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

Is EPOS catalogue FAIR?

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

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 necessaryWIP

A2. metadata are accessible, even when the data are no longer

available??

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

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)
