data360-schema-get Skill

Overview

This skill retrieves Data Lake Object (DLO) and Data Model Object (DMO) schema information from Salesforce Data Cloud using the SSOT REST API. It can list all DLOs or DMOs in an org, or retrieve detailed schema for a specific DLO or DMO.

When to Use

• User wants to see all DLOs or DMOs in a Data Cloud org
• User needs field schema for a specific DLO or DMO
• User is exploring Data Cloud data structures
• User needs to understand DLO or DMO field types and metadata

Prerequisites

• SF CLI installed and authenticated to target org
• Org has Data Cloud enabled
• User has appropriate Data Cloud permissions

Skill Execution

Parameters

1. **org_alias** (required): The SF CLI org alias (e.g., 'afvibe', 'myorg') 2. **dlo_name** (optional): Specific DLO developer name (e.g., 'Employee__dll') 3. **dmo_name** (optional): Specific DMO developer name (e.g., 'Individual__dlm')

Step 1: Discover Connected Org

First, run `sf org list` to find out which org is connected and extract the alias to use for all subsequent calls:

sf org list

Example output:

┌────┬───────┬──────────────────────────┬────────────────────┬───────────┐
│    │ Alias │ Username                 │ Org Id             │ Status    │
├────┼───────┼──────────────────────────┼────────────────────┼───────────┤
│ 🍁 │ myorg │ chandresh@afvidedemo.org │ 00DKZ00000b80NT2AY │ Connected │
└────┴───────┴──────────────────────────┴────────────────────┴───────────┘

Extract the **Alias** value (e.g., `myorg`) from the output and use it as the `<org_alias>` for all subsequent calls. Use `--all` to see expired and deleted scratch orgs as well.

Step 2: Validate SF CLI Authentication

Before making API calls, verify the org is connected:

sf org display --target-org <org_alias> --json

If not connected, inform user to run:

sf org login web --alias <org_alias>

Step 3a: Execute DLO Schema Script

The Python scripts are bundled with this skill in the `scripts/` subdirectory.

**To list all DLOs:**

python3 ./scripts/get_dlo_schema.py <org_alias>

**To get specific DLO schema:**

python3 ./scripts/get_dlo_schema.py <org_alias> <dlo_name>

Step 3b: Execute DMO Schema Script

**To list all DMOs:**

python3 ./scripts/get_dmo_schema.py <org_alias>

**To get specific DMO schema:**

python3 ./scripts/get_dmo_schema.py <org_alias> <dmo_name>

Step 4: Present Results

Parse and present the results in a user-friendly format:

**For DLO List:**

• Show DLO name, label, category, and ID
• Indicate total count
• Highlight DLOs with data (totalRecords > 0)

**For DLO Schema:**

• Show basic info (name, label, category, status)
• List all fields with:
• Field name
• Data type
• Primary key indicator
• Nullable status
• Highlight custom fields (exclude system fields like DataSource__c, cdp_sys_*)
• Show record count if available

**For DMO List:**

• Show DMO name, label, category, and ID
• Indicate total count

**For DMO Schema:**

• Show basic info (name, label, category, description)
• List all fields with:
• Field name
• Data type
• Primary key indicator
• Nullable status
• Show dataspace information if available

Step 5: Offer Next Steps

After displaying results, suggest relevant follow-up actions:

• Query data from the DLO
• Create calculated insights
• Build segments
• Set up data streams
• Create DMO mappings

API Endpoints Used

List All DLOs

GET /services/data/v64.0/ssot/data-lake-objects

Response structure:

{
  "dataLakeObjects": [
    {
      "name": "Employee__dll",
      "label": "Employee",
      "category": "Profile",
      "id": "1dlXXXXXXXXXXXXXXX",
      "status": "ACTIVE",
      "totalRecords": 12,
      "fields": [...]
    }
  ],
  "totalSize": 5
}

Get DLO Schema

GET /services/data/v64.0/ssot/data-lake-objects/{dlo_name}

Response structure (same as individual object in list response, but wrapped in paginated format).

List All DMOs

GET /services/data/v64.0/ssot/data-model-objects

Response structure:

{
  "dataModelObjects": [
    {
      "name": "Individual__dlm",
      "label": "Individual",
      "category": "Profile",
      "id": "0dmXXXXXXXXXXXXXXX",
      "fields": [...]
    }
  ],
  "totalSize": 10
}

Get DMO Schema

GET /services/data/v64.0/ssot/data-model-objects/{dmo_name}

Response structure (same as individual object in list response, but wrapped in paginated format).

Error Handling

**Common Issues:**

1. **Org not connected**

• Message: "Org not connected"
• Solution: Ask user to authenticate via SF CLI

2. **DLO not found**

• Message: "DLO 'XYZ__dll' not found"
• Solution: List all DLOs first to verify name

5. **DMO not found**

• Message: "DMO 'XYZ__dlm' not found"
• Solution: List all DMOs first to verify name

3. **Permission issues**

• Message: HTTP 403 errors
• Solution: Verify user has Data Cloud permissions

4. **API version mismatch**

• Current: v64.0
• Solution: Script can be updated for newer API versions

Example Usage

**Example 1: List all DLOs**

User: "Show me all DLOs in afvibe org"

Response:
1. Run sf org list to discover connected org alias
2. Authenticate to afvibe
3. Run: python3 ./scripts/get_dlo_schema.py afvibe
4. Display formatted list of DLOs

**Example 2: Get specific DLO schema**
