TDS Catalog Generation ServiceThe TDS Catalog Generation service has been DEPRECATED. Instead, please use datasetScan elements in TDS catalog configuration files.
The TDS Catalog Generation service must be enabled in the threddsConfig.xml configuration file before it can be used. This is done by adding the following:
<CatalogGen>
<allow>true</allow>
</CatalogGen>
The Catalog Generation service provides a web interface for controlling your catalog generation tasks. To use the catalog generation admin pages, TDS remote management must be setup and requires login with the "tdsConfig" role. The catalog generation admin pages are located at:
http://server:port/thredds/cataloggen/admin/
You will see something like:
Each row in the web form table is a single catalog generation task.
The form allows users to look at the configuration files and control
the frequency at which each catalog is generated. When a task's period
is set to zero, as in the two sample tasks shown above, the task is not
scheduled to run. The initial delay value allows the tasks to be
delayed rather than starting immediately upon scheduling; this can be
used so that all the tasks do not start running upon startup of the
servlet.
Before a new catalog generation task can be added a Catalog Generator configuration file is required.
A CatalogGen configuration document is an XML document that
describes how to produce a THREDDS catalog by scanning or crawling one
or more dataset collections. Each CatalogGen configuration document is a skeleton THREDDS catalog containing one or more metadata elements of type "CatalogGenConfig". Each "CatalogGenConfig" metadata element will be replaced by dataset elements representing the datasets that make up the collection described by that metadata element.
You will need to write a CatalogGen configuration document that describes how to access the datasets you want to catalog, how to group those datasets, and how to name those datasets. The syntax and meaning of the CatalogGen config files are described on the "CatalogGen Configuration" page.
