create INCOIS dataset template

[jmckenna]

• this issue will track the development of a dataset JSON-LD template to provide to the INCOIS team
• the current pull request version is just a nicely formatted version of this sample record's JSON-LD as-is: https://incois.gov.in/essdp/ViewMetadata?fileid=524fd72e-6b2f-4025-94ea-361dce0e9165
• possible sections to improve/correct:
  • remove extra comma in PostalAddress (with that change, the template validates)
  • review Keywords syntax with DefinedTerm
  • review creator property (with sub-creator property)
    • is that the correct syntax?

@jmckenna this was helpful: http://blog.schema.org/2014/06/introducing-role.html

It's a little unusual to me, but Role is an intervening Type between a relationship and other entities, and the repetition of the original relation (in this case creator) seems valid. I'd improve it by adding starting and ending dates for the role, but these are optional.

    "creator": [ 
         { 
             "@type": "Role", 
             "roleName": "PrincipalInvestigator", 
             "creator": { 
                 "@type": "Person", 
                 "name": "Mr. Hashim Manjebrayakath", 
                 "email": "anil [ at ] ncaor.gov.in", 
                 "telephone": "+91-832-2525513", 
                 "affiliation": { 
                     "@type": "Organization", 
                     "name": "National Centre for Polar and Ocean Research (NCPOR)" 
                 }, 
                 "address": { 
                     "@type": "PostalAddress", 
                     "addressLocality": "Vasco-da-Gama", 
                     "addressRegion": "Goa", 
                     "postalCode": "403804", 
                     "addressCountry": "IND" 
                 } 
             } 
         } 
     ]

@pbuttigieg my earlier question here to you about Keywords with DefinedTerm is now critical as I tested bringing the INCOIS records into Solr/front-end search, and all of that code does not support keywords with DefinedTerms :(
example:

  "keywords": [
    {
      "@type": "DefinedTerm",
      "name": "Aerosol Forward Scatter",
      "inDefinedTermSet": "https://gcmd.earthdata.nasa.gov/kms/concepts/concept_scheme/sciencekeywords"
    },
    {
      "@type": "DefinedTerm",
      "name": "Aerosol Extinction",
      "inDefinedTermSet": "https://gcmd.earthdata.nasa.gov/kms/concepts/concept_scheme/sciencekeywords"
    },
    {
      "@type": "DefinedTerm",
      "name": "Aerosol Particle Properties",
      "inDefinedTermSet": "https://gcmd.earthdata.nasa.gov/kms/concepts/concept_scheme/sciencekeywords"
    },
    "Mahabaleshwar(1792N",
    "High Altitude Cloud Physics Laboratory"
  ],

INCOIS team is VERY fast to adapt to our recommended changes. So do we: 1) adapt all of our code to handle DefinedTerms in Keywords, or 2) ask INCOIS to change to ______ ?

Need your feedback here @pbuttigieg
