Quite some time ago Unico created a Locationmap module for Forrest. This
allows us to specify where the source file for a request is located
independently of the client request URL. this excellent code has sat in
our SVN for far too long, waiting for someone with a strong enough itch
to make real use of it. With the release of 0.7 and therefore the start
of 0.8 development it has come out of hiding and is now enabled in our
core. It is a key part of integrating repositories and CMSs such as
Slide, Daisy and Lenya.
The Locationmap code [1] reuses code from Cocoon rather than starting
from scratch. We now need to enhance the code to allow the mounting of
sub-locationmaps in the same way that Cocoon can mount sub-sitemaps. We
are hoping that this can be done through a simple reuse of Cocoon code.
Unfortunately, nobody in Forrest knows the insides of Cocoon well enough
at this time so it would seem now is time for some of us to learn...
A locationmap consists of a number of matchers, for example:
<match pattern="remoteDemo/**.xml">
<location
src="http://svn.apache.org/repos/asf/forrest/trunk/site-author/content/xdocs/{1}.xml";
/>
</match>
For a complete locationmap file see
http://svn.apache.org/viewcvs.cgi/*checkout*/forrest/trunk/site-author/content/xdocs/docs_0_80/locationmap.xml?rev=210059
The map is built by the build(...) method in
org.apache.forrest.locationmap.lm.LocationMap (see
http://svn.apache.org/viewcvs.cgi/forrest/trunk/main/java/org/apache/forrest/locationmap/lm/LocationMap.java?view=markup
)
As can be seen in this code Unico reused much of the sitemap code from
Cocoon. My question is, can we also leverage the <map:mount...> code?
Any pointers as to how to do this would be greatly appreciated.
