Tag-me Plugin

Plugin to tag wiki content collectively in order to find content by tags and to get a meaningful page ranking.

Introduction

Overview

The larger a wiki gets, the harder it is to find content. This wiki tagging plugin attempts to solve the issue based on these assumptions:

Assertion 1: Intranet search does not work well due to inadequate ranking of search engines on intranets. This is because there are typically not many cross-links between pages.
Assertion 2: Let the individuals build their own taxonomy to find content quickly
Assertion 3: Let the users do the ranking to get an "human intelligence" ranking of important content

There are clear benefits in tagging content in a large TWiki (10K or more topics):

Find relevant content in a large system quickly,
- by quickly accessing related topics via the tags on a topic
- by quickly accessing related topics via related tags listed in a specific tag view
- by quickly identifying important tags in the tag cloud
Access my favorite topics quickly (assuming I tag topics of interest)
Solve the search ranking issue of wiki content indexed by a search engine
Help solve stale content issue (old topics do not get tagged)

The design goals of the TagMePlugin were as follows:

Any topic can be tagged by individuals -> create taxonomy for individuals
Show tag statistics of all users on each topic -> show popularity
Encourage users to reuse the same tag on a topic -> get a "collective ranking", or "vote for a tag", or "tag count"
Make it as easy as possible to increase the tag count
Make it as easy as possible to add a new tag to a topic
Encourage users to create new tags, but try to avoid use of similar tags for the same subject
Search for topic by tag, sorted by tag popularity

Behavior on different site mode

A TWiki page can have a number of tags, but tagging only works on a master site. In another word, tagging is disabled when current site mode is readonly or salve. If you are not familiar with site modes, please refer TWiki:Codev/ReadOnlyAndMirrorWebs.

Multiple tag namespaces support

By default, TagMePlugin has only one tag namespace. You can set "$TWiki::cfg{TagMePlugin}{SplitSpace} = 1" to support multiple namespaces. With multiple namespaces, each top level web has its own tag namespace. Tag data files are stored at "pub/TOP_LEVEL_WEB/.tags/". When a page is copied or moved, its tag data is also copied or moved along with it.

When multiple name spaces are enabled, if UserSubwebs is in effect, each user subweb has its own tag name space.

Tag name space example

Each top level TWiki site has its own tag name space. Let's say Site1 has the following tags:

apple
orange
lemon

Another site Site2 can decide what tags it has on its own. e.g.

kiwi
durian
mango

This is what it means by each top level TWiki site has its own tag name space. Sub sites share the same tag names as its parent site. The site Site1/Sub1, which is a sub site of Site1 has the same exact tags as Site1:

apple
orange
lemon

Permission for user agnostic tags

TagMePlugin makes tags user-related. User can not remove a tag when it is tagged by someone else. A TWiki site can have user agnostic tags by setting "$TWiki::cfg{TagMePlugin}{UserAgnostic} = 1". The tag T put to the page P1 by the user U1 and the tag T put to the page P2 by U2 are equally the tag T for everybody. This allows user to remove a tag added by someone else.

Tag change permission and tagging permission

There are two sorts of permissions

permission to create/rename/delete tags (let's call it tag change permission here).
adding and removing tags to/from a page (let's call it tagging permission here).

A user having tagging permission to a page (2) but not having tag change permission (1) can add an existing tag to the page and can remove a tag. A user having tag change permission is guaranteed to have tagging permission to all the pages of the site. This may sound unnecessary. The logic behind this is as follows.

If you have tag change permission, you can add and delete tags. Only unused tags can be deleted. As such, when you delete a tag, you need to remove the tag from all pages having it.
If you have tag change permission, you can rename an existing tag. A rename operation ends up changing tags of multiple pages.

For these, if you have tag change permission but you don't have tagging permission, it's strange.

Tag change permission is a site-wide permission whereas tagging permission is either site-wide or page by page.

How tag change permission and tagging permission are determined

By default, users who can edit WebPreferences has tag change permission. Also by default, users who can edit a page can add and remove tags to/from the page.

You can explicitly specify tag change permission by setting ALLOW_TAG_CHANGE and/or DENY_TAG_CHANGE variables on WebPreferences. The way they work is similar to other access control variables ALLOW* and DENY*. You can find out the details of TWiki's access control at TWiki.TWikiAccessControl.

Tagging permission can be explicitly set by the DENYTOPICTAG, ALLOWTOPICTAG, DENYWEBTAG, and ALLOWWEBTAG variables.

Because of the way tag change permission and tagging permission behave, if you want to restrict who can tag pages by setting ALLOWWEBTAG, ALLOWTOPICTAG, DENYWEBTAG, and DENYTOPICTAG, while allowing people to edit pages, you need to restrict who can change tags by setting ALLOW_TAG_CHANGE and/or DENY_TAG_CHANGE.

Regardless of these settings, the members of the contact mail group of a site have tag change permission. Hence they can add and remove tags on any page of the site.

User Interface

Tag List on Topic

Every topic has a list showing all tags associated with the topic. Additional tags can be added to the topic, and new tags can be created.

Default "twiki" style

Screenshot of tags shown on a topic:

You see:

a list of tags with vote count and add/remove vote buttons,
an add tag selector
a link to create a new tag
a link to the all tags view

"blog" style

But the same control can have a different look and feel if we specify style="blog". In view mode it has a terse apperance:

Screenshot of tags on a topic, style=blog

But, if you click on Tags, and that you have an account and can edit tags, you will see:

Create, Rename, Delete tags

Create New Tags

Go to TWiki.TagMeCreateNewTag to create new tags.
Anyone is allowed to create new tags.

For developers:
Use the url parameter createtag=my+tag+name to pass a new tag name to the form.

Add Tag to Topic

Once a new tag is created, it can be added in the tag list of the topic.

Rename Tags

Go to TWiki.TagMeRenameTag to rename existing tags.
Rename permissions are controlled with ALLOW_TAG_CHANGE (see Plugin Settings below).

For developers:
Use the url parameters renametagfrom=my+old+tag+name and renametagto=my+new+tag+name to pass the old and new tag names to the form.

Delete Tags

Go to TWiki.TagMeDeleteTag to delete existing tags.
Delete permissions are controlled with ALLOW_TAG_CHANGE (see Plugin Settings below).

For developers:
Use the url parameter deletetag=my+tag+name to pass the to-be-deleted tag name to the form.

List All Tags

TWiki.TagMeViewAllTags shows all tags used in the system. The font size indicates the overall tag count of a tag.

Screenshot of tag cloud in the list all tags view:

Tip: In a WebHome of a web you can show a tag cloud of all tagged topics in that web with this variable:

<div class="tagmeTagCloud" style="line-height:2em;">
%TAGME{ tpaction="showalltags" format="<a href=\"%SCRIPTURL{view}%/%SYSTEMWEB%/TagMeSearch?tag=$tag\" style=\"font-size:$size%\">$tag</a>" separator="&nbsp; " minsize="94" maxsize="220"}%
</div>

List My Tags

TWiki.TagMeViewMyTags shows all tags used by logged-in user. The font size indicates the overall tag count of a tag.

Tag Search

TWiki.TagMeSearch shows a list of topics that are tagged with all of the selected tags, sorted by relevance. Topics with a high tag count are shown first.

Plugin Variable

The Plugin handles a %TAGME{}% variable that performs different actions. The tpaction="" is a required parameter.

%TAGME{ tpaction="show" ...}% - shows the tag list on topic

Parameter	Comment	Default
`style="blog"`	will expand into a "tag edit" frame that allows tag management as commonly found in blogs or tag systems like delicious, but only if tpaction is actually present. If `tpaction` is omitted, but the style is `"blog"`, will show nothing. Thus a button to make the edit tags frame appear can be put as: `<a href="%SCRIPTURL{viewauth}%/%SYSTEMWEB%/%TOPIC%?tpaction=show">Edit tags</a>`	"twiki"
`label=", "`	(for style=blog) link label (text) to open the edit tags form	`""`
`button=", "`	(for style=blog) the complete button, link or html construct that will be shown when not in edit tag mode. Should open the Edit tag form when clicked by redirection to this same topic with a `tpaction=show` added. Overrides `label`.	`""`
`header="..."`	(for style=blog) Printed before the edit tags form if it is not empty, `$n` can be used for newlines. e.g: `header="Manage your tags: <i>"`	`""`
`footer="..."`	(for style=blog) Printed after the edit tags form if it is not empty, `$n` can be used for newlines. e.g: `footer="</i>"`	`""`

%TAGME{ tpaction="showalltags" ... }% - view all tags or my tags as a tag cloud

Parameter	Comment	Default

`format="..."`	Format of a tag, tokens `$tag`, `$size`, `$marker` (adds selected="selected" for use in html options), `$count`, `$order`	`"$tag"`
`header="..."`	Printed before the list of tags if it is not empty, `$n` can be used for newlines. e.g: `header="Tags: <i>"`	`""`
`separator=", "`	Separator between tags	`", "`, unless `format` has been specified
`footer="..."`	Printed after the list of tags if it is not empty, `$n` can be used for newlines. e.g: `footer="</i>"`	`""`

%TAGME{ tpaction="query" ... }% - tag search

Parameter	Comment	Default
`by="me"`	My tagged topics only; can also be a USERNAME	all tagged topics
`web="%WEB%"`	Limit query to a web	current web
`topic="*Plugin"`	Limit query to a topic, or a comma-space delimited list of topics with optional asterisk wildcards	all topics

`format="..."`	Format of a topic, any token of TWiki.FormattedSearch can be used, such as `$web`, `$topic`, `$summary`, `$rev`, `$n`. In addition, `$votecount` expands to the number of tag votes, `$size` to the suggested font size, and `$taglist` to the tag list of the topic.	(nice formatting)
`separator=", "`	Separator between tags, `$n` or `$n()` can be used for newlines	`"$n"`
`limit=""`	limit number of results if `sort="web"`
`header=""`	if `sort="web"`, add this header once per web with results (only `$web` is interpreted)	`---+++ $web`
`footer=""`	if `sort="web"`, add this footer once per web with results (only `$web` and `$count` and $showmore are interpreted)	`showing $limit out of $count results $showmore`
`refine`	Normally related tags are shown that when clicked on will search for the related tag. If `refine` is set to 1, then the link instead will add the clicked tag to the set of tags being searched for, allowing you to incrementally refine search results. If not set the value of `ALWAYS_REFINE` is used.

Parameter	Comment	Default
`tag="..."`	Name of tag	(required)
`nostatus="on"`	Turn off status text shown when a tag is removed or voted on	(show status text)

How to put tags on every page

To show the tag interface at the top of the page directly below the breadcrumb (like on twiki.org), use the default template view.tagme.tmpl in the templates directory.

This template is in fact a 'skin' template. To enable it, write in Main.TWikiPreferences:

   * Set SKIN = tagme,pattern

The list of skins can be appended, for instance: tagme,corporate,pattern.

For the "blog" style, use for a simple "Tags: list-of-tags (edit)" at the top of the page:

   * Set SKIN = tagme_styleblog,pattern

And for an alternate style, with no tags line shown if no tags exists, and the button to open the tag edit frame placed at the right of the Edit and Attach ones, in the same style, on the upper right:

   * Set SKIN = tagme_styleblogbutton,pattern

For TWiki 4.1, use:

   * Set SKIN = tagme04x01,pattern

Customizing the appearance

If you customize your site you probably want to change overall appearance. You can find instructions how to do that - at least for default pattern skin - in TWiki.PatternSkinCssCookbook.
The short summary is:

Create an empty CSS file, for instance sitestyle.css
Copy the CSS styles for tagmetags (see below at Example styles used on twiki.org) into the file
Attach the file to Main.TWikiPreferences

In Main.TWikiPreferences, write:

   * Set USERSTYLEURL = %PUBURL%/%USERSWEB%/TWikiPreferences/sitestyle.css

Other places for the tag interface

To show the tags in the top bar, edit TWiki.WebTopBar and copy:

<div class="tagmetags">
Tags: %TAGME{ tpaction="%URLPARAM{tpaction}%" web="%WEB%" tag="%URLPARAM{tag}%" }%, [[%SYSTEMWEB%.TagMeViewAllTags][view all tags]]
</div>

To show the tags at the bottom of every page, write in Main.TWikiPreferences:

 * Set WEBCOPYRIGHT = Tags: %TAGME{ tpaction="%URLPARAM{tpaction}%" web="%WEB%" tag="%URLPARAM{tag}%" }%, [[%SYSTEMWEB%.TagMeViewAllTags][view all tags]] %BR% Copyright &copy; 1999-%GMTIME{"$year"}% by... etc

Show tags without vote buttons

To just show the tags for a topic, without buttons or "Create new tag" link, use a showalltags search:

Tags: %TAGME{ tpaction="showalltags" web="%WEB%" topic="%TOPIC%" format="<a href=\"%SCRIPTURL{view}%/%SYSTEMWEB%/TagMeSearch?tag=$tag\">$tag</a> " }%

Tag styles

CSS Styles

TagMePlugin writes the following CSS styles:

Class Used where

tagMeControl Around 'tags shown on a topic': tag link plus vote counter plus add/vote button

tagMeVoteCount Around vote count number

tagMeNotification span: One-line notification feedback after adding or removal of a tag and on in this process

tagMeNotification div: Block of notification feedback after creation of a tag and on errors in this process

tagmeAction Link style for buttons add and remove tag vote

tagmeNavigation Table style for tabbed admin pages

Class	Used where
`tagMeControl`	Around 'tags shown on a topic': tag link plus vote counter plus add/vote button
`tagMeVoteCount`	Around vote count number
`tagMeNotification`	`span`: One-line notification feedback after adding or removal of a tag and on in this process
`tagMeNotification`	`div`: Block of notification feedback after creation of a tag and on errors in this process
`tagmeAction`	Link style for buttons add and remove tag vote
`tagmeNavigation`	Table style for tabbed admin pages

Search results CSS Styles

Class Used where

tagmeRelated Text style of the line "Related tags (Click to refine the search)"

tagmeResultsTable Table style for search results

tagmeResultsTableHeader Table header with link to topic, last modified date and author. These have the additional classes td.tagmeTopicTd, td.tagmeDateTd, td.tagmeAuthorTd, tagmeTopicTdWeb

tagmeResultsDetails Wrapper around tagmeResultsSummary and tagmeResultsDetails

tagmeResultsSummary The topic summary

tagmeResultsTags List of tags for the topic

Class	Used where
`tagmeRelated`	Text style of the line "Related tags (Click to refine the search)"
`tagmeResultsTable`	Table style for search results
`tagmeResultsTableHeader`	Table header with link to topic, last modified date and author. These have the additional classes `td.tagmeTopicTd`, `td.tagmeDateTd`, `td.tagmeAuthorTd`, `tagmeTopicTdWeb`
`tagmeResultsDetails`	Wrapper around `tagmeResultsSummary` and `tagmeResultsDetails`
`tagmeResultsSummary`	The topic summary
`tagmeResultsTags`	List of tags for the topic

Preventing link wrap

If users are allowed to use spaces in their tag names (when NORMALIZE_TAG_INPUT is set to 0), tag links may break halfway to the next line. To prevent wrapping, add a wrapper div around the tags:

<div class="tagmeTagCloud">
%TAGME{ ... }%
</div>

This CSS style is included in tagme.css:

.tagmeTagCloud a {
   white-space:nowrap;
}

Example styles used on twiki.org

To show the 'tags shown on a topic':

<div class="tagmetags">
Tags: %TAGME{ tpaction="%URLPARAM{tpaction}%" web="%WEB%" tag="%URLPARAM{tag}%" }%, [[%SYSTEMWEB%.TagMeViewAllTags][view all tags]]
</div>

CSS styles:

.tagmetags select {
   font-size:.8em;
   margin:0 .25em;
}
.tagmetags a {
   text-decoration:none;
   white-space:nowrap;
}
.tagmetags a:link,
.tagmetags a:visited {
   color:#8E9195; /* all links are gray; for blue links use: #06c */
   text-decoration:none;
}
.tagmetags a:hover {
   color:#FBF7E8; 
}
.tagMeControl {
   color:#8E9195; /* gray for non-links */
}

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, e.g., %TAGMEPLUGIN_SHORTDESCRIPTION%.

NOTE: Do not change the settings here, overload them in the Main.TWikiPreferences. Prefix a setting with TAGMEPLUGIN_, e.g. to overload NORMALIZE_TAG_INPUT define a TAGMEPLUGIN_NORMALIZE_TAG_INPUT setting in the Main.TWikiPreferences.

One line description, is shown in the TextFormattingRules topic:
- Set SHORTDESCRIPTION = Tag wiki content collectively to find content by keywords

Log add/create actions:
- Set LOGACTION = 1

Optionally normalize tag names. Set to 1 to translate international characters to their latin match (ü to ue, å to aa, etcetera), and to convert spaces to underscores.
Set to 0 to allow any user input, except for the reserved characters ,#'"|*.
Setting to 0 also sorts tags case insensitive: 'U' comes after 't'.
- Set NORMALIZE_TAG_INPUT = 0

If 1, then the refine parameter is always added to TAGME queries.
- Set ALWAYS_REFINE = 1

List of users and groups that are allowed to change (rename and delete) tags (names separated by commas).
Users that are not allowed to change post their change requests to TagMeChangeRequests.
If not set anyone can change tags.
- Set ALLOW_TAG_CHANGE = TWikiAdminGroup

Bundles are groups of tags that are presented as menus for convenience. It is a list of space-separated (or comma-separated if your tags may contain spaces) prefixed by bundle labels terminated by colon (":"). e.g:
- Set BUNDLES =
- #Set BUNDLES = Rating: * * * Todo: to_blog to_read
- #Set BUNDLES = Rating:, , *, **, Todo:, to_blog, to_read

Debug plugin: (See output in data/debug.txt)
- Set DEBUG = 0
