This document summarizes a presentation by Dr. Johannes Keizer from the Food and Agriculture Organization of the UN on elements for an information infrastructure for linked open data. The presentation outlines core values of openness, meaningfulness, reliability, and actionability. It describes principles for a sustainable infrastructure that allows heterogeneous data featuring semantics and exposes everything as linked open data. Elements of the infrastructure include tools for vocabularies, triples, data services, and cloud storage. The goal is not one infrastructure but facilitating interoperability across multiple infrastructures.

agINFRA values
We truly believe that scientific data
A | Open | Must be open and interlinked
NOT subject to barriers, based on standard formats and avoiding building
data silos due to lack of interrelatedness and ad-hoc APIs.
B | Meaningful | Must be meaningful through explicit semantics
C | Reliable | Must be reliable, traceable and accessible
D | Actionable | Must be actionable trough services that empower research
Reusing the semantics already provided in mature terminologies and
ontologies that are exposed and interlinked through the Web.
Any kind of research objects can be stored in the data infrastructure, and
there are NO barriers to expressing relations between these objects to
capture the context of research activities.
Data is not useful without flexible and adaptable services that allow
researchers to act on the data in the ways they need.

agINFRA principles
Infrastructure
Be sustainable in the
long term
Allow for heterogeneous
and rich kinds of data
featuring semantics
Expose everything as
linked open data
We trust that the following principles support the values
People
Know and adapt to the
needs of researchers
Provide out-of-the-box,
easy to adopt components
Foster collaboration and
sharing of data, via search
but also casual discovery
Services
Use existing components
supported by strong
communities
Create open services that
can be easily composed
Adapt services to research
workflows

Infrastructure, but to
facilitate many
infrastructures,
or better to create elements
for interoperable
infrastructures
