Hi, I’m answering the questions referring to both versions. 
If you consider including Java and Web version, I will provide two different installation scripts.  
I confirm that my contributions to OSGeo-Live will be compatible with the OSGeo-Live license guidelines at the time of contribution

-What is its name?
Nasa World Wind, composed of Go World Wind and Web World Wind

- What is the home page URL?
http://goworldwind.org/ and http://webworldwind.org/ 

-Which OSI approved Open Source Licence is used?
NASA OPEN SOURCE AGREEMENT VERSION 1.3 (https://opensource.org/licenses/NASA-1.3)

-What does the application do and how does it add value to the GeoSpatial stack of software?
World Wind provides a rich set of features for displaying and interacting with geographic data and representing a wide range of geometric objects using a 3d virtual globe

-Does the application make use of OGC standards? Which versions of the standards? Client or server? You may wish to add comments about how standards are used.
Yes, it uses on the client WMS, WFS and as GIS formats: Shapefile, KML, VPF, GML, GeoJSON, GeoRSS, GPX, NMEA and many others to draw services on the globe

-What language is it written in?
The Java version (goworldwind) is written mostly in java and C++, while Web version is in Javascript

-Which version of the application should be included in the next OSGeo-Live release?
World Wind Java SDK 2.0.0 and regarding the web version, it’s updated frequently, so the latest one available during the disk build process.

- If risk adverse organisations have deployed your application into production, it would imply that these organisations have verified the stability of your software. Has the application been rolled out to production into risk (ideally risk adverse) organisations? Please mention some of these organisations?
US Federal Aviation Agency (FAA), US Department of Energy, US Air Force, Army and Navy, US State Department, US Geological Survey, European Space Agency, Politecnico di Milano at Como, Sweden Defence Research Agency (FOI)

-What is the Open HUB URL for your project?
https://www.openhub.net/p/wwj and https://www.openhub.net/p/WebWorldWind

-What is the size of the user community? You can often answer this by mentioning downloads, or describing a healthy, busy email list?
The US Government is our largest ‘formally recognized’ community, with well over a 100,000 users. World Wind apps are a standard in multiple US agencies. Additionally, the European Space Agency has standardized on WebWorldWind for delivery of spatial data. The  www.WorldWindCentral.com forum has: Threads: 13,095;  Posts: 73,902; Members: 32,080; Active Members: 90

-What is the size of your developer community?
Because applications using World Wind are many, especially throughout the US Government, we cannot confirm the actual size of that community but it is estimated to be in the hundreds.

-Do you have a bug free, stable release?
Yes, the latest stable version, 2.0.0 for the Java and the last in the website for the Web’s one.

-Please discuss the level of testing that your project has gone through.
All versions of World Wind are tested before each release. Additionally, feedback via the forum contribute to identification of issues found by the open source community and these are addressed accordingly.

-How long has the project has had mature code.
World Wind began as a .NET app in 2003 with some days in 2004 at SourceForge (http://sourceforge.net/projects/nasa-exp/) of almost 100,000 downloads a day at ~250MB (including a base set of imagery and elevation data for the world, the application was only a small fraction of that). The Java version has been mature since late 200, the iOS version since 2014 and the web version continues to mature, but has been standardized on for use by the European Space Agency.

OSGeo-Live is targeted at applications that people can use rather than libraries. Does the application have a user interface (possibly a command line interface) that a user can interact with? (We do make an exception for Incubated OSGeo Libraries, and will include Project Overviews for these libraries, even if they don't have a user interface.)
Yes, in both version it has a user interface to interact with the globe, even though its main purpose is aimed to develop new applications. It includes a lot of examples (with the proper source code) to test all the features using a graphical user interface.

-We give preference to OSGeo Incubated Projects, or Projects which are presented at FOSS4G conferences. If your project is involved in OSGeo Incubation, or has been selected to be presented at FOSS4G, then please mention it.
It was presented on different FOSS4Gs and is also in the OSGeo wish list

- Who will act as the project's liaison person.
Gabriele Prestifilippo

-Can you please discuss how your application will be installed.
About the installation for both versions, it will use a custom script, which downloads the files, and then copies them into a directory, from which is possible to find samples and executables.

-OSGeo-Live is memory and disk constrained. Can the application run in 512 Meg of RAM?

-How much disk space will be required to install the application and a suitable example application?
The java version occupies around 300mb with samples, but might be possible to reduce the size removing some files (documentation ~130mb ). While less than 20mb the Web version

- Each OSGeo-Live application requires a Project Overview available under a CC By and a Quickstart available under a CC By-SA license. (You may release under a second license as well). Will you produce this?

-In past releases, we have included Windows and Mac installers for some applications. It is likely we won't have space for these in future releases. However, if there is room, would you be wishing to include Windows and/or Mac installers?

Hi Gabriele,

Thank you for picking up this task.

For the install script, can you please provide a pull request here:
Proposed script name: install_worldwind.sh

Also, you can issue a pull request for the documentation here:

In order to accept the pull requests, you will need to confirm that you will comply with our license guidelines:

Hi Gabriele,
Great to hear from you and interest in seeing NASA WorldWind on OSGeo-Live.

The first step in including a project is to send an email to this list addressing the questions linked from:

This helps us determine whether a project is a good fit for OSGeo-Live, and also consider any logistical issues which we might face (such as if there is enough space).

I'm looking forward to working with you further on this.

Warm regards,

Cameron (one of the OSGeo-Live coordinators)

Dear all, 
I'm writing here on behalf of Patrick Hogan's suggestion, to propose the inclusion of NASA World Wind in the next OSGeo release (http://goworldwind.org/ and http://webworldwind.org/). 
I've been asked to fulfill the requirements from the Wiki, and I created the scripts for the project and prepared the documentations. 
Let me know what else is needed to proceed.
Best regards, 
Gabriele Prestifilippo
