Setting up the Semantic Editor
The Semantic Editor makes use of several modules and libraries. Please install them in the given order, so that some preconfiguration can be done automatically.
Wysiwyg module and TinyMCE editor
First, you need to install the 3rd party Drupal module Wysiwyg. The Wysiwyg module allows for neat integration of several graphical text editors in Drupal. After enabling the Wysiwyg module, you will need to install TinyMCE. Please follow the installation instructions on Drupal. In order to check whether TinyMCE is installed correctly, go to its admin page on "Site Configuration" -> "Wysiwyg profiles". TinyMCE should appear with version information.
Note: Hiding the TinyMCE path bar does not work with Wysiwyg module (6.x-2.4) and TinyMCE 3.5. In WissKI editor, the path bar should generally be hidden, though, to avoid rendering issues. Please use the 3.4 branch of TinyMCE instead.
Textproc and Semantic Editor module
The Textproc module (on GitHub) is responsible for automatic text analysis and ontological modeling of text in WissKI.
The Semantic Editor module (on GitHub) enables the graphical text editor to make semantic annotations.
The wisski_text* module suite
This suite splits the functionality of the textproc module into separate modules. It supersedes the two older modules wisski_textproc and wisski_editor. See here for a short introduction to the modules.
Update: The infobox functionality has moved to the vocabulary control module. Although the editor module still includes the code for backwards compatibility, the vocab infobox should be used (this is the default now).
Search Entities module (optional)
The Search Entities module (on GitHub) is an add-on for the Semantic Editor. It provides a search dialog for quick search of entities that can be annotated. The module requires a newer version of jQuery than the one shipped with Drupal 6. Therefore, you also need the jQuery Update module.
