DC 5.8 SDK 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.

   var assetSearchService = app.Services.GetRequiredService<IAssetSearchService>(); var metadataValueService = app.Services.GetRequiredService<IMetadataValueService>(); var asset = await assetSearchService.GetAsset(75); var metadataUpdate = new BitMetadataUpdate { Value = true, TargetItemIds = new HashSet<int> { asset.ItemId }, MetaFieldItemGuid = Guid.Parse("<GUID of Metafield>") }; await metadataValueService.ApplyUpdate<MetadataUpdate>(new[] { metadataUpdate});

    

2. INT
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of IntMetadataUpdate. 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.

   var assetSearchService = app.Services.GetRequiredService<IAssetSearchService>(); var metadataValueService = app.Services.GetRequiredService<IMetadataValueService>(); var asset = await assetSearchService.GetAsset(75); var metadataUpdate = new IntMetadataUpdate { Value = 99, TargetItemIds = new HashSet<int> { asset.ItemId }, MetaFieldItemGuid = Guid.Parse("<GUID of Metafield>") }; await metadataValueService.ApplyUpdate<MetadataUpdate>(new[] { metadataUpdate});

    

3. STRING
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of StringMetadataUpdate. 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.

   var assetSearchService = app.Services.GetRequiredService<IAssetSearchService>(); var metadataValueService = app.Services.GetRequiredService<IMetadataValueService>(); var asset = await assetSearchService.GetAsset(75); var metadataUpdate = new StringMetadataUpdate { Value = "Update metafield string", TargetItemIds = new HashSet<int> { asset.ItemId }, MetaFieldItemGuid = Guid.Parse("<GUID of Metafield>") }; await metadataValueService.ApplyUpdate<MetadataUpdate>(new[] { metadataUpdate});

    

4. COMBOVALUE
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of ComboValueMetadataUpdate. The TargetItemIds is the itemId of the asset we just fetched. The MetaFieldItemGuid is the GUID of the metafield you wants to update.
   The ComboValue can either be set to an existing combovalue or create an new combovalue.
   new ExistingCombo(50170) or new DynamicCombo { Label = "test" , OptionValue = "test" }.
   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.

    

5. MULTICOMBOVALUE
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of MultiComboValueMetadataUpdate. The TargetItemIds is the itemId of the asset we just fetched. The MetaFieldItemGuid is the GUID of the metafield you wants to update.
   The ComboValues can either be a set of existings combovalues or create an new combovalues.
   new ExistingCombo(50170) or new DynamicCombo { Label = "test" , OptionValue = "test" }.
   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.

    

6. DATETIME
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of DateTimeMetadataUpdate. 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.

    

7. TREE
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of TreeMetadataUpdate. The TargetItemIds is the itemId of the asset we just fetched. The MetaFieldItemGuid is the GUID of the metafield you wants to update.
   The TreeValues can eather be a set of existings ExistingTreeNode or create new treenodes by using the DynamicTopDownTreeNode.
   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.

    

8. EDITCOMBOVALUE
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of EditComboValueMetadataUpdate. 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.

    

9. EDITMULTICOMBOVALUE
   Use the Digizuite service IAssetSearchService and IMetadataValueService.
   First we fetch the asset. Then creates a new instance of EditMultiComboValueMetadataUpdate. 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.
