Name: RCommands

Description:

STFC has assembled the RCommands clients and server with support from the Natural Environment Research Council, as part of the e-Minerals e-Science Project. RCommands is designed for metadata management.

The RCommands is a framework for managing metadata that has a number of powerful tools for tasks such as creating, listing and searching on metadata. The tools are used in conjunction with RMCS to automatically harvest metadata at the end of simulations performed within a grid computing environment. If output property values are also collected as metadata, the RCommands framework can be used to collate core results from an extensive grid-based combinatorial study, thus using metadata as a primary interface to data and making analysis of grid simulation studies particularly easy whilst retaining accuracy. The RCommands framework provides client tools in the form of shell commands and web interfaces.

The RCommands comprises:

An infrastructure including a central database, a set of unix shell commands and a web interface, for creating, managing and manipulating metdata associated with files and collections of files stored within the distributed resources of a data grid. The package includes tools for searching for files based on their metadata.

Source code and packages for RHEL, Debian and Oscar for the RCommands are in the e-Minerals SRB: /home/rty.eminerals/RCommands/0.2.2.

In addition to the man pages, there is a tutorial that Martin Dove put together for a recent NIEeS event at: http://www.niees.ac.uk/events/srb2006/srb_demo_2.html.

The Metadata editor can be accessed via: https://forth.dl.ac.uk:8443/metadatamanager/login.html
