Beta 5.0

This is a summary of the AURIN Portal Beta 5 features and supporting backend improvements.

Data

Several hundred new datasets have been delivered in Beta5.  These include data from:

    •  Regional Australia Institute (RAI)
    •  Water and Energy datasets arising from a sub-project with CSIRO – from a variety of providers including Energy Australia and Yarra Valley Water.
    •  More from PSMA – including non-aggregate sets such as CadLite (point, polygon), Feature of Interest (point, line, polygon), Railway Line, Railway Station
    •  Arts Victoria
    •  Sustainability Victoria
    •  Australian Children’s Education and Care Quality Authority (ACECQA)
    •  Melbourne Water

Datasets from the following organisations have been significantly enhanced and extended:

    •  ABS
    •  APM
    •  City of Melbourne
    •  DEPI
    •  DPCD
    •  DoJustice
    •  EPA
    •  Grattan Institute
    •  GANexis
    •  NATSEM

Over 900 datasets are currently delivered through the Portal and more will be added as part of continuing AURIN operations.

User-interface

Beta5 has delivered the first tranche of changes following a usability review of the Portal in April/May. This includes:

    •  Some re-arrangement of on-screen components
    •  Standardisation of labelling and functional language
    •  Use of ‘group-nodes’ to facilitate geography selection.
    •  Reduced clicks needed to run and display data, tools and visualization.
    •  Better citation support
    •  Enhanced metadata presentation
    •  Enhanced handling of time-series data
    •  More rigorous presentation of terms-of-use and other licensing information
    •  More specific help link, particularly for tools operated through the portal workflow environment and support for basic wizard functionality.
    •  More control over ‘MyAURIN’ projects.

Work on the UI revamp continue through to Beta6 by which time all the recommended changes arising from the usability study will have been implemented.

Analytical tools

A number of new tools are delivered through the workflow including:

    •  Hierarchical Clustering Tree Chart Charts
    •  Population Pyramid Charts
    •  Regression Multi Simple Linear Plot Charts
    •  Regression Simple Linear Plot Charts
    •  Scatter Plot Matrix Charts
    •  Migration Analysis
      •  Stem Plot Migration Analysis
      •  Circular – All Statistics Migration Analysis
      •  Circular – Mean Direction Migration Analysis
      •  Circular – Mean Distance Migration Analysis
      •  Circular – Rayleigh Test Migration Analysis
      •  Circular – Spread Direction Migration Analysis
      •  Impact – Aggregate Net Migration Rate Migration Analysis
      •  Impact – All Metrics Migration Analysis
      •  Impact – Migration Effectiveness Index Migration Analysis
      •  Impact – Migration Effectiveness Ratio Migration Analysis
      •  Impact – Net Migration Rate Migration Analysis
      •  Intensity – All Metrics Migration Analysis
      •  Intensity – Crude Migration Migration Analysis
      •  Intensity – Crude Migration In-Bound Migration Analysis
      •  Intensity – Crude Migration Out-Bound Migration Analysis
      •  Migration Analysis – Complete Social Network Analysis
    •  Geocoder Spatial Statistics
    •  Point Join
    •  Spatialise Aggregated Dataset
    •  Bivariate Moran I Spatial Statistics
    •  DissimilarityIndex Spatial Statistics
    •  Gini Coefficient Spatial Statistics
    •  TheilIndex Statistical Analysis
    •  Generate Statistical Analysis
    •  GenerateNumeric

In addition, many tools have undergone ‘hardening’ to improve reliability, performance and presentation.

Core features

    •  Deployment of new hardware and a new virtualization platform and migration of all systems.  This will provide improved performance and reliability.
    •  The data delivery layer has been re-architected for direct streaming rather than memory buffering.  This enhances the handling of large datasets and reduces the memory footprint.
    •  Implementation of a new component to enable vector-tiling.  This component has also been packaged into an open-source release.
    •  Adoption of Continuous Delivery and Controlled Deployment as part of system building process.
    •  Greatly enhanced deployment processes that will facilitate more frequent production releases.
    •  A new data client to handle graph-like datasets (initially those relating to migration flows).
    •  Significant enhancements to internal administrative systems associated with data and metadata management, enabling AURIN to move into ‘operations’ for these activities.
    •  Enhanced Systems Integration Testing and User Acceptance Testing frameworks had been built and will be continuously revamped and enhanced so that the stability of future releases guaranteed.
