Slide 2 - Sponsored by UK MOD Agenda » Inform about project » Milestones » Summarize changes to ISO

Slide 3 - Sponsored by UK MOD Project » Objective −Deliver update edition of ISO » ready for taking forward to ballot by 31 st March » Motivation −UK MoD desire to contribute to AP239 as an up-to-date ISO standard −Incorporate required changes identified from PLCS deployments −Ensure compatibility with ISO AP233, AP203e2 −Include additional AP203/233 modules within the original scope » Resources −Eurostep project and technical lead » Contact Rob Bodington −Funded by UK MoD

Slide 4 - Sponsored by UK MOD Application Protocol (AP) Architecture » ISO is a modular Application Protocol (AP) » Comprises of a number of modules » A module is a “building block” » Each module is a standard in its own right » Each module may be used by multiple Aps » STEP has a two level architecture −ARM – Application Reference Model » Business (?) level model −MIM – Module Interpreted Model » Traditionally Implementation level model −ARM maps to the MIM » All PLCS implementations are at the ARM level

Slide 5 - Sponsored by UK MOD Types of change » PLCS/SC4 (SEDS) modifications to PLCS modules −Deployment of the standard has identified issues to be addressed −Raised as SEDS against the standard » Only SEDS will be considered (all DEXlib issues migrated) −Mainly SELECT extensions −Allow additional assignments −Modules used by AP239 modified by AP239 » New modules created for AP239 −Some new PLCS modules will be required to address the issues −Aim to avoid scope creep! » Modules used by AP239 modified by other APs −Development of AP203e2/AP233/AP236/AP210 has led to some changes to PLCS modules −New editions of “PLCS” modules have been published » Use of Ap203e2/233 modules by PLCS −Ap203e2/233 have developed a number of new modules

Slide 6 - Sponsored by UK MOD Approach to changes » All AP239 implementations are at the ARM level −Focussing on ARM changes −Which we will map to the MIM » Ensure backward compatibility with AP239 −Where possible ….. there will be some changes » There may be an impact on PLCS templates −E.g. description −Fix these as we go » The project is managed by OASIS PLCS TOG » Consensus via OASIS PLCS TC and SC4

Slide 7 - Sponsored by UK MOD Milestones » SC4 modifications to AP239 modules understood (30 th Jan) −Agreed / changed » Scope of AP239e2 agreed (30 th Jan) −new AP239 modules identified −203/233 modules to include agreed » AP239 modules SEDS modules addressed (28 th Feb) » SC4 SEDS resolution meeting th March, Keynsham, Bath » New AP239 modules developed (20 th March) » AP239e2 + modules ready for SC4 process (31 st March) −New HTML for AP239e2 delivered as “draft” ready for submission to the ballot process » Target dates for the following ISO stages − Availability of working draft − Launch of CD or TS ballot − DIS registered at ISO (not required for TS) − FDIS ballot registered for formal approval/ Document submitted to ISO for publication cycle − Final document sent to ISO for publication after FDIS ballot, or review of ISO proof by team

Slide 8 - Sponsored by UK MOD Types of changes » SELECT extensions » Modules used by AP239 modified by AP239 » New modules created for AP239ed2 » Modules used by AP239 modified by other APs » Modules added to AP239ed2 from AP233/AP203e2
