GR000: Presented in Fremantle on 20th October, 2008
INTRODUCTION
• Motivation
• HermesLite
• Overview
• Architecture
• Implementation
• Implementation at the WA Museum
• Issues
• Directions
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
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
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)
HERMESLITE
Implementation - Data Retrieval
• Configuration
via a simple
properties file
with
variables
HERMESLITE
Implementation - Data Storage
• Extend
HermesLite
classes to
process
received
rows against
chosen data
format or
standard
HERMESLITE
Implementation
• This can represent a considerable organisational
change in the way data is delivered
• Be prepared to guide your organisation through
this process
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

• 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
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
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
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
