Summary: Add support for #HashTags in JSPWIKi Pages
Key: JSPWIKI-1105
URL: https://issues.apache.org/jira/browse/JSPWIKI-1105
Project: JSPWiki
Issue Type: Improvement
Components: Core & storage
Reporter: brushed
PROPOSAL – Under Discussion
See [https://en.wikipedia.org/wiki/Hashtag]
{quote} A hashtag is a type of metadata tag used on social networks such as
Twitter and other microblogging services, allowing users to apply dynamic,
user-generated tagging which makes it possible for others to easily find
messages with a specific theme or content.
{quote}
Hashtags could be a very useful feature to be added to JSPWiki, as an
additional way to categorise and retrieve information; via simple in-content
markup.
h3. Why?
You can already use regular wiki-links to connect and organise information any
way you want; eg by defining your own category pages.
But with Hashtags, a user can avoid to make intermediary category pages.
Hashtags effectively separate the aspect of tagging information from the
notion of
referring or linking wiki pages.
Hashtags have become a de-facto way of labelling information.
h3. Markup
The proposed markup is very simple; and can be used anywhere in the page
markup.
#tag1, #tag2, ....
Note: the # character is already used in wiki markup. Additional rules are
needed and backwards compatibility needs to be checked.
# Ordered Lists.
The # character is recognised as Ordered Lists markup when it appears as first
character on a new line.
When a # character does not appear at the start of a line would be recognised
as Hashtag.
# Additionally, it is proposed to render a # only as an OL item, when more
than one subsequent line starts with the # character.
This way a #hashtag could also be used as the first character on a line.
# The # character can also be used inside links, to refer to sections, or
footnotes.
But in this case there is no overlap with the use of a # for a Hashtag.
# A #tag1 would be rendered as a link to \{{ /jspwiki-url/Search.jsp?tag=tag1
}}
Core Engine
Hashtags should be stored as page metadata. And become indexed for search.
h3. Template / UI
* The INFO page would show a summary of all #hashTags on the page.
* The Search.JSP needs to be extended with a search options for TAGs.
h3. Plugins
A number of Plugins need to be extended to also support filtering on TAGs:
EG:
* SearchPlugin
* RecentChanges (show recent/trending hashtags)
* PageIndex (or HashtagIndex)
* ...
