Analyze Nuclia 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 Nuclia data. The CData API Server generates an OData API for Nuclia, which is natively consumable in Reveal. In this article, we walk through connecting to Nuclia in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to Nuclia 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
2. Select "Nuclia"
3. Enter the necessary authentication properties to connect to Nuclia.

   Using API Key Authentication

   Nuclia uses API key authentication for accessing Knowledge Box data. To obtain an API key:

   1. Log in to the Nuclia Cloud Dashboard at https://nuclia.cloud
   2. Navigate to your Knowledge Box settings
   3. Go to the Service Accounts section
   4. Create a new service account or copy an existing API key

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Nuclia service account API key.
   • KbId: Set this to your Knowledge Box UUID.
   • Zone: Set this to your Nuclia deployment zone (e.g., aws-us-east-2-1).

   Example Connection String

   Profile=C:\profiles\Nuclia.apip;AuthScheme=APIKey;APIKey=your_service_account_key;KbId=your_kb_uuid;Zone=aws-us-east-2-1;
   

   Connecting to Nuclia

   Once the authentication is configured, you can connect to Nuclia and query data from any of the available tables such as Resources, KnowledgeBox, LabelSets, and ProcessingStatus.

   

Add Nuclia Resource Definitions in API Server

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

1. Click Settings -> Resources -> Add Resource
2. Select the Nuclia connection
3. Select the table you wish to retrieve and click Next
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 Nuclia from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the Nuclia Connection and Resource(s)

(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.

Create a Dashboard in Reveal

With the API Server configured, we can visualize Nuclia data in Reveal.

1. Log into Reveal and click Dashboards -> New
2. Click Data Source -> OData Feed
3. Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
4. Select Generic Credentials and specify the API Server username and authentication token
5. Select the entity you wish to visualize
6. Select fields and choose a chart type
