Dear all,
I’ve been talking with Patrick, and we agreed on versioning with a tagged release WebWorldWind, although this cannot be achieved for technical reasons before few weeks at least. I clearly understand that having a tagged release is useful for different reasons.
Since at the moment we cannot officially define it, I would suggest to mark it as ‘pre-release’ or even 0.1.0 but not formally until they can mark it. I still support the inclusion because, as I previously mentioned the web version is the one with the greatest expectation and a wider future.
Let me know what you think about it, or if you have other ideas regarding it. Unless we could wait for the next release to include it.
Best,
Gabriele.

Gabriele, how about a 0.x release number, until there is a feature complete 1.0 release?

Ok,
I'll rephase "requirement" to "strongly request the version of World Wind Web installed on OSGeo-Live be allocated a version number", for the reasons listed below.
Gabriele, do you think this is achievable?
I think I'm safe in saying that using version numbers is in line with best practice software engineering, and one of the indications of project maturity we wish to encourage.
Cheers, Cameron

Hi Cameron,
Given that we include at least another project that uses "trunk" (for many years now) and not a released version, we cannot make this a hard requirement in my opinion

Hi Gabriele,
Thanks for offering to help with reducing packaging size. That will be helpful.
I also think it would be very valuable for the version of the World Wind Web to be installed on OSGeo-Live to be allocated a version number. There are many reasons for this, including:
1. People will be able to determine if the version of World Wind Web they are looking at is the latest version.
2. People will be able to determine if they should upgrade to a more recent version (because they are looking at an older version)
3. Developers and users will be able to align feature lists and bug reports with specific version numbers, which will help users determine whether to upgrade
I think that defining a package version number should be a prerequisite for including the package on OSGeo-Live. The version number could be called "beta" so long as it is considered "stable" by the developer and user community.
Warm regards, Cameron

Hi,
the Java version and the JavaScript’s one, are two different applications, so we need to separate them.
I understand that the size of the Java might be a problem. I can try to work a bit on it and delete the not strictly necessary files from the original package, so to achieve a reasonable size.
Regarding the web version, I may ask Patrick about a tagged release, even if now it seems to appear as ‘pre-release’ version.
Even though I want to reassure you that in spite of being not even a beta, its usage was growing consistently in the past two years (as you may see from the different projects developed), and no bugs were reported. It is tagged in this way because not all the features available in the Java version are yet available.
Best,
Gabriele.

Thank you Gabriele for the detailed responses.
I also strongly support the inclusion of Nasa World Wind in OSGeoLive.
Regarding the size of the installation, I would like to try a basic installation first (without documentation to save some space) so we can find out how much World Wind will compress in the iso. The next step would be to try to use the data already present in the disk. Then we will be able to make a decision regarding the amount of sample data that will be needed.
Regarding Java vs Web version, personally I would like to see both included.
Having a tagged release is a good sign of stability, so I would prefer to have a tagged version included. This would also help potential packaging efforts.
Best,
Angelos

Thanks Gabriele,
Based on your responses, it seems that Go World Wind is a mature, established open source GIS product, which is in line with the principles of OSGeo Live.
On the downsite, it appears to be a large product, which may be a challenge to fit on OSGeo-Live. I'd be interested to hear thoughts from Angelos and others in that regard.
The documentation does appear to be comprehensive and I feel shouldn't be included with the OSGeo-Live release (it can be referenced). Instead just provide standard OSGeo-Live Project Overview and Quickstart.
Also, I request you make use of existing OSGeo-Live sample data rather that adding a new dataset. This reduces disk space and helps with comparisons and integration between applications.

I'm undecided on whether World Wind Web is ready. I'd be hoping to see a specific stable version nominated for inclusion.
It also seems to have a relatively new development history, so might not have reached a stable release yet?
Would it make to bundle GeoWorldWind and WorldWindWeb together? Or are they two stand alone applications?
Warm regards, Cameron

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?
Yes
-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?
Yes
-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?
Yes
Best,
Gabriele

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:
https://wiki.osgeo.org/wiki/Live_GIS_Disc#How_to_add_a_project_to_OSGeoLive
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
