Dear Mr. Caron,

I work for NOAA NESDIS CLASS Project.  We are planning to deploy THREDDS
Data Server initially at NCDC CLASS.
I was reading the PowerPoint document posted at
http://www.unidata.ucar.edu/projects/THREDDS/tech/tds3.17/reference/index.html

I have a few questions that you can answer right away..

In Slide 2 ("TDS is a data server), I see "catalog.xml" sent to remote user
and "configCatalog.xml" read by THREDDS Server. Is the "catalog.xml" file
one of THREDDS Dataset Inventory Catalogs? Would you please let me know
what "configCatalog.xml" is for? Could it have since been renamed
"threddsConfig.xml"?

no, thats a different file. configCatalog.xml just means "server side configuration catalog files".


BTW, you should be looking at the 4.0 docs:

http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.0/reference/index.html
http://www.unidata.ucar.edu/projects/THREDDS/tech/tutorial/index.html


What entities shown in Slide 2 are parts of the TDS? Could they be all
shown in the white rectangle (i.e., HTTP Tomcat Server and the elements
inside this box, configCatalog.xml, and Datasets)? Or could they be just
"THREDDS Server plus catalog.xml and associated web services (i.e., HTTP
Server, OPeNDAP, WCS/WMS, NetcdfSubset, and RadarServer)?

on that slide, everything except for RemoteAccess aand IDD Data is part of the TDS.
I would like to ask your permission to copy and modify the figure (Slide 2)
and to use it in one of my documents.

yes, you are welcome to use anything on our site.

Thank you very much.
