Information provided includes the SKU, network configuration, and upcoming maintenance events.

For a complete list of the data that is available, see metadata APIs. The endpoint is available at a well-known non-routable IP address This service is generally available in all Azure Regions. It regularly receives updates to expose new information about virtual machine instances.

This page reflects the up-to-date metadata APIs available. The service is available in generally available Azure regions. You can see the newest versions listed in this availability table.

As newer versions are added, older versions can still be accessed for compatibility if your scripts have dependencies on specific data formats. When you query the Instance Metadata Service, you must provide the header Metadata: true to ensure the request was not unintentionally redirected.

Access all data categories for a virtual machine instance using the following request:. However, different APIs return data in different formats if requested. The following table is a reference of other data formats APIs may support. To access a non-default response format, specify the requested format as a query string parameter in the request. For example:. The Instance Metadata Service endpoint is accessible only from within the running virtual machine instance on a non-routable IP address.

In addition, any request with a X-Forwarded-For header is rejected by the service. Requests must also contain a Metadata: true header to ensure that the actual request was directly intended and not a part of unintentional redirection. All following example responses are pretty-printed for readability. Part of the scenario served by Instance Metadata Service is to provide guarantees that the data provided is coming from Azure.

We sign part of this information so that marketplace images can be sure that it's their image running on Azure. The following example responses are pretty-printed for readability. Api-version is a mandatory field. Refer to the service availability section for supported API versions. Nonce is an optional digit string. Due to IMDS's caching mechanism, a previously cached nonce value may be returned.

The signature blob is a pkcs7 signed version of document. It contains the certificate used for signing along with the VM details like vmId, sku, nonce, subscriptionId, timeStamp for creation and expiry of the document and the plan information about the image.

The plan information is only populated for Azure Market place images. The certificate can be extracted from the response and used to validate that the response is valid and is coming from Azure. The response is a JSON string.

The following example response is pretty-printed for readability. As a service provider, you may require to track the number of VMs running your software or have agents that need to track uniqueness of the VM. For certain scenarios, placement of different data replicas is of prime importance.

You can also use Availability Zones for the instances to make these decisions. You can query this data directly via the Instance Metadata Service. As a service provider, you may get a support call where you would like to know more information about the VM.By submitting your feedback, you accept the Adobe Terms of Use. Show Menu. Delivering Content Fragments. Adobe Experience Manager AEM Content Fragments are text-based editorial content that may include some structured data elements associated but considered pure content without design or layout information.

Content Fragments are typically created as channel-agnostic content, that is intended to be used and re-used across channels, which in turn wrap the content in a context-specific experience. Content Fragments, independent of layout, can be used directly in AEM Sites with Core Components or can be delivered in a headless manner to downstream channels.

This video series covers the delivery options for using Content Fragments. Details about defining and authoring Content Fragments can be found here. Content Fragments. Using Content Fragments in Web pages Your browser does not support the iframe element. The Content Fragment List Component is a new component that allows an author to define a query that will dynamically populate the page with a list of Content Fragments.

First introduced in AEM 6. The Content Services framework provides more flexibility and options as to what data gets exposed. A typical use case is ingesting 3rd party content on an AEM author environment. Additional Resources Authoring Content Fragments. To download and install the package below on an AEM 6.

I need to extract the assets' metadata, and print them on my page, I'm new in AEM and i don't know how to do it.

I'm thinking about create a component by I don't know what i sholud write inside. Usecase : An asset is displayed in page and it will have link MetadataInfo. Once I click on the MetadataInfo link, it will re-direct to metadatainfo page which will display all the metadata information of the asset.

Once the link is clicked it redirects to url of the metadatinfo page appended with parameter "assetpath" containing the asseturl. Created a servlet which will get the parameter "path" containig the asseturl as string and convert it to a resource. Will resolve it to resource till the metadata node of the asset. By Value map got all the properties of metadata and created hashmap storing all the metadata properties as Key:Value pair. Learn more. How to display Asset Metadata on a Page?

Sometimes we are faced with a situation where we need to pass data from one workflow step to the another. Please note that only primitive data types like Integer, String etc. If you have a requirement to pass non-primitive data then use the byte[] array. Caution: If the data to be passed is too large, refrain passing InputStream. Instead, a better approach is to save the data in a JCR node in the step and retrieve it from the JCR node in a later step.

A MetaDataMap is the data structure which acts as a value map and allows users to set and get data among the steps. Code example Let's see a code example to demonstrate this concept.

Here we will be using two process steps.

In the first, we will be passing data and in the second, we will be retrieving it. Component; import org. Logger; import org. LoggerFactory; import com. WorkflowException; import com. WorkflowSession; import com. WorkItem; import com. WorkflowProcess; import com.

Some authors advise to use JCR API like more performance optimized and the rest are on the side of Apache Sling because it's faster to write and far more readable and maintainable in the long run.

And I had some questions:. Which API should I use and when? It is then important however to know the border between these two scenarios.

Maciej notices it is around 1ms difference for opening the regular AEM page without taking any caching into account. Taking care of the performance is totally unnecessary in that case.

We should instead focus on writing code that is readable, understandable, reduced to the minimum and reusing already existing APIs, frameworks, util classes that are covered already by proper unit tests and peer reviewed, rather than reinventing the wheel from the beginning. Base on that, we should also prefer AEM layer over Sling layer.

From my experience, I would say that JCR should be utilized in few scenarios, mainly when traversing of a large amount of data of CRX database and it cannot be achieved by any searching API. However, the most important thing is to not mix both abstract layers in your implementation.

In this scenario, obviously the Sling API's win by a huge margin on the ease of access and usability. Approach: In such a requirement where you need to do certain one-time changes to your JCR repository, you should use the JCR APIs by creating a Standalone Java Application to perform such tasks instead of creating an unnecessary component, its controller, an unnecessary page to put this component and then using the Sling API's in the controller to perform these tasks.
