Linked Open Graph (http://log.disit.org , the LOG.DISIT.ORG tool and service) is a unified solution for problems and cases. Linked Open Data, are complex structures to be understood if you just access to them for their exploitation and reuse. • A tool for browsing LOD selecting relationships among URI elements and their attributes can be a solution for developer for data and knowledge engineers. Therefore, services that allow you to insert URI of LOD to navigate on their structure over multiple RDF stores and LD sources are very useful tools for shortening the development phase. Portals and services need to cope with relationships among Users, Contents and external sources. Thus the users need to have a clear view about the relations among entities to better understand context at a glance, such as: • Who has provided a given content: group, user, etc.; How a given content has been used by other users: promoted, played, uploaded, updated, etc.; Which are the geographical locations mentioned by a content, and where is located, may be connected with external geoname, and GPS coordinates; Which are the person names cited into a content: vip names related to dbPedia, users of the portals, other person names cited in many other content; Who has been contact with how, what they have done, etc. The users need to discover and navigate among these relations by selecting those of interest for each specific case. For these cases the LOG.DISIT.ORG provides algorithms and tools to solve the problem dynamically showing the relationships and resolving connections. The Users can play with graph elements moving and zooming, turning on/off connections, searching, filtering and expanding, exploring and playing to see more information, exploiting connection with other RDF Stores, LOD/LD, et c. Social Graph is a simplified Linked Open Graph for social networks, and example of its usage is in www.ECLAP.eu
