iRODS Development Update: July 2015

In this post we review the July development activities of the iRODS Consortium, which focused heavily on the 4.1.4 release.  The Technology Working Group was cancelled and A Call For Participation was sent to the TWG, Advisory Board and iRODS Chat list for working groups focused on mime types, persistent identifiers, and the upcoming enterprise message bus.

Focus on 4.1.4

For the month of July, most of the development team worked on issues related to the 4.1.4 release.  We worked with a developer from our collaborators at iPlanton a new implementation of the fuse client, which promises more stability.  During this time we continued to fix other bugs as they arrived.  We closed 33 issues for 4.1.4, out of the 38 created overall.

External Plugins

We are currently working on new releases of external storage plugins for HPSS and WOS.  The work on WOS has included the packaging of the wosrest daemon in order to optimize the communications between iRODS and the daemon.  The daemon will need to be launched as a separate service and the plugin configured to communicate directly with the local service.  HPSS has also been enhanced to include the ability to support unicode characters in the physical path.

iRODS 4.2

Progress continues for iRODS 4.2 as we first focus on infrastructure and bug fixes before we begin work on integrating the new rule engine plugin interface. Highlights from the infrastructure work include refactoring the entire setup and upgrade code, removing the mix of perl and bash, into a new python library. We are also investigating the standardization on a C++14 compliant compiler across all platforms for the support of the new rule engine plugin.

Working Group Call for Participation

The iRODS Consortium Technology Working Group has identified several important topics that have broad impact, both on grant-funded projects in the academic arena, as well as on new and existing users from the community. These working groups would work to gather use cases, examine existing implementations, and synthesize standards and best practices around which the iRODS Consortium may provide packaged reference implementations.

  1. Mime Types
  2. Persistent Identifiers
  3. Enterprise Message Bus (EMB)
  4. Services related to the EMB such as:
    1. Auditing Framework
    2. Notifications

Once participants have been identified, we expect each working group to meet for hour-long web conferences about every two weeks for a span of approximately 3 months. We will begin by hosting presentations from our collaborators to examine existing production implementations.  Ultimately, our desired outcomes are documentation and decisions on: message formats, schemas, serialization technology, topics and associated services, expected control flow from clients through iRODS to and from these services, and potential new API calls from iRODS to support new functionality.

If you are interested in playing a role in these discussions, please email referencing any or all working groups you would like to join.
