Project Overview
Project overview Background and Funding ARC Linkage 2008-2011 Current Research Joint research with ETH Swiss Metadata Automation CRC 3.7 Research in Europe
Project Overview - Budget Funding requested (ARC): $126,000 per year Funding allocated (ARC): $70,000 per year Total Funding Available: $333,000 ARC $210,000 Partner Contribution $123,000 Research Fellow (50%) PhD Student Honorary Fellow (part-time) Research Assistant input, travel and other expenses ($10,000 per year)
Aim Project overview Aims and Objectives demonstrate that metadata and spatial data can be integrated within the one spatial dataset, so that when the spatial data is updated, the metadata related to that data set is also updated Objective The major outcomes of the project are development and demonstration of model driven tools for recording, updating and delivering metadata in an automated fashion.
Project overview Research Process Results of partners user business and functional specifications requirements Investigate and assess metadata standards, databases and usage Geonetwork User and Developers Group Results of CRC-SI Project 3.7 Investigate methods to integrate metadata as part of spatial data Investigate the concept of views supporting any metadata schema at any time Investigate methods to automate the process of updating metadata Vic Pilot Project NSW Pilot Project Develop prototype systems based on integrated data/metadata model Metadata/ spatial data integration Metadata delivery Automatic metadata generation
Project overview - Timelines Time line of research steps 2008 2009 2010 2011 Research Steps 1. Investigate and assess current metadata standards, databases and uses, focusing on future, dynamic and on-line requirements. July- Dec Jan- Jun 2. Investigate the process involved in integrating metadata and spatial data within the one file or database. 3. Investigate the concept of views to support any metadata schema at any time without changing the file or database. 4. Investigate the process involved in integrating metadata and spatial data within the one file or database. 5. Undertake pilot projects 6. Develop an integration model to integrate the management and updating of metadata and spatial data. PhD 1 - Develop methods to automate processes of metadata creation and updating through the development of pilot projects. 7. Develop prototype metadata generation capabilities (tools/software) for recording, updating and delivering metadata and spatial data in an integrated and automated manner. 8. Test and refine tools developed within pilot projects. 9. Publication and knowledge transfer strategy (including project web site)
Research Methodology
Project Background Ongoing research within the Centre on different aspects of SDIs Joint Research with Swiss Federal Institute of technology on metadata and data integration CRC Project 3.7- Metadata Entry Tool Collaboration with European partners
Project Background Adopted form (Najar, Rajabifard and other 2007)
Spatial Metadata Automation Research Problem Inefficiency in maintaining records Hypothesis Automating the generation and updating can bring effectiveness in publishing, finding and exploiting spatial information.
Suggested Objectives of the research project 1. Study on metadata ontology 2. Study on current practices in Spatial Metadata Tools 3. Case Study within project partners 4. Development of the concept of Metadata Automation 5. Investigation on technological trends and their impact on metadata: web 2.0, semantic web.. 6. Design and development of a prototype system for metadata
Objective 1: Metadata Ontology Metadata is critical and vital for any information infrastructure Libraries Web environment SDI Concept seems simple but efficient and effective implementation is complex
