Xturtle is turtle editor solution based on eclipse / Xtext2. It features syntax highlighting, code completion (resource qnames, datatypes, language tags, literals, prefixe and namespaces URIs from prefix.cc), templates, syntax validation, internal linking to descriptions, preview of resources, navigation in outline and quick outline, folding (prefixes, subject blocks, multiline literals) and multiple customization options including syntax highlighting.

Installation

Starting from an existing eclipse installation, you first have to install Xtext, which is a dependency for Xturtle, from this update site:

http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/

After that, install Xturtle from this update site:

http://xturtle.aksw.org/site.xml

During the installation, you will get a warning that the package is unsigned.

You'll know that the editor is working, when you open a .ttl file and you are asked if you want to add the Xtext-Nature to the project. Further, on invoking code completion (ctrl-space) in the first line, something should happen...
