Metacat Administrator’s Guide

Metacat is a repository for data and metadata (documentation about data) that helps scientists find, understand and effectively use data sets they manage or that have been created by others. Thousands of data sets are currently documented in a standardized way and stored in Metacat systems, providing the scientific community with a broad range of science data that–because the data are well and consistently described–can be easily searched, compared, merged, or used in other ways.


Your Metacat instance MUST be either 2.19.0 or 2.19.1 before you can upgrade it to 3.0.0.

An external Solr HTTP server is required as of Metacat version 2.13.0. You should add the tomcat user to the solr group and the solr user to the tomcat group in order to avoid the file permission issues. The details can be found on the Solr Server part of the installation page.

If this is the first time you have installed an external Solr server, you need to re-index all existing objects in the Metacat instance. The instruction can be found on the Regenerating The Index part of the Metacat indexing page.
