Can Standardization help?
• Standardization is as crucial as creating an Ontology and can be seen as the first task of knowledge elicitation
• The process requires the agreement of the community • Relevant approaches from OGF:
– Information Modeling for Computing Resources(OGSA Modeling Activities)
• Reference Model Working Group (RM-WG) (chaired by Paul Strong - e-Bay)– OGSA Resource Selection Services WG (OGSA-RSS-WG)( Donal Fellows -
UMAN/BREIN)• Knowledge Engineers can encode this knowledge in order to create the
appropriate ontologies– The objective is to increase re-usability of software– Make semantics explicit (and machine understandale)– Increase interoperability between heterogeneous Grid middleware
• Businesses are actively involved in this process– E-Bay has already encoded part (?) of the Information Model for internal resource
management (Demo shown in last GGF)• Software and Services Technical Group on Ontologies TG2
