Kostas Stamatis commented on DS-1227:
-------------------------------------
Dear all,
I just committed the changes to github according to your comments. I mention
below some notes:
Tim's comment #5: gr.ekt packages removed from these files
Tim's comment #1: After communicating with Marco Cavallo, the author of
opencloud library, he uploaded the artifacts in Maven Central (related sonatype
JIRA ticket: https://issues.sonatype.org/browse/OSSRH-4272), so I updated the
pom dependency respectively
Andrea's comment #4: I removed the unnecessary dependencies from pom.xml file
along with tomcat.jsp and servlet 3.0alpha that you mention
For all other comments that have to do with the UIUtil.java file and the SQL
queries in database, I just reused the BrowseDAO work that has been done for
the DS-1223 contribution (https://jira.duraspace.org/browse/DS-1227) with some
additions to support the tag cloud parameters. These parameters define the
execution time of the final SQL statements that BrowseDAO produces. The first
parameter is the maximun number of tags that need to be fetched (works like the
results per page parameter) and the cutting level which is the frequency level
that determines if a browse index should be fetched or not.
Those changes had as a result the removal of the code within the UIUtil.java
file (so all comments are resolved, magically) and the tag-cloud tag gets as
input parameter, not the index, but the BrowseInfo object that holds the
results of browsing. The latter means that tag cloud can be now easily
integrated in single.jsp file for browse indices of metadata type, scoped and
no scoped browses.
Finally, since in this contribution, same code was used (for BrowseDAO
classes), in case of merging, DS-1223 must be merged first and then this one.
Thanks a lot for your comments that lead to a more optimized version of this
contribution.

> Tag cloud for any browse index in the home page of DSpace
> ---------------------------------------------------------
>
> Key: DS-1227
> URL: https://jira.duraspace.org/browse/DS-1227
> Project: DSpace
> Issue Type: New Feature
> Components: JSPUI
> Reporter: Kostas Stamatis
> Assignee: Sands Fish
> Labels: has-patch, has-pull-request, tag-cloud
> Attachments: opencloud.jar, README.txt, tagcloud-patch.diff
>
>
> This proposed extension (implemented by National Documentation Centre/EKT -
> http://www.ekt.gr) allows the import of a tag cloud in the homepage of DSpace.
> The tag cloud can include values from any of the browse indices (of metadata
> type) of the repository and this is a configuration option along with many
> other options that you can see later.
> Tha tag cloud is implemented as a tag, meaning that it can be included in any
> page of the DSpace repository besides the homepage.
> USEFULNESS
> ---------------------
> Select a important browse index of your repository (i.e. subject) and include
> all major subjects of your records in the home page of DSpace to attract
> visitors.
> CONFIGURATION FILES
> ---------------------------------------
> Tag cloud is fully configurable within the default dspace.cfg configuration
> file of DSpace. The new configuration options are:
> #######################################################
> # TAG CLOUD configuration #
> #######################################################
> #
> # Should display tag cloud in the home page?
> # Possible values: true | false
> webui.tagcloud.home.show = true
> #
> # Select the browse index to create a tag cloud for in the home page
> # Possible values: any of the browse indices declared earlier in this conf
> file
> webui.tagcloud.home.bindex = subject
> #
> # Select the total tags to show
> # Possible values: any integer from 1 to infinity
> webui.tagcloud.home.maxtags = 50
> #
> # Should display the score next to each tag?
> # Possible values: true | false
> webui.tagcloud.home.showscore = false
> #
> # The score that tags with lower than that will not appear in the rag cloud
> # Possible values: any integer from 1 to infinity
> webui.tagcloud.home.cutlevel = 5
> #
> # Should display the tag as center aligned in the page or left aligned?
> # Possible values: true | false
> webui.tagcloud.home.showcenter = true
> #
> # The font size (in em) for the tag with the lowest score
> # Possible values: any decimal
> webui.tagcloud.home.fontfrom = 1.3
> #
> # The font size (in em) for the tag with the highest score
> # Possible values: any decimal
> webui.tagcloud.home.fontto = 2.8
> #
> # The case of the tags
> # Possible values: Case.LOWER | Case.UPPER | Case.CAPITALIZATION |
> Case.PRESERVE_CASE | Case.CASE_SENSITIVE
> webui.tagcloud.home.tagcase = Case.PRESERVE_CASE
> #
> # If the 3 colors of the tag cloud should be independent of score
> (random=yes) or based on the score
> # Possible values: true | false
> webui.tagcloud.home.randomcolors = true
> #
> # The ordering of the tags (based either on the name or the score of the tag)
> # Possible values: Tag.NameComparatorAsc | Tag.NameComparatorDesc |
> Tag.ScoreComparatorAsc | Tag.ScoreComparatorDesc
> webui.tagcloud.home.tagorder = Tag.NameComparatorAsc
> #
> # The first color of the tags
> # Possible values: hex value of the color (i.e. e3d67a)
> webui.tagcloud.home.tagcolor1 = D96C27
> #
> # The second color of the tags
> # Possible values: hex value of the color (i.e. e3d67a)
> webui.tagcloud.home.tagcolor2 = 424242
> #
> # The third color of the tags
> # Possible values: hex value of the color (i.e. e3d67a)
> webui.tagcloud.home.tagcolor3 = 818183
> EXTERNAL LIBRARIES
> --------------------------------------
> This extension makes use of the following external java library:
> a) opencloud |(http://opencloud.mcavallo.org/): a java library for for
> generating and managing tag clouds (under MIT licence)
> EXAMPLES
> -------------------
> Repository: Managing Authority of the Operational Programme "Education and
> Lifelong Learning"
