Rhizomer

Rhizomer is a web application that facilitates publishing, querying, browsing, editing and interacting with semantic data.

Concretely, it gives support to 7 typical tasks of Semantic Web end-users. Here, end-users stand for users with no or limited knowledge about the Semantic Web. Particularly, we don't include domain experts, which might neither have knowledge about the Semantic Web but whose main task is to work with ontologies. The end-user tasks supported by Rhizomer are:

• Search: pose a semantic queries using HTML forms, which are dynamically generated and user customisable, and obtain resource descriptions rendered as HTML.
• Browse: navigate through the graph of data retrieving fragments of manageable size and rendering them as interactive HTML.
• Annotate: provide new semantic metadata describing a resource, or edit existing one, using HTML forms that assist the user during this process.
• Mashup: mix two or more pieces of metadata about common resources, or resources similar in some sense, e.g. they all have geographical coordinates or are situated in time and can be placed together in a map or timeline respectively.
  
• Share: upload, update and delete pieces of content (HTML, images, videos, documents, etc.).
• Map: define simple mappings between concepts from different ontologies.
• Transact: generically, this task includes any user action that change the state of a real-world entity or of a resource in a system outside Rhizomer. Rhizomer features mechanisms that facilitate integrating external web services.

A preliminary version of Rhizomer is available for download. Please, treat it with care because it is very preliminary ;-)
