Hi all,
we are happy to announce the release of version 1.0 of  Fusion, a tool for exploring and expliciting relationships in Linked Data. It:
- lists all undirected paths between two given resources (URIs), with a specified maximum length, within a RDF  graph accessed through any given SPARQL endpoint;
- allows the user to define new properties based on composing a generalization of the properties in one of the paths found,  thereby extending an existing dataset in Linked Data;
- allows the user to visualize the derived properties and its instances;
- provides a separate SPARQL endpoint with the extended data.

Fusion can be used for several purposes, such as:
- exploring existing datasets where the particular ontologies used are not well known;
- helping designers match the schema in an existing dataset to the desired schema of an application domain, making it more straightforward to build applications. This is similar to the traditional use of external views in databases;
- defining new datatype properties as functions of existing ones;
- extending existing repositories where the user has read-only access with her/his own data with full access.

Fusion is implemented as a web application and requires only a Webbrowser (Firefox, Chrome or Safari preferred). More details can be found in http://www.wis.ewi.tudelft.nl/index.php/fusion, including access to a sandbox version and a demo video.

Please try it out and send us your feedback!
Best regards,
Samur Araujo, Geert-Jan Houben, Jan Hidders (TU Delft) and Daniel Schwabe (PUC-Rio)
