FAIR Data Point (FDP)

Python implementation of FAIR Data Point.

FDP is a RESTful web service that enables data owners to describe and to expose their datasets (metadata) as well as data users to discover more information about available datasets according to the FAIR Data Guiding Principles. In particular, FDP addresses the findability or discoverability of data by providing machine-readable descriptions (metadata) at four hierarchical levels:

FDP->catalogs->datasets->distributions

FDP software specification can be found here

FDP has been implemented in:

• Python
• Java

Installation

To install FDP, do

From pypi

pip install fairdatapoint

Deploy with Docker

Check fairdatapoint-service.

Deploy without Docker

Before deploying FDP, it's necessary to first have a running SPARQL database which can be used to store metadata.

pip install fairdatapoint

# fdp-run <host> <port> --db=<sparql-endpoint>
# Let's assume your <host> is 'example.com' and <sparql-endpoint> is 'http://example.com/sparql', then
fdp-run example.com 80 --db='http://example.com/sparql'

Web API documentation

FAIR Data Point (FDP) exposes the following endpoints (URL paths):

Endpoint	GET	POST	PUT	DELETE
fdp	Output fdp metadata	Create new fdp metadata	Update fdp metadata	Not Allowed
catalog	Output all catalog IDs	Create new catalog metadata	Not Allowed	Not Allowed
dataset	Output all dataset IDs	Create new dataset metadata	Not Allowed	Not Allowed
distribution	Output all distribution IDs	Create new distribution metadata	Not Allowed	Not Allowed
catalog/<catalogID>	Output <catalogID> metadata	Not Allowed	Update <catalogID> metadata	Remove <catalogID> metadata
dataset/<datasetID>	Output <datasetID> metadata	Not Allowed	Update <datasetID> metadata	Remove <datasetID> metadata
distribution/<distributionID>	Output <distributionID> metadata	Not Allowed	Update <distributionID> metadata	Remove <distributionID> metadata

Access endpoints to request metadata programmatically

FDP: curl -iH 'Accept: text/turtle' [BASE URL]/fdp

Catalog: curl -iH 'Accept: text/turtle' [BASE URL]/catalog/catalog01

Dataset: curl -iH 'Accept: text/turtle' [BASE URL]/dataset/dataset01

Distribution: curl -iH 'Accept: text/turtle' [BASE URL]/distribution/dist01

FDP supports the following RDF serializations (MIME-types):

• Turtle: text/turtle
• N-Triples: application/n-triples
• N3: text/n3
• RDF/XML: application/rdf+xml
• JSON-LD: application/ld+json
