Workspace Filter in AEM

Posted on by Prahlad Dutta

The filter is used to define what parts of the JCR repository will be inport or export during package installation or un-installation.

The filter.xml file is present under META-INF/vault. filter.xml has below structure. It consist a set of filter elements which is having a mandatory root attribute and optional include and exclude child elements.

<?xml version="1.0" encoding="UTF-8"?>
<workspaceFilter version="1.0">
    <filter root="/apps/techiearchive">
        <exclude pattern="/apps/techiearchive/install" />
    </filter>
    <filter root="/etc/clientlibs/techiearchive"/>
    <filter root="/etc/notification/email/html/techiearchive"/>
</workspaceFilter>

Filter elements

The filter elements are independent of each other and define include and exclude patters for subtrees. The root of a subtree is defined by the root attribute, which must be an absolute path.

The filter element can have an optional mode attribute which specified the import mode used when importing content. the following values are possible:

replace

This is the normal behavior. Existing content is replaced completely by the imported content, i.e. is overridden or deleted accordingly.

merge

Existing content is not modified, i.e. only new content is added and none is deleted or modified.

update

Existing content is updated, new content is added and none is deleted.

What is content fragments?

Content fragment has been introduced in AEM6.2. It allow us to create, design and page independent content. It’s store as an Asset so, it is managing through Asset console. It’s allow to use in multiple location or channels eg: mobile site, desktop site etc. Content Fragments do not contain any layout and design. Content fragments are not available in the classic UI.

Since AEM6.4 it can deliver in JSON format, using Sling Model export capabilities in AEM core components. AEM Content Fragments can be used to describe and manage structured content. Structured content is defined in models that can contain a variety of content types; including text, numerical data, boolean, date and time, and more. Learn more about content fragment.
