Using the Opendap Data Connector In Kepler
Instructions
- You will need a recent version of Kepler. If you don't have access to Kepler CVS, download the nightly build:
- http://kepler-project.org/nightly/zip/
- (get kepler20080129.zip or newer)
- Download kepler-odc-1.zip:
- This contains several files. For each move into the following directory: ($KEPLER = top level Kepler directory.)
- datasets.xml : move into $KEPLER
- gazetteer.txt : move into $KEPLER
- opendap-Not.A.Release.jar : move into $KEPLER/lib/jar/opendap (replace existing opendap-Not.A.Release.jar)
- odc.jar : move into $KEPLER/lib/jar/opendap
- ods-actor.kar : modified Opendap actor, can be anywhere.
- ods-wf.xml : workflow using modified Opendap actor, can be anywhere.
- Start Kepler
- Import modified Opendap actor into Kepler:
File menu -> Import Archive (KAR) -> ods-actor.kar
- Load workflow:
File menu -> Open File -> ods-wf.xml
- Double-click on OpendapDataSource2 actor to configure parameters.
- Click on the runODC check-box; ODC should start. BEFORE using ODC, do
step 8.
- Close the actor's configure parameters box by clicking Commit or Cancel.
(ODC GUI will NOT respond until this is done).
- Select a dataset in the ODC. This can be done by clicking on one of
the folders and double-clicking on one of its files. This should take
you to the Retrieve pane/tab. In the middle-pane, double-click on a
dataset and the fields should appear in the "Additional Criteria" pane
on the right. Select some of the fields by clicking in the check boxes.

# Change pull-down next to "Output to" button
** (bottom right) to Kepler, and click "Output to" button.
# Close ODC, then Opendap actor will reconfigure output ports to match
constraints set in ODC.
# (Optional) Connect output port(s) to Display actor and run workflow.
** NOTE: depending on the size of the dataset you selected, running the
workflow could take a long time.
