Thought I'd post this here for reference
To expose an external WMS service (such as a 3rd party WMS or a standalone
installation of NcWMS) through TDS and also included in ISO metadata, one can
do this:
Define a service tag pointing at your external WMS server outside of the
typical compound services.
<service name="agg" base="" serviceType="compound">
<service name="odap" serviceType="OpenDAP" base="/thredds/dodsC/"/>
...
</service>
<service name="ncwms_in.usf.fvcom.ike.ultralite.vardrag.nowave.2d"
base="http://ec2-107-21-136-52.compute-1.amazonaws.com:8080/wms/in_usf_fvcom_ike_ultralite_vardrag_nowave_2d/";
serviceType="WMS" suffix="" />
Inside of your dataset tags: use the <access> tag:
<dataset name="FVCOM - IKE - Ultralite - Variable Drag - Waves - 2D"
ID="in.usf.fvcom.ike.ultralite.vardrag.wave.2d"
urlPath="auto/in.usf.fvcom.ike.ultralite.vardrag.wave.2d">
<access serviceName="ncwms_in.usf.fvcom.ike.ultralite.vardrag.wave.2d"
urlPath=""/>
<access serviceName="agg"
urlPath="auto/in.usf.fvcom.ike.ultralite.vardrag.wave.2d"/>
...
</dataset>
The result is this:
