Stefano Nativi presents the RDA.
Workshop title: Organising high-quality research data management services
Workshop abstract:
Open science needs high quality data management where researchers can create, use and share data according to well defined standards and practices. this is one of the pillars of Open Science. In the data management landscape we find quite a few organisations that aim at achieving this, however to get it right, a collaboration is called for where all can play a suitable role and present this in a consistent way to the researcher.
The proposed workshop brings together representatives of standard organisation (RDA), eInfrastructures (EUDAT) and Libraries (LIBER) that together can organise the high quality data management for research.

2. Genesis
launched in 2013 by the European
Commission, the US NSF and NIST,
and the Australian Government’s
Department of Innovation
Vision
Researchers and innovators openly
share data across technologies,
disciplines, and countries to address
the grand challenges of society
Mission
RDA builds the social and technical
bridges that enable open sharing of
data.

Cycle can be manually controlled or semi-automatically via pre-set pipelines.
Even in case of semi-automatic pipelines humans are close-in "designers“
(diagram is well-known in DFIG)

Abstractions Vs Implementations
Distinguish between two different types of Workflow
specifications/notations
Abstract Workflow
Executable Workflow
Abstract Workflow (Business Process) specification
Generated by Process Experts
Based on abstract and well known object types
Implementation/Technology independent
Executable Workflow
Generated by IT experts –e.g. Web Services experts
Based on accessible object implementations –e.g. Web Services
Technology dependent –e.g. workflow engines and related
languages
10. 10
Abstractions Vs Implementations
PID and Object typing help fill the gap
Brokering services (e.g. Data services brokering,
Processing services brokering) help fill the gap.

Intermediation functionalities have been done for many
years by the diverse Communities to support their
applications –see end-to-end architecture
With the advent of the Data Web, it‘s time to make it in an
automatic way –see T-TAP
Pros
More effective (i.e. multi-disciplinary),
More sustainable and scalable,
More re-usable
Cons
Need for a (new) governance and trust
Need for a more typified approach
Thinking Outside the Box
12. 12
In RDA the Data Fabric initiative is enabling Type-Triggering
automation to enable a more structured Data Market
Need to move from the current infrastructure abstraction
level to a Global Digital Object Cloud
Abstraction versus implementation complexities can be
addressed also by using brokering and intermediation
services
In the Data Web era data brokering services should be
externalized (brokering-as-a-Service)
RDA has addressed business models for such services
Data Fabric, Type-Triggering automation, and Brokering
services can play an important role to enable the
collaboration among RDA, EUDAT and LIBER.
