Is there any way in Zope to validate information (news, new document) by third party before real publishing. For example some people are alowed to put a document in the folder but these documents must be validate by some one else for real publishing. How can I do this kind of things with Zope? Is it possible? Any suggestion? links? help? [RH] There are several ways to accomplish this: You could put the document in an 'incoming' folder and make a reviewer move it to the publishing location (this also allows for letting the reviewer add keywords/categories etc). If the uploaded document goes directly to the documentation where it is published, you could give it a property called 'approved'; reviewer invokes dtml method which sets the approved property to 1. The document is not shown unless the ' approved' == 1. [untested simplistic dtml] <dtml-unless "approved==0"> <dtml-var <document>> </dtml-unless> I believe the Squishdot product (http://www.zope.org/Members/butchland/Squishdot) allows for something like this. A third (more sophisticated) possibility is to combine the two approaches by using the Catalog, more or less like the Zope site does: contributions by members are submitted for approval to the Zope site administrators, who then add them to the site's catalog. Then they are available in pages that use the catalog for their contents (like the howto pages, the products pages etc). In your case reviewers could also add keywords/categories etc to the document before it is cataloged and the catalog may index these. I do not think the Zope site approach is available for the public, but it shouldn't be too difficult to implement it. A related product is ZDP tools (http://www.zope.org/Members/roeder), which does not exactly do this but may be a source of inspiration for workflow management. Another workflow system in Zope is Xen (I do not have the URL handy right now), but this may be overkill for your needs. hth Rik
