hi *!
i thought i'd better revive this old thread instead of starting a new one:

i just played around with the generator. since i want to access the
metadata from my page2shtml.xsl, i added the following to my publication
sitemap:
<map:match pattern="lenyabody-*/*/*/*/**">
<map:aggregate element="cmsbody">
<map:part src="cocoon://modules/sitetree/{2}/{3}/breadcrumb/{5}.xml"/>
<map:part src="cocoon://modules/sitetree/{2}/{3}/tabs/{5}.xml"/>
<map:part src="cocoon://modules/sitetree/{2}/{3}/menu/{5}.xml"/>
<map:part src="cocoon://modules/sitetree/{2}/{3}/search/{5}.xml"/>
<map:part
src="cocoon:/{2}/{3}/meta?docid={page-envelope:document-id}"/>
<map:part src="{resource-type:format-xhtml}"/>
...
i came across two issues i don't understand:
(1) why are namespaces stripped by default? i had to comment out
<map:transform src="fallback://lenya/xslt/util/strip_namespaces.xsl"/>
later in the pipeline to get the lenya: prefix back.
(2) what is the format of <lenya:workflowVersion/> ? is there any way to
get the information in sane xml? the information i want to extract is
"page last updated on <date> by <user>". would be simple by accessing
the metadata files directly, but i'm listening to andreas' advice and
try not to bypass the lenya api...

jörn

done
After adopting above commit for your pub, change:
<map:part
src="cocoon:/{2}/{3}/meta?docid={page-envelope:document-id}&lang={page-envelope:document-language}"/>
Thanks for the feedback. :)

Well if you used the example of the default pub then we have set
lang="en"
http://svn.apache.org/viewcvs.cgi/lenya/trunk/src/webapp/lenya/pubs/default/sitemap.xmap?rev=365905&view=markup
...
<map:match pattern="**meta">
<map:generate type="lenyaMetaData">
<map:parameter name="docid" value="{request-param:docid}"/>
<map:parameter name="lang" value="en"/>
</map:generate>
<map:serialize type="xml"/>
</map:match>
...
I will change it right now to
<map:parameter name="lang" value="{page-envelope:document-language}"/>

Yeah, that is the default behavior, if you do not specify which language
you want:
org.apache.lenya.cms.cocoon.generation.LenyaMetaDataGenerator
....
if (this.language == null) {
this.language = pub.getDefaultLanguage();
}
...

See <map:handle-errors>
http://cocoon.apache.org/2.1/userdocs/concepts/errorhandling.html
There are examples in publication-sitemap.xmap in the default pub.
You can only have one <map:handle-errors> per <map:pipeline>, so you
probably want to wrap your <map:match>:
<map:pipeline>
<map:match></map:match>
<map:match></map:match> (Optional additional matches using the same
error handling.)
<map:handle-errors>
</map:handle-errors>
</map:pipeline>
<map:pipeline>
... Another pipeline with different error handling.

(i'm not sure why it looks for the english version here, since my
default locale is DE and i have not created a "language version" yet.)
i still want to include the metadata in my pipeline. is there some xmap
setting that will make the pipeline continue if a generator fails?
