Findable

Accessible

Reusable

https://doi.org/10.1038/sdata.2016.18

F1. (meta)data are assigned a globally unique and persistent identifier

 

F2. data are described with rich metadata (defined by R1 below)

 

F3. metadata clearly and explicitly include the identifier of the data it describes

 

F4. (meta)data are registered or indexed in a searchable resource

 

To be Findable:

https://doi.org/10.1038/sdata.2016.18

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

 

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

To be Accessible:

https://doi.org/10.1038/sdata.2016.18

I1. (meta)data use a formal, accessible, shared, and
    broadly applicable language for knowledge representation.

 

I2. (meta)data use vocabularies that follow FAIR principles

 

I3. (meta)data include qualified references to other (meta)data

To be Interoperable:

https://doi.org/10.1038/sdata.2016.18

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

 

  R1.3. (meta)data meet domain-relevant community standards

To be Reusable:

Assembling a dataset

A Research Object bundles and relates digital resources of a scientific experiment or investigation:​

 

Data used and results produced in experimental study​

Methods employed to produce and analyse that data​

Provenance and settings for the experiments​

People involved in the investigation​

Annotations about these resources, to improve understanding and interpretation
