PID Collections - P6 BOF session

23 September 2015- BREAKOUT 3 - 15:30

Several communities have expressed interest in leveraging aggregations of digital objects with particular focus on building such aggregations through PIDs and possibly providing identifiers for aggregation objects. There is however no unified cross-community approach to building and managing such collections and no common model for understanding them. The PID Information Types WG has defined a core model and the central interface for accessing object state information and provided a small number of example types, which were consequently registered in the Type Registry WG prototype. With these tools available to describe essential object information, collections can be described so to be able to deal with more than a single object at once.

The goal of this session is to coordinate and discuss plans for an RDA Working Group on PID Collections. Depending on the status of the group at P6, this session will serve as a kick-off or a pre-WG BoF. The proposed WG aims to provide a unified model of collections, specify an API for the most common operations and demonstrate the applicability along a multitude of RDA community use cases.


  1. Introduction and overview on the current case statement (20 min.). We will present the main points of the case statements, including the general approach of the proposed WG, its deliverables and the context within RDA and elsewhere, particularly regarding prior RDA WG efforts (slides attached)
  2. Use case presentations and discussion (45 min.). The initial use cases listed in the case statement are:
    • DKRZ
    • Perseus DL
    • BCO-DMO
    • SEAD project
    • Coptic SCRIPTORIUM
    • Ocean Data Interoperability Platform
    • Harvards Astronomy Abstract Service
    • Open Philology Project, University of Leipzig
  3. Discussion on possible adoption pathways and other relevant efforts (25 min.)

The case statement can be found here.

Attached to this page is also a short document giving a first practical view on collection usage.
