CAPI Update Version 1'5

1
CAPI Update Version 1.5

• CAPI Methods And Assessors Modified for Usability
• Modified JBI basObject and Metadata structure for
  Generic Approach
• No single metadata standard exist
• baseObject was defined by JBI community
• DDMS Data Discovery Metadata Standard (NCES)
• ICML Intel Community Markup Language
• IMO Intelink Mgmt Office Metadata Standard
• OMG XMI OMG XML Metadata Interchange
• others..
• Transparent Changes to Schema and Metadata for
  baseObject Utilization
• Adoption of Metadata Schema from Any Community
• Clients have option to utilize with JBI-specific
  Metadata constraints

baseObject 1.5 Syntax Changes

• PlatformProvidedAttribute Removed
• PublicationTime was PlatformProvidedAttribute now
  xsddateTime
• Coercion Removed
• Functionality Delegated to Platform
• Change in field ordering
• ltallgt tag used to make ordering irrelevant while
  maintaining cardinality of element members.
• client provided fields are optional
• baseObject should be versioned and asserted via
  MSR interface
• Support Coercion between versions

New IOType injected in MSR

• Parent types are not referenced in schema
• Metadata tags and structure not included
• Example

• ltxsdschema elementFormDefault"qualified"
  attributeFormDefault"unqualified"
  xmlnsxsd"http//www.w3.org/2001/XMLSchema"gt
• ltxsdcomplexType name"ImageData"gt
• ltxsdsequencegt
• ltxsdelement name"name" type"xsdstring"/gt
• ltxsdelement name"description"
  type"xsdstring"/gt
• ltxsdelement name"priority"
  type"xsdnonNegativeInteger" minOccurs"0"/gt
• ltxsdelement name"size" type"xsdnonNegativeI
  nteger" minOccurs"0"/gt
• lt/xsdsequencegt
• lt/xsdcomplexTypegt
• lt/xsdschemagt

New IOType injected in MSR

• New type is injected as a complete Independent
  schema
• All types have implied baseObject root ancestor
• setParent Used to Create Complex Hieratical root
  ancestors
• Benefits
• Guarantees consistency of schema content
• Hieratical Structure captured for relational
  operations
• Direct Use and Application of All Metadata
  Communities
• Metadata Example result
