TRiRODS is local meetup for users of iRODS software in the RDU area. TRiRODS works to build a strong sense of community, to offer a space for collaboration and sharing of individual implementations of iRODS, and to further the work on a hardened version of the code.

Quarterly meetups are planned for 2017. If you are interested in sharing your work at any of the sessions listed below, please email info@irods.org.

MetaLnx, Metadata for the Masses

By Stephen Worth, DELLEMC

Groups maintaining data repositories at the petabyte-scale are discovering that cataloguing associated metadata is necessary to properly access, recall and analyze data. To be successful they depend on researchers and data curators to design and provide the user defined metadata to be successful. Metalnx was developed to aid researchers with metadata management under iRODS (the Integrated Rule Oriented Data System) and is now an open source project (metalnx.github.io or www.github.com/metalnx)

This talk explains the motivation for this work, demonstrates the operational behavior of Metalnx, provides a preview of our work in data validation, and looks at a model for applying adaptive, hierarchical metadata to research curation.

About the presenter

Steve Worth coordinates innovation initiatives across Dell EMC global engineering centers, is a technical liaison between product groups and the global engineering network, and works in big data / digital asset management leveraging user defined metadata. Steve is based out of Dell EMC’s RTP Software Development Center which focuses on data protection, core storage products, and cloud storage virtualization.

Metadata Templates in iRODS

By Rick Skarbez, iRODS Consortium

Metadata templates represent a significant addition of functionality to iRODS’s handling of metadata. In base iRODS, metadata is stored in the catalog as unadorned attribute-value-unit (AVU) triples of strings. This is flexible for many use cases, but does not afford the grid administrators much control of any stored metadata. By extending iRODS metadata, specifically by associating the AVU triples stored in the catalog with metadata templates which can provide additional information about these metadata elements (or meta-metadata), we can now support a variety of interesting functions.

This talk will explain the motivation behind metadata templates, present a proof of concept implementation of metadata templates, and demonstrate the use of this implementation via their REST API, currently in development.

About the presenter

Rick Skarbez has a PhD in computer science from the University of North Carolina at Chapel Hill, and is a Systems Programmer for the iRODS Consortium. Rick has been working with iRODS since 2015.

A Developer’s Perspective on Extending iRODS to the Mid-Tier

By Mike Conway, RENCI

Mike will talk about employing iRODS in the mid-tier, lessons learned, and design concepts for the next version of Jargon. In addition, Mike will touch on how REST is structured, Discovery Environment, Web interface plans, and how iRODS can be extended.

About the presenter

Mike Conway is a Senior Data Science Researcher at RENCI. Conway was part of the Data Intensive Cyber Environments team that invented iRODS and conceptualized policy-based data management, and he is a developer with the iRODS Consortium. He was a lead developer on the NSF DataNet Federation Consortium formed to develop universal solutions to research data management.

Developing a Python Client Library for iRODS

By Antoine de Torcy, iRODS

Antoine will talk about what is in version 0.6.0 of the Python iRODS Client (PRC) and what to expect in the next release. We will look at an application of PRC to parallelize file transfer into iRODS.

About the presenter

Antoine is a C++ developer and has been part of the original iRODS development team since 2003. He joined UNC in 2008 and RENCI in 2013. Prior to that he was part of the Data Intensive Computing Environments group (DICE) at the University of California, San Diego. At DICE, Antoine wrote client and server components for iRODS and its precursor the Storage Resource Broker, and he worked on NSF-funded research projects that used iRODS for large scale management of scientific data. Antoine holds an engineering degree in Applied Mathematics and Computer Science from the University of Paris.

A Pilot of iRODS for Managing Next Generation Sequencing Data

By Todd Moughamer, Syngenta

DNA sequencing technology has evolved rapidly and resulted in data storage challenges for research organizations. Syngenta’s Next Generation Sequencing platform has been successful at getting data to researchers and analysts. However, there are opportunities to improve the users’ access to the data and the organization’s ability to manage and track data. Towards leveraging these opportunities, Syngenta has implemented a pilot of iRODS that integrates with their current processes and ways of working.

About the presenter

Todd Moughamer is a Senior Computational Biologist and leads the Next Generation Sequence Data Management at Syngenta.
