Improve distinction and links between pre-prints, published articles

[willu47]

At the moment, there is no good distinction between pre-prints, published articles, and now clear links between the various elements which comprise a study. It would be great if we could include the links between entities so that the various artefacts could be better represented on the research index:

pre-print
article
dataset
model
software

The new v3 openaire API provides a type key under instance e.g.

token = <personal token>
api_url = "https://api.openaire.eu/graph/researchProducts"
params = {'pid': "10.5281/zenodo.10848127"}
headers = { "Authorization": f"Bearer {token}" }
response = requests.get(api_url, params, headers=headers)
for instance in results[0]['instance']:
    print(instance['type'], instance)

produces

Article {'pid': [{'scheme': 'doi', 'value': '10.1016/j.erss.2024.103821'}], 'license': 'CC BY', 'type': 'Article', 'url': ['https://doi.org/10.1016/j.erss.2024.103821'], 'publicationDate': '2024-12-01', 'refereed': 'peerReviewed'}

Links between entities can be further enriched using the ScholExplorer API provided by OpenAire like so:

response = requests.get("https://api.scholexplorer.openaire.eu/v3/Links", params = {'targetPid': "10.5281/zenodo.10848127"})
for result in response.json()['result']:
    print(result['RelationshipType']['Name'], result['source']['Type'], result['target']['Type'], result['source']['Identifier'][0]['ID'], result['source'].keys())
