Build a custom discovery provider for Sitecore Content Tagging

Version: 10.4

The discovery provider for Sitecore Content Tagging returns tags based on content from the content provider.

The discovery provider takes a collection of TaggableContent objects as input and returns a collection of TagData objects as output.

This topic describes how to:

Implement a custom discovery provider

To create your own discovery provider:

Implement the Sitecore.ContentTagging.Core.Providers.IDiscoveryProvider interface as illustrated in the following example:

RequestResponse

public class ExampleDiscoveryProvider : IDiscoveryProvider
{
    public IEnumerable<TagData> ProcessContent(IEnumerable<TaggableContent> content)
    {
        var tags = new List<TagData>();
        foreach (var taggableContent in content)
        {
            // cast taggableContent object to concrete type returned by ContentProvider
            // TaggableContent is an abstract class and has no properties
            var stringContent = (StringContent)taggableContent;
            // YOUR PROVIDER LOGIC HERE
            // with provided content (stringContent) your provider should return a response
            // from which you can create TagData objects
            // convert response provided by your provider logic into TagData objects
            TagData item = new TagData
            {
                //TagName = "TAG_NAME"
                //Relevance = 5
            };
            tags.Add(item);
        }
        return tags;
    }
}

Add the discovery provider to the configuration file

To use your provider in the content tagging configuration:

RequestResponse

<contentTagging>
    <providers>
        <discovery>
            <add name="ExampleDiscoveryProvider"
type="Custom.ContentTagging.Core.Providers.ExampleDiscoveryProvider,
Custom.ContentTagging.Core" />
        </discovery>
    </providers>
</contentTagging>
