[DAM] Custom DAM management / Add 'Alt' into images

Issue:

We need, for each asset to be able to edit the ‘alt’ text. The ‘alt’ text must be used on the site each time an asset is displayed.
When displaying an asset, the mechanism is the following :
-       Get the Locale from the request
-       When getting the asset, get the associated Alt property corresponding to the locale.
-       Populate the alt attribute with this value.

Resolution:

To achieve this, we can customize the DAM Asset Editor.
The AssetEditor is the form used to input asset properties and metadata.
Below is a screenshot of a customized form with four “alt” input (for four different locales).

The DAM uses the following nodes to render Asset Editor forms:
-       /libs/dam/content/asseteditors/formitems
-       /libs/dam/content/asseteditors/images/formitems
-       /libs/dam/content/asseteditors/images/jpeg/formitems
-       /libs/dam/content/asseteditors/image/tiff/formitems
We must not modify these files as it is source files for CQ.
But we can copy the /libs/dam/content/asseteditors node (and it’s child nodes) to /apps/dam/content/asseteditors to customize the form.
In this case, several nodes were added with the following specs:
• Label : Alt (or Alt Fr, Fr,…)
• jcr:PrimaryType: cq:Widget
• name: ./dc:alt (or ./dc:altDe…)
• xtype: textfield
etc,etc…..
Below is a representation of the new asseteditors/formitems tree:
Once the form is persisted, the new metadata are stored under the following node :
        /content/dam/{imagepath}/jcr:content/metadata
where now, the metadata node contains the following properties:

This is used by all bundle-based Persistence Managers. The default size of BundleCache is 8 MB. If this is too small it can cause an excessive number of read-accesses to the underlying persistence layer. Set the bundleCacheSize to something larger than the default.

How to custom CQ Login Module

In order to manage the login process in our project, we will use a custom CQ Login Module. We will admit the root URL of CQ instance is: http://localhost:4502/ . This value may change depending of your environment. The %CQ_HOME% variable we will mention refers to the CQ install path. It admits you have defined %CQ_HOME% as an environment variable. 1.         Update the repository definitions The login module must be referenced in the repository definitions. You have to edit the next file: %CQ_HOME%/crx-quickstart/repository/repository.xml Do a copy of repository.xml to repository.xml.original In repostiory.xml, replace  security  part of repository.xml with following: <Security appName="com.day.crx">         <SecurityManager class="com.day.crx.core.CRXSecurityManager"> <WorkspaceAccessManager class="org.apache.jackrabbit.core.security.simple.SimpleWorkspaceAccessManager"/>  ...
