PID Information Types WG

Case Statement: 

In complex data domains, unique and persistent identifiers (PIDs) associated with specific information are the core of proper data management and access. They can be used to give every data object (including collection objects) an identity that enables referring to the data resources and metadata and, additionally, to prove integrity, authenticity and other attributes. But this requires a PID to be uniquely associated with specific types of information, and those types and their association with PIDs must be well managed. Therefore it is useful to specify a framework for information types, to start agreeing on some essential types, and to define a process by which other types can be integrated. The framework provides generic facilities only, which can and must be employed by specific communities to support their needs. The focus of the working group therefore is on cross-community concerns.

The Published Output can be cited this way:

Termination at RDA P4 Amsterdam

The PID Information Types WG was set to terminate after 18 months of activity at the Amsterdam 4th RDA Plenary. This was the last session of the WG with a look at the final deliverables and discussion of already emerging future activities within RDA.

After P4, the WG entered the official RDA outcomes process as one of the first groups to do so. The deliverables as listed above were bundled in a package and submitted.

I have some questions. Who shall I contact?

Simply contact one of the WG chairs, Timothy DiLauro or Tobias Weigel.

What about follow-up activities?

DKRZ is active in furthering the outcoms of PIT and the general concepts of information types and type registries within the EUDAT project and the ESGF infrastructure. Other initiatives such as the Deep Carbon Observatory and the Materials Genome Initiative innovation infrastructure as represented in the Materials Data IG have also indicated potential interest. Activities will also continue within RDA with possible follow-up WGs.

Data Fabric and PIT updates

Dear DF and PIT,
I understand that there have been some questions during one of the Data
Fabric session at P7 today on the status and future of the PIT
developments. Since PIT is considered to be part of the overall Data
Fabric approach, I would like to take this opportunity to give a few
essential updates here that shed some light on the more recent
activities since the end of the WG lifetime:
- The PIT API and demonstrator are available as an RDA recommendation
and I am quite happy to see that there are a couple of adoption projects

PID Info Types demonstrator

Dear all,
we have good news on our overall WG outcomes - they are in a mature
enough stage now - also thanks to Tom Zastrow from RZG - so that we
would like to get your valuable feedback. Some of you have already asked
for more details, and we hope the information given here comes at the
right time.
The client demonstrator GUI is accessible here, courteously hosted by
Tom/RZG - also note the walk-through on the right-hand side for simple
usage examples:
