How to implement metadata keyword tags

Question

Can someone please advise me on how to implement meta keyword tag <meta name="keyword" content="..."> for individual community page? We have a set of keywords for each community page. I know we can just add the line above to base page layout if they are common keywords to all the community page but not sure whats the best way to add unique set of meta keyword tags to individual community page? FYI - We are using UCM for managing content for our site.

Answer 1

I always did this using a property on the page object.
1. Create a new property called "meta-keywords" and associate it to the community pages object through the global object property mapper utility.
2. Edit your community page and add any keywords you desire.
3. Write a custom tag for said property that takes a uuid as input (this way you can migrate and the tag remains the same.
4. same idea works for any meta tag.
Note: you are limited to 255 characters this way.
Or you can probably code some kind of tag that reads from UCM as well, but i always did it the above way.
Here is a tag example:
public class MetaPropertyCurrentPage extends ATag {
     private OpenLogger log = OpenLogService.GetLogger(
               OpenLogService.GetComponent(PTDebugHelpers.COMPONENT_PORTAL_COMMON),
               "customizations.tag.standard.MetaPropertyCurrentPage");
     public static final RequiredTagAttribute UUID;
     public static final ITagMetaData TAG;
     static {
          TAG = new TagMetaData("currpageproperty",
                    "Displays the value of the property in the current page from the uuid.");
     UUID = new RequiredTagAttribute("uuid", "The UUID for the property you want to open.",
AttributeType.STRING);
     @Override
     public ATag Create() {
          return new MetaPropertyCurrentPage();
     @Override
     public HTMLElement DisplayTag() {
          log.Info("Entering meta lookup");
          String objectid;
          String classid;
          HTMLElement result = new HTMLElementCollection();
          IEnvironment env = GetEnvironment();
          AActivitySpace owner = TaskAPIUICommon.GetEnvTypeObject(env);
          //get pageid
          int pageid = TaskAPIUICommunity.GetCurrentCommunityPageID(owner);
          //check if not a community page
          if (!TaskAPIUICommunity.IsCurrentPageCommunityPage(owner))
               return result;
          //convert to objectid
          try
               Object[] objectAndClassId = ((IPTMigrationManager)(((IPTSession)GetEnvironment()
               .GetUserSession()).OpenGlobalObject(PT_GLOBALOBJECTS.PT_GLOBAL_MIGRATION_MANAGER,
               false))).UUIDToObjectID(GetTagAttributeAsString(UUID));
               objectid = objectAndClassId[PT_MIGRATION_OBJECT_COLS.PT_MOC_OBJECTID].toString();
               log.Info( "found objectid" + objectid);
               classid = objectAndClassId[PT_MIGRATION_OBJECT_COLS.PT_MOC_CLASSID].toString();
               //check to make sure its a property
               if (Integer.parseInt(classid) != PT_CLASSIDS.PT_PROPERTY_ID)
                    return new HTMLComment("UUID does not belong to a property");
          catch (Exception e)
               log.Error(e, "error getting the objectid from the UUID.");
               return null;
          //now get the property from it
          IPTSession session = (IPTSession)GetEnvironment().GetUserSession();
          IPTObjectManager objMgr = session.GetPages();
          IPTPage page = (IPTPage)objMgr.Open(pageid, false);
          log.Info("Page name: " + page.GetName());
          IPTQueryResult qresult = page.GetObjectProperties().GetSinglePropertyData(Integer.parseInt(objectid), PT_PROPIDS.PT_PROPID_PROP_VALUE);
          if (qresult.Data() != null)
               IPTObjectManager objMgr2 = session.GetProperties();
               IPTProperty prop = (IPTProperty)objMgr2.Open(Integer.parseInt(objectid), false);
               String propName = prop.GetName();
               log.Info("Property name is: " + propName);
               String value = (String) qresult.Data()[1][0];
               if (lang.equalsIgnoreCase(propLocale) && value != null && !value.equalsIgnoreCase(""))
                    result.AddInnerHTMLString("<meta name=\"" + propName + "\" content=\"" + value + "\" />");
          else
               log.Info("Property Value not found.");
          return result;
     }
