Are you tired of scouring through Azure Open AI Service maps, searching for that elusive last modified date? Do you find yourself lost in a sea of data, wondering how to extract the information you need? Fear not, dear reader, for we’ve got you covered! In this comprehensive guide, we’ll take you by the hand and walk you through the process of retrieving the last modified date (and any other date you desire) from Azure Open AI Service maps.
What You’ll Need
- Azure Open AI Service account with access to the desired map
- A basic understanding of Azure Open AI Service maps and their structure
- A willingness to learn and experiment (we promise it’s worth it!)
Understanding Azure Open AI Service Maps
Before we dive into the nitty-gritty of date retrieval, let’s take a step back and review the basics of Azure Open AI Service maps. A map, in this context, refers to a visual representation of data, comprising nodes, edges, and properties. These properties can include anything from metadata to custom attributes, and yes, even dates!
Map Structure
{ "nodes": [ { "id": "node1", "properties": { "name": "Node 1", "lastModifiedDate": "2022-01-01T12:00:00.000Z" } }, { "id": "node2", "properties": { "name": "Node 2", "createdDate": "2022-01-02T12:00:00.000Z" } } ], "edges": [ { "id": "edge1", "source": "node1", "target": "node2", "properties": { "type": "RELATIONSHIP" } } ] }
In the above example, we have a simple map with two nodes and one edge. Each node has properties, including a name and a date (either last modified or created). We’ll focus on extracting these dates in the following sections.
Method 1: Using the Azure Open AI Service API
The Azure Open AI Service API provides a convenient way to retrieve map data, including properties and dates. We’ll use the GET /maps/{mapId}
endpoint to fetch the entire map, and then parse the response to extract the desired dates.
Step 1: Authenticate and Obtain an Access Token
Before making API calls, you’ll need to authenticate and obtain an access token. You can do this using the Azure Open AI Service SDK or by following the official documentation.
Step 2: Make the API Call
curl -X GET \ https://api.azure.ai/ maps/{mapId} \ -H 'Authorization: Bearer {accessToken}' \ -H 'Content-Type: application/json'
Replace {mapId}
with the ID of your desired map, and {accessToken}
with the obtained access token.
Step 3: Parse the Response
The API response will contain the entire map data. You can parse this response using your preferred programming language to extract the last modified date (or any other date) from the node properties.
const response = await axios.get(`https://api.azure.ai/maps/{mapId}`, { headers: { Authorization: `Bearer ${accessToken}`, 'Content-Type': 'application/json' } }); const nodes = response.data.nodes; const lastModifiedDate = nodes[0].properties.lastModifiedDate; console.log(lastModifiedDate); // Output: 2022-01-01T12:00:00.000Z
Method 2: Using Azure Open AI Service SDKs
Azure Open AI Service provides SDKs for various programming languages, making it easier to interact with the service and retrieve map data. We’ll use the JavaScript SDK as an example, but the process is similar for other languages.
Step 1: Install the SDK
npm install @azure/ai-ml
Step 2: Import the SDK and Create a Client
const { MapsClient } = require('@azure/ai-ml'); const mapsClient = new MapsClient({ accessToken });
Step 3: Get the Map Data
const mapData = await mapsClient.getMap({ mapId });
Step 4: Extract the Desired Date
const nodes = mapData.nodes; const lastModifiedDate = nodes[0].properties.lastModifiedDate; console.log(lastModifiedDate); // Output: 2022-01-01T12:00:00.000Z
Method 3: Using Azure Open AI Service Workbooks
Azure Open AI Service Workbooks provide an interactive environment for data exploration and visualization. You can use Workbooks to retrieve and display dates from your maps.
Step 1: Create a New Workbook
In the Azure Open AI Service portal, navigate to the Workbooks section and create a new Workbook.
Step 2: Add a Map Data Source
In the Workbook, add a new data source and select “Map” as the type. Enter your map ID and authenticate using your access token.
Step 3: Add a Table Visual
Add a new table visual to the Workbook and configure it to display the node properties. You can then filter or sort the table to focus on the desired dates.
Step 4: Extract the Desired Date
Using the table visual, you can extract the last modified date (or any other date) from the node properties.
Node ID | Name | Last Modified Date |
---|---|---|
node1 | Node 1 | 2022-01-01T12:00:00.000Z |
node2 | Node 2 | 2022-01-02T12:00:00.000Z |
In the above example, we’ve extracted the last modified date from the node properties using the Workbooks table visual.
Conclusion
Retrieving the last modified date (or any date) from Azure Open AI Service maps is a breeze, thanks to the various methods outlined in this guide. Whether you prefer using the API, SDKs, or Workbooks, you now have the tools and knowledge to unlock the secrets of your maps. Remember to experiment and adapt these methods to your specific use case, and don’t hesitate to reach out if you have any further questions.
Happy mapping!
Frequently Asked Questions
-
What if I have a large map with thousands of nodes?
In this case, you may want to consider using the Azure Open AI Service API’s pagination feature to retrieve nodes in batches, reducing the load on your system.
-
Can I use Azure Open AI Service Workbooks for large-scale data analysis?
While Workbooks are great for visualization and exploration, they may not be suitable for large-scale data analysis. Consider using the API or SDKs for more complex data processing tasks.
-
What if I encounter permissions issues while accessing the map data?
Make sure you have the necessary permissions and access controls in place to retrieve the map data. Consult the Azure Open AI Service documentation for more information on authentication and authorization.

Frequently Asked Question
Get ready to unravel the mystery of fetching dates in Azure Open AI Service maps!
How do I retrieve the lastModifiedDate from an Azure Open AI Service map?
You can fetch the lastModifiedDate by using the `$metadata` system property in your Azure Open AI Service map. Specifically, you can use the `$metadata.lastModifiedDate` syntax to retrieve the date.
Can I access other dates besides lastModifiedDate in Azure Open AI Service maps?
Yes, you can! Azure Open AI Service maps provide various date-related properties. For instance, you can use `$metadata.createdDate` to fetch the creation date or `$metadata.updatedDate` to retrieve the last updated date.
How do I format the dates retrieved from Azure Open AI Service maps?
You can use the `datetime` function in Azure Open AI Service maps to format the dates according to your needs. For example, `datetime($metadata.lastModifiedDate, ‘MM/dd/yyyy hh:mm:ss tt’)` will format the lastModifiedDate in the specified format.
Can I perform date-based calculations in Azure Open AI Service maps?
Absolutely! Azure Open AI Service maps support various date-related functions, such as `datetimeDiff` and `datetimeAdd`. These functions enable you to perform calculations like finding the difference between two dates or adding a specified interval to a date.
Are there any limitations to working with dates in Azure Open AI Service maps?
Yes, there are some limitations. For instance, Azure Open AI Service maps might not support certain date formats or locale-specific date representations. Additionally, performance might be affected when dealing with large date ranges or complex date calculations.
