SOPE aims to be as compatible with WO 4.5 as possible, nevertheless some things are not available, some things work different, and of course a lot of additional things are available.

TODO: write much more ...

Note: Remember to look at the WO Compatibility Options page!

Things which WO 4.5 has, but SOPE doesn't have ...

• WebScript (work in progress - stay tuned!)
• Java support (shouldn't be difficult with JIGS!)
• DirectToWeb (shouldn't be difficult if GDL2 is ready, prototype of the rule engine is available in NGExtensions
• DirectToJavaClient

Things which are different in SOPE

• WOXML is available for Objective-C
• WOMessage XML DOM methods are available for Objective-C
• Builtin dynamic elements are class clusters for fast and small in-memory templates
• core dynamic elements in SOPE generate markup which works in both, XML/XHTML and HTML (eg <img /> instead of <img>)

Some special features of SOPE not available in WO

• components can act like direct actions! (TODO: write more)
• XML based templates (.WOx)
• "SOPE" aka DirectAction^3 aka Zope-style WO
• Various higher level reusable elements in WEExtensions (tableviews, treeviews, drag-n-drop, browsers, scheduling views, ...)
• builtin WebDAV implementation, including DASL
• builtin XML-RPC implementation
• DOM tree based rendering (NGObjDOM)
• Additional "hash" syntax in .wo wrapper templates (<#MyString/> instead of <WEBOBJECT NAME="MyString"></WEBOBJECT>)
• Supports a "cursor" in addition to the active component (incomplete, explain more)
• resource managers are bound to components
• always in direct connect mode
• SOPE:X, build WO apps as AppKit apps using WebKit
• ... TODO: add missing stuff

WOComponent

• -redirectToLocation: method (arg NSString or NSURL)
• supports WOx XML templates
• supports per-component resource-manager
• can act as a direct action (very cool!)
• has -existingSession method like WODirectAction
