[Zope] dtml-tree and REQUEST.form
Hi, I'm currently implementing a tree using... dtml-tree. In the document I use, I just have the tree and a table which desplays results according both to the tree state and some form data (passed through REQUEST.form). I.e. my URLs should look like the following : http://xxx.xxx/xxx/yyy/zzz/MyPage?MyVar=toto when I first open the page, and it SHOULD look like http://xxx.xxx/xxx/yyy/zzz/MyPage?MyVar=totoe-tree=tree-stuff. You guess - it doesn't look like this at all. This because the dtml-tree tag doesn't use the REQUEST.form dictionnary data to build its URLs. Instead, it just discards, in the URLs it builds, every single GET variable you wish to use. I'm currently patching the TreeTag.py file to support the REQUEST.form data, but I'd like to know if someone ever had this problem, and maybe corrected it - I hate patching. Also, if there is no other solution, I'd like to know if there are peolple intersted in this patch.

[Zope] SQLProperties - missing files?
Does anyone have SQLProperties working? The product on Zope.org seems to be missing the 'dbspecific' directory of SQL files. If anyone can send me a sample of what those files should look like I would appreciate it. This product seems like it would help in my quest to reduce the size of my "data.fs" database. Shouldn't it? Also is there any way to use the Zope Catalog with SQL data? It would be great to have full text searching on my SQL data.

[Zope] get objects DTML Document having Property order...
Hello,
I want to do :
dtml-in "objectValues('DTML Document')" sort=order
...
/dtml-in
I have some DTML Documents which don't have the property "order", and I
don't want to consider those documents in my loop. But if I put the
"sort=order" option, Zope raises an error
How can I do ???
Thanks a lot,

that makes it so the sorting code will consider fields that don't exist
to have the value "None". This makes it so you can sort the natural

Re: [Zope] Before I install zope
I'd say the easiest way is to give them different ports: give zope1 port 8080 and zope2 port 9080 If you've installed the Zopes as NT services you need to change the parameters to the services in regedit: goto hkey_local_machine/currentcontrolset/services/zope2 and change/add a parameter to change the default port base. The parameter you want is -P (upper case P) if you change/add it so that you have -P 9000 on the second instance then that user would connect on port 9080 for http and 9021 for ftp.

Apparently if you provide a unique name and user names you can do this. My question is, "How would you gain access to each individual Zope?" For instance, I would like "manager 1" to have access to "Zope 1" on port:8080. He will use Zope in tandem with his static web. I then want "manager 2" to have access to "Zope 2" in the same capacity as "manager 1." They will also use thier own separate product preferences.

Re: [Zope] Use of lambda expression in DTML
In brief: I get a NameError when invoking "filter(...)" from DTML. I thought this
was a built-in python method, so I'm a bit puzzled.
Python's ideas of 'built-in' is simply any method in the module
stored in the global variable called __builtins__. Any code executed
with a non-standard global variable space may or may not have the
same set of builtins as normal Python code.
Unfortunately Zope does not expose all of the 'builtin' python
methods to DMTL expressions. Some obviously need to be cut out
(such as 'open') for security reasons, but the reasons why others
were dropped are less obvious.
If you really need any of the missing builtins back in you have a
couple of choices. Both require you have full access to your Zope
system.
If you want the function available throughout your Zope system
simply edit DocumentTemplate\DT_Util.py. Look for the list
beginning 'None', 'abs', 'chr' and simply add 'filter' into the list.
Alternatively if you dont want to patch Zope directly, create an
external python method that exposes filter.
5) In the dtml-tree tag, I change it to:
dtml-tree
Technical
leaves=dtcTemplate
branches_expr="filter( lambda f: not
f.hasProperty('blockTreeBranching', false), objectValues(['Folder']) )"
which, all things equal, should DoTheRightThang.
Even if you make the filter function visible as described above, this
still won't quite work. For example the method 'objectValues' is not
in scope within the function. The way around this is to pass in an
extra parameter _vars. Try (untested):
branches_expr="filter( lambda f, _vars=_vars: not
f.hasProperty('blockTreeBranching', 0), objectValues(['Folder']) )"
and it might work.
Alternatively use something like a PythonMethod, or even a DTML
method and simply write the filter loop out in full using 'for' or 'dtml-
in'.

Re: [Zope] Zope Email (syndication)
Yup, this sounds like mail-in content to me, which is what I'm after :-) If the goal is mail-in content, I'm not sure I understand IMAP to be anything approaching what you want: IMAP doesn't ACCEPT messages, at least not any of the IMAP servers I've seen, it serves messages up to clients (one of which could be Zope, like WorldPilot does). MailMan supports external archivers (how, I don't know, just saw it mentioned), and with the right archiver plugged in, that would give you the capability to archive email lists however you wanted. Also, I saw mention of someone using a script to archive msgs via WebDAV from mailman. The same sort of script could be used with any inbound MTA (postfix, qmail, sendmail, exim, etc...). Here's a URL to the post in Mailman-Developers: http://www.python.org/pipermail/mailman-developers/2000-February/001826.html I have written an archiver that uses WebDAV to archive messages [with or without decoded attachments] to a WebDAV enabled web server. I'm currently using Apache, but there is no reason why it shouldn't work "out of the box" with Zope (Zope has a WebDAV enabler). Email if you want patches/code... it works *very* well. We will be going into full production with it in the next week [www.bebusy.com]. A webdav-aware script, without mailman, could give you very simple mail-in access to Zope. With Mailman, a full alternative archiver. I'm just getting started with Zope, so I won't be coding this up, but hopefully this is enough for someone else to go on. Also: I'd like to voice some opposition to expending the effort to turn Zope into a full-blown SMTP MTA -- that's a lot of effort to down the "not-invented-here" path, complete with its' own security issues, etc, to be tackled. Building on other mail systems with proven scaleability (i.e. what happens when your Zope store is getting 100,000 message an hour?) makes more sense to me. Seems to me that tools to integrate Zope with existing mail tools would see the widest use.

Re: [Zope] Use of lambda expression in DTML
Chris McDonough wrote Nope. Lamba, filter, reduce, and map should IMHO not be part of DTML. Actually, exprs probably shouldn't be in there in the first place. People are trying to use DTML as a way to process non-UI elements. This is a slippery slope, and leads to something like PHP or ASP. My opinion is this: Generate and format your HTML with DTML, and do everything else in Python. This gives you the added benefit that you can change the return values of functions by changing the Python code without having to muck with DTML, which is painful any way you look at it. Until PythonMethods are back in the distribution, you can't stop people from using DTML for this stuff - the only alternative is to give everyone who ever needs to do something more than simple HTML access to the file system. I can't see that happening on zope.org, or many other sites. I agree whole-heartedly that DTML's expr syntax is nightmarish and needs to be deprecated - but right now there's nothing to replace it with. As far as the issue at hand - whether lambda/map/reduce/filter should be allowed - the simplest way to enable them for PythonMethods also enables them for dtml-expr.

When someone clicks on an item in a list, I would like to be able to pass the id of the item above it and below it. For example, Given this result set: Title Desc - -- Item 1 This is item 1. Item 2 This is item 2. Item 3 This is item 3. If the user click on Item 2, I want to pass the id of Item 1 and Item 3 to the next page. Does either dmtl-in or ZCatalog provide a variable that stores the id's for those (i.e. something like 'sequence-1' and 'sequence+1')?

Re: [Zope] Q: Using WebDav to edit Zope DTML Methods. SOLVED!

Hello,
I have been using Zope to set up a new web site for documentation and
maintainance os a large software project. Until now I have been using a
combination of LocalFS and ftp to edit content. Neither method is
perfect especially since I often work from my laptop at home which is on
the wrong side of the firewall and can't get ftp to work.
Just the other day I discovered WebDav and life looks much better. I
can tunnel my connection to port 8080 through ssh and manage my Zope
site from home. One problem remains:
When I use "get" or "edit" to get a DTML method (web page in my case)
from the site I get a page with all the DTML tags expanded. This is
clearly useless to me since I don't want to edit the rendered DTML but
the original code. Am I doing something wrong (I hope so) if so what
should I do?
I am using Zope 1.whatever but also tried Zope2. I am running on RedHat
Linux 6.1 with Apache web server but I point the WebDAV tools at
http://localhost:8080/ "http://localhost:8080/" i.e. the ZServer. I have tried
the "cadaver"
command line tool and "DAVExplorer" java application with the same result.
Thanks to the info from Martijn Pieters this turned out to be trivial.
The unrendered source for a DTML method is reached by appending
/document_src to the end of the URL. For example,
http://localhost:8080/mystuff becomes
http://localhost:8080/mystuff/document_src .
In the context of DAVExplorer the solution is to modify the GET so that
the /document_src is appended correctly. Not that this can't be done too
early since the URL is used for other internal book keeping. I found
that the folowing modification works
In dav_explorer/classes/DAVExplorer/WebDAVManager.java make the
following change at line number 119 ...
try {
Response = Con.Generic(MethodName, ResourceName, Body,
Headers);
WebDAVResponseEvent webdavResponse =
GenerateWebDAVResponse(Response,tn);
fireResponse(webdavResponse);
}
... becomes ...
try {
if (MethodName.equals("GET")) {
Response = Con.Generic(MethodName, ResourceName +
"/document_src", Body, Headers);
} else {
Response = Con.Generic(MethodName, ResourceName, Body,
Headers);
}
WebDAVResponseEvent webdavResponse =
GenerateWebDAVResponse(Response,tn);
fireResponse(webdavResponse);
}
... note you don't need to change PUT since PUT does the right thing.
I've tested this out quickly and it seems to do what I want.
The sources to DAVExplorer can be found via a link at www.webdav.org to

The properties for the source list looks like... n:source n:link n:src /test_dtml /n:src n:dst /test_dtml/document_src /n:dst n:link /n:source ... the property tagged by dst is the link to the unrendered source. What I really need to do is extract this from the properties rather than simply appending /document_src onto the end of everything. As you point out (partially) document_src has no meaning in the context of some objects and also other WebDAV servers may use a different syntax than simply adding /document_src on the end of the URL. At least this works for Zope. For my next trick ;^) I am going to try to make it general, as you suggest and add a "Get Source" menu option so that the user has some choice over getting the rendered or unrendered source. Also, I am working on adding an "Edit" option which does a "get source" into a temp file then fires up the user's editor of choice and a thread to monitor the modification time of the temp file. Each time the file changes it gets put back into Zope. That way the user can use the "Save" command on the editor. (By the way I E-mailed the authors of DAVExplorer to get their input. waiting for a reply.) Anyway I'm having fun and getting somewhere at last!!

It's having it in DTML that bugs me, for reasons that |have to do |with separating HTML-like stuff from the stuff that actually runs the |site under the hood. I take your point, but it's making an assumption that map, filter, and lambda are going to be used for business logic. In my case (see original topic) would you argue that what I'm trying to do is business logic or presentation? Many apologies, I caught the thread at the tail and didn't look back to see the origin of the topic. This is pretty stupid on my part. I would say that you were indeed trying to do presentation logic. And furthermore, I would say that my arguments were offbase and pretty much knee-jerk reactions to the possibility of what might happen if functional kw's and builtins were added to DTML. After considering it further, it doesn't seem to be such a bad idea if it didn't impact security in any way. It might even reduce the complexity of DTML looping, which would be a good thing. It would most certainly be welcome in Python methods, I'd definitely miss map a lot in Python methods if it wasnt there. If it's something you want badly (and if you haven't already) add it as a feature request to the Collector on Zope.org. Once other folks get past the knee-jerk reaction, maybe it'll sink in as a good thing. In the meantime, you can add it yourself if you like. Hopefully, you'll be so kind as to forgive me. After seeing people post DTML code to the list that they need debugged that computes pay rates, has the shape of an arrowhead and scrolls past the maximum character length of my email client horizontally, I'm a little leery of adding anything whatsoever to DTML, as I think the rest of the folks at DC are. Reducing the complexity of DTML is a good thing, however it can be accomplished. As for HTML-like stuff vs. business stuff wrt to functional expressions: Do you object to CSS, XSLT, and XPath? I can't object to XSLT and XPath, I don't even know enough about them to spell them right. :-) CSS is all about presentation, but AFAICT doesn't have an expression syntax, nor even a way to spell a loop.

Re: [Zope-dev] Z SQL: optional isn't?
On Tue, 30 May 2000 17:09:20 +1000 (EST) you wrote:
I like the optional attribute. I'd like to see
it do more than sit idle in the code.
You don't have to do the typechecking in the 'arguments' box if you don't
want. eg. in your arguments section:
course=""
subject=""
O.k., it appears that I can still use that with
integers. I can live with that. I don't like
setting an integer to what appears to be a
string, but it does work.
select * from enrolments
dtml-sqlgroup where
dtml-sqltest course type=int optional
dtml-sqltest subject type=nb optional
/dtml-sqlgroup
The definition of the 'optional' tag from the docs might help here:
'''A flag indicating if the test is optional. If the test is optional
and no value is provided for a variable, or the value provided is
an invalid empty string, then no text is inserted'''
I should have been more specific. I was
referring to the "optional" attribute of the
*argument* (not the sqltest). I found that
it's coded in Aqueduct.py, but I'm not aware
of any way to set it from the Z SQL method
form.
Hmm... looking at this definition, it seems you have found a bug
(but setting the default value to "" in the arguments section will
provide a workaround). Or maybe 'no value provided' means 'is None'.
Anyone from DC want to provide a ruling? :-)
Originally, after reading the above ("optional"
in sqltest) definition, I'd hoped to be able to
simply list the variable in the arguments
section and make it optional in the sqltest.
After looking at the code, I determined that
this was not a reasonable expectation. (What
if I used two sqltests and it was only optional
in one?)
In the course of investigating this, however, I
found that an optional attribute for an
argument is recognized. It seems like this is
what should be used.
I can live with it either way, but I think that
optional is better than integer_var="". I'd
like to see whatever is chosen documented, and
I'd like to see "optional" removed from
Aqueduct.py if it's not going to be supported.
(Maybe it's used by something else?)

Ok - this should be fixed now in CVS. Part of the machinery that checks whether the user is really allowed to create the type of object they are importing was failing spuriously because it expected the object it was checking to be wrapped (which isn't the case when checking an imported object to see if it can be added).

Re: [Zope-dev] Cataloging LocalFS content
I think, cataloging "LocalFS" content would be nice. I have the following problems with it: 1. "LocalFS" defines various meta types: "Local File System", "Local Directory" and "Local File". Only "Local File System" is a "true" meta type which should appear in the available objects list of ObjectManager's. However, I may well be useful, to select the others, too, in for "find" and cataloging. This could be done, but my concern is that when changes are made to the file system this will cause the catalog to be out of synch until you re-index. How does this work with Zope objects? If you move or delete a Zope object that is cataloged does it automatically update the catalog? 2. ZCatalog uses "bobo_modification_time" in its meta table and for indexing. For "LocalFS" content, this is not the best modification time to use for indexing. It would be nice, if "bobo_modification_time" could somehow be synchronized with the object's modification time in the file system. With the most recent version of LocalFS, the bobobase_modification_time should be the same as the object's mtime in the file system. Please let me know the details if you're seeing anything different. --jfarr ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Re: [Zope-dev] CatalogAwareness for RackMountables
At 12:53 PM 5/30/00 +0300, Itamar Shtull-Trauring wrote: I've been playing around with ZPatterns, and I must say it's very cool - finally you can mix ZCatalog and SQL storage. CatalogAwareness is slightly different than regular Zope objects in that you have to find the ZCatalog in the Rack's acquisition path, but that's about it. IMHO, you don't need to keep referring to self._v_rack to do the cataloging as described, so long as you retrieve your objects from a Specialist; then the acquisition path is via the Specialist. I would suggest that you modify your patches somewhat to reflect this, and use only self.* attributes, not self._v_rack.*. It will improve your forward-compatibility with 0.4.0. The absolute_url function I define here should be moved to the RackMountable class since it may be useful in other situations. I have to disagree with this, since the standard Zope absolute_url method will work correctly, so long as you access a RackMountable by traversing (via bobo_traverse) from a Specialist. If you would like to make your work easier with version 0.3.0, it would be best for you to move the __of__ wrapping from Specialist.__bobo_traverse__() to Specialist.getItem(), as I have done in the working copy of 0.4.0. This will ensure that whenever you retrieve a rackmountable from a Specialist, it will be wrapped in context of the Specialist. Then, by deriving your classes from RackMountable and CatalogAware, you need only adjust for the absence of add and delete hooks. And you'll only need to adjust for that until 0.4.0 makes add/change/delete hooks available for indexing agents. I don't know if there will be a Catalog IndexAgent released with 0.4.0 yet, but there should be one eventually (or perhaps someone will contribute one). ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

In many ways it behaves similarly to the original XMLDocument, except it only creates a single Zope object upon import or creation. XMLImporter This python module allows users to externally import XML content into the Zope database in a 'controlled' manner. The user has full range of control over import parameters. XSLT Method This is a Zope product that wraps an XSLT stylesheet for use in Zope. Like a DTML method, it can be invoked on a ClobXmlDocument instance and return the resulting XSLT transformation. Fourthought provides custom technological solutions based on open technologies. 4Suite is a powerful set of Python tools developed by Fourthought for Web-based applications in areas such as Intranets, E-Commerce and knowledge-management. Elements of 4Suite have been adopted as core XML technologies in Zope and in the Python XML distribution links: Fourthought: http://fourthought.com 4Suite: http://fourthought.com/4Suite/ DOM 2 Spec: http://www.w3.org/TR/2000/CR-DOM-Level-2-2307/ Zope http://www.zope.org contact: [EMAIL PROTECTED] Installing XMLDocument beta --- This document describes installing XMLDocument beta on Unix.

See (XPath: http://www.w3.org/TR/1999/REC-xpath-19991116, and XSLT: http://www.w3.org/TR/1999/REC-xslt-19991116) XMLImporter is currently used as a python based tool to input XML files as Zope Objects. The mapping functionality and XSLT transform are used to manipulate the incomming XML stream into a set of Zope Objects. The transform is applied to the incoming XML to allow manipulation and compression of the incomming XML. See http://216.164.72.7:7780/Wiki/Members/jim/ZDOM/InitialNotes under the heading optimization. The final set of objects created by XMLImporter is defined by the mapping dictionary where keys are the tagNames to be created, and the values are references to python classes. A current limitation of the system is that Zope must not be running during an import. Clob XML Document is a Zope Object that represents a complete XML document. Interfaces are provided to edit the content of the document, and modify how the document is displayed when viewed. XSLTMethod is a Zope Object that applies an XSLT transform to an object. An XSLTMethod can be accessed as any other method of an object. With the ZDOM pakage installed, the XSLTMethod can be

Server setup, as in pcgi/Zserver/Apache w/proxypass, etc? Nothing but straight ZServer/Medusa. Cool, eliminates suspects. Compiled on the machine, or binary distribution? Zope 2.1.1 binary distro. Not sure how it got to be 2.1.4/2.1.6, might have been the other person having problems, or my mistake. But the changes in 2.1.4 and 2.1.6 aren't anything in the Object publisher or Medusa so I don't think it makes a difference. Have you considered trying a source-compile setup? There may have been something in the original binary that gets triggered when dynamically linking (does it do that? I haven't run a binary Zope distribution) to the libraries on your machine. I have witnessed this with X. RH 6.1 2.2.12smp kernel Hardware RAID dual 350mhz Xenon 1 gig ram Vanilla Zope with no DA's, no Apache. BTW, Matthew gave me some advice last Friday to use the setcheckinterval line in z2.py and the performance gains are quite impressive. Anyone who is running smp should try it. It is impressive.

Re: [Zope-dev] New Help System in 2.2
I too agree the new help system looks nice. I was considering at one point jumping up and writing a documentation system for Python/Zope. Unfortunately my notes, not many, are at work. But some things I had in mind were based on something like JavaDoc. I am not a Java expert and have not really used JavaDoc much but have seen some of its documentation. I was thinking it would be nice to have a parser which could extract documentation from source to create external documentation files which could be generated into multiple formats, html, xml, etc. I would have needed to create a documentation format which could be used in source but extracted. I was not going to use docstrings as they are intended for a different purpose and are compiled into the bytecode. I was thinking that the parser could run over a module and extract functions, methods, variables and properties, etc. and create a stub framework on a form. A documenter could then edit documentation for any or all of the methods, save and it would be inserted appropriately into source. I thought it would also be nice if the documentation tree would also parallel the source tree and have a corresponding colorized html rendering of the module for browsing. This way one could jump from documentation to source at will. I was basically making idea notes. I was going to look at the current doc generating and py2html tools available first. Then Starship went down and I couldn't access them. :( I also wanted to see what the DC team was doing. I think it would be nice to see some ideas and processes for what and how Amos and Michel are doing with the documentation and how the community can help. Just some thoughts.

I just talked to Amos and Michel last Friday about that and they researched for a long time, whether it would be better to document the source or to have different files. They both decided it is the best to have the documentation separately. I believe that they looked at the issue from all angles and had good reasons, why they went with the current way. I trust them implicitly. I'm sure that my gut reaction was probably the same one they had, but after careful thought they found a better solution. Furthermore, the help system will become even more than just the screen help. The .py files you see, are just the start of the new API documentation. Oooo. Furthermore, we will include a new DTML reference soon. Do you know about anything else, that should be included? Well if you really want to make it hot, the examples that are in there can keep coming. Web links might not be out of order either. The only problem is that there is no difinitive Zope online docs to link to, to get the most recent info. But when there is, it would be nice to include.

The next task after the 2.2 release is that we will look through the tutorial and see what it does not cover and then add the missing examples in tutorial form. :) Off-site links are okay, but what happens, if I sit in the plane and I need that piece. Amos leans also towards external links I think, but I would rather keep it in the distribution; it is only a couple thousand bytes more and will not increase the distro size too much. A fact is, that most of the Zope Online Help should be the most up-to-date, meaning that we try to encourage developers to update and patch the help system as they update the code. Personally, I see that same thing might happen that happened to Zope. They'll want to get the product out badly, and since the help system is separate, they'll put it off. Our goal is basically to initialize a good, well organized Zope help system, which content is maintained by the developers, read community. I think this is terrific shot at offering everyone a chance to "get it". BTW, if you find any mistakes or want to make additions to the help texts, please send them to me. I hope I will be able to upload a complete revision of *all* the help screens by the end of the week. I have only 80 documents to go. :) Excellent. I am reading it.

Chris Withers wrote: Tres Seaver wrote: who's the CTO? Jim is. Okay, I get the joke now :-) * "persistent" references are effectively required to be immortal: it is _mandated_ that one be able to stringify the IOR, copy it to a piece of paper, put the paper in a bottle, and cast it on the waves; whoever opens the bottle should be able to transcribe the IOR, reify the reference from the string, and communicate with the object (which may be an entirely new "incarnation" created just for this request). This is the sort of persistent reference I meant, it's one of the reasons I like CORBA as a model ;-) A general-purpose, persistable reference in Zope pretty much has to be represented as an absolute containment path I don't agree. What happens when you move an object? The object doesn't change so why should its persistent reference? In a similar way, what happens when an object moves between storages? I reckon it should have the same POID... What you are missing in my description above is that CORBA persistent IORs may not map one-for-one to "real" objects -- there may be many IOR's whose requests are served by a single "real" object. Persistent IORs encode a promise that, if I come back and invoke on the IOR I got from the bottle, the ORB which published it must do one of the following: * locate / activate the corresponding servant object and delegate to it; * return to my ORB a LOCATION_FORWARD message pointing to the place whither it moved; * raise a NOT_EXIST exception if the object has died and can't be resurrected. CORBA IOR's can actually consist of multiple "profiles" each of which encodes a "search path" to find the object: * "endpoint" data -- address information with which to establish a connection to the POA (persistent object adapter) e.g., hostname/IP + port # for TCP, or pathname for AF_LOCAL sockets; * "POA ID" -- a (possibly hierarchical) name for the object adapter which published the IOR; * "object key" -- the ID for the object, unique *within the POA*. Zope objects already have an OID which is unique within their storage; the problem is that there is no useful way to massage an object given only its OID; lots of Zope's machinery depends on knowing the traversal path used to find it. A man with one watch knows what time it is; A man with two is never sure. That's not quite what I meant... An object is unique. It's aquisition context may give it more attributes to play with, but at the end of the day it is a seperate entity. This entity should have a unique, global identifier; it's POID. I think putting a path in front of this identifies the context, but doesn't really do a lot to identify the object. I guess my view depends on _data_ being stored in the object rather than acquired. Is this the case? The traversal path encodes more than just acquired attributes. For instance, it is entirely possible for a single object to be stored in multiple folders: in one folder, tseaver might not even be able to *see* the object, while in another, I might be able to query or modify it, based on the local roles assigned in each folder. (Note that this can't be done through the stock management interface, but could be done easily in "file-system" Python).
