currently I don't think anyone has built any perl modules to wrapper oslc.

one could certainly do it.   the Eclipse Lyo project http://www.eclipse.org/lyo/ intends to support other languages.

this article  does a good job of describing the data flows, authorization and services catalog discovery

here is a little windows batch file that will pull back the project list from a server.. it does not use the proper discovery methodology defined

<code>
set COOKIES=.\cookies.txt

set USER=xxxxx
set PASSWORD=yyyyy
set HOST=https://server:port


curl -k -c %cookies% "%host%/jts/authenticated/identity" >nul

curl -k -L -b %COOKIES% -c %COOKIES% -d j_username=%USER% -d j_password=%PASSWORD% "%host%/jts/authenticated/j_security_check" >nul

curl -k -L -b %COOKIES% "%host%/ccm/oslc/workitems/catalog
</code>

I posted another example to read/write SystemMessages with perl over REST. This shows you how to connect and login.
