This is Search for metadata uploaded to DataCite's Metadata Store (MDS). It is based on Solr.
To learn more about DataCite please visit our website
To use this software please go to http://search.datacite.org
Using Docker.
docker run -p 8080:8080 datacite/search
You can now point your browser to http://localhost:8080 and use the application.
For a more detailed configuration, including serving the application from the host for live editing, look at docker-compose.yml in the root folder.
Search a java servlet web application. You need a servlet container such as Tomcat, Maven and JDK (OpenJDK from Ubuntu works fine). All dependencies are managed by Maven public repositories.
Solr requires a home directory to store the index and some properties. Be aware that the user running running your servlet container must have write access to this directory.
The content of solr_home has to be copied to your selected solr home directory.
All other required files will be in the war-file.
The git repository has a number of *.template files, listed below. Those files are templates for the various configuration files, passwords, IP addresses etc.
If you are using Docker, the configuration files are generated automatically from variables in the .env file. Modify the variables in .env.example and rename it to .env.
For manual configuration you need to make a copy omitting .template from file name, and adjust the values according to your local environment.
MDS database specific properties.
You will need to specify JDBC string, for example:
jdbc:mysql://localhost:3306/datacite?useUnicode=true&characterEncoding=UTF8
Specify the path to your preliminarily chosen solr home directory by replacing <dir>.
Your usual log4j stuff.
Public access should only be granted for the /public path.
The following indexes are required on the database:
create index dataset_version on metadata (dataset, metadata_version);
create index dataset_updated on media (dataset, updated);
Follow along via Github Issues.
After deploying the following resources are of interest:
/public/ui- search user interface/- admin interface
Data from MDS is imported via Solr's DataImportHandler. You can access it via the admin interface. Another option - especially useful for cron jobs - is scripts/solr-client. Simply try
export SOLR_URL=http://localhost:8080/search
scripts/solr-client import delta
for a delta import of MDS metadata. See solr-client help for usage.
You can monitor memory and CPU using JConsole and a remote connection on the following host:
localhost:17264
