  1. ISO/IEC 11179 Part 5 Naming and Identification Principles for Data Elements February 16, 1999 Tommie Curtis Systems Development Center SDC-0055-057-JE-8023

  2. Provides rules and guidelines for naming and identification Describes components and structure of data element identification Defines associations between identifying attributes Scope of Part 5

  3. Establish a scope for the convention Determine the authority which establishes a name Develop semantic rules for the source and content of words used in a name Formulate syntactic rules for required word order Development of a Naming Convention

  4. Develop lexical rules covering controlled words lists, name length, character set, language Set guidelines on uniqueness of names in context Development of a Naming Convention (cont.)

  5. Representation Term Object Class Term Property Term Qualifier Term What’s in a Name?

  6. Describes the form of the set of valid values for a data element Describes the form of the representation of a data element If the representation is redundant with the property term, one term or part of a term may be removed Representation Term

  7. Amount Code Count Date Group Measure Example Representation Terms • Name • Number • Quantity • Rate • Text • Time

  8. Name Representation Term Examples • Best Employee Last Name (Name) • Mailing Address State Code • Transmission Tower Height Measure • Code • Measure

  9. A component of the name of a data element which represent the logical data grouping A component of a data element which represents an activity or object in context A set of ideas, abstractions, or things that can be identified with explicit boundaries and meaning Object Class Term

  10. Employee Object Class Examples • Best Employee Last Name • Mailing AddressState Code • TransmissionTowerHeight Measure • Address • Tower

  11. A component of the data element name which expresses the category to which the data element belongs A component of the data element name which expresses a property of an object class A peculiarity common to all members of an object class Property Term

  12. Last Name Property Term Examples • Best Employee Last Name • Mailing Address State Code • Transmission Tower Height Measure • State • Height

  13. A word or words which help define and differentiate a name within the database May be attached to object class terms, property class terms, and representation class terms May be derived from structured sets of terms Should not be redundant Qualifier Term

  14. Best Qualifier Term Examples • BestEmployee Last Name • Mailing Address State Code • Transmission Tower Height Measure • Mailing • Transmission

  15. Representation Term - Code Object Class Term - Address Property Term - State Qualifier Term - Mailing Attributes of a Term Mailing Address State Code

  16. Name Context Registration Authority Identifier Data Identifier Version Identifier Identifying Attributes for a Data Element

  17. A data element shall have at least one name within a registry A data element may have additional names assigned depending on the context in which it is used Name and Context

  18. Registry Name Legacy Name Short Name Source Name Standard Name Name Context Examples • Mailing Address ZIP Code • ZIP_CODE • MAZIPCd • M_ADD_ZIP_CD • Mailing Address ZIP Code

  19. Abstract (GILS) abstract (ASN) InformationResource.Description.Text (BSR) Description (Dublin Core) Abstract (FGDC) résumé (French) Abstract (SGML Tag) Data Element Application Contexts

  20. Registration Authority Identifier - the identifier of any organization authorized to register a data element Data Identifier - the unique identifier of a data element assigned by a Registration Authority Version Identifier - the identification of an issue of a data element The International Registration Identifier (IRDI)

  21. Used to separate name components No semantic meaning Semantic meaning Special meaning for a specific language Semantics of Separators

  22. Best_Employee_Last_Name Mailing.Address.State.Code Transmission:Tower:Height_Measure Mailing Address Country Name Semantic Separator Examples

  23. Establish: Preferred and non-preferred terms Synonyms Abbreviations Component Length Spelling Permissible character set Case sensitivity Lexical Principles

  24. Source of name components Provide semantic linking of preferred terms Gives guidance in the use of homographs Shows equivalence, hierarchy, and association Allows a controlled vocabulary Use of a Thesaurus

  25. Establishes what people call a data element. People can use different names in different contexts. Expresses the primary means to refer to objects and concepts for humans So, What’s in a Name?
