Purpose S-101 represents a major step forward in product specifications for Electronic Navigational Charts. This consists mainly of new feature types to overcome existing issues (e.g. overuse of caution areas) and improved functionality leading to more efficient data handling. As a result, TSMAD is proposing a phased approach for the development, testing, and release of S-101* *Approved TSMAD 19
S-101 Software Development Lifecycle Planning – Phased Approach Analysis – Stakeholders Input Design – Test Beds Implementation Maintenance
Benefits of a Phased Approach Iterative Development – Each iteration is usable and testable Controlled change – Enables a test of the change control process to both S-101 and S-100 Enables smooth migration – Manageable change Will mitigate type approval concerns – Ensure that S-101 catalogues are not software or hardware updates Does not try and solve everything at once Enables stakeholders to phase their development implementation of S-100 based product specifications
Phases Phase 1S-57 ENC Content Equivalent Phase 2Enhanced Packaging and Data Loading Phase 3Extending the S-101 model Phase 4Scalability
Phase 1: S-57 ENC Content Equivalent S-101 draft 0.1 contains: – Feature Catalogue includes only those features and attributes that are currently in S-57 3.1.2 XML – Portrayal Constrained by S-52 PL 3.4 – General Feature Model – Includes the S-100 geometry – Compound curves – Will contain updates -.001,.002 – Use of the new 8211 encoding Deliverable: S-101.000 file and updates (no catalogue file)
Phase 1: Activities Feature Catalogue – Create XML Feature Catalogue – Create XSLT Style Sheet Information types will be utilized for the new 8211 Begin developing Version 1 Data Capture and Classification Guide Develop draft 0.1 test dataset
Phase 1: Test ActivityTest Feature Catalogue (FC) Compare Style Sheet output with S-57 Object Catalogue Test Dataset (TDS)compare content of S-64 to S-101 test dataset Put all three components (TDS,FC, PC) together to ensure that they work. (OEM) updating scenarios (dataset only)
Phase 1: Benefits Proof of Concept and validation of S-100 – Feature Catalogue is exchanged as data Utilization of the new 8211 encoding Creation of an S-100 compliant product specification – Template for other S-100 product specifications Prove that an S-57 based product can be built using S-100
Phase 2: Enhanced Packaging and Data Loading Mechanisms S-101 draft 0.2 contains: – New support file formats and management – New file naming conventions – Populating exchange sets Metadata Improved Display Scales for ECDIS loading – Updating Scenarios – Includes text file updating – Portrayal Catalogue is introduced Deliverable: Complete Exchange Set including updates
Phase 2: Activities Define new file formats (XHTML, JPEG etc.) Define new naming convention Create multiple test data sets utilizing the enhanced display scales Create enhanced updating scenarios Enhance metadata and data discovery
Phase 2 test plan ActivityTest Create complete exchange set Put all three components (TDS,FC, PC) together to ensure that they work. (OEM) Enhanced Display Scales Test Data Loading utilizing the revised display scales Updating ScenariosTest support file updating Test dataset updating Test updates Data DiscoveryTest improved data discovery
Phase 2: Benefits Demonstrate improved functionality of S-100 Prove that this process is supportable Improved data delivery – Improved data discovery – Easily Accessible Metadata – Support File Improvements (xhtml, jpeg) Continuous dialogue between IHO and stakeholders Opportunity to test potential efficiencies Platform to demonstrate new capabilities
Phase 3: Extending the Model S-101 draft 0.3 contains: Utilization of extended model capabilities – Introduce Complex attributes – Introduce Information Types – Multiple language support Explore the use of cartographic attributes for enhanced display Continue to update the Data Capture and Classification Guide to support enriched content Issue a new version of the Feature Catalogue and Portrayal Catalogue with content changes Deliverable: Phase 2 deliverables with extended content and updated Feature Catalogue and Portrayal Catalogue
Phase 3: Activities Feature Catalogue – Create XML Feature Catalogue – Include Complex attribute – Include Information type (enhanced language support) – Include Cartographic Attributes Portrayal Catalogue – Create XML Portrayal Catalogue – Include updated portrayal to reflect extended feature catalogue – Utilize Add, Modify and Delete in the Portrayal Catalogue Deliverable: Complete Exchange Set, updated Feature and Portrayal Catalogues, Data Capture and Classification Guide
Phase 3: Test Plan ActivityTest Feature CatalogueLoad Catalogue from phase 1 and then update using Phase 2 Catalogue to test feature catalogue maintenance Portrayal CatalogueLoad Catalogue from phase 1 and then update using Phase 2 Catalogue to test portrayal catalogue maintenance Exchange SetTest that new features, updates, and metadata load, operate and display correctly Data Capture and Classification Guide Compare the Data Capture and Classification Guide to the Feature Catalogue
Phase 3: Benefits Prove maintainability – Feature Catalogue updating – Portrayal Catalogue updating Enhanced language support Improved Update process Prove that the catalogues are machine usable data Data Quality and Usability improvements – Complex attributes will clean underlying data
Phase 4: Scalability S-101 draft 0.4 contains: – Introduce the concept of Scale Independent and Scale Dependent Datasets Create an information object dataset that contains all the information objects for every dataset associated with it. – Finalize Version 1 of the feature catalogue and portrayal catalogue Additional complex attributes Additional information types Deliverable: Version 1.0 of S-101 Test Dataset and test datasets containing scale independent and scale dependent data
Phase 4: Activities Finalize Version 1 Feature Catalogue Finalize Version 1 Portrayal Catalogue Finalize Version 1 Data Capture and Classification Guide Creation of S-101 Version 1.0 Test dataset Create Test Data containing scale independent and scale dependent data.
Phase 4 Test Plan ActivityTest Scalability of Feature Catalogues and Portrayal Catalogues Load catalogues from Phase 3 then update utilizing catalogues from Phase 4 Scale Independent and Scale Dependent data test loading into systems, test updating mechanisms.
Phase 4: Benefits Test the continued maintenance of the standard Improves the ability of data producers to reflect the real world – Caution Area Reduction
