Extrods is a collection of extensions for iRODS, Rule Oriented Data Systems. IRODS is the next generation of data management cyberinfrastructure.

Currently, extrods consists of the following projects:

Jargon

Java client API

Prods

PHP client API

iRODS browser

An Ajax based web client, design for end-users. iRODS browser installation requires Prods for its web services.

Cross Zone Data Replication Service

A light weight approach to replicate data from a designated iRODS zone to another.

Contributed Software

iRODS RPM

RPM packages of server (both ICAT and non-ICAT) packages and client commands. Support for Oracle and Postgres ICATs and GSI auth. The repository provides patches and extra source bundles along with the RPM package spec files and source RPMs for use on any supported system.

DEB

Initial packages of iRODS server and client for Ubuntu are now downloadable. These have been compiled using Ubuntu 8.04 to support a Postgres ICAT using the distribution versions of Postgres and unixODBC (though it seems that a version of unixODBC more recent than 2.2.11 is required to run correctly). If different compilation configurations are required then obtain the sources from Subversion and edit the debian/rules file as appropriate and then rebuild the package. Various combinations will be created and uploaded to this repository over the next few weeks.

Cross Zone Data Replication Service

The cross zone data replication service (CZDRS) is a light weight approach for data to be replicated from a designated iRODS zone to another. The CZDRS model is quite different from the data replication function within iRODS. The native iRODS replication function replicates the data only in file-level with a single metadata catalog to maintain the replica information while CZDRS replicates data for both file and metadata. The concept of the CZRS was initially proposed by the Chronopolis project (https://chronopolis.sdsc.edu/). -Bing Zhu
