Lambda Taggable Elasticsearch Indexer

Listen for updates in tags in the numo-taggy/ci S3 bucket and update ElasticSearch record.

The data inserted to ElasticSearch will be used to autocomplete at the tagging system and isearch-ui.

Tags will be created as follows:

{
  tagid: 'tagid',
  name: 'market value',
  label: 'official tag name',
  context: '`taggy` for tagging system and `market:language` for isearch-ui'
}

A tag will be created for each value in the markets property specified in the input data plus an additional tag with taggy context for taggable-ui.

For example, with the following input:

{
  "_id": "geo:geonames.1609350",
  "displayName": "Bangkok",
  "location": {
    "lat": "13.75398",
    "lon": "100.50144"
  },
  "tags": [
    {
      "node": "geo:geonames.1608132",
      "edge": "LOCATED_IN",
      "displayName": "Changwat Nonthaburi",
      "source": "geonames",
      "active": true
    }
  ],
  "markets": {
    "dk": {
      "da": {
        "label": "Bangkok",
        "values": [
          "Bangkok",
          "Vangkok"
        ]
      }
    },
    "de": {
      "de": {
        "label": "Bangkok",
        "values": [
          "Bangkok"
        ]
      }
    },
    "gb": {
      "en": {
        "label": "Angels land",
        "values": [
          "The City of Angels"
        ]
      },
      "es": {
        "label": "Bangkok",
        "values": [
          "Bangkok"
        ]
      }
    },
  }
}

The following tags would be created:

{
  tagid: 'geo:geonames.1609350',
  name: 'Bangkok',
  label: 'Bangkok',
  context: 'dk:da'
}
 
{
   tagid: 'geo:geonames.1609350',
   name: 'Vangkok',
   label: 'Bangkok',
   context: 'dk:da'
}
 
{
   tagid: 'geo:geonames.1609350',
   name: 'Bangkok',
   label: 'Bangkok',
   context: 'de:de'
}
 
{
   tagid: 'geo:geonames.1609350',
   name: 'The city of Angels',
   label: 'Angels land',
   context: 'gb:en'
}
 
{
   tagid: 'geo:geonames.1609350',
   name: 'Bangkok',
   label: 'Bangkok',
   context: 'gb:es'
}
 
{
   tagid: 'geo:geonames.1609350',
   name: 'Bangkok',
   label: 'Bangkok',
   context: 'taggy'
 }
