<br>
Referring to <a href="https://trac.osgeo.org/osgeolive/ticket/1881" rel="noreferrer" target="_blank">https://trac.osgeo.org/osgeolive/ticket/1881</a>, I'm proposing <br>
adding t-rex to OSGeo Live.<br>
<br>
Description:<br>
<br>
- What is its name?<br>
<br>
t-rex<br>
<br>
- What is the home page URL?<br>
<br>
<a href="https://t-rex.tileserver.ch/" rel="noreferrer" target="_blank">https://t-rex.tileserver.ch/</a><br>
<br>
- Which OSI approved Open Source Licence is used?<br>
<br>
MIT<br>
<br>
- What does the application do and how does it add value to the <br>
GeoSpatial? stack of software?<br>
<br>
t-rex is a standalone vector tile server supporting PostGIS and GDAL <br>
datasources.<br>
<br>
- Does the application make use of OGC standards? Which versions of the <br>
standards? Client or server? You may wish to add comments about how <br>
standards are used.<br>
<br>
t-rex supports OGC simple feature data (plus ISO curves) and vector tile <br>
output in OGC WMTS compatible grids.<br>
<br>
- What language is it written in?<br>
<br>
Rust (<a href="https://www.rust-lang.org/" rel="noreferrer" target="_blank">https://www.rust-lang.org/</a>)<br>
<br>
- Which version of the application should be included in the next <br>
OSGeo-Live release?<br>
<br>
0.9.0<br>
<br>
<br>
Stability:<br>
<br>
- If risk adverse organisations have deployed your application into <br>
production, it would imply that these organisations have verified the <br>
stability of your software. Has the application been rolled out to <br>
production into risk (ideally risk adverse) organisations? Please <br>
mention some of these organisations?<br>
<br>
Known users are a national ornithological institute, real estate <br>
companies and public transport organisations. There was user feedback at <br>
FOSS4G conferences from national cadastral and mapping authorities about <br>
their use of t-rex for creating vector tiles.<br>
<br>
- Open HUB provides metrics to help assess the health of a project. Eg: <br>
<a href="http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html" rel="noreferrer" target="_blank">http://adhoc.osgeo.osuosl.org/livedvd/docs/en/metrics.html</a> Could you <br>
please ensure that your project is registered with Open HUB, and Open <br>
HUB has been updated to reference the correct code repository(s) for <br>
your project. What is the Open HUB URL for your project?<br>
<br>
<a href="https://www.openhub.net/p/t-rex-tileserver" rel="noreferrer" target="_blank">https://www.openhub.net/p/t-rex-tileserver</a><br>
<br>
- What is the size of the user community? You can often answer this by <br>
mentioning downloads, or describing a healthy, busy email list?<br>
<br>
Download statistics: <br>
<a href="https://www.somsubhra.com/github-release-stats/?username=t-rex-tileserver&repository=t-rex" rel="noreferrer" target="_blank">https://www.somsubhra.com/github-release-stats/?username=t-rex-tileserver&repository=t-rex</a><br>
Total Downloads: 1,440 - 278 <a href="http://hub.docker.com" rel="noreferrer" target="_blank">hub.docker.com</a> pulls.<br>
Communication is currently limited to Github and personal feedback to <br>
presentations at conferences.<br>
<br>
- What is the size of your developer community?<br>
<br>
Main application: 1 main committer, 8 code contributors<br>
Web-UI: 2 main committers<br>
rust-postgis: 2 main committers, 4 code contributors<br>
rust-gdal: 2 main committers, 9 code contributors<br>
<br>
- Do you have a bug free, stable release?<br>
<br>
Releases since 0.6.0 are considered production ready.<br>
<br>
- Please discuss the level of testing that your project has gone through.<br>
<br>
There is a built-in test suite which is automatically executed on Travis CI.<br>
<br>
- How long has the project has had mature code.<br>
<br>
The first public release was 2016-08-17 and version 0.6.0, which is <br>
considered production ready, was released 2016-11-07.<br>
<br>
<br>
- OSGeo-Live is targeted at applications that people can use rather than <br>
libraries. Does the application have a user interface (possibly a <br>
command line interface) that a user can interact with? (We do make an <br>
exception for Incubated OSGeo Libraries, and will include Project <br>
Overviews for these libraries, even if they don't have a user interface.)<br>
<br>
t-rex is an application with a command line interface and a built-in <br>
web-based user interface.<br>
<br>
<br>
- We give preference to OSGeo Incubated Projects, or Projects which are <br>
presented at FOSS4G conferences. If your project is involved in OSGeo <br>
Incubation, or has been selected to be presented at FOSS4G, then please <br>
mention it.<br>
<br>
There were t-rex specific FOSS4G presentations and vector tile <br>
presentations covering t-rex among others.<br>
<br>
<br>
- With around 50 applications installed on OSGeo-Live, us core packagers <br>
do not have the time to liaise with every single project email list for <br>
each OSGeo-Live release. So we require a volunteer (or two) to take <br>
responsibility for liaising between OSGeo-Live and the project's <br>
communities. This volunteer will be responsible for ensuring the install <br>
scripts and English documentation are updated by someone for each <br>
OSGeo-Live release. Also test that the installed application and <br>
Quickstart documentation works as expected on release candidate releases <br>
of OSGeo-Live. Who will act as the project's liaison person.<br>
<br>

<br>
- OSGeo-Live is Ubuntu Linux based. Our installation preference is:<br>
Install from UbuntuGIS or DebianGIS<br>
Install .deb files from a PPA<br>
Write a custom install script<br>
<br>
Deb Package for Ubuntu is available.<br>
<br>
<br>
Installation:<br>
<br>
- OSGeo-Live is memory and disk constrained. Can the application run in <br>
512 Meg of RAM?<br>
<br>
Yes.<br>
<br>
- How much disk space will be required to install the application and a <br>
suitable example application?<br>
<br>
~13MB for application binary<br>
<br>
<br>
- We aim to reduce disk space by having all applications make use of a <br>
common dataset. We encourage applications to make use of the example <br>
datasets already installed: <br>
<a href="http://wiki.osgeo.org/wiki/Live_GIS_Add_Project#Example_Datasets" rel="noreferrer" target="_blank">http://wiki.osgeo.org/wiki/Live_GIS_Add_Project#Example_Datasets</a> If <br>
another dataset would be more appropriate, please discuss here. Is it <br>
appropriate, to remove existing demo datasets which may already be <br>
included in the standard release.<br>
<br>
Examples are based on Natural Earth dataset.<br>
<br>
- Each OSGeo-Live application requires a Project Overview available <br>
under a CC By and a Quickstart available under a CC By-SA license. <br>
(You may release under a second license as well). Will you produce this?<br>
<br>
Yes.<br>
<br>
- In past releases, we have included Windows and Mac installers for some <br>
applications. It is likely we won't have space for these in future <br>
releases. However, if there is room, would you be wishing to include <br>
Windows and/or Mac installers?<br>
<br>
A Windows installer (MSI) is available. For Mac there is a binary only.<br>
<br>
