This powerful object store provides seamless access ((through URLs. –Rich HTML.  Our documents add rich programming to HTML, including iteration, conditional testing, variable insertion, HTTP headers, cookies, and more.

 Powerful User Folders. –Users and passwords can be added to any URL level. –Sophisticated but simple sharing. –The Zope object system implements a breakthrough in object orientation called acquisition. This lets you share information along a URL, from higher up an organization to down below.

 Built-in objects. –Zope automatically provides useful objects for website builders. These include DMTL Methods, DTML Documents, Images,Folders,UserFolders, and MailHost objects. Additionally, there is a Control Panel that allows application and database management.  Application integration. –Zope provides tight integration with other products in the Zope line.

 Cross platform. –The Zope line has great reach and high performance across a number of operating systems and Web servers.

 Zope files and documents have a lot in common with conventional web pages –They have names, are arranged in hierarchies, and have URLs that correspond to their locations.  Folders contain other Zope objects.  The default object for a Folder is named index_html.  The Zope management screens allow you to navigate between folders and determine the URLs of objects.

 Images can display themselves and can also provide useful information such as size, title, and URL.  Get the contents of a Folder with the objectValues method.  Get the size of an Image with the getSize method.  Get the URL of an object with the absolute_url method.

 You can use forms to pass information between Zope objects.  You can programmatically create new Zope objects.  Zope documents can be the action of HTML forms.  The tag performs an action without inserting anything into a web page.  Create new images in folder with the manage_addImage method.

 You can use cookies to personalize a web page and dynamically control the presentation of a Zope document.  You can set cookies with the RESPONSE.setCookie method.  The tag allows you to test conditions.  The bobobase_modification_time method returns the last modification time of an object.
