Using Custom Tag Libraries to search for AEM Content Tags

You can create custom tag libraries for Adobe Experience Manager (AEM) and use them to search for AEM content tags. Tags are a quick and easy method of classifying content within your website. In technical terms, a tag is a piece of metadata assigned to a content node within AEM (usually a page). A custom tag library uses an OSGi component. Within the OSGi component, the AEM Tag Manager is used to search for the content tags, For information about the API, see TagManager API.

A custom tag library is implemented as an OSGi bundle that contains a Java class that extendsTagSupport. For information, see Class TagSupport.

You also need to define a tag library descriptor (TLD) file and bundle that within the OSGi bundle. For information, see Tag Library Descriptors.

After you develop an AEM custom tag library, you can invoke its actions from an AEM component. For example, the component can display information about tag usage (for example, the number of times it is used). In this article, a Tags xtype is used to let the author select a tag from an AEM dialog, as shown in the following illustration.

Integrating AEM with Adobe Analytics and Target using DTM

You can create Adobe Experience Manager (AEM) solutions that integrate with these Ditigal Marketing products: Adobe Analytics, Adobe Target, and Dynamic Tag Manager (DTM).

Adobe Analytics is the industry-leading solution that lets digital marketers analyze and optimize integrated data from all online initiatives across multiple marketing channels. It provides marketers with actionable, real-time web analytics intelligence about digital strategies and marketing initiatives.

Adobe Target is a personalization solution that lets you easily identify content through tests that are easy to execute. Therefore, you can deliver the best experience to your web visitors. In this article, personalization of the landing page is driven by Target. AEM will import Audiences from Target so that they can be used right within AEM to create activities to personalize our page. AEM then synchronizes the activity to Target.

DTM is a Digital Marketing cloud service that allows a marketer to manage Adobe and third-party tags used for tracking or other analytic purposes. It is done through client-side scripting that injects tag related code throughout the pages of the site.

By using these products together, you can build engaging solutions that let you deliver the best content to a given web site visitor. That is, you display content from AEM DAM that meets the interest of the visitor. This development article walks you through how to build a solution that uses AEM, Analytics, Target, and DTM. 

The following illustration provides an overview some of the Marketing Cloud solutions (AEM, DTM, Analytics, and Target) used in this article.

Top Features in Adobe Experience Manager 6.2: Sites

1. Find Anything Anywhere
   Adobe has introduced an updated Touch UI. This is actually a great enhancement, but once again Adobe is changing the user interface. It’s hard on authors to constantly need to learn a new way of doing things and navigating around, and it means additional training for people when they upgrade from one version to another. But let’s not get bogged down with negativity. The new update to AEM is called OmniSearch and this is a really decent way of getting around. No longer do I have to do multiple clicks to find my tags. I just type “tags” and then the page loads. It also comes with search suggestions that show you all the possible destinations within AEM and the ability to do filtered searches. Also, they removed the need to go to a “selection mode” to select multiple items (pages, assets, etc.) when you need to activate them or update their properties. That’s great.
2. Templates for Everyone
   This is the new Template Editor. Last year when they teased this I mentioned how reluctant I was about it. Put the template in the hands of the authors and not the developers, are you insane? I still feel that way, but not as strongly now. An author can still royally screw things up, if you give them the permissions to do so. And that is the key. You can tie down this functionality by only giving it to people who actually know what they are doing. I was able to chat a bit with Gabriel Walt during Summit and that was his big piece of advice. So, we can still be happy, authors can still feel empowered, and developers won’t have to do as much. I had a chance to play around with it a bit in one of the Summit lab sessions and it certainly shows some promise.

Learn Sightly with Read–Eval–Print Loop in AEM 6.x

A great live code editing environment for Sightly templates with optional server-side JavaScript logic, executed on an Adobe Experience Manager instance. This little tool is great for learning Sightly and for experimenting with it, because the resulting output is displayed as you type.

To get started you need minimum Adobe Experience Manager 6+, there are you two ways you can setup your environment and start experimenting:-

1. Install as a Package

• Download the built package: com.adobe.granite.sightly.repl-1.0.2.zip.
• On your running AEM instance, go to Package Manager, click on Upload Package, browse to the previously downloaded package, and hit OK.
• Install the package com.adobe.granite.sightly.repl-1.0.2.zip. Don’t mind the missing dependencies, simply click the Install button and confirm.

2. Maven Method

• Checked-out https://github.com/Adobe-Marketing-Cloud/aem-sightly-repl repository with Git clone.
• Build and install it with following command line instruction:
  mvn clean install content-package:install

Once any of the above steps are performed for installation, go to the following URL on AEM instance localhost:4502/content/repl.html

Sightly Read Eval Print Loop (REPL) will give you three options:-

1. Source :- Shows the generated HTML Structure of webpage
2. View :- Output of webpage can be seen here, this is the same which you will see in your browser
3. Java :- Complied sightly Java class

It’s a great environment for people who are willing to get hands on Sightly and want to gain some experience in it.

Versioning ClientLibs in AEM

The Versioned ClientLibs ACS AEM Commons feature uses a Sling rewriter to add an MD5 hash to the paths of your clientlibs, forcing them to recache after every modification. Typically Adobe Experience Manager will use the lastModified property to determine when to recache, however versioned-clientlibs is a more reliable approach.

To implement the versioned-clientlibs feature, simply copy the node from /libs/cq/config/rewriter/default to some path inside your application. In this example, we’ll choose /apps/acslibs/config/rewriter. For the most part this path is arbitrary, however the config node must be inside a four-level-deep path that ends in config/rewriter to work.Read More
