  7. Syntactic filter • Terminology prenormalizer • Data transformation • Terminology post normalizer • Transformation viewer

  8. Main Loop Mapping System • Input • Source schema, • Target Schema • State • Source schema (session) • Target schema (session) • Current link/element (session) • Shopping Cart / Session information (session) • Mapping file pointer (persistent) • Source Instance Set (persistent) • Mapping examples (persistent) • Output - • Method • Is the main method in the Schema Mapper. Keeps in memory all the necessary information for the rest of the methods. • Call other methods • Get next undefined source link ID • Define Mappings • Save Mappings • Call mapping Browser • Go to specific source link

  9. Get next undefined source ID • Input • Current ID • Output • Next undefined ID • Method • This method is used to navigate through all the links of the source schema, by using the breadth first traversal, skipping over already defined mappings. • Call: • Get undefined mappings • Get next source ID

  10. Define Mappings • Input • Src_link • Output • Source Target Mapping ID • Method • Call method “get target_link” from Target analyzers  Return target_link • Call method “get src_domain” from Source Analyzer  Return Src_domain • Call method “get target_domain” from Target Analyzer Return Target_domain • The system finds the parameters “src_range” and “domain_range” • Call method “get src_conditions” and “get target_condition” • The systems saves it in the temporary memory. • The mappings have a flag “tmp” • The system calculates the remaining mappings to be mapped.

  11. Save Mappings • Input • tmp Mappings • Output • The remaining mappings • Method • The system chages flag “tmp” to “saved” for all the mappings. • The system calculates the remaining mappings to be mapped.

  12. Call Mapping Browser • Input • Mapping file pointer • Output • Method • Return the list of undefined mappings that is in the memory of the schema mapper.

  13. Show mapped source IDs • Input • - • Output • List of mappings • Method • Return the list of mappings that are in the memory of the schema mapper.

  14. Go to specific source link • Input • source ID • Output • - • Method • This method allows the user to navigate into specific link he choose rather than loop through each link • Call other methods • Define Mappings • Save Mappings • Show undefined mappings • Explain Rational
