Enabling Grids for E-sciencE INFSO-RI EGEE Sofia 28/06/05 6 App 2 - Ovid: Grid Browser Ovid Ovid is an extensible browser for Grid-related information. OvidThe key goal of Ovid is to support the seamless navigation of users in the Grid information space. FeaturesFeatures –A set of navigational primitives, which are designed to cope with problems such as information overloading and are made available through the graphical user interface of Ovid. –A small set of views, which present the end-user with high level, visual abstractions of Grid information. –Support for embedding and implementing hyperlinks that connect related entities represented in different information views. plug-in mechanism –A plug-in mechanism, which enables the seamless integration with Ovid of third-party software that retrieves and displays information from various sources.

Runs on distributed machines in different testbeds –It downloads Web Pages according to user preferences. Successful test runs on the Grid and local testbed –7 processors –GB of input data –Runs continually Need to connect to origin web servers and download web pages.
