First, the short answer is that supporting RDF is clearly the right thing to do. I'm not sure exactly when this will happen, although I can assure you that progress will be evolutionary. OK, then here are some initial observations/ramblings. - There is an emerging notion of "content", as opposed to "method" objects. Content objects are meant to contain information to be published. Methods OTOH are intended to be used to publish content but are not content themselves. I expect that most "content" objects will allow more or less arbitrary properties. - There should be a way to generate RDF text from content objects. In fact, there should probably be ways to generate RDF for any object and for various collections of objects. I assume that there are one or more reasonable mappings from the Python and Zope Object models to the RDF object model. Such a comprehensive effort is beyond my current bandwidth. :) - I propose to add a standard method for getting an RDF text from objects. I'm open to name suggestions for this method. For example, assume there is a method named ZRDF. You could get a RDF text for an object, a/b/c with a URL like a/b/c/ZRFD. You could also arrange to have the RDF embedded in rendered content. If a/b/c is a DTML Document (content) then you could have the head be something like: <head> ...  </head> ... - There needs to be a way to define schemas (namespaces) for properties. There are a couple of issues here: o We need to be able to define schemas for properties. o We have to be willing to allow multiple properties with the same name, but different schemas. Alternatively, we need to be able to define distinct schema sub-objects that act like property "sheets". Hm. Maybe this is the right way to go. Maybe you can walk up to a content object and add a property sheet in which you specify a schema and the associated property values. This new property sheet then becomes an additional object view (accessed via a tab). From Python, properties in property sheets would be accessed through the property sheets. For example, suppose we had a document, D. Assume we've defined a property sheet, dc (for Dublin Core). To get the title defined by the dublin core, we'd use the expression: D.dc.title Note that property sheets might acquire. So, in the example above, if a value wasn't provided for title in dc, the standard Zope title would be acquired, perhaps after checking that the value was consistent with the dc schema. Maybe property sheets would have ZRDF methods to allow getting RDF for just one schema. o Maybe there should be a way to say that a single property value (e.g. title) should belong to multiple schemas/namespaces. This could be accomplished through acquisition, as described above. - For content objects, it seems reasonable that some extra effort should be made to support a standard simple meta-data schema, such as the Dublin core. I'm not sure how this should be accomplished in the user interface and I'm open to suggestions. For example: - Should there me a way of saying: "I want all of the Dublin Core Properties"? - Is it enough to allow any properties to be defined and leave it up to the user to decide which properties should be defined? - To what degree should properties be tied to specific schemas? How should users define or reference schemas? Should Zope have a tool that lets someone type in a URI for a schema and adds the associated properties to an object? Should there be RDF Schema objects in Zope that should support managing proport schemas? - Should there be schema-dependent property views? (Probably yes. See above.)

- ZSolidDA name error?
by BScherer＠mobile.bam.com 08 Jan '99

08 Jan '99

Howdy - I've just installed ZSolidDA with no problems. I added a connection object to a folder and connected it to the db with no problems. Then I added an SQL Method to test out the connection. When I test the connection I get the following: ------------------------------------------ Z SQL Method at /zopeland / user_count Error, exceptions.NameError: error SQL used: select count(*) from ...<snipped> ------------------------------------------ I'm not sure how to get more info on the error. Any ideas? Thanks Bill Scherer

- Zope 1.9 NT/IIS 4.0 Problems
by Stefan Franke 08 Jan '99

08 Jan '99

I've just installed Zope 1.9 on my NT 4.0 SP3 box and I can't get it running with IIS 4.0 (using serve.py with ZopeHTTPpublisher it works fine). When I try to access the management screen (or any other screen) via http://my-domain/cgi-koeln/koelnzope.exe/manage (this is the valid path - 'koelnzope' is the installation name) I get the "Sorry, an error occurred" message with the traceback  The 'koelnzope' system service is running, and the directory settings for the cgi-koeln directory are ok AFAI can say. Any ideas?

- Virtual Hosts
by Jonathan Bradshaw 08 Jan '99

08 Jan '99

Does Zope support virtual hosts? If so, which way works best? I tried faking the root via the CGI call (via Zope.cgi/MYHOST/$1) which would work except Zope insists on putting a "base href" header in the output file (for what reason I cannot say) and this tends to hose it up.

RE: [Zope] - Zope/ODBC and MS Sql Server 6.5 connection

Instead of picking the ODBC connection from the select list, type in a connection string in the box below it. Connection string sytax is pretty baroque.

- Convert database date to Zope date
by Michael Grinder 08 Jan '99

08 Jan '99

How does one convert a database date value to a Zope date value. I'm trying to use a date value retrieved from a query of a MySQL database in the var command with the date formatting options. If I just use the raw value from the query, I get an error. Is there a way to convert this to a Zope date data type? There may be multiple variations of this message posted to the list. It looks like the post form at egroups.com isn't working correctly. Sorry if there is any duplication. Michael Grinder

Are there any adapters for oracle8? I read that the DCOracle adapter is going open source, but this hasnt been reflected on the digicool site yet. If I wanted to hook zope to oracle8, how would I go about doing it? Or should I wait a bit? thanks jeff

- Building Zope source dist on Win32
by Robin Dunn 08 Jan '99

08 Jan '99

I have significantly hacked up David Ascher's compile.py script to be able to generate nmake compatible makefiles from Setup or Setup.in files. So why am I telling all the Zopsters about it? Well becuase I have also modified the build scripts in the Zope 1.9.0 source distribution to use this compile.py script giving the ability to build everything for Win32 with just the w_pcgi.py or wo_pcgi.py scripts just like on unix. The compile.py and modified Zope files are attached. Just unzip in the top Zope source directory and you're set to run w_pcgi.py. This assumes that python 1.5.1 is installed, VC50 or VC60 is installed, python.exe, nmake.exe, cl.exe, and link.exe are accessible on the PATH, and that appropriate environment variables are set for the tools. -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ Try http://AllDunn.com/laughworks/ for a good laugh.

- PCGI with Xitami
by Robin Dunn 08 Jan '99

08 Jan '99

One little gotcha about using PCGI with the Xitami webserver (http://www.imatix.com) that should probably be added to the WEBSERVERS.TXT document is that the "Full Environment" checkbox needs to be turned on. Once I figured this out then I was able to run Zope and etc. via pcgi on my NT box. I'm using version 2.4c1 of Xitami. -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ Try http://AllDunn.com/laughworks/ for a good laugh.
