handling multi-language values in JSON-LD (how to index in Solr), and how to display these in the front-end search results

[jmckenna]

• CIOOS partner's JSON-LD has multiple languages for many of its properties, here is a snippet:

      "keywords": [
          {
            "@language": "en",
            "@value": "watershed"
          },
          {
            "@language": "fr",
            "@value": "bassin versant"
          }
      ],
      "name": [
        {
          "@language": "fr",
          "@value": "Projet REKEAU - Entreprises manufacturi\u00e8res (2019)"
        },
        {
          "@language": "en",
          "@value": "REKEAU Project - Manufacturing (2019)"
        }
      ],

• both our back-end indexing process, as well as our front-end UI should be adapted to handle multiple languages
  • the ODIS graph could be adapted to handle multiple languages, and then those changes could be pushed into the Solr index
  • likely the front-end UI should allow users to filter results by language also
