Brief introduction describing the activities and scope of the group(s)

From Observational Data to Information IG: OD2I IG explores data, information, and knowledge in research infrastructures. Key issues are the distinction between data and information, in particular observations and derivative information; the processes that evolve observational data into information, i.e. how data evolve to (are “cooked” to become) information along value chains involving data interpretation processes; as well as processes for acquiring and curating the derivative information back into research infrastructures as new assets that can be further exploited (published, processed, used, etc.).

Brokering Framework WG: The scope of the WG covers data sources from research and scholarly communication. Within this domain obstacles for wider application of brokering techniques are:

• Multiple service protocols for data discovery, access, and application or processing;
• Multiple content standards for data and metadata, augmented by Community profiles and non-standard implementations;
• Multiple vocabularies and ontologies.
• Multiple adaptation and mediation modules that are not guaranteed to be compatible.

Research projects and research data infrastructure initiatives often solve problems associated with wide diversity as a matter of course, but the knowledge gained and components developed during such a process are not visible and useful to others. Furthermore, project life cycle limitations lead to lack of sustainability, loss of expertise, code, and infrastructure.

Meeting objectives

In this session we will discuss how increasing automation of the value chain, leading from observation data to information and knowledge products, and to what extent these automated processes
1. Can be described generically within the conceptual framework for brokering and mediation;
2. Are repeatable and applicable for multiple sources meeting common service interface specifications;
3. Are implemented in the real world, and can be included into a set of test cases for the brokering and mediation registry;
4. Requires brokering using registered service endpoints, ensuring that value chain workflows are executed reliably and repeatably.

Brokering Framework Working Group:

Please specify who is your target audience and how they should prepare for the meeting

All members of the RDA may find this session interesting, in particular those with an interest in the value chains linking scientific evidence to societal benefit. The work presented in this sessions can also be useful to many other domains. In particular, we feel the following IGs and WG may find this session interesting:

Participants should prepare for the meeting by considering the following:

• How does one describe a mediation service conceptually? What are the properties and characteristics of such a concept?
• How does one describe a brokering service, and how does it relate to mediation components and services?
• What type of operational service can be used to register mediation and/or brokering components? Can components and services be described using existing infrastructures, such as DataCite, Scholix, or similar?
• Do you know of use cases involving brokering and mediation?

There is a context-setting discussion paper that can be accessed here:

In this document, which describes the mediation and brokering requirement within SAEON, we make the argument that generically, mediation attempts to adjust one or more of the following interoperability requirements: syntactic (protocols and format of service calls), schematic (structure of the payloads served by components) and semantic (meaning of the content payloads).
