[Geoserver-devel] Yahoo Traffic

We need to make traffic data available as a WFS service. We have a web
service which gives us the traffic data. I'm working on writing a
geotools Datastore for the web service. From looking at the
documentation it sounds like I can relatively easily take a datastore
and add it to Geoserver as a datasource. I can't find anywhere though
that actually tells how to do that. How do I do this?

Also we're doing this for profit so we are concerned about the GPL
license. The following web page says we can get an alternate license:
http://docs.codehaus.org/display/GEOSDOC/Developer+Introduction

How do we go about doing that? Thanks.

Ok, just added a FAQ question to the docs for this, since I couldn't find a good answer in the docs: http://docs.codehaus.org/display/GEOSDOC/Adding+a+new+DataStore

Basically you just have to implement the right API, include a file that tells the right name, and then stick the jar on the classpath (or in geoserver/WEB-INF/lib).

We're working on making that available, we need to get appropriate contributors to sign off on it though. Note that if you're just setting up a service then there's nothing in the GPL that affects you, it's only when you distribute the code. GPL certainly lets you do things for profit, it's only in certain cases where it need really concern you.

best regards,

Chris

Drop the jar into your geoserver libs directory, GeoServer should pick it up automatically.

Well for your specific datastore everything is good as geotools is LGPL.

How do we go about doing that? Thanks.
  

For geoserver right now you can talk to TOPP and get permission. If you check out what is going on GeoServer 1.4.x
we are opening up other options for you to package with out copying, but some time will still need to be spent to ensure
that license issues are open enough for biz.
