PID Kernel Information WG


Group details

WGs Wrapping up (from ~12 months after RDA endorsement)

As has been discussed in several awareness raising sessions with the RDA community at RDA Plenaries 7 and 8 in special sessions carried out in the Data Fabric IG and at two extracurricular RDA events, there is a gap to realization of the power of the combined RDA Recommendations (PID Information Types Recommendation and Data Type Registry Recommendation). This gap, described in more detail below, is in coming to consensus around what makes up PID Kernel Information. By convening interested parties in the RDA community to define PID Kernel Information, and having a PID Kernel Information Recommendation a complementary recommendation in the RDA recommendation suite will allow adopters of the core RDA recommendations (PIT Data Types and Data Type Registry) to take full advantage of the unique power that these recommendations have when combined.

This WG aims to converge through a series of discussions and a narrowing process on the smallest number possible of versions (or profiles) of PID Kernel Information (1 is ideal but not likely).  These versions/profiles will be the primary output of the WG. 

The group has most recently started to assemble a coherent set of guiding principles that further define the purpose and key requirements underlying the whole concept of PID Kernel Information. Any profiles must adhere to these principles. They also shape the possible infrastructure that can support Kernel Information and facilitate user interaction, filtering, decision-making and other actions.


The group's output is an RDA Recommendation, which is available here:

Follow-up WG on Data Type Registries

Dear colleagues,
governance and interoperability between DTRs  is a still open issue in a
digital object ecosystem and in the DTR session at RDA P13 there was an
agreement that these topics should be the main concern of a third round
of the DTR WG in RDA.
Larry Lannom and myself have drafted therefore a case statement, which
we would like to submit to RDA to establish a follow-up WG.
We would like to encourage you to comment on the case statement and join
as supporter.

Fwd: Mark A. Parsons - new related research

We talk mostly about Handles, but our Kernel should work for ARKs just as well. As such this is an interesting article about the growth of ARKs in the French library community and concomitant governance issues that may inform some of our discussion.

Follow-up WG on PID Kernel Information Profiles

Dear colleagues,
the discussions at the PID Kernel Information session at the RDA P13
indicated that there is more work to be done to further define PID
Kernel Information profiles, mechanisms to manage and govern them, and
further build the technical connections to related essential components,
notably a profile registry that can be built potentially on top of the
Data Type Registry.
Therefore, we (myself, Beth Plale and Jens Klump) have drafted a new
case statement, which we would like to submit to RDA to establish a

Re: [pid-kernel-info-wg] Updates to the PID KI recommendation draft: Digital Object...

I made a single comment on the Dublin Core / PID Kernel connection.
Otherwise, nothing to contribute. Its a substantive and well thought out document and I think will form the basis for future discussion, trials, and probable revision once we get enough real world experience.

RE: [pid-kernel-info-wg] Updates to the PID KI recommendation draft: Digital Object...

Hello Tobias; all,
I have provided some comments to the draft.
It would be easier to use the specification if there were examples of metadata to be provided for each data element. The specification should also clarify if the elements are repeatable. And Mandatory column should have three options: Yes, Yes (if applicable) and No. In some cases additional information could be useful; for instance, Version number should be mandatory if it is not 1.
