Motivation

• State of the art
• Proprietary SCADA technologies
• Inefficient handling of structured numeric data
  on the Web
• Future
• Low-cost, generic architecture for web based
  SCADA applications
• New Web data type for bulk numeric SCADA data

Summary

• Generic ontology for the engineering domain is
  finally available on the Web
• Application specific ontologies for arbitrary
  SCADA applications can be build on top
• Semantic interface grants access to data of the
  Web data-type and ensures an efficient handling
  of bulk numeric data
• Substitution of proprietary SCADA systems
