[DISCUSS] Using CovJSON-LD #85

Closed lewismc closed 5 years ago

lewismc commented 7 years ago

Hi Folks, What ways do people currently have for embedding the LD aspects within CovJSON? I have been over on the pycovjson project and using it nicely now to create a proof of concept for improved visualization of our earth science datasets. I would really like to be able to infer SPO relationships from our CovJSON however and would like to learn how people are currently genrating this in an automated fashion.

Don't expect too much support for these things at this time. CovJSON allows you to embed LD via JSON-LD in a controlled fashion. Please have a look at the Extensions section of the spec and the JSON-LD section following it. What kind of linked data (ontologies) do you want to embed? If you don't have a clear idea about that yet I wouldn't invest huge amounts of time but approach it from a practical point of view and only adding the extra metadata bits that you really need in order for your web application to work and (if you intend to share the data with the wider public) for others to benefit from the extra metadata.

Yes, what kind of SPO relationships are you looking at? From the existing CovJSON information or would you like to add more information as extensions? There is limited support for converting CovJSON to triples via JSON-LD, but not all information will be converted. @letmaik is there a copy of our GIScience paper online that Lewis could read?

Here's the GIScience paper: http://stko.geog.ucsb.edu/sdw16/paper_5.pdf

I am advocating that the sweet ontologies be hosted at ESIP and governed there. I will submit a PR for adding sweet.jpl.nasa.gov to the list of standard prefixes in CovJSON. I would therefore begin by augmenting PO.DAAC CovJSON-LD with domainType'e defined within sweet. Thank you both kindly for the links and info. If your you have a DOI for the paper that would be great. Thanks

Do you really mean domainTypes or do you mean observedProperties?
