It Works!

It works! Once you get the app-schema extension installed and the tutorial data in place, it works just fine. Make sure that in your GetFeature requests you specify the outputFormat as GML3, as it won't work at all in GML2 (which GeoServer defaults to if no outputFormat is specified).

Also, be aware that the app-schema extension is only supported at WFS version 1.1.0.

Now I can move on to beginning to map my data into GeoSciML features. I'll write some more walkthrough as I put it together.

GeoServer: Installing the App-Schema Extension

I've been spending the last couple of days working with GeoServer version 2.0-beta2, which introduces the ability to serve complex features. Serving complex features is a critical component of providing geologic data in GeoSciML format.

GeoServer accomplishes this through the use of what's called the "app-schema" extension. Unfortunately, there is not yet a user-interface for configuring the extension, and so you set up your complex features manually, by creating folders and configuration files in the right places that say the right things.

Complex Features in GeoServer

GeoServer has released a 2nd Beta of version 2.0. You can read about it on their blog.

This is exciting because they've introduced what they're calling the "app-schema extension". Essentially, it represents real support for complex features. This will open the door to GeoSciML delivery through the friendly GeoServer interface.

Getting Started

I'm starting the process of implementing a WFS that delivers GeoSciML data. I intend to make Group Posts here detailing what I'm trying, what works, what doesn't, in the hopes that it wil both help me keep track of what I've done, and also be of use to someone else attempting to do something similar. If I find things that are of particular use, I'll end up making more formal walkthroughs. I'm coming at this without having much background in open-source software, OGC services or XML, so I'll have a lot to learn.
