Australian Centre for Ecological Analysis and Synthesis (ACEAS)

Presentation by Alison Specht, Program Manager, and Richard Thackway, ACEAS Sabbatical Fellow.

• To allow the results of novel analysis and synthesis activities to be made accessible to the public;

• To provide a platform for interactive data-compilation and validation.

Goal of portal

• Acquisition through the activities of TERN-funded research groups

• Temporary storage on secure wikis and ACEAS server

• Permanent storage on TERN server

• Sharing as per TERN protocol through ACEAS web site

Acquisition, storage, and sharing of data

• According to TERN protocol

• Modification of data through ACEAS activities creates new data, not encumbered

• Will this work???

Data licensing

• 2010: ACEAS web site and wiki facility established

• Data acquisition and handling:– 2010: one working group and one sabbatical fellow

– 2010: 3 TERN-servicing Workshops

– 2011 round 1: 5 new working groups, 1 workshop

• Expectation– 10 working groups per year, 2-3 concurrent sabbatical fellows

• Data delivery– First delivery starting with sabbatical fellow.

The stage of development

• Through the web site and secure wikis

• An example of data sourcing and interactive opportunity…

How are data uploaded and served?
