Analyze Hugging Face Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live Hugging Face data. The CData API Server generates an OData API for Hugging Face, which is natively consumable in Reveal. In this article, we walk through connecting to Hugging Face in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to Hugging Face from API Server

CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open API Server and click Settings -> Connection -> Add Connection 👁 Adding a connection
   
2. Select "Hugging Face" 👁 Selecting a Connector (Salesforce is shown).
   
3. Enter the necessary authentication properties to connect to Hugging Face.

   HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

   Using API Key Authentication

   To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

   1. Log in to your HuggingFace account at https://huggingface.co
   2. Navigate to Settings > Access Tokens
   3. Click "New token" to create a new access token
   4. Select the appropriate permissions (read or write)
   5. Copy the token value

   After obtaining your access token, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your HuggingFace access token.

   Example connection string

   Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';

Add Hugging Face Resource Definitions in API Server

After connecting to Hugging Face, create Resources, which represent API endpoints for Hugging Face data.

1. Click Settings -> Resources -> Add Resource 👁 Adding a new resource
   
2. Select the Hugging Face connection 👁 Selecting a connection (Salesforce is shown)
   
3. Select the table you wish to retrieve and click Next 👁 Selecting a Table (Salesforce is shown)
   
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

Add an API Server User

Create a User to connect to Hugging Face from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Hugging Face Connection and Resource(s) 👁 Creating a new user
   

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.
