  1. ISO Java Standardization Profile Mitsukazu Uchiyama Toshiba Corporation uchi@ap.ilab.toshiba.co.jp

  2. Objectives • Rationale and Assumption • Profiling Scheme • Taxonomy of Profiles • Series of ISO Java Documents • Conformance Related Issues • Target of SC22 Works • Proposed Next Action

  3. Rationale • ISO Java should run on ANY system. • Large Server System, Client with CRT, Embedded System, Very Tiny System ... • Some optimization is necessary. • Native compilation, Static linking, No VM, Selection of APIs ... • Profiling and Taxonomy • User can select an appropriate profile.

  4. Assumption • SMI PAS Submission • Java Language Specification (JLS) • Java Virtual Machine (JVM) • Java Core API (JAPI) • ISO Java may have some difference from SMI Java through ISO Java profiles.

  5. Profiling Scheme • Level • Application Category

  6. Level 1 (Language Specification) Virtual Machine APIs Level 2-V Level 2-A APIs Virtual Machine Level 3 = SMI JDK 1.2 Profiling Scheme: Level

  7. Profiling Scheme: Category • Indicates Application Domains

  8. Taxonomy of Profiles

  9. Series of ISO Java Docs. • Easy to Manage ISO Java Profiles • Reference = Basic Standard • Part 1: ISO Java Language Spec. • Part 2: ISO Java Virtual Machine Spec. • Part 3: ISO Java API Spec. • Profiling Scheme • TR: Taxonomy of ISO Java Profiles

  10. Conformance Related Issues • Conformance Statement on Level • Should be stated in Basic Standard. • Conformance Statement on Category • Should be stated in each Category doc. except for Reference Category.

  11. Target of SC22 Works • Basic Standard (= Reference Category) • May be some categories which are specially related to language issues: • Real time ? • Other categories should be the target of bodies outside SC22.

  12. Proposed Next Action • Continue to study the necessity of ISO Java Profiles in SC22. • If the necessity is recognized, TR of Taxonomy of ISO Java Profiles should be developed. • Profiling Scheme • Taxonomy of Profiles • Appropriate Conformance Framework

  13. Profiling Scheme • Level • Level 1 : ISO Java Language Specification • Level 2-V: ISO Java LS + VM • Level 2-A: ISO Java LS + APIs • Level 3: ISO Java LS + VM + APIs • Application Category • Reference (= Basic Standard), Personal, Embedded, Card, ...
