What is EPOS?
EPOS is a long-term plan for the integration
of research infrastructures for solid Earth Science in Europe
EPOS integrates the
existing (and future)
advanced European facilities
into
a single, distributed,
sustainable infrastructure
taking full advantage of new
e-science opportunities

Metadata model
- 3-layers
- Manage the complexity
(see previous slide)
- CERIF (formal syntax,
declared semantics)
Functions
-Discovery, selection
-Impact assessment
-Manage interoperability
Issues (selection of)
- heterogeneity
- Many standards to be
mapped from TCS
- Ontologies
- Complex work
Discovery (DC, DCAT, ISO19139)
Contextual (CERIF metadata model)
Detailed (community specific)
Web portal, Spatio-Temporal Search
domain specific – data
(TCS or Naational Ris)

Is EPOS catalogue FAIR?

17.
FAIR - Findability
To be findable… EPOS
F1. (meta)data are assigned a globally unique and persistent
identifier
Depends on
communities
F2. data are described with rich metadata
F3. metadata clearly and explicitly include the identifier of the
data it describes
Depends on
communities
F4. (meta) data are registered or indexed in a searchable resource

18.
FAIR - Accessibility
To be acessible… EPOS
A1. (meta) data are retrievable by their identifier using a
standardized communications protocol
A1.1 the protocol is open, free, and universally implementable
A1.2 the protocol allows for an authentication and authorization
procedure, where necessary
WIP
A2. metadata are accessible, even when the data are no longer
available

19.
FAIR - Interoperable
To be interoperable… EPOS
I1. (meta)data use a formal, accessible, shared, and broadly
applicable language for knowledge representation.
Difference between
MD representation and
MD exposition
I2. (meta)data use vocabularies that follow FAIR principles
WIP
I3. (meta)data include qualified references to other
(meta)data

20.
FAIR - Reusable
To be reusable… EPOS
R1. meta(data) are richly described with a plurality of
accurate and relevant attributes.
R1.1. (meta)data are released with a clear and accessible
data usage license
R1.2. (meta)data are associated with detailed provenance
WIP
R1.3. (meta)data meet domain-relevant community
standards

Conclusion
1. EPOS catalogue (CERIF – based) is shaped to be
FAIR
2. Much depends from the communities
3. Importance of community building action
4. Promote FAIR culture (training initiatives)
