<!-- template
string template that will be used to map a tile (by tileset, grid name, dimension,
format, x, y, and z) to a filename on the filesystem.
the following replacements are performed:
- {tileset} : the tileset name
- {grid} : the grid name
- {dim} : a string that concatenates the tile's dimension
- {ext} : the filename extension for the tile's image format
- {x},{y},{z} : the tile x,y,z values
- {inv_x}, {inv_y}, {inv_z} : inverted x,y,z values (inv_x = level->maxx - x - 1). This
is mainly used to support grids where one axis is inverted (e.g. the google schema)
and you want to create on offline cache.
* note that this type of cache does not support blank-tile detection and symlinking.
* warning: it is up to you to make sure that the template you chose creates a unique
filename for your given tilesets. e.g. do not omit the {grid} parameter if your
tilesets reference multiple grids. Failure to do so will result in filename
collisions !

<!-- tileset
a tileset regroups a <source>, <grid> and <cache>.
the "name" parameter is mandatory, and represents the key by which this tileset
will be requested by clients (e.g. in the WMS LAYERS parameter)
-->
<tileset name="test">
<!-- source: the "name" attribute of a preconfigured <source> -->
<source>vmap0</source>
<!-- cache: the "name" attribute of a preconfigured <cache> -->
<cache>sqlite</cache>
<!-- grid: the "name" attribute of a preconfigured <grid>
you can also use the following notation to limit the area that will be cached and served to clients:
<grid restricted_extent="-10 40 10 50">WGS84</grid>
this way is better than using a grid with a limited extent, as in this way the tiles that are already
cached are not invalidated should you want to modify the restricted extent in the future. When using
the restricted_extent attribute, you should give the corresponding information to the client that will
be using the service.
you can also limit the zoom levels that are cached/accessible by using the minzoom, maxzoom attributes.
NOTE: when adding a <grid> element, you *MUST* make sure that the source you have selected is able to
return images in the grid's srs.
-->
<grid restricted_extent="-10 40 10 50" minzoom="6" maxzoom="8">WGS84</grid>

<!-- metadata
optional metadata tags used for responding to GetCapabilities request.
you can put anything in here, although only the title, abstract and
keywords tags are currently used to populate the GetCapabilities
document.

<title>vmap0 map</title>
<abstract>blabla</abstract>
<keywords>
<keyword>foo</keyword>
<keyword>bar</keyword>
</keywords>
</metadata>
<!-- watermark
optional tag to add a watermark to the tiles *before* storing them to cache
the supplied image MUST be exactly the same size as the size of the tiles
configured in the <grid>
the supplied image is read when the configuration is loaded.
if you make changes to the image, they will NOT be reflected on tiles already
stored in the cache, nor on newly stored tiles until the server is restarted
<watermark>/home/tbonfort/dev/mod-mapcache/static/watermark.png</watermark>
-->
<!-- format
(optional) format to use when storing a tile. this should be a format with high
compression, e.g. png with compression "best", as the compression operation is only
done once at creation time.
if left out, no recompression is applied to the image, mod-mapcache will store the
exact image received from the <source>
note that the <format> tag is mandatory if metatile, metabuffer or watermark are
supplied, as in those cases a recompression has to be done.
-->
<format>PNG</format>
<!-- metatile
number of columns and rows to use for metatiling, see http://geowebcache.org/docs/current/concepts/metatiles.html
-->
<metatile>5 5</metatile>
<!-- metabuffer
area around the tile or metatile that will be cut off to prevent some edge artifacts.
if using this, the configured source must be instructed not to put any labels inside
this area, as otherwise this will result in truncated labels (for mapserver, this is
the "labelcache_map_edge_buffer" "-10" metadata entry, along with label PARTIALS FALSE
-->
<metabuffer>10</metabuffer>
<!-- expires
optional expiration value in seconds for a tile. this is expressed in a number of seconds
after the creation date of the tile
This is the value that will be set in the HTTP Expires and Cache-Control headers, and has
no effect on the actual expiration of tiles on the caches. See <auto_expire> for that.
-->
<expires>3600</expires>
<!-- auto_expire
automatically re-request tiles and update the cache once they are older than the given number
of seconds after their creation.
Note that this will only delete tiles form the cache when they are accessed, you cannot
use this configuration to limit the size of the created cache.
Note that if set, this value overrides the value given by <expires>
-->
<auto_expire>86400</auto_expire>
<!-- dimensions
optional dimensions that should be cached
the order of the <dimension> tags inside the <dimensions> is important as it is used
to create the directory structure for the disk cache. i.e. if you change the order of these
values, any tiles that have been previously cached are invalidated (but not removed from the
cache, it's just they don't exist anymore for mod-mapcache
-->
<dimensions>
<!-- values dimension
the example here creates a DIM1 dimension
* WMS and WMTS clients can now add a &DIM1=value to their request string. If they don't
specify this key/value, the default will be to use DIM1=foobar
* the allowed values for DIM1= are foobar (it is important to add the default value to the
allowed values entry), foobarbaz, foo and bar.
* the value specified for DIM1 will be forwarded to the WMS source
* the produced tile will be stored in base/gridname/DIM1/value/xx/xx/xx/xx/xx/xx.png
file. i.e. their are as many different caches created as their are values in the
<values> tag.
-->
<dimension type="values" name="DIM1" default="foobar">
<value>foobar</value>
<value>foobarbaz</value>
<value>foo</value>
<value>bar</value>
</dimension>
<!-- regex dimension
the following creates a MAPFILE dimension, for using the same mod-mapcache tileset with different
mapserver mapfiles. the name of the mapfiles need not be known to mod-mapcache, and can therefore be
created even after mod-mapcache has been started.
when a user passes a MAPFILE=/path/to/mapfile, the string "/path/to/mapfile" is validated against
the supplied (PCRE) regular expression. The one in this example allows a name composed of alphanumeric characters
separated by slashes (/) and finishing with ".map" ( [a-zA-Z0-9\./]*\.map$ ) , but will fail if there
are two consecutive dots (..) in the path, to prevent filesystem traversal ( (?!.*\.\.) ).
-->
<dimension type="regex" name="MAPFILE" default="/path/to/mapfile.map">
<regex>^(?!.*\.\.)[a-zA-Z0-9\./]*\.map$</regex>
</dimension>
<!-- intervals dimension
the syntax is the same as common-ows, i.e. a comma separated list of "min/max/resolution" entries.
eg:
* 0/5000/1000 allows the values 0,1000,2000,3000,4000 and 5000
* 0/100/0 allows any values between 0 and 100
* both values can be combined: 0/5000/1000,0/100/0
-->
<dimension name="ELEVATION" type="intervals" default="0">0/5000/1000</dimension>

<!-- default_format
format to use when a client asks for an image that is dynamically created from multiple
tiles from the cache.
note that using a png format with "best" compression is not recommended
here as it comes with a very compression overhead in terms of cpu processing. it is
recommended to use a png format with "fast"compression here, unless you have plenty
of server cpu power and or limited bandwidth
