[Geoserver-users] the output format GeoRSS

[abatany]

Hi all,

We would like to test the GeoRSS producted by Geoserver with Geowebcache in
order to control the tile expiration.

We use Geoserver (2.9) and a standalone Geowebcache (1.9) in order to
generate TMS.

In order to reseed only tiles that data have updates, we want to test
GeoRSS.

With the documentation of geowebcache
http://geowebcache.org/docs/current/configuration/layers/expiretiles.html#server-tile-expiration,
we have completed the file geowebcache.xml like this to test the tile
expiration:

/ <name>test_layer</name>
<gridSubsets>
<gridSubset>
<gridSetName>EPSG:900913</gridSetName>
<extent>
<coords>
<double>301614.5243302532</double>
<double>6492166.403268518</double>
<double>312616.500421026</double>
<double>6499620.031302505</double>
</coords>
</extent>
<minCachedLevel>12</minCachedLevel>
<maxCachedLevel>19</maxCachedLevel>
</gridSubset>
</gridSubsets>
<updateSources>
<geoRssFeed>

<feedUrl>http://localhost/geoserver/wms/reflect?layers=test_layer&amp;format=rss&amp;lastupdate=${lastUpdate}</feedUrl>
<gridSetId>EPSG:3857</gridSetId>
<pollInterval>600</pollInterval>
<operation>reseed</operation>
<format>image/png</format>
<seedingThreads>10</seedingThreads>
<maxMaskLevel>14</maxMaskLevel>
</geoRssFeed>
</updateSources>
<wmsUrl><string>http://localhost/geoserver/wms</string></wmsUrl>
</wmsLayer>/

But no tile is reseed after the data have been updated.
It seems that at the Geoserver GeoRSS output there is no <updated> field,
the field used by geowebcache.


Does anyone have experience with GeoRSS in Geoserver, and/or with automatic
reseeding of tiles after a call from geowebcache to geoserver?

Thanks,

Aurélie
