logic

Main job is to create statements in graph database. Expects subject vertex to already exist (does not create subject with label/properties).

1. create vertex by invoking NPM module - izara-shared#neptuneGraphSharedLib.createVertex
   1. vertexId: vertexId
   2. vertexLabel: 'vertexLabel'
   3. vertexProperties: 'vertexProperties'

CreateTranslation

/**
 * Create a new translation for a source object
 * @param {string} subjectId
 * @param {string} translationLabel
 * @param {string} languageCode
 * @param {string} userId
 *
 * @returns {Object[]} ?translation vertex id?

Main job is to create statements in graph database. Expects subject vertex to already exist (does not create subject with label/properties).

1. create ids for translation vertex:
   1. const objectId = NPM module - izara-shared#neptuneGraphSharedLib.createVertexId('translation_', {random uuid})
   2. const objectLabel = translationLabel + Translation
2. create id for PossiblyTranslatesTo edge:
   1. const possiblyTranslatesToEdgeId = subjectId + '_Possible' + translationLabel + '_' + languageCode + '_' + objectId
3. create PossiblyTranslatesTo graph statement by invoking NPM module - izara-shared#neptuneGraphSharedLib.createRelationshipStatement
   1. subjectId: subjectId
   2. edgeLabel: 'PossiblyTranslatesTo'
   3. edgeId: possiblyTranslatesToEdgeId
   4. objectId: objectId
   5. objectLabel: 'PossiblyTranslatesTo'
   6. objectProperties:
      1. languageCode: languageCode
4. create id for TranslatesTo edge:
   1. const translatesToEdgeId = subjectId + '_' + translationLabel + '_' + languageCode + '_' + objectId
5. create TranslatesTo graph statement by invoking async NPM module - izara-shared#neptuneGraphSharedLib.createRelationshipStatement
   1. subjectId: subjectId
   2. edgeLabel: 'TranslatesTo'
   3. edgeId: translatesToEdgeId
   4. objectId: objectId
6. create id for DefaultTranslatesTo edge:
   1. const defaultTranslatesToEdgeId = subjectId + '_Default' + translationLabel + '_' + objectId
7. create DefaultTranslatesTo graph statement by invoking async NPM module - izara-shared#neptuneGraphSharedLib.createRelationshipStatement
   1. subjectId: subjectId
   2. edgeLabel: 'DefaultTranslatesTo'
   3. edgeId: defaultTranslatesToEdgeId
   4. objectId: objectId
8. create ids for user vertex:
   1. const userVertexId = NPM module - izara-shared#neptuneGraphSharedLib.createVertexId('user_', {userId})
9. create id for translation CreatedBy edge:
   1. const createdByEdgeId = objectId + '_CreatedBy_' + userVertexId
10. create CreatedBy graph statement by invoking async NPM module - izara-shared#neptuneGraphSharedLib.createRelationshipStatement
    1. subjectId: objectId
    2. edgeLabel: 'CreatedBy'
    3. edgeId: createdByEdgeId
    4. objectId: userVertexId
