zope catalogue items, great, but could the metadata schema or search categories be extended to include Dublin Core(DC) Metadata standard? see http://purl.oclc.org/dc/ Although there are 13 elements in the DC standard, technically none are required, however using DC tags enables more accurate distributed searches and the possibility of an external (to the Zope DB) metadata repository that would have a namespace that conformed to a *standard* and was indexable by external webbots, agents etc. or addressable by a distributed search protocol such as Z39.50. see http://lcweb.loc.gov/z3950/agency/ I believe the incorporation of search facilities BETWEEN Zope portals (in future versions) would add a great deal of value to the proposed portal system. Just don't ask me to build one!!

Amos Latteier writes: >Just to reiterate, the Portal Toolkit is not yet available, it should be >out in beta this month. Waiting on tenterhooks... Yesterday I read Philip Greenspun's book on Web publishing (http://www.photo.net/wtr/thebook/) and much of what he suggests seems like a natural fit to the Portal Toolkit. I'd recommend everyone check it out; the complete book is on-line, though it's well worth buying just for entertainment value. I've never pushed strongly for using Zope on our Web site (www.mems-exchange.org) for a few reasons: 1) Another programmer had already done some work with Java servlets, so we have some servlets to do various things. However, I've found that Java is really awful and cumbersome for Web programming. (But without automatic reloading of ExternalMethods, Zope isn't much *less* cumbersome for tasks that can't be handled in DTML.) 2) A fair amount of source code reading is still required, and Zope is so full of cutting-edge Python technique that it's not easy even for a long-time Python like me; for a new Python user, it would be deadly. 3) I still haven't really figured out what the idioms are for implementing complicated forms. DTML is sufficient for simple forms with 2 or 3 fields, but if you have a 22-field form with complicated interactions between fields, DTML won't cut it. At DC, do you write ExternalMethods for such purposes, or full-blown products? How do you debug them without going insane from manually reloading ExternalMethods all the time? However, the Portal Toolkit may well prove to be the wedge for getting Zope on the site. I've already done a few simple Java servlets for registering users and presenting customized pages for a user, the intention being to turn www.mems-exchange.org into a specialized portal aimed at MEMS researchers and users of our virtual fab. People would have a single page which listed all of their ongoing jobs, recent status changes ("Your etch step #4 has completed; click here for metrology data"), MEMS news of interest to them, and similar info. If the Portal Toolkit could be used for this, it would save a *tremendous* amount of effort and wheel-reinventing. if you need someone to try out an alpha, let me know... -- A.M.

ANN: New category in ODP
by Michael Bernstein 04 Jun '99

04 Jun '99

Greetings fellow Zophisticates, I have just added a new 'Zope/Presentations' sub-category to the Open Directory Project, in http://www.dmoz.org/Computers/Software/Internet/Servers/Application/Zope/Pr… It currently contains links to the talk given at the WWW8 and the ZPT demonstration. Also, I'd like to take this opportunity to invite the members of this list to add URL's to the directory if we've missed any (you don't have to be registered as an editor), and please check out the Open Source ( http://www.dmoz.org/Computers/Open_Source/ ) and the Application Server ( http://www.dmoz.org/Computers/Software/Internet/Servers/Application/ ) categories, as well. Keep on Zoping! Michael Bernstein (webmaven).
