我想使用核心服务为组件元数据设置多媒体链接。

我正在尝试如下所示，出现 xml 验证错误。你能帮忙吗？

        ComponentData comp = client.Read(compid, readoption) as ComponentData;
        comp = client.TryCheckOut(compid, readoption) as ComponentData;

        string newxml = @"<Metadata xmlns=""uuid:5880d67f-13f7-4632-8c33-dcfd9c1437ed"">
                          <meta>
                          <mmlink>tcm:22-5678</mmlink>        

                          </metad>
                          </Metadata>";

        comp.Metadata = newxml;

        client.Save(comp, readoption);
        client.CheckIn(comp.Id, readoption);

你应该xlink:href在这里设置：

<mmlink xlink:type="simple" xlink:href="tcm:2-146" 
        xmlns:xlink="http://www.w3.org/1999/xlink"></mmlink>

解决此类问题的最简单方法是创建一个包含相关字段和相应组件的组件模式。然后，您将通过探索组件 XML 找到答案

多媒体链接的方法与组件链接的方法相同。它也适用于内容和元数据字段：此示例在文件夹元数据中设置 mm 组件链接，其中 md 模式包含一个名为“versioned_component”的可嵌入字段，其中包含一个名为“component”的字段，这是一个多媒体组件链接字段：

this.OpenSession();
try
{
    //itemUri is the MM Component uri
    var currentItem = (ComponentData)session.Read(itemUri, new ReadOptions());
    LinkToRepositoryData ltrd = currentItem.LocationInfo.ContextRepository;
    var pd = (PublicationData)session.Read(ltrd.IdRef, new ReadOptions());
    String currentPublicationWebdavURL = pd.LocationInfo.WebDavUrl;
    String schemaUri = string.Format(FOLDER_MD_SCHEMA_WEBDAVURL, 
                          HttpUtility.UrlDecode(currentPublicationWebdavURL));

    //schemaUri = HttpUtility.UrlEncode(schemaUri);
    var sd = (SchemaData)session.Read(schemaUri, new ReadOptions());
    FolderData folder = new FolderData();
    folder.Id = TcmUri.UriNull;
    folder.Title = "hidden_" + Guid.NewGuid().ToString();
    var rootFolder = (FolderData)session.Read(
                            currentItem.LocationInfo.OrganizationalItem.IdRef, 
                            new ReadOptions());
    folder.LocationInfo= new LocationInfo()
    {
        OrganizationalItem = new LinkToOrganizationalItemData(){
            IdRef = rootFolder.Id
        }
    };
    folder.MetadataSchema = new LinkToSchemaData()
    {
        IdRef = sd.Id,
    };
    string sMetadata = "<Metadata xmlns=\"{0}\" xmlns:xlink=\"{1}\"> " 
                     + "  <version_component>" 
                     + "    <component xlink:type=\"simple\" " 
                     + "          xlink:href=\"{2}\" xlink:title=\"{3}\" />" 
                     + "  </version_component> " 
                     + "</Metadata>";
    sMetadata = string.Format(sMetadata, sd.NamespaceUri, 
                              Tridion.Constants.XlinkNamespace, 
                              currentItem.Id.ToString(), currentItem.Title);
    folder.Metadata = sMetadata;
    folderUri = session.Save(folder, new ReadOptions()).Id.ToString();
    return folderUri;
}
finally {
    this.CloseSession();
}

希望这也有帮助，
