[Geoserver-devel] HANA as a downloadable vector format extension

GeoServer GeoServer Developer

Hi all,

I’m the maintainer of GeoTools‘ JDBC HANA Plugin (https://docs.geotools.org/latest/userguide/library/jdbc/hana.html). It was promoted to a supported module recently and I’d like to add it to GeoServer as a downloadable vector format extension. Is that ok with you?

Assuming you are fine with it, is there something I have to pay attention to? As far as I can tell I don’t have to touch Java code, but need to add/modify some POM files only and add proper documentation. Is there something else that has to be done?

Thanks and best regards,

Stefan

In GeoServer extensions have a set of requirements. A pure datastore without actual code in GeoServer cannot match them all, but you
can see a proposal for a full graduation here:
https://github.com/geoserver/geoserver/wiki/GSIP-170

In your case, I believe we need at least:

  • Active maintainer with signed CLA (you?)
  • Documentation
  • Handful of users (at least 3): can you report some?
    Cheers

Andrea

Hi Andrea,

Thanks for your prompt reply.

I just realized that GeoServer distinguishes between community modules and extensions. It’s also fine to start as a community module. Most important for us is that the instructions how to use GeoServer with HANA are included in GeoServer’s documentation. Currently, we only have a blog article (https://blogs.sap.com/2019/03/28/how-to-connect-sap-hana-with-geoserver/), and keeping that up-to-date with GeoServer releases is cumbersome.

The maintainer would be me.

So, if my understanding is correct, I could start adding the datastore as community module with all the required documentation. Later on, the PSC could vote on promoting the module to extension.

With regards to the users: Do you already need that info for community modules? What info do you need exactly? I guess I can’t just disclose customer names without asking for permission. Unfortunately, I usually don’t have direct contact to customers. SAP is a rather large company, and our department is usually contacted by presales colleagues who were asked for GeoServer support by customers…

Best regards,

Stefan

Yes. The only annoying bit for you, going community module, is that the package won’t be available for releases,
but only among nightly build downloads, e.g.:
https://build.geoserver.org/geoserver/2.15.x/community-latest/

https://build.geoserver.org/geoserver/master/community-latest/

With regards to the users: Do you already need that info for community modules? What info do you need exactly?

For a community module, none. For an extension, an indication of how many users are using it in production (we’ll trust you, if you can share some details better).

Cheers
Andrea
