Xen Project Style Guide

Updated June 13, 2014

The Linux Foundation owns the "Xen Project" trademark. Citrix still owns the "Xen" trademark and uses it for many variations of their products.

The following are basic rules that are important in protecting trademarks and service marks. These rules should be followed in all news releases, web site, presentation and marketing collateral.

Use Marks As Adjectives - Not As Nouns

Trademarks are adjectives that modify a generic noun. If you remove the mark and the sentence still works, it is probably being used correctly. Using a mark as an adjective is simple -- simply have the common descriptive name (noun) of the product or service follow the mark. This should be done throughout all material, not just on first reference.

Example of correct trademark usage: Buy TIDE detergent for whiter clothes.
Example of incorrect trademark usage: Buy TIDE for whiter clothes.

Correct: Download the Xen Project hypervisor.
Incorrect: Download the Xen hypervisor.
Correct: We use Xen Project software.
Incorrect: The Xen Project produces software. ("Xen Project" is being used as a noun).

Using a mark as an adjective is important because you do not want your mark to become the generic name for the product, like aspirin, escalator, thermos, and countless others.

Do Not Use Marks In The Possessive

Because trademarks are not nouns, they should not be used in the possessive.

Correct: The Xen Project leaders...
Incorrect: Xen Project’s leaders

Correct Project and Sub-Project Names

Correct References to Products and Versions:

Xen Project Hypervisor 4.4
Xen Project Mirage OS 1.0
Xen Project XAPI Toolstack 2.0

Recommended short-cuts, where the context allows are:

Hypervisor 4.4
Mirage OS 1.0
XAPI Toolstack 2.0
XAPI Project 2.0

Correct references to the ecosystem:

Xen Project community
Xen Project ecosystem
Xen Project Collaborative Project

Correct references to governance:

Xen Project Advisory Board
Xen Project Technical Coordination Team
Xen Project Governance

Correct references to teams in the project:

Xen Project sub-projects
Xen Project team<
Xen Project contributors
Xen Project developers
Xen Project users

Correct references to the technology:

Xen Project Virtualization
Xen Project Hypervisor
Xen Project ARM Hypervisor
Xen Project (Virtualization) Technology
Xen Project (Virtualization) Platform
Xen Project PV drivers
Xen Project software

Incorrect Usage examples:

Xen 4.4
Xen on ARM
Xen Mirage OS
Xen sub-projects
Xen hypervisor

Recommended short-cuts, where the context allows are:

ARM Hypervisor

Suggested Usage

Using the new style guide rules, we revised sample web site copy for a trial run with the new wording. We’ve also developed a new introduction for news releases.

Suggested News Release Intro:

Xen Project Virtualization Technology Powers the Largest Clouds in Production

The Xen Project Hypervisor is the leading open source virtualization platform powering some of the largest clouds in production today. Amazon Web Services, Rackspace Public Cloud and Verizon Cloud and many hosting services use Xen Project software.

Through years of development and deployment in the most demanding enterprise environments, Xen Project Software maturity and stability is second to none. It is the basis for many commercial server virtualization, desktop and embedded products as well as hardware appliances.

Xen Project Software is the Foundation for Many Products and Platforms: Developed 11 years ago, the Xen Project software’s maturity and stability is second to none. Xen Project Software is the basis for many commercial server virtualization, desktop and embedded products as well as hardware appliances. Netscaler and GlobalLogic’s Nautilus Platform. The Xen Project Hypervisor is also delivered as part of most Linux distributions as well as NetBSD.

Export Control

The Xen Project makes NO WARRANTY or representation that the information contained in the export control classification is accurate, current, or complete. It is your obligation as the exporter to comply with the current applicable requirements of United States export rules and regulations.  Any use of the information below is without recourse to The Xen Project and is at your own risk. The Xen Project is in no way responsible for any damages, whether direct, consequential, incidental, or otherwise, suffered by you as a result of using or relying upon such information for any purpose.

Source code and projects hosted by The Xen Project are classified with an Export Control Classification Number (ECCN) if it is believed to correspond to an entry in the Commerce Control List (CCL) and subject to the EAR. All Xen Project software is published in a publicly available source code form.  Publicly available software is only subject to the EAR when it is classified as ECCN 5D002 or 5D992.

Where not stated otherwise on the download page, products are classified as ECCN 5D002, and exported by The Xen Project under the TSU exception in EAR 740.13(e), which applies to software containing or designed for use with encryption software that is publicly available as open source. Exception TSU further provides that "Posting encryption source code and corresponding object code on the Internet (e.g., FTP or World Wide Web site) where it may be downloaded by anyone neither establishes "knowledge" of a prohibited export or reexport for purposes of this paragraph, nor triggers any "red flags" necessitating the affirmative duty to inquire[...]". Note that exporters other than The Xen Project within the US may or may not be eligable for exception TSU, and it is each specific exporter's responsibility to understand and comply with all export regulations applicable within their jurisdiction.
