[Lds] ideas/recommendations for JSON-LD serializations

[Thomas Gängler]

Hello,

currently, we process some JSON-LD dumps (e.g. ZDB and GND) from data 
available via DNB. Our observations while processing them are following:

1. It would be nice, if you could provide line-delimited JSON [1] 
records (instead of one large JSON object/array (as it is the case right 
now))
2. It would be nice, if the JSON-LD records could be provided in compact 
JSON-LD [2] (instead of the extended format (as it is the case right 
now)) + referenced @context* (instead of inline @context)
3. It would be nice, if the (compact) JSON-LD records contain all 
sub-entities (i.e. there are no separate bnodes, but (if necessary) 
hierarchical entities), cf. [4], [5] or similar (instead of separate 
bnode objects in the same hierarchy level (as it is the case right now))

We believe that all recommended changes will lead to a better usability 
of the provided JSON-LD data. Hence, we and probably other data 
consumers of the DNB datasets will be happy, if you could implement our 
proposed ideas.

Best regards,


Thomas


*) referenced context requires that you probably need to provide/host 
the context documents at DNB (instead of, e.g., ZDB Github account [3])
