Put together a landing page for Slinky with example queries

[amoeba]

Exposing a SPARQL endpoint for Slinky would be fun but it's not all that useful to anyone but ourselves. And even then.

It'd be better if we had a concise showcase of what Slinky is and what it can do and this could similar to what we did for GeoLink: http://data.geolink.org/.

Today we put together a quick list of interesting example queries that could go on this page:

• Show me all datasets that have measurements of sea-surface temperature
• Show me all datasets that have measurements of carbon-dioxide flux from Alaska
• Show me all datasets created by Ted Schuur
• Show me all datasets that have the term “ecosystem” in their Abstract or Title
• Show me all datasets about Salmon that have both weight and length measurements (ideally in a tuple)
• Who’s doing research in the arctic? Which organizations?

[I don't think we have an issue for this specifically but let me know if that's wrong]

On a related note, I just found https://github.com/aws/graph-notebook which might be useful somewhere.

One option is to use the yasgui module for the query page, which is used on the gnis-ld queries page. It's really easy to set up and should work on any framework that supports npm or yarn. I think the bigger questions are which technology we'd want to go with. I feel pretty biased towards hugo because it's well supported, uses pretty sane templating & css languages, and is used in other DataONE projects.

Relating this to #11 because depending on the web framework we choose we can do a reverse proxy to Virtuso.

I'm imaging this would be deployed at api.dataone.org/slinky and the sparql endpoint at api.dataone.org/slinky/sparql.

An alternative would be to give the sparql endpoint priority at api.dataone.org/slinky/sparql (since api.dataone.org/slinky is Virtuoso Conductor), which might feel more APIish and put the query examples at api.dataone.org/slinky/examples or api.dataone.org/slinky/queries.

We now have a minimal landing page with a few example SPARQL queries. The current queries aren't too interesting, so we should leave this open and add a few of the ones Bryce mentioned above.
