Hi All,

If I were to implement logic, so that GWC re-seeded a layer only for tiles which are within list of polygons which is defined in a geoRSS file, where would I start for implementing that logic?

Many thanks,

Steve

I think what you want may already be implemented?

http://geowebcache.org/docs/current/configuration/layers/georss.html

It could use more examples of making the GeoRSS feed perhaps. Have you tried it? Or is there more functionality you’re imagining? I think maybe reseeding doesn’t work super well?

To add to what Chris said, just beware this is the format for the feed
GWC understands:
<https://github.com/GeoWebCache/geowebcache/blob/master/geowebcache/georss/src/test/resources/org/geowebcache/georss/test-data/mixedgeometries_feed.xml&gt;

You'll need to code it, and upon geometry updates, make sure to
include an entry for the old geometry and another one for the new one,
so that gwc truncates based on the whole change.

In the future GeoServer will have a GeoSynchronization Service and
hope a GWC client comes along.

cheers,
Gabriel

Hi people!!!, we are progressing on spatialite wfs output format :wink:
WFS output format is working and generating spatialite database file (for now we keep it only on community/spatialite folder, but we have tested it adding files on wfs project folder and running it).
Now we are working on JAR files generation to wrap native libraries (for each OS + arch platform).
So....hopefully during next week we should have it finished with tests included. :slight_smile:

We will keep community updated.
Enjoy weekend !!!

Hi Jose,

Nice work. I notice from your last commit that a number of the files from the spatialite datastore were copied into the extension. Actually it looks like pretty much the whole datastore. Can you explain why this is done and why the geotools datastore is not being used directly?

If changes are needed to the spatialite datastore a better approach would be to submit patches and patch them directly at the geotools level.
