collective.vaporisation 1.2.3

Plone portlet for vaporisation tagcloud

Latest Version: 1.3.7

Introduction

The collective.vaporisation addons for Plone give to the user a tag cloud portlet.

A tag cloud (or weighted list in visual design) is a visual depiction of keywords used into your site. Tags are usually single words and are normally listed alphabetically, and the importance of a tag is shown with font size. Thus, it is possible to find a tag alphabetically and by popularity. The tags are hyperlinks that lead to a collection of contents that are associated with a keyword. This hyperlinks makes a Plone search that show the list of contents marked with the keyword selected.

—Definition of tag cloud from Wikipedia

Big tagcloud used in a collective.portletpage area

With some CSS rules you can customize colors

An advanced feature is the “join navigation” that allows user to make a search related and sequential. During the search the view of the portlet is different. One first part of it shows only the keywords into the contents that are result of the search. A second one show the selected tags allowing user to remove some of them from the search.

Usage

When you add this kind of portlet, named “Tagcloud portlet”, you’re in front of an edit form with many fields.

We see in detail what they do:

Name to display
The name of the tag cloud. For display purposes.
Number of different sizes
This number will determine the biggest size.
Number of keywords to display
This number indicate the max number of keywords shown. The value 0 (zero) show all the keywords.
Cloud reload timeout
Time in minutes after which the cloud should be reloaded. This time isn’t the only parameter that force the reload of cloud. Put this value to “0” for disabling caching (don’t do this on production).
Start path
Only the objects under this directory will be taken in consideration. If empty (default), the portlet will search in all the site.
Indexes to use
In this field you can select the indexes to use. We can use all the KeywordIndex defined into your site. The default one is “Subject” index of Plone.
Type of contents
We can filter the objects by type. Only the objects of the selected types will be used to search the keywords.
Activate joint navigation
With this options active the portlet change his view to show only the related keywords. This will be seen during the functionality of search of contents with some keywords.
Use only the keywords of this list
A whitelist for a manual choise of the keywords to show. Remove from keywords list: A blacklist for remove some keywords from the shown.
Mode to use
Select a mode of use among those diponibile. Now we have only one mode of use. Other one can be implementated by external package through an adapter.
Sort keywords
If actived, the keywords will be sorted alphabetically.

TODO and know issues

  • If you’re using more than one tag cloud portlet you have to remind to use different name. In this way, the “join navigation” will be applied only to the portlet where the user clicks over a keyword.

  • The list of keywords used into the edit form doesn’t change dinamically when the filters change To use the whitelist or the blacklist after a change to one of field used to filter the contents (like “Start path”, “Indexes to use” and “Type of contents”) you need to save the portlet and re-enter into edit.

    During the load of edit form the vocabularies will be recreated.
