© 2006 Open Grid Forum 3 The Group Weekly phone meetings Group functions well with an active core of sufficient size to be effective 3 more sessions this week Working sessions in place of our usual F2F Currently only Oracle provides the big vendor input as IBM people have moved on in various ways New people (especially IBMers or similar) very welcome
© 2006 Open Grid Forum 4 Base specification Base Specification released on the 3 July 2007 as GFD.110: http://www.ogf.org/documents/GFD.110.pdf http://www.ogf.org/documents/GFD.110.pdf During implementation work small errors and omissions have been noted. Listed in our Wiki A new version of the specification being produced with editorial changes in good time for the 6 month cut-off.
© 2006 Open Grid Forum 5 From our top page Suppose you need to be able to channel the flow of data from thousands of sources to thousands of destinations flexibly. … applications such as alerting from stock tickers; threat/monitoring sensors and actuators; or simply matching buyers and sellers … … dynamic way to match the sources and destinations of the streaming data in a flexible manner... INFOD lets publishers and subscribers of information advertise their requirements and capabilities with their own … vocabularies, and matches them … plumbing for communities of interest based on types of content.... you need a way to react dynamically as the condition or state of the producers and consumers of data changes. INFOD takes into account such situations... INFOD tells the sources where to send and how to filter information for a particular destination … sources and destinations communicate directly with each other... … "Valued Information at the Right Time". Consistent with GMA (GFD.7) 2000-2002
© 2006 Open Grid Forum 6 Example: Looking for a Car Car buyers like to be aware of all cars of interest from those dealers who are located close by and who have good BBB and service ratings. Instead of receiving pre-canned information buyers like to specify which information is relevant to them. Car dealers too like to put restrictions on potential buyers; they like to communicate only with those buyers who have good credit rating and do not live too far away. Car dealers and buyers like to specify their needs in a terminology that is meaningful to their community.

© 2006 Open Grid Forum 15 Data Sources Data Vocabularies only define the structure of the data Data Sources represent specific data and link data vocabularies to publishers
© 2006 Open Grid Forum 16 Property Vocabularies Property vocabularies define user defined properties of INFOD objects Property vocabularies must be based on XML Property vocabularies can be associated to publishers, vocabulary associations, consumers and subscribers Information related to property vocabularies can be used to identify acceptable/desirable properties of INFOD object This is managed by constraints Constraints provide mutual filtering support
