Hyrax - Configuration

When you install Hyrax for the first time it is pre-configured to serve test data sets that come with each of the installed data handlers. This will allow you to test the server and make sure it is functioning correctly. After that you will want to configure it so that it works with your data.

Hyrax configuration is straight forward with one important caveat: Because the OLFS provides a particular view of the data and THREDDS can provide a slightly different view, it is very important that the configuration of the THREDDS catalogs and the BES are coordinated. In particular this means that each top level data set (be it a collection or an "atomic data set) that the BES exposes must have a separate <datasetScan> entry in the THREDDS catalog.

Confused? Hopefully you won't be after you've read the following documents.

Robots

To correctly deploy a robots.txt file for Hyrax, you must correctly deploy it for Tomcat. This means that your robots.txt file must be accessible here:

   http://you.host:port/robots.txt

For example:

   http://www.opendap.org/robots.txt

Placing it lower in the URL path doesn't seem to work.

In order to get Tomcat to serve the file from that location you must place it in $CATALINA_HOME/webapps/ROOT

If you still find that you system is being cruelly burdened with robot traffic then you migh want to try the BotBlocker handler for the OLFS.
