THREDDS is a web server that provides metadata and data access for geospatial datasets.Purpose of this page is to explain how to configure a GeoNetwork service instance in order to fulfill the needs of gCube environment. Please refer to third party's website for further details.

Installation
Environment prerequisites :
- JRE 7+
- Tomcat 7+
Suggested environment : SmartGears installation.
Tomcat configuration
In D4Science infrastructure, the following configuration is recommended :
- Setting the catalog directory :
- Symbolic link
- $TOMCAT_HOME/content -> /data/content
- Set JRE property :
- THREDDS_CONTENT_ROOT=$TOMCAT_HOME/content
- JAVA_OPTS="-Dtds.content.root.path=$THREDDS_CONTENT_ROOT $JAVA_OPTS"
- Symbolic link
Thredds Catalog configuration
Once Thredds is deployed and the containing tomcat instance is started, the webapp creates a basic configuration under $THREDDS_CONTENT_ROOT/thredds. The following files in such directory need to be replaced with the ones in shared workspace folder https://goo.gl/ct28Jn :
- catalog.xml
- threddsConfig.xml
Configuring as SmartGears Application
In order to enable SmartGears to correctly handle the web application, the following values must be declared in its gcube-app.xml file :
- Name : Thredds
- Group : SDI
- Description : Unicar OGC compliant data catalog
The following SmartGears handlers should be excluded :
- request-validation
The following parameter needs to be set in order to configure integration with Data Transfer service (see THREDDS_CONTENT_ROOT setting above) :
- persistence location = THREDDS_CONTENT_ROOT
Legacy applications compatibility
In order to enable legacy application to publish data into THREDDS catalogs, the same machine should host a gCore installation with legacy service org.gcube.data-transfer.agent-service. This service needs write privileges on thredds catalog directory and its subdirectories, which legacy applications expect to be under "/data/content".
