Aircraft Based Observations - Metadata Repository (ABO-MR) Initial Online Training Stewart Taylor - Consultant/ABO Expert 15th February 2024
Content Purpose of the ABO-MR System Structure Main Features
Purpose of the ABO-MR A centralised global metadata repository to support ABO (initially proposed as a component of OSCAR/Surface development), but then outsourced under co-ordination with WMO. A secure web based system to support provision and maintenance of current and historical ABO systems metadata. The system to be operated/maintained remotely and capable of interfacing with OSCAR/Surface (component of WMO RRR).
Purpose of the ABO-MR System will allow submission and maintenance of ABO metadata by WMO Members operating ABO systems in compliance with WMO- No.1200, Guide to Aircraft-Based Observations, Appendix D and also align with WIGOS Metadata Standard . In summary, the ABO-MR will provide (and allow the maintenance of) current and historical ABO metadata.
System Structure Functionality Metadata repository (MR) storage of metadata elements, controlled metadata entries, Programme/System/Fleets etc, historisation of metadata, changes, corrections and updates, compliance with WMO-No.1200 and WIGOS Metadata Standard. Infrastructure HTTP web services, API protocols Database operations e.g. back up.
System Structure Software COTS database software, Supports API connectivity and database transactions. Secure user interface (Admin and Programme Manager) Secure login, ownership of metadata, Input and maintenance of metadata (database transactions), Access to metadata and data displays with data export capability. Public user interface Access to non-restricted metadata and data displays with data export capability.
System Structure Angular - display of interfaces for Admin and Programme Manager, Azure AD B2C - authentication of users, using WMO credentials, Django - handling backend tasks, communication (UI and database), Django RF - building web APIs, Python packages - development of code/backend tasks, PostgreSQL - database, Mapbox - display of airport locations in map viewer.
Main Features The following slides provide a summary of the system features - this will be expanded on by the Wishtree system demos. Once User is logged in Home Page Various menus and options for users, dropdowns to select different metadata options e.g. Programme, System, Fleet etc, Various Reports e.g. Map view shows vertical profiles for airports and selected programmes; Tabulated view shows airport listings with fleets and profile distribution information. The tabulated airport listings can be downloaded.
Main Features User Management Admin and Programme Manager secure log in (Azure AD), Admin - create users, programmes, fleets etc, and all functions of Programme Manager, Programme Manager - create, update and edit metadata records assigned to PM, Public User - read-only access to ABO-MR, can view metadata and export non-restricted data fields.
Main Features Admin User Interface User Management - view, edit and activate/deactivate users, Programme - add, view, edit and delete Programmes, Systems - view and edit Systems, Data Originating Centre - add, view, edit and delete DOC, Airports - only Admin can add airports to the ABO-MR, Sensors - view, add, edit and delete sensor details, Aircraft and Fleets - view, add, edit, delete and update historisation.
Main Features Programme Manager User Interface Programme - view Programme details e.g. Focal Point PM etc, Systems - view System details, e.g. Programmes and Fleets, Data Originating Centre - add, view, edit and delete DOC, Airports - view airport details, Sensors - view, add, edit and delete sensor details, Aircraft and Fleets - view, add, edit, delete and update historisation.
Main Features Reporting User Interface 1. Programmes Map - view locations of Programmes, Vertical Profiles Map - airport locations with details of Programmes, Fleets and Profiles, Systems - list of systems with associated fleet details, Fleets - list of fleet details and associated irports and aircraft, Aircraft - list of aircraft details and sensors assigned, Airport - list of airport details and associated Programmes and Systems, System Software - list of software details and associated fleets.
Main Features Reporting User Interface 2. All the above options have a concertina view which allows the user to expand the details where applicable. Metadata Filter - allows user to search for a period of time, Filtering of the Programme, System and Fleet options will alter the Map and Tabular viewers accordingly. Legend Filter - allows selection of Profiles to be displayed. User Guide - link to the latest ABO-MR User Manual.
