Define new tag namespace & tags:Create new tag namespace(page-type) through http://localhost:4502/tagging
Create required tags under page-type namespace
Override the the head.jsp if the page component is inhering from foundation/components/page. Add required logic in head.jsp to include the custom metatags from AEM tags.
e.g.
<%
%><%@ include file="/libs/foundation/global.jsp"%><%
%><%@ page contentType="text/html; charset=utf-8" import="com.albinsblog.samples.core.TagsUtil,com.day.cq.tagging.*"%><%
TagManager tagManager = resourceResolver.adaptTo(TagManager.class);
String[] pageTypeTags = properties.get("./page-type", String[].class);
String pageTypes = TagsUtil.getTagTitles(tagManager, pageTypeTags);
%><head>
<cq:include script="/libs/wcm/core/components/init/init.jsp"/>
<meta name="page-types" content="<%= pageTypes %>" />
</head>
TagsUtil.java - util class to fetch the tag titles and convert the titles to required formats.
import com.day.cq.tagging.Tag;
import com.day.cq.tagging.TagManager;
public class TagsUtil {
public static String getTagTitles(TagManager tagManager, String[] typeTags) {
StringBuffer typeBuffer = new StringBuffer();
if (typeTags != null) {
for (String typeTagId : typeTags) {
Tag typeTag = tagManager.resolve(typeTagId);
if (typeTag != null) {
String tagPath = typeTag.getTitlePath();
String[] splitTags = tagPath.split(":");
String tagName = splitTags[1];
if (typeTag != null)
typeBuffer.append(tagName + ";"); }
}
if (typeBuffer.length() != 0)
typeBuffer.deleteCharAt(typeBuffer.length() - 1);
}
return typeBuffer.toString();
}
}
Configure required tags in the page properties dialog
The defined meta tag will be added to the page
