GAIA RESOURCES

Experiences in mobilizing biodiversity data – the story of HermesLite

INTRODUCTION

  • Motivation
  • HermesLite
    • Overview
    • Architecture
    • Implementation
  • Implementation at the WA Museum
  • Issues
  • Directions
slide3

MOTIVATION

  • Based on our experiences with Museums:
    • Cost had to be minimal
    • No capacity to serve data
    • Need minimal infrastructural change
    • Remote management necessary
  • Funding for WA Museum (WAM) was made available through the Australian Biological Resources Study (ABRS)
  • Under existing support arrangements to the WAM, Gaia Resources undertook the actual work
slide4

HERMESLITE

  • Overview
  • HermesLite is an application designed to help institutions serve data - in accepted formats and standards - where they don’t have the capacity or resources to do this themselves.
  • Open Source
  • Written in Java
  • Easy to manage within an institution
  • Can be remotely managed
slide5

HERMESLITE

  • Overview
  • Deployable in two configurations:
    • Data Retrieval mode: A liteweight, extensible, configurable Java application to extract and send data to…
    • Data Receiver and Storage mode: Extensible Java servlet application to receive, translate and store the data.
  • The Data Receiver and Storage mode can also act as the Retrieval mode if databases are local.

HERMESLITE

  • Implementation
  • Data Retrieval mode:
    • Unpack distribution files onto server
    • Create a configuration file for each database
    • Set up Java Wrapper Service to run appropriately
  • Data Receiver and Storage mode:
    • Install HermesLite web application
    • Extend HermesLite classes
    • Drop in handler JAR to process data
    • Install other software, (e.g. TapirLink)

  • Configurationvia a simple properties filewithvariables
slide9

HERMESLITE

  • Implementation - Data Storage
  • Extend HermesLite classes to process received rows againstchosen dataformat or standard
slide10

HERMESLITE

  • Implementation
  • This can represent a considerable organisational change in the way data is delivered
  • Be prepared to guide your organisation through this process
slide11

EXAMPLE

  • Western Australian Museum
  • Considerable discussion, demonstration, etc (“social engineering”) – still ongoing after four months
  • Selection statements for each database (restricting “sensitive” data) – being tuned all the time, curators define these
  • Darwin Core format
    • Restricted the fields being delivered
slide12

EXAMPLE

  • Western Australian Museum
  • Production went live on 11th October, 2008
  • Data services are IP restricted to OZCAM only

ISSUES

  • Two main issues struck during implementation:
  • “Social Engineering”
  • Life Sciences IDentifier (LSID) resolution
slide14

ISSUES

  • Social Engineering
  • Are all parts of the organisation ready to publish their data? Consider:
    • Management?
    • Data custodians (curators)?
    • Information Technology staff/providers?
    • Customers (both “big” and “little”)?
  • Requires considerable cultural changes to organisations, especially when revenue from data provision
slide15

ISSUES

  • LSIDs
  • A bureau service has issues with LSID resolution:
    • Originating institution WAM (www.museum.wa.gov.au)
    • Bureau service – hosting and resolving – at Gaia Resources (www.gaiaresources.com.au)
  • Difficulties in getting access to DNS records
  • Currently investigating opportunities to get around this by using the OZCAM cache as the LSID resolver
slide16

DIRECTIONS

  • Future Directions
  • Discussions with GBIF and the ALA about integrating with other provider toolkits
  • Potential use within the Museum community in Australia under the Bureau service model

ACKNOWLEDGEMENTS

  • Would not be possible without:
  • Funding from the ABRS
  • Support from the WAM, both from management and the curators themselves
  • Assistance and advice from the Faunal Collections Informatics Group members
