Hello Everyone!!
The “Glossary Application” v 0.2 has been released!!!
Previously, there was no feature in XWiki which allowed a user to add definitions and some notes for some specific words that are displayed on XWiki pages. This glossary application will make it easier for a normal user working on XWiki to add glossary/definition to some specific word/words for his own convenience to develop a quick understanding of the word given on XWiki pages. Users can use this application to define the meaning of some very specific words/acronyms/etc that are related to their domains/business (e.g. “open source”, “wiki”, etc).
You can check out the design here.
The documentation can be found here.
Suggestions/feedback regarding improvements is most welcomed. 
P.S: Currently it only supports ‘single word’ entries. Multiple word entries will be supported in future versions.
