gs1:masterData examples

• 214 discusses the current 3 MasterData examples: only 1 is any good, and needs to be made more precise

• I see in 2021_03_08b GS1-White-Paper-On-demand-master-data.docx a great example (sec 2) of linkType=gs1:masterData response about a product (gs1:Seafood) returned as JSON-LD

• Can we add more examples, eg of gs1:Organization (pgln), gs1:Place (sgln), a rail vehicle (giai)? Ideally we should cover all classes in Ontology/identifier-object-mapping.md
• We should show all examples both as JSONLD, and also Turtle

We can do these examples in this repo.

But in which workgroup does this work belong, and if it will be reflected in any documents, which docs are those?

We can definitely add further examples to the draft white paper. I started it as something emerging from the EPCIS / CBV 2.0 MSWG as a result of recent discussions about modernising access to master data. Phil added some improvements. There is a possibility (still being discussed) that it could be published as a Technical Bulletin of the GS1 Architecture Group. Phil and I have felt that there has not yet been sufficient explanation to the wider GS1 community about how GS1 Digital Link can work with Linked Data, the GS1 Web vocabulary and schema.org
