Sorry for HTML! I tough I used "text", but I guess I didn't... Sorry! -----Message d'origine----- De : Menard.Jean-Francois(a)hydro.qc.ca [mailto:Menard.Jean-Francois@hydro.qc.ca] Envoyé : vendredi 4 mai 2001 15:00 À : zope(a)zope.org Objet : [Zope] LiveLink "converters" We just got a demo of LiveLink, a document manager system. They have an Intranet module wich is REALLY like the Zope one. In fact, it's almost de same! I found a number of similar functionalities between them, but there is a couple of features in LiveLink wich I found interesting: - If a user upload a document, the programmer can use it directly. There are automatics converters for many formats: PDF to HTML, Excel to HTML, Word to HTML, Word to PDF, etc. You can develop your own converters if tou want. Example: Someone upload a report in Excel. In your website, you can put a link to a PDF version, or show it in HTML automatically! - When a user is logged, he sees only the documents he can manage! Much simpler interface! - The interface is internalionalized. So, I guest my questions are: - Any plan for a Zope interface internationalisation ? I know, we could translate the interface ourself, but we want to upgrade sometimes... - Any plan for "converters" ? I think it would be fairly easy, no? - Could hiding unauthorized objects been possible? I know that I can manage that in DTML, but I mean in the default management interface? Any thoughs?

Re: [Zope] Summarization and Zope
by Chris Beaumont 04 May '01

Hi Assum, It's 'HTML::Summary' http://search.cpan.org/doc/TGROSE/HTML-Summary-0.017/lib/HTML/Summary.pm (I'm enclosing the info for it at the bottom of the page) What I was thinking is that it might be possible to parse a given rendered page just before actually delivering it in the RESPONSE object, and insert a short summary in the meta-description tag.. on the fly.. I also wouldnt be suprised if the PERL summarization module might also be able to be coaxed to give us keywords.. (the 'fork words' in the 'tree') There are two guys at a company called Glucose that make a similar tree-summarization product for the Mac, (it works amazingly well) and I suggested a similar thing for them around two years ago (to be used with static pages..) and they actually turned my idea into a commercial product.. Unfortunately, it is Mac only and cant be used with Zope.. I didnt ask them for any money, but they did put my name in the about box *laugh*. Of course now that I'm building sites in Zope, it's not really practical for me to use anymore. But I really miss that functionality.. I work on a scientific site and as we move more and more of it to Zope, the ability to generate a good meta-tag summary automatically would be a godsend. This insert doesn't sound like it would be difficult.. I'm doing a similar thing with titles for some of the pages on the Zope part of my site.. I'm just not enough of a PERL hacker to know the best way to go about creating the hooks between Zope and PERL.. -Chris Ausum wrote: > > Chris, Would you please specify what is the summarization module you've known > about?

Re: [Zope] Uploading images - no image!

Apparently, your "file" does not have the correct type. This may happen, if the "enctype" attribute if your "form" is not "multipart/form-data" (as someone else already told you). Note, that it must be "multipart/form-data" and *NOT* the content type of your image! Dieter

Xron not firing reliably
by Capesius, Alan 04 May '01

04 May '01

I'm using a sendmail operation in three identical xron methods. The events are scheduled for 12:00:00 each day. They can be triggered manually or scheduled for other times, but they do not fire reliably over time. That is, they will work the first and maybe second time but will not fire repeatedly over several days. No output goes to the STUPID_LOG_FILE when this happens. Restarting the Zope service will activate the unfired events and log them. Anyone have any ideas on what might be going on or not going on here? I'm currently running a test with a simple test logging event that fires every minute to see if it will eventually break down.

Re: [Zope] Changing the UNIX passwd from zope / python script

I am a newbie to both zope and python so i would > need explicit instructions if there is a solution. Are you really sure, you want this? Unless you use HTTPS (or another secured transport), your passwords are send with each request almost in plain form (if you use Basic Authentication, Zope's default). It is not too difficult to snif network traffic. In the above mentioned setup, your Zope passwords are not very secure. If Zope and Unix passwords are identical, your Unix passwords are neither... I definitely would not want to have this. If I would, I would look for the PAM module (there is a Python wrapper, but it requires root privileges). Alternatively, I would use a PTY (pseudo terminal) and automate 'passwd'. Dieter

I think, you have (at least) two options: 1. install a working ZDiscussion product 2. if this is impossible: empty the current definition of "manage_beforeDelete" in "Products/ZDBase/ZDiscussions.py" line 195 (replace its content by "pass"). Enter your folder, delete the ZDiscussion objects, and then get rid of ZDiscussion altogether. Dieter
