%TOC{title="Page contents"}%
Plugin to tag wiki content collectively or authoritatively in order to make it easier to find content and to get a meaningful page ranking. ---++ Introduction The larger a TWiki installation gets, the harder it becomes to find content. Even in a single web, if it has many topics, it may be difficult to keep the webcontent well organized and easy to navigate. Meanwhile, 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. Given the challenge, this plugin provides a tagging capability to TWiki. 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 * Solve the search ranking issue of wiki content indexed by a search engine * Help solve stale content issue (old topics do not get tagged) ---+++ Single v.s. multiple tag namespaces By default, there is only one tag namespace - all webs share a single tag set. If =$TWiki::cfg{TagMePlugin}{SplitSpace}= is set to 1, each top level web has its own tag namespace, which is shared by its subwebs. This is %IF{"{TagMePlugin}{SplitSpace}" else="*not*"}% the case on this TWiki installation. Switching between single tag namespace and multiple namespaces takes some effort, you should understand the consequences and set the appropriate value for your installation. %IF{"istopic 'UserSubwebs'" then="" else="
"}% If UserSubwebs are in effect (this is %IF{"{UserSubwebs}{Enabled}" else="not"}% the case on this installation), each user subweb has its own tag name space, which is shared by its subwebs, provided that multiple tag namespaces are in effect. %IF{"istopic 'UserSubwebs'" then="" else="
"}% ---+++ User conscious v.s. user agnostic tagging There are two modes of tagging - user conscious tagging and user agnostic tagging. Under user conscious tagging: * Let the individuals build their own taxonomy to find content quickly * Let the users do the ranking to get an "human intelligence" ranking of important content * Access my favorite topics quickly (assuming I tag topics of interest) It is used 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 Under user agnostic tagging: * A tag is put on a topic or not and there is not voting aspect in tagging. This implies that tags are user agnostic * You can restrict who can tag topics and probably you do You may not like the "democratic" nature of user conscious tagging. As the owner of a web, you may want total control over what tags topics in the web have. That is achieved by user agnostic tagging if you restrict tagging. By default, the plugin works in the user conscious tagging mode. If you set =$TWiki::cfg{TagMePlugin}{UserAgnostic}= 1, user agnostic tagging is used. If there is only one tag namespace (the default setting), user conscious or user agnostic is a global setting. You cannot set one web user conscious tagging while another web user agnostic. This is because under single tag namespace, tag search is global - all webs are subject to tag search. User conscious tagging and user agnostic tagging are semantically different. Different things should not be mixed together. If multiple tag namespaces are there, each top level web can choose user conscious or user agnostic tagging by setting =TAGMEPLUGIN_USER_AGNOSTIC_TAGGING= preferences variable =on= or =off= on the !WebPreferences topic. The default tagging mode is specified by =$TWiki::cfg{TagMePlugin}{UserAgnostic}=. Please note that setting =TAGMEPLUGIN_USER_AGNOSTIC_TAGGING= on the %LOCALTWIKIPREFS% topic doesn't have the effect. ---++ Permission ---+++ Who can add/delete/rename tags in the tag set The plug-in maintains a set of tags. Only tags in the tag set can be added to a topic. By default, any authenticated user can add/delete/rename tags in the tag set. But you may want to restrict who can modify the tag set. =DENY_TAG_CHANGE= and =ALLOW_TAG_CHANGE=, which are supposed to be set and finalized in %LOCALTWIKIPREFS%, restrict users who can modify the tag set. The way they work is similar to other access control variables DENY* and ALLOW*. You can find out the details of TWiki's access control at [[TWiki.TWikiAccessControl]]. Under multiple tag namespaces, =DENY_TAG_CHANGE= and =ALLOW_TAG_CHANGE= need to be set at the web level. Those variables set at the TWiki installation level don't take effect. Just like Main.TWikiAdminGroup members can view/update/delete any topic regardless of access restriction, they can add/delete/rename tags regardless of =DENY_TAG_CHANGE= and =ALLOW_TAG_CHANGE=. ---+++ Who can tag You may want to restrict who can put/remove tags to/from topics. Please note that whether you can add/delete/rename tags in the tag set (tag change permission) and whether you can put/remove tags to/from a topic (tagging permmision) are two different things. Tagging permission is set by the following preference variables. * DENYWEBTAG * ALLOWWEBTAG * DENYWEBTAG * ALLOWWEBTAG If none of above is set, a user who can change a topic can put/remove tags to/from the topic. Even if a user is denied tagging by the logic above, if the user has tag change permission, the user is allowed to put/remove tags to/from a topic. This may sound odd. The reason 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 topics having it. * If you have tag change permission, you can rename an existing tag. A rename operation ends up changing tags on multiple topics. For these, if you can change the tag set but you cannot put/remove tags, it's strange. As you can imagine, Main.TWikiAdminGroup members can tag any topic regardless of access restriction. %IF{"istopic 'ReadOnlyAndMirrorWebs'" then="" else="
"}% ---+++ Behavior on a read-only web If ReadOnlyAndMirrorWebs is in use, some webs are read-only. This plug-in supports read-only webs. On a read-only web, tags are displayed but cannot be manipulated. %IF{"istopic 'ReadOnlyAndMirrorWebs'" then="" else="
"}% ---++ 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:
Screenshot of tags 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:
Screenshot of tags on a topic, style=blog
In this style, you can define tag bundles - 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 TAGMEPLUGIN_BUNDLES = * #Set TAGMEPLUGIN_BUNDLES = Rating: * ** ** Todo: to_blog to_read * #Set TAGMEPLUGIN_BUNDLES = Rating:, *, **, **, Todo:, to_blog, to_read Tags in bundes need to be valid - simply putting a tag in a bundle doesn't make it valid. You need to create it on TagMeCreateNewTag before putting a tag in a bundle. =TAGMEPLUGIN_BUNDLES= is a preferences variable and you can set its value at the installation level, the web level, or the topic level. ---+++ Create, rename, delete, list, search tags There are topics for various tag operations as shown below. Links to those topics are provided from various places off the shelf. Things are supposed to just work without doing anything special. So this part of this topic is to inform you what topics are there for tag manipulation rather than how to set things up. | *Operation* | *Topic name* | | Creation | TagMeCreateNewTag | | Rename | TagMeRenameTag | | Deletion | TagMeDeleteTag | | Listing | TagMeViewAllTags, TagMeViewMyTags | | Search | TagMeSearch | The %SYSTEMWEB% web has all of those topics. And the =_default= template web has all of those topics now, but not in the past. Lack of those topics in each web is not an issue under single tag namespace since only those topics in the %SYSTEMWEB% web are referred to. All tag operations are done on those topics in the %SYSTEMWEB% web. If you employ multiple tag namespaces, each top level web needs those topics to manipulate tags in the web, hence you may need to copy those topics from the =_default= web. ---++++ Create, rename, delete tags programmatically You may want to do tag creation, rename, deletion programatically. Maybe needless to say, you can do that by mimicking form submission from those pages. | *Topic name* | *Form parameter* | | TagMeCreateNewTag | =createtag=my+tag+name= | | TagMeRenameTag | =renametagfrom=my+old+tag+name=
and =renametagto=my+new+tag+name= | | TagMeDeleteTag | =deletetag=my+tag+name= | ---++++ List tags TagMeViewAllTags shows all tags either in the TWiki installation (if there is only one tag namespace) or in the current top level web (if each top level web has its tag namespace). The font size indicates the overall tag count of a tag. Screenshot of tag cloud in the list all tags view:
Screenshot of view all tags tag cloud
__%T% Tip:__ In a %HOMETOPIC% of a web you can show a tag cloud of all tagged topics in that web with this variable:
%TAGME{ tpaction="showalltags" format="$tag" separator="  " minsize="94" maxsize="220"}%
If user conscious tagging is in effect, TagMeViewMyTags shows all tags used by the logged-in user. The font size indicates the overall tag count of a tag. Under user agnostic tagging, TagMeViewMyTags shows the same result as TagMeViewAllTags. ---++++ Tag search 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 variables ---+++ TAGME Various tag operations are provided through the =%TAGME{}%= variable. The =tpaction=""= parameter is required. * =%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.

It's expanded to =on= if the current web employs user agnostic tagging. This variable is for reading, not for setting whereas =TAGMEPLUGIN_USER_AGNOSTIC_TAGGING= (with =_TAGGING=) is for setting. ---+++ TAGMEPLUGIN_USER_AGNOSTIC_TAGGING =%TAGMEPLUGIN_USER_AGNOSTIC_TAGGING%= is referred to by the plugin code only if multiple tag namespaces are there. This is to override the installation-wide default of user conscious tagging or user agnostic tagging. The installation-wide default is specified by =$TWiki::cfg{TagMePlugin}{UserAgnostic}=. #TagsOnPage ---++ 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 [[%LOCALTWIKIPREFS%]]: 
   * 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 [[%SYSTEMWEB%.PatternSkinCssCookbook]]. %BR% The short summary is: * Create an empty CSS file, for instance =sitestyle.css= * Copy the CSS styles for =tagmetags= (see below at [[%TOPIC%#ExampleStyle][Example styles used on twiki.org]]) into the file * Attach the file to [[%LOCALTWIKIPREFS%]] * In [[%LOCALTWIKIPREFS%]], write: * Set USERSTYLEURL = %PUBURL%/%USERSWEB%/TWikiPreferences/sitestyle.css ---+++ Other places for the tag interface To show the tags in the top bar, edit [[%SYSTEMWEB%.WebTopBar]] and copy:
Tags: %TAGME{ tpaction="%URLPARAM{tpaction}%" web="%WEB%" tag="%URLPARAM{tag}%" }%, [[%SYSTEMWEB%.TagMeViewAllTags][view all tags]]
To show the tags at the bottom of every page, write in [[%LOCALTWIKIPREFS%]] assuming the skin's view template has =%WEBCOPYRIGHT%= at the bottom: * Set WEBCOPYRIGHT = Tags: %TAGME{ tpaction="%URLPARAM{tpaction}%" web="%WEB%" tag="%URLPARAM{tag}%" }%, [[%SYSTEMWEB%.TagMeViewAllTags][view all tags]] %BR% Copyright © 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="$tag " }% ---++ 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 | ---++++ 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.

To prevent wrapping, add a wrapper =div= around the tags:

Otherwise, user conscious tagging. * =$TWiki::cfg{TagMePlugin}{NormalizeTagInput}= (default 0) %BR% When you add a new tag, the tag name is somewhat normalized. If this parameter is 1, then the degree of normalization is higher - a tag consists only of non-accented letters, numbers, or underscores. To achieve that, spaces and hyphens are replaced with underscores, characters other than non-accented letters, numbers, or underscores are eliminated, all uppercase letters are made lowercase. If this parameter is 0, then the following characters are eliminated: ^#,'"|* %BR% Other than that, no normalization is conducted. * =$TWiki::cfg{TagMePlugin}{LogAction}= (default: 0) %BR% If 1, then tag actions such as creation of a new tag, adding a tag to a topic are logged in the log file in the same manner as topic view and edit are logged. * =$TWiki::cfg{TagMePlugin}{AlwaysRefine}= (default: 0) %BR% If 1, then the =refine= parameter is always added to TAGME queries. * =$TWiki::cfg{TagMePlugin}{TagLenLimit}= (default: 30) %BR% Maximum length of a tag name * =$TWiki::cfg{TagMePlugin}{Debug}= (default: 0) %BR% If 1, then debug messages are put into the debug log file ---+++ Switching !SplitNamespace and/or !UserAgnostic You may change ={TagMePlugin}{SplitSpace}= or ={TagMePlugin}{UserAgnostic}= after using %TOPIC% for a while. This is not recommended, but you may need to do that. So here's how you can deal with it. ---++++ Switching !SplitNamespace If ={TagMePlugin}{SplitSpace}= is 0, all tag data, namely the tag set and which topic has which tags put by whom, is stored in the following directory:%BR% =$TWiki::cfg{WorkingDir}/work_areas/TagMePlugin= If the directory there are two kinds of files: * =_tags_all.txt= - having the tag set * _tags_WEB.TOPIC.txt (e.g. =_tags_TWiki.WebPreferences.txt=) - having who put which tag to which topic If ={TagMePlugin}{SplitSpace}= is 1, tag data is stored in the =pub= directories of top level webs under the =.tags= subdirectory. For example, !WebA's tag data is stored in =pub/WebA/.tags=, !WebB's tag data is stored in =pub/WebB/.tags=, etc. Tag data file names and content are the same as they are under single tag namespace configuration. As you see, under the multiple tag namespace configuration, tag data is not stored under =$TWiki::cfg{WorkingDir}=. Instead, it's stored under pub/WEB_NAME. This is to mirror a web simply by mirroring data/WEB_NAME and pub/WEB_NAME. If you change ={TagMePlugin}{SplitSpace}= from 0 to 1, all webs become unable to see existing tag data since they refer to their own tag data, which is empty immediately after the switch. There is no ready-made tool, but it's easy to move/copy tag data files from =$TWiki::cfg{WorkingDir}/work_areas/TagMePlugin= to pub/WEB_NAME/.tags. The amount of information-wise, single tag namespace and mutliple tag namespaces are not different. Though cumbersome, you can go back and force without losing information. ---++++ Switching !UserAgnostic If ={TagMePlugin}{UserAgnostic}= is 0, tagging data in _tags_WEB.TOPIC.txt consists of lines for tags put to the topic. For example, if the user =john= (login name) put the tag =foo=, the file gets the following line.
001, foo, john
Then if the user =jane= put the tag =foo=, the line becomes as follows.
002, foo, john, jane
Even if ={TagMePlugin}{UserAgnostic}= is 1, the tagging data file format remains the same. The difference is, when the tagging data file is read, each line is recognized as:
001, TAG, YOUR_LOGIN_ID
This means, if you switch ={TagMePlugin}{UserAgnostic}= from 0 to 1, all tags put by anybody are recognized as yours. Due to the way showing tags in user agnostic tagging, those tags are displayed as expected. A tagging data file remains as it is unless a tag is added or removed. Then, the file is filled with lines of the following format.
001, TAG, YOUR_LOGIN_ID
And the information of who put which tag is lost. Obviously, user conscious tagging houses more information than user agnostic tagging. So switching from user conscious to user agnostic has no problem. But the other way around causes a weird situation - all tags put to the topic A is by the user U while the topic B has tags tags put only by the user V. %ENDTWISTY% ---++ Plugin Installation Instructions This plugin is pre-installed.
