[Zope-dev] RE: [Zope] Re: Workflow and document management system in Zope
hey Albert, In my opinion getting something like this together can not be done in less than 1 year. I'm familiar with workflow systems and very familiar with Zope. The projects you mentioned at the end of your letter are hardly of production value. You are looking at a major development undertaking. As far as EDM- its pure marketechture. A robust workflow management system that integrates into Zope is currently not available. You should determine exactly what you need, what is available, and go from there. There are many systems that say they are "workflow" and do entirely different things( Verve and Vitria are an example ). Again what you are doing is likely to be a major development undertaking. Good Luck! -josh zeidner I am looking for a workflow (WF) linked to a electronic document management (EDM) system and a groupware email based (I have just happened to come accross aethera from the Kompany) that would be free software and preferably in Zope + Python. The WF+DEM system I am looking for need to be usable with only a browser (to be independant from the client ... that could be proprietary !), store its data into a postgresql database. It should be demonstrablable (at least showable into a proof of concept) within 2 weeks and be already installable and usable within 2 or 3 months. (I have obtained taoday that the date when we'll decide on the system would be postponed 2 weeks from wednesday 24/1 to wed 7/2) If I could find such a marvel, I may find the money to pay for it, at least 5 $ to start with (this amount is a rapid guess; I may give more precise amounts we could spend in the following week) The idea is to use that combination of tools INSTEAD of buying a closed, proprietary solution (that may exist but be expensive and really har to parametrize), that NEED to be linked to a SAP ERP system. All suggestions and ideas are welcome, also on the selection criteria. (I happen to be responsible for the IT dept of the public institution that wants to buy such a tool, but be new in the place and do not yet know a lot about WF and EDM !) Soon I may be able to give you more details about the requirements. I don't think there is such as system polished and ready within 2 weeks. Here are some starting points: use wftk as a basis, the open source workflow toolkit -- http://.vivtek.com/wftk use openflow, a Zope based, but stalled project, http://openflow.sourceforge.net use Chautauqua, an old python based workflow system, http://www.cs.colorado.edu/~carlosm/chautauqua.html use the old UCI Endeavors workflow (java) system at http://www.ics.uci.edu/pub/endeavors/endeavors.html We have not bit the bullet and built anything yet.

RE: [Zope-dev] more on keyword indexes
OK. that clears a lot up. Im guessing that you can query all indexes that intersect with your query set( UNION ) by using the syntax Steve mentioned. ( or something like that ). as for the "unpredictable results", I found that querying the index produces different results every time I queried it. The steps to reproduce this are tedious and numerous. thanks, josh Josh Zeidner writes: > > However, Dieter says that it is not yet possible to > query for more than one keyword at once. At least, it was not my intention to say such a thing. You can search for several keywords at once, but the result is the *UNION* of the results for the single keywords. I.e., the keywords are combined with an "OR". You can not search for the objects with all the keywords you specify. I.e. you do not get the effect of ANDing your keywords.

Re: [Zope-dev] more on keyword indexes
Thanks for the reply.

OK. Is it possible to query keyword indexes for several keywords at once? If so, what is the syntax? Again, I am reporting a bug I have found that even if I am querying for only one( using the aformentioned syntax ), the results are unpredictable.

RE: [Zope-dev] keyword indexes
Hi Steve, Yes Im sure it is being indexed as I have set the MetaData as you described. It seems to be indexed as expected. Basically, what I am trying to do is set up keyword relationships so that I can present related links to the user( someone implied that this is the reason keywords were invented in the first place ). Are there any such examples on the web right now? -josh Josh Zeidner wrote: > Hi, > > Currently I am wrestling with "keyword" indexes in ZCatalogs.

The python MediaKeywords in ['ouch'] will be evaluated first, and will give a calue of 0 or 1. If MediaKeywords is a list, then it will always give 0, because there is only one item in ['ouch'], and that is the string 'ouch'. > What am I doing wrong? Is there a special ZCatalog function for querying > keyword indexes? I need some insight into this problem. Are you sure that the keywords are being indexed in your catalog? A good trick is to index the keyword attribute, and also store it as metadata. That way, you can look through your search results at the keywords the Catalog thinks you have. Also, check that you declared MediaKeywords as a keyword index, and that the MediaKeywords attribute in your objects is (or returns) a sequence type such as a tuple or a list. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ 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 )
[Zope-dev] more on keyword indexes
Hello, I did a little more investigiation into the problem, and couldnt really find any documentation anywhere on what the actual semantics are of keywords and how they are queried. For instance: I have three classes and each has an keyword index named KW: ObjectOne:KW = ['one','blue','furry'] ObjectTwo:KW = ['two','flying','purple'] ObjectThree: KW = ['three','one-eyed','purple'] If I were to query the ZCatalog with the following set of words: ['purple'] I would expect to get: ObjectTwo ObjectThree Right? If I query the database with ['one','two'] ( if this type of thing is at all possible ), I get : ObjectOne ObjectTwo This seems like the obvious result: BUT: it depends if you want a AND/OR type search. I could also expect to get nothing( if its an AND type search because no records match 'one' and 'two' ). Here is better example, what if I queried: ['purple','one-eyed']. Would I be expecting only ObjectThree or [ ObjectThree, ObjectTwo ] ( because they both match the keyword purple( a logical set-intersection ) ). Also I found the keyword indexes to have some more obvious bugs. If I only used one keyword for the matching critiria, for instance if I used 'purple' , I would only get ObjectTwo. Is anyone else using keyword indexes? In what way are you using them?

Re: [Zope-dev] The future of Zope with XML( what does ZDOM do for us? )
Hi Kevin, What FourThought/DC are currently doing with Zope will allow for fast transformations to memory-resident structured data( ZDOM or whatever ) to exportable XML documents( which are simply strings of characters ). This introduces( to the Zope world ) cutting edge metaphors in web-application design. All data to be served to a client is some form of XML: including HTML ( a better term: structured data ). The internal structure, or representation( or "deep structure" if you are into Chomsky ), is the data/knowledge as the web site managers see it- and most likely the most accurate and flexible when dealing with the particular information-domain( this is what theyre paid for :) ). Each user has custom needs- and wants to see this information the way they( or the applications working on thier behalf ) are accustomed to. So, architectually speaking, we need a way to easily and quickly construct XML documents from some meta-type( our internal structure ). This is what ZDOM is accomplishing for us. Parsing is a expensive endeavor. It is not practical to parse character streams every time we want to get at our data. So the solution is to represent the data as something more computationally digestible. Again : this is what ZDOM is accomplishing for us. Does this answer your question? have a good weekend, Josh Zeidner -"zippa-dee-doo-da" , uncle remus >Hello, > > Thanks for getting this document going.
