tar_url and kgx assumption

[cmungall]

Current:

tar_url: https://kg-hub.berkeleybop.io/kg-covid-19/current/kg-covid-19.tar.gz

I believe this is implicitly a kgx tar, containing nodes and edges tsv

It would be good not to box ourselves in. We may want to later provide a sqlite instance. And although our own tools don't consume it, I think rdfstar could be broadly very impactful.

We could bundle this all in the tar, but we don't want people to download unecessary artefacts

We could have distinct keys:

• kgx_tgz
• kgx_sqlite
• rdfstar
• kgmeta

or we could do it the same way as the obo metadata where each 'product' is an object

@cmungall seems reasonable to capture KGs like rdfstar, even if we can't yet consume it

kgmeta

I don't understand this one - what does that kgmeta key refer to?

[cmungall]

kgmeta would be a summary of the graph in "kgmeta" format as produced by kgx @sierra-moxon can provide more deets
