Best practice for publication of dataset as part of an external publication #400

Open jucajuca opened 3 weeks ago

jucajuca commented 3 weeks ago

Dear SEMIC,

There is an ongoing discussion about the best practice for the isReferencedBy property. The specification allows any rdf:ressource for this property.

Some data providers provide an IRI for this property, yet others think that this should be a foaf:Document (example below). There are even more possibilities and this makes the handling of the data difficult.

Do you have plans to specify what kind of data should be entered in this property? Or are there best practices regarding this?

In the activity-based approach, (i) an emission factor is provided for CO2 emissions (in tonnes of CO2/MWh) only, and (ii) another for GHG emissions, namely CO2, CH4 and N2O (in tonnes of CO2-eq/MWh); in the LC approach (iii) an emission factor is provided accounting for GHG emissions, namely CO2, N2O and CH4 (in tonnes of CO2-eq/MWh), including upstream (supply chain) emissions.\n\nFurther details on the data and methodology used to calculate the emission factors presented in this version can be found in Bastos, Monforti-Ferrario and Melica (2024)."@en;

@jucajuca - The example provided follows the DCAT-AP-JRC extension, where the range defined for dct:isReferencedBy is foaf:Document. However, the RDF representation shown in your example above is the result of a legacy publishing mechanism which is currently being revised. Below is an example of the updated RDF:
