Usecases - Asset metadata update

In the following we show how you can update the different metafield types on an asset.

1. BIT
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of BitMetadataUpdate. The TargetItemIds is the itemId of the asset we just fetched. The MetaFieldItemGuid is the GUID of the metafield you wants to update. As you can see in the ApplyUpdate, it takes a list of updates. So you have the options to bulk update metadata for an asset.

   Code Block

   var assetSearchService = app.Services.GetRequiredService<IAssetSearchService>(); var metadataValueService = app.Services.GetRequiredService<IMetadataValueService>(); var asset = await assetSearchService.GetAsset(75); var bitMetadataUpdate = new BitMetadataUpdate { Value = true, TargetItemIds = new HashSet<int> { asset.ItemId }, MetaFieldItemGuid = Guid.Parse("7072a817-abdf-469b-9042-f281189d52fa") }; await metadataValueService.ApplyUpdate<MetadataUpdate>(new[] { bitMetadataUpdate });
