i'm just noticing that the StarOffice email program sends mail in some weird format (even though it's set to use ascii). my apologies. oh, and maybe i should contact the KOffice people about WebDAV, too ;) Jens Vagelpohl

Ahh, shameless plugster, I have one for you -- convince them to add WebDAV support to allow storage on a remote server!

I've used Amos' work a bit, so I can describe some neat things about it. As for editing, well, it's pretty neat. You can edit the XML Document as a whole, or you can go to a specific element (by, what else, adding /manage to it) and get a TEXTAREA to edit it. Surprisingly, the element attributes (right jargon?) show up as editable Zope properties. Let's say you go to an element and add a property. When you look at the XML, an attribute has been added to the element. What's particularly nice about this is that it doesn't version the entire XML text, only the Zope representation of the element. This naturally means that the cache manager can swap out the elements that aren't being used. Amos created a "slide show" demo for me to replace my clumsy way of doing presentations. I can now write the slide show material as one big XML document. The body is still written as structured text and an attribute signals its format. The elements acquire a document that uses DTML to render the contents into HTML, including previous and next buttons. I can also do conditions to see if, for instance, a slide has been marked private. Needless to say, I can have multiple presentations of the same data, or even ship the XML back in toto to IE5 or Mozilla with a style sheet. I very, very much like how Amos has done this in a way that reinforces the good things about Zope rather than a me-too approach. URLs march into the tree of an XML document. Try that with other stuff. Elements can acquire a management screen and different templates for rendering. Try that with other stuff. I'm particularly excited with the prospect of hooking up the Catalog and indexing elements individually, as far as I know there aren't any open source indexing systems for XML yet. At the same time, Cathi Davey here has taken steps to give Zope objects a DOM interface. One particularly interesting use of this is to use XQL as a query language for Zope. In closing, there is now a bunch of stuff in Zope that provides a basis for people to come up with interesting ideas and extensions. It ought to be exciting! [P.S. could someone on the XML-SIG list post a reference to Amos' message?] --Paul > -----Original Message----- > From: Tony McDonald [mailto:tony.mcdonald@ncl.ac.uk] > Sent: Wednesday, July 21, 1999 4:46 AM > To: Zope List > Subject: Re: [Zope] ANNOUNCE: Zope/XML Roadmap > > > This is really good news. > At the moment, I go through a *lot* of hoops to get my study guides > into an XML format (from RTF) and then into SQL so that they can be > delivered through a Zope frontend in good old HTML.

The database, now that's a different story. Unfortunately I'll give the standard line here -- if it becomes important for a consulting opportunity, we'll look at it. (Surprisingly Java seems more important to the industry analysts than potential paying customers.) Otherwise, we'll encourage a community effort. > Aside from the porting effort I realize that there are speed issues, > but for some of us portability and the simple extensibility offered > by the JPython /Java combination outweigh speed considerations. I'm pretty shocked to hear a claim that Java is portable. Seriously, do the xBSD, Mac OS X Server, and other non-standard platforms have reasonable Java? --Paul

Bulk insert in Zope's ZPyGresql
by HCSCCS＠prudential.com.my 21 Jul '99

21 Jul '99

Hi. I'm beeen using Zope-1.10.3-src, Zap-1.10, RedHat 5.2 and lately ZPyGresql Database Adaptor. Okay, the problem is can I do the aboved. For instance, I put a few checkboxes (the amount is dynamic) on the page. Then the user will click on the items they want to borrow and press the submit button. After that, the next page will insert all this entries into records in a postgres table. Is it possible to do this? How? If not, any alternative to this kind of borrowing system?? Please reply to my personal address, hcsccs(a)prudential.com.my as well. Many thanks, PauL ChunG

In the meantime, the actual functionality is there, even though the tab isn't. If you type in the url: Control_Panel/Products/manage_importExportForm for your site, you will get the import/export form.
