Reading meta tag values of an asset

Hi Kirithi,

Thanks for confirmation of code, 

I feel couple of reason for not working of code as getMetadataValue(String name) return string but if you see Dam jcr screenshot their property is stored as String[].

This is one helpful link I found : http://dev.day.com/docs/en/cq/current/dam/customizing_and_extendingcq5dam.html

Please see screenshots

Attached missing screenshots

Hi Opkar and Dubey,

                               Thanks:-) ,It is Working now. In order to learn I just want to know why it is not working in my approach.

Kirithi

Hi Kirithi,

here is some code I wrote in Fiddler (part of ACS commons) to extract the tags for an asset.

Regards,

Opkar

<%@include file="/libs/foundation/global.jsp"%><%
%><%@page session="false" contentType="text/html; charset=utf-8" 
    pageEncoding="UTF-8"
    import="org.apache.sling.api.resource.*,
    org.apache.sling.jcr.resource.*,
    com.day.cq.dam.api.*,
    java.util.*,
    javax.jcr.*,
    com.day.cq.search.*,
    com.day.cq.wcm.api.*,
    com.day.cq.dam.api.*,
    com.day.cq.dam.api.metadata.*"%><%

    // Code here
    String resourcePath = "/content/dam/geometrixx/portraits/scott_reynolds.jpg";
    Resource res = resourceResolver.getResource(resourcePath);
    Asset asset = res.adaptTo(Asset.class);

    Map<String, Object> assetMap = asset.getMetadata();
    Object[] obj = (Object[])asset.getMetadata("cq:tags");
    
    for(int x=0;x<obj.length;x++){
    %>
    <br>
    <%
        out.println(obj[x]);
    }
%>

No Worries, Please use below code to get things done. Its workings in my AEM.

<%@include file="/libs/foundation/global.jsp"%> <jsp:directive.page import="com.day.cq.dam.api.Asset, com.day.cq.tagging.TagManager,com.day.cq.tagging.Tag " /> <% try { Resource r = resourceResolver.getResource("/content/dam/geometrixx/drm/with-drm.jpg"); Asset asset = r.adaptTo(Asset.class); String title; Object[] titleArray = null; Object titleObj = asset.getMetadata("cq:tags"); if (titleObj instanceof Object[]) { titleArray = (Object[]) titleObj; } for(Object ob:titleArray) { String a = ob.toString() ; TagManager tagManager=null; tagManager = resourceResolver.adaptTo(TagManager.class); Tag custTag = tagManager.resolve(a); out.print(custTag.getTitle()); } } catch(Exception e) { } %>

For testing purpose I wrote this in JSP its recommended to write this in Java class.

Let me know how it goes 

Hi,

    I followed the above approach but length of tag is not coming properly.

    It is returning zero.

    So I directly accessed through its property

String tagStr = aseetStr.getMetadataValue("cq:tags");

   Thanks!

Kirithi

Hi,

    Please find below the code snippet

String tagStr = aseetStr.getMetadataValue("cq:tags"); tagArray = tagStr.split(","); for(String t1:tagArray) { LOGGER.info("<<<<<tagArray length>>>>>>"+t1); tagManager = resolver.adaptTo(TagManager.class); Tag custTag = tagManager.resolve(t1); LOGGER.info("Tag Title---->>>>"+custTag.getTitle()); }

   Able to access tag values up to one level irrespective of number of tags have been added.

Thanks!

Kirithi

Hi,

Can you please share the code block to get things more clear. May then I could help you better.

Hi,

The reason might be tags aren't available in current instance. 
Tag custTag = tagManager.resolve(t1);
The TagManager will return null value when the tag is not available.
Steps to fix this:
1. Check whether the tags which are stored in the asset properties are available in tagging console or not . (current instance)
2. If they are not available,please activate the tags from author instance. 

This mighe be the solution.
