User commentary
Please sign all comments.

I have found this program to be affordable, easy to use, and pre-loaded with TEI capabilities. Also, the platform gets upgraded on a regular basis. -- Greg Moses (Austin, TeiXas!)

System requirements
Runs under Windows, Linux, and Mac operating systems. Requires a Java VM (virtual machine).

(One of the download options for Windows users is an installer that includes the Java VM, eliminating the need to download and install Java separately.)

For detailed requirements, see http://www.oxygenxml.com/download.html.

Source code and licensing
Closed source. Academic licenses available for $48 per person, allowing you to install for your own use on many computers and use with the current major version number. A discount is available for TEI subscribers and individuals from TEI member institutions; the discount code may be found by logging in to http://members.tei-c.org/MemberInfo. Free 30-day trial license available.

The TEI Framework in &lt;oXygen&gt;
As of Version 9.0 build 2007110615, &lt;oXygen&gt; has TEI P5 schemas, templates and the TEI XSL stylesheets included as an officially-supported framework.

If you are not using the  Debian package (for which a package manager will provide automatic updates for new versions of the stylesheet library), you can upgrade your copy of the stylesheet library without needing to download a new version of &lt;oXygen/&gt; doing doing either of the following:


 * With version 15.2 or later of &lt;oXygen/&gt;, "subscribe" to the regularly-updated TEI distribution of the framework according to the instructions in this blog post: http://blogs.it.ox.ac.uk/jamesc/2014/04/02/auto-update-your-tei-framework-in-oxygen/.


 * Use oxygen-tei, the open-source TEI framework built into &lt;oXygen/&gt;. To install this, look in your Oxygen folder for a "frameworks" directory that contains a directory called "tei". That's where the contents of the zip would go, replacing the old contents of that directory. Note that this is not the same thing as the   Debian package! You can also build this framework for yourself if you are interested in doing so; the project code is available on GitHub.

Other TEI-related Plugins
&lt;oXygen/&gt; allows third-party plugins and frameworks. The following are of possible interest to TEI users:

HisTEI
If you work with historical documents, you might use HisTEI, a framework designed to make historical documents easier to transcribe in &lt;'s XML Author mode.

Severin
Severin is an image viewer plugin, by Kilian Schmidtner and Stefan Krause, that can be used to see images as you browse though documents. It is an open source project (MIT license), and on the project page you can find a video presentation that uses a TEI document as example.

TEI-Facsimile-Plugin
TEI-Facsimile-Plugin "provides support for working with Digital Facsimiles in Text Encoding Initiative (TEI) vocabulary. The plugin contributes a new View in which the user can load an image and draw shapes. These shapes are then converted into TEI "zone" elements. All the existing "zone" elements from the document are also rendered over the image." This plugin requires oXygen version 15 or later.

Additional notes
David Sewell wrote:

Because the schema files distributed with oXygen sometimes lag behind the latest TEI releases, kind souls like Syd Bauman have from time to time packaged new schema files so that they can be unpacked to replace part of the oXygen frameworks hierarchy. You could also go to

http://www.tei-c.org/release/xml/tei/custom/schema/relaxng/

and grab the files there to replace the ones in a local oXygen directory.

Sebastian Rahtz added that if you use Debian or Ubuntu, you should instead install the  package. He explained that "this replaces the oXygen TEI package with a link to one installed by the tei-p5-schema package, which is kept up to date. This means you have only one set of TEI files on your machine." It's available at http://tei.oucs.ox.ac.uk/teideb/.

Marcus Bingenheimer: If you edit ODD files you need to validate the ODD against tei_odds. tei_all will not catch all mistakes and gives and error whenever elements in the RNG or other namespaces are used within
