Here is found details of the locations and purposes of the Fedora 4 configuration files. For details on how to enable and configure these options, see this page. |
Fedora RESTful HTTP API uses the open source Jersey RESTful Web Services framework that provides support for JAX-RS APIs and serves as a JAX-RS (JSR 311 & JSR 339) Reference Implementation. The jersey servlet dispatcher is configured in web.xml as follows:
<servlet> <servlet-name>jersey-servlet</servlet-name> <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>org.fcrepo</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> |
The following spring files exist in a directory as configured in web.xml, which contains a context-param element with param-name "contextConfigLocation". The param-value points to your spring context configuration files, WEB-INF/classes/*.xml. Note that these files are in the source tree under fcrepo-webapp/src/main/resources/spring and copied to WEB-INF/classes upon build.
<bean name "modeshapeRepofactory" class= "org.fcrepo.kernel.spring.ModeshapeRepositoryFactoryBean">
<property name="repositoryConfiguration" value="${fcrepo.modeshape.configuration:classpath:/config/single/repository.json}"/>
</bean> |
Fedora 4 uses Modeshape, a JCR implementation. We distribute a handful of known-good configurations for Modeshape and Infinispan, although we anticipate configuration tuning for deployment environments will be common.

These configuration files are copied to WEB-INF/classes from fcrepo-configs/src/main/resources upon build.

fcrepo.modeshape.query.enabled:true fcrepo.modeshape.query.mode:sync |
Fedora 4 uses the Modeshape query index to power administrative search APIs. It can be disabled (or switched to asynchronous mode) to improve performance (see below).
fcrepo.modeshape.index.location:target/indexes fcrepo.infinispan.cache_configuration:config/infinispan/leveldb-default/infinispan.xml |
Fedora 4 can be configured to use different Infinispan configurations. By default, Fedora 4 configurations use the leveldb-default configuration.
fcrepo.ispn.repo.CacheDirPath:target/FedoraRepository/storage |
Fedora 4 will store object properties to fcrepo.ispn.repo.CacheDirPath. These probably won't be very large, and should be stored on fast disk. The object properties are stored as binary JSON documents within the given cache store configuration.
fcrepo.binary-store-path:target/binaries fcrepo.ispn.binary.CacheDirPath:target/FedoraRepositoryBinaryData/storage |
fcrepo.ispn.binary.CacheDirPath:target/FedoraRepositoryBinaryData/storage - path to store binary content (when it's stored in infinispan e.g. /config/infinispan/clustered/infinispan.xml)
Fedora 4 stores binary content separately (to one of the above paths, depending on configuration). These files are stored hashed by the content SHA-1 hash.
If your application does not use the query index (which powers basic administrative search, and the simple fcr:sparql endpoint), you can significantly improve repository performance by disabling indexing, or using asynchronous indexing instead.

Different Infinispan configurations can also have an impact on repository performance.

namespace properties to enable XACML authorization
This is an indexer that listens to the Fedora JMS topic, retrieves a message including pid and eventType, looks up object properties, gets and passes the transformed or untransformed properties on to any number of registered handlers.
