Is it production grade? Giovanni, I experienced similar problems trying to catalog =B7~200000 objects with ~500 MB text. Using CatalogAware objects will indeed lead to a "really fat" data base, and using the "find objects" for a ZCatalog requires considerable resources. A text index (more precise: the class UnTextIndex) works, as far as I understood it, this way: 1. The method UnTextIndex.index_object splits the text into single words, using the method [Globbing]Lexicon.Splitter. = 2. UnTextIndex.index_object looks up the wordID (an integer) of each word in the lexicon. If a word is not yet listed in the lexicon, it is added to the lexicon. = 3. All wordIDs are inserted into self._index, which maps wordIDs to the list of documents containing this word. 4. The "unindex" BTree , which maps the documentIds to the the list of all words appearing in an document is updated. If you are adding only one CatalogAware object during a transaction, this is quite expensive: Even if the indexed object contains only one new word, the entire lexicon needs to be updated. In my tests with the 200000 objects (containing ordinary German texts) the lexicon contained ~ 1 million words. (BTW, I had not had a very close look into the contents of the lexicon, so I don't know yet exactly, why it is so large. But I noticed quite many entries like "38-j=E4hrige", "42-j=E4hrig= e" ("NN-year-old") entries. So a configurable splitter method might help quite much to reduce the size of the lexicon.) Hence, the above mentioned step 2 alone can result in a really bloated data base. A solution might be a kind of "lazy catalog awareness": Instead of mangling a new object through one or more catalogs when it is created, this object could be added to a list of objects to be cataloged later. This way, the transaction to insert a new object would become much "cheaper". I'm working on this, but right now it is quite messy. (I'm new to Python and Zope, and hence I'm stumbling over a few, hmmm, trip-wires...) But even using such a "lazy catalog awareness", you might get into trouble. Using the ZCatalog's "find objects" function, I hit the limits of my Linux box: 640 MB RAM were not enough... As I see it, the main problem is that UnTextIndex.index_object tries to do all work at once: Updating the lexicon _and_ self._index _and_ self._unindex So I tried to separate these tasks by writing the data to be stored in self._index (wordId, documentId, score) into a pipe. This pipe is connected to sort(1). After all objects have been "scanned", the pipe is closed, the sorted results are read back and self._index is updated. This way, Zope needed "only", uuhh, somewhat aroud 200 or 300 MB RAM. A few weeks ago, I've posted this (admittedly not fully cooked) patch to this list, but did not get yet any response.

And I guess that 10-20% of that 40% are again invested for marketing from companies like IBM or MS. So the VAR knows he doesn't really lose all the money he pays for the software, instead it's used to generate marketing pressure and other goodies (take Chris' "IBM certified for e-Business" example). They get nice developer conventions and other things, all of that is done to suggest a spirit of success and to show a common goal. All in all it might not be _that_ easy to persuade VARs to use OSS. > The customer doesn't realize: > 1) That open source makes that argument largely irrelevant. > But we don't really have the marketing muscle to fight this > battle, at least where it needs to be fought. > 2) That there are hundreds of consultants familiar with Zope/[insert > other open source solution here] that can take over that 100% > when the one who sold it to you goes out of business.

These two point are IMO only sufficient to get a tie in the battle zope vs [proprietary offering from MS/IBM] - if any, because for every zope consultant there are 100 (or 1000) notes/asp etc. consultants. > Grassroots, "line-level" employee support is most of the support that > open source has got, and that's its marketing engine.

I think one has to differ the types of potential clients, and they are not always recognizable by the size of their company. 1. Nearly no technical knowledge, don't know words like "application server", know names like IBM or Microsoft, but only MS is more familiar because they use their desktop OS and office applications. Their motivation is to either a) Get their first web-presence b) Revamp their existing (static) web-presence because they think its to ugly and/or they want to get new functionality like putting in content by themselves. 2. Some IT knowledge, they have already a web-presence but got burned (their agency charges the big bucks for just changing telephone numbers), and are critical because of that. 3. Good IT knowledge, are able to do a lot by themselves, often just lack the time or design capabilities to do their own web presence. Only types 2 and 3 will question the choice of the underlying plattform. And it's often not the decision makers who will do that, but the IT personnel. And it helps a lot to first try to gain ground with the decision makers, because an open minded (because his boss told him to be open minded) IT expert can really be persuaded to see zope's strength. This gets me to the point of my drivel: What do others think of the idea of a glossy brochure (like 4 pages) which can be used as a handout about zope for decision makers? Nothing academic, just pure marketing speak. Heavy on buzzwords, short on (technical) information, but nice to look at. It should be downloadable from zope.org as a photoshop document, with layers etc. fully intact. Perhaps with some blank space (one page), so that everyone could include company specific information, perhaps not. Then everyone who wants to could just use that to produce zope-specific marketing material. Mind you, I don't want to say that DC should produce that, I guess more people in this list have graphic designers in their company. cheers, oliver

ZPT: ready for prime time?

Hello Zopistas, we are before a big redesign of our Zope Site http://www.european-e-business.com The complete Look&Feel will be changed and we will switch from the Zope oldie 2.1.6 to the latest Zope version. The GUI will be developed with DreamWeaver. We are currently facing the following decision: * do we use ZPT/XHTML for presentation or * do we stick with the familiar DTML The designer told us, he (and his tool) can handle both. Thus, it boilds down to: ZPT/XHTML DTML modern approach in the future, probably only investment in the future used in niches in flux, probably unstable stable, we know its strengthes/weaknesses maybe, missing features (e.g. batching) poor documentation quite well documented by now e.g. loop variables, TALES variables What are your experiences? What do you think? Dieter
