DynamoDB tables

Standard Config Table Per Service

Configuration tags

{
	configKey: "MediaGraphServiceName"
	configTag: "MediaGraphServiceName"
	configValue: xxx // eg: "MediaGraph"
}

{
	configKey: "TranslationGraphServiceName"
	configTag: "TranslationGraphServiceName"
	configValue: xxx // eg: "TranslationGraph"
}

LogicalResults

Stores results for any requests to perform logical searches on media links

{
	resultId: xxx // eg: filterMainId for a single logical element
	dataId: xxx // one mediaLinkId
}

• partition key: resultId
• sort key: dataId

Basic node schemas

Schema comes from BasicNodeSchemaLib

1. mediaLinkPropertyLabel

Complex Filter requests

{
	filterType: "mediaLink"
	type: "group",
	elements:
	[
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "mediaLinkProperty",
				type: "group",
				elements: 
				[
					{
						type: "logical",
						logicalTag: "propertyLabelId",
						comparison: "equals",
						value: "lksdflkfldfgldfkgjldfg"
					},
				]
			}
		},
	]
}

- filterType: "mediaLinkProperty" sends to MediaLink service and returns resultType = "mediaLinkProperty" - by splitting into a lower level filter_type we can cache results at that level then use translateIds system to change to mediaLinkIds, this could be useful in the future when we want propertyIds to translate to other filterTypes

{
	filterType: "mediaLink"
	type: "group",
	elements:
	[
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "mediaLinkPropertyTranslation"
				type: "group",
				elements: 
				[
					{
						type: "logical",
						logicalTag: "textTag_languageId_text",
						resultType: "mediaLinkProperty",
						textTag: "mediaLinkPropertyValue",
						languageId: "en",
						text: "Blue",
						subjectIdentifierPropertyName: "propertyId",
						caseSensitive: true
					},
				]
			}
		},
		...
	]
}

- mediaLinkPropertyTranslation filterType sends logical element directly to Translation service, which recognises logicalTag: "textTag_languageId_text" and caches the subjectIdentifierPropertyName value in its LogicalResults table
