Editing WebObjects (section)

==Open-source alternatives==
Interest in OpenSource alternatives to WebObjects that use the [[Objective-C]] language grew with WebObjects' move from Objective-C (last version WO 4.5.1) to Java (first version WO 5.0). The two frameworks available are SOPE,<ref name="sope">[http://sope.opengroupware.org/ SOPE Frameworks for Objective-C]</ref> which has been used as the basis of the [[OpenGroupware.org]] groupware server for about eight years, and [[GNUstepWeb]], which is part of the [[GNUstep]] project. Open-source rewrites of the EOF frameworks also exist (AJRDatabase, GDL2).<ref>[http://sourceforge.net/projects/ajrdatabase/ AJRDatabase]</ref><ref>[http://www.gnustep.org/experience/GDL2.html GDL2]</ref>

There are also Java-based alternatives:

* '''Wotonomy''' is a project, hosted on [[SourceForge]], that implements a clean-room, open-source version of the WebObjects 5.x system.<ref>[http://wotonomy.sourceforge.net/ Wotonomy Project]</ref> It provides a near-complete implementation of the MVC web-framework, as well as partial implementations of Foundation, Control, and Data layers, and other features. It is sufficiently functional for low-transaction volume, single-source database applications. While the project's structure was re-organized in 2006 around an [[Apache Maven]] build infrastructure<ref>[http://sourceforge.net/forum/forum.php?forum_id=541649 "Wotonomy moves to maven, removes non-free software"] - Christian Gruber</ref> and migrated to the [[Subversion (software)|Subversion]] [[revision control]] system,<ref>[http://sourceforge.net/forum/forum.php?forum_id=550278 "Wotonomy moves subversion"] - Christian Gruber</ref> there has not been any substantial update to the codebase since 2003.<ref>[http://sourceforge.net/forum/forum.php?forum_id=248937 "Wotonomy web is coming together"] - Micheal Powers</ref>

*'''[[Apache Tapestry]]''' has a design and philosophy similar to that of WebObjects.<ref>Tapestry In Action - Preface ({{ISBN|9781932394115}})</ref> Tapestry is frequently combined with [[Apache Cayenne]], a persistence framework inspired by [[Enterprise Objects Framework|EOF]].

* '''GETobjects''' is another framework<ref>[http://www.getobjects.org/ GETobjects]</ref> with an API similar to WebObjects 5.x that is related to SOPE.<ref name="sope" />

An attempt to do a [[Swift (programming language)|Swift]] version based on SOPE / GETobjects is available as SwiftObjects.<ref>[http://www.swiftobjects.org SwiftObjects]</ref> The implementation for Swift 4 is limited due to the reflection capabilities of that Swift version.
