The gLite documentation page:
http://glite.web.cern.ch/glite/documentation/R3.0/default.asp
Look at these:
Workload Management System User and Reference Guide
WMProxy User Guide
JDL Attributes Specification (submission via WMS Network Server)
JDL Attributes Specification (submission via WMS WMProxy)
Logging and Bookkeeping User and Reference Guide
The WMS currently supports DAGs, but a lot of problems were found
with the robustness of the implementation. Since the LHC experiments
were only interested in job _collections_ so far (bulk submission),
the emphasis has been on getting that to work reliably instead.
In the upcoming gLite 3.1 WMS (in certification now) collections are
no longer handled by the generic Condor DAGman code.
A collection or DAG is just a bunch of jobs, each of which can be
separately matched to an LCG-CE or gLite CE.
The LCG-RB does not support any of that.
