Extension:Halo Extension

The Halo extension is an extension to Semantic MediaWiki (SMW) and has been developed in order to facilitate the use of Semantic Wikis for large communities of users. It consists of a diverse toolset that increases the ease of use of SMW features and advertises the immediate benefits of semantically enriched contents.

Features
Halo enhances SMW by providing intuitive graphical interfaces that facilitate the authoring, retrieval, navigation and organization of semantic data in SMW.

It basically comprises:
 * Semantic Toolbar, allowing to quickly inspect, create and alter the semantic annotations of a wiki article
 * Advanced Annotation Mode, for annotating contents semantically in a WYSIWYG-like manner without having to cope with the wiki source text
 * Auto-completion, suggesting entities or data existing in the wiki while typing (e.g. when annotating in the wiki-text or filling in input fields)
 * Graphical query interface, empowering users to easily compose queries and preview query results with different output formats
 * Ontology browser, enabling intuitive browsing and changing of the wiki's ontology and lookup of instance and property information
