  1. Sensing and Acquisition Release 1 Construction 3 Wrap-up Presentation May 19, 2011 Alon Yaari, SA Team Lead

  2. 1. Release 1 Goals • Support for end-to-end demonstration of instrument-sourced data. • UC.R1.02 Hello Instrument: Connect it to the CI • UC.R1.03 Hello Data Source: Register and connect a data source • UC.R1.18 Command an Instrument: Send it commands • UC.R1.19 Direct Instrument Access: Directly communicate with it • (No Use Case) SIAM Integration proof-of-concept • Pre-R1C3 Recap: • Objectives met by IPAA team • UC.R1.02, .03, and .18 were demonstrable by LCA/MBARI meeting in Jan 2011 • Pre-R1C3 Challenges: • Lack of formal SA team • Fluid agent/driver definitions

  3. 2. R1C3 Iteration Goals • Refined SA objectives to develop: • Common (to each instrument) instrument agent • Examples of customized instrument driver (SBE37, NMEA) • Deployable instrument simulator (NMEA GPS) • Initial SIAM adapter/driver • Defer direct-access to later release cycle • Concentrate on component interface definitions • Concentrate = Action = developing, implementing, building, demonstrating • Build on existing IPAA efforts • Concentrate on specific R1 requirements: • Instrument agent shall: Acquire data… publish to exchange Acquire metadata… publish to exchange Receive CI commands… command the instrument Manage instrument state… etc.

  4. 3. R1C3 Iteration Goals Status R1C3 Status: Areas in need of enhancement: • SIAM set-params and execute-commands • SIAM publishing to agent • Duplex communications from NMEA driver • Enhanced metadata capabilities (waiting on R2 design task) • Direct instrument access (deferred to R2) • FIPA standards (waiting on internal review)

  5. 4. Completing R1C3 Goals • NMEA Driver • How is this reflected in JIRA?As “work remains.” • How serious is this?Required for IOC. Alternative is SBE37 against real instrument. • What blocks completion?Developer’s time. • When will it be complete?IOC-ready for morning of May 23, full-duplex communications by end of transition. • Obstacles?None. • SIAM Enhancement • How is this reflected in JIRA?As “work remains.” • How serious is this?Not very. Today we can demonstrate general SIAM integration without all the details. • What blocks completion?Developer’s time. • When will it be complete?End of transition period. • Obstacles?Minor obstacle, how to implement a SIAM implementation for demonstrations and testing. • Agent / Driver Enhancements • How is this reflected in JIRA?As “work remains.” • How serious is this?Not very. Agent and driver are usable without these enhancements. • What blocks completion?Developer’s time; architectural review of FIPA integration plan. • When will it be complete?By end of transition. • Obstacles?Minor obstacle, how to implement a SIAM implementation for demonstrations and testing.

  6. 5. Transition Goals • Improving Stability and Quality • Code cleanup (agent, driver, SIAM adapter) • Documentation cleanup (interfaces, high-level overviews) • FIPA standards (waiting on internal review) • GPB-ification of messages with COI • Verification of SA Requirements • As of May 18, 2011, all Release 1 SA requirements are met • During transition, degree to which requirements are met will be improved, mainly wrt metadata • Specific Transition Tasks • General code and documentation cleanup • Organize driver code into “driver frameworks” • Metadata improvements (FIPA?) • SIAM adapter: implement set-params, execute-commands, and redirect publish to agent • SA Team All-hands transition objectives meeting to determine plan specifics for… • NMEA Driver full-duplex enhancements • PRR-specific objectives 6. Transition Plan

  7. 7. Obstacles to PRR • Obstacles to completing Transition Activities: • Access to demonstration SIAM platform • Access to SBE37 instruments • Consistency of standards and interfaces borne in other subsystems and architecture decisions (e.g., GPB) • R2 design team decisions for implementing outside standards (e.g., PUCK, etc.) • Issues with dependencies, delays, blockages: • FIPA plan approval • GPB-ification of messages with COI (has already shown to be a larger time investment than anticipated) 8. Risks
