Geodoc Metadata Editor tool, Go-Geo! portal and ShareGeo Open spatial data repository
BackgroundBackground three decades of GIS and spatial
data capture technology
an eclectic range of academic disciplines using GIS as a research and teaching tool
considerable cost and time invested in spatial data creation
*2006 spatial data audit at 4 universities: +500 dataset files, 100s of orphan datasets
Requires a spatial data management, discovery and sharing solution delivered through portal technology and metadata metadata.
So what is So what is METADATAMETADATA?The word appears to be of Greek and Latin origin……
but metadatametadata represents something completely different……

and it’s not sun and holiday
Represents a documented and ordered summary of information that describes something, in this case, a spatial dataset.
Provides the What, Where, When What, Where, When and WhyWhy of a dataset, Ownership Ownership and and ContactContact details and Access Access andand Use Use conditions.

An incentive to encourage metadata creation?
WhereWhere is the study area represented in the data?
WhenWhen were the data collected?
WhatWhat is the dataset’s purpose?
spatial reference system? spatial accuracy? type of application? processes or algorithms used?
WhoWho supplies the data?
WhatWhat do these polygons represent?
WhatWhat attribute information is associated with these polygons?
So why metadata? So why metadata? Can you tell me fromCan you tell me fromthese files…..these files…..
WhatWhat do these SOILCLASS
values mean?
WhatWhat does this attribute mean?

protects investments of time and cost dedicated to dataset creation and development;
maintains an inventory of datasets to reduce time required to re-assess existing datasets for new and future applications;
ensures integrity of existing and new datasets using metadata as a tracking mechanism to monitor changes and edits to datasets;
reduces and minimises the disruptive effects of staff turnover;
eliminates or reduces the risk of redundancy in dataset collection;
accidental deletion of dataset files.

Metadata standardsMetadata standards provide precise specifications; enforce and ensure consistency and interoperability; define and describe metadata entities and data elements; classify and group relevant metadata elements with entities; assign structure and conditions (obligations, data type, domain).

Geospatial Metadata Application ProfilesGeospatial Metadata Application ProfilesISO 19115 standard has too many elements (300+)
* An application profile is derived from a standard and represents a reduction of the number of entities and elements.
* It should include the core element set of a standard to support interoperability across the wider geospatial community (DiscoveryDiscovery level level metadata).
* Should include elements for DescriptiveDescriptive level metadata?
* It can be extended to include elements which are best suited for a working group’s specific applications.
Example: The Biological Data Profile (BDP)The Biological Data Profile (BDP)

Why publish metadata on the Go-Geo! portal?Why publish metadata on the Go-Geo! portal?
a repository for you to store and manage your metadata thus savings in cost and time;
use metadata to announce your data and applications;
advertise (and sell?) your spatial datasets to other interested parties in academia and in the private and public sectors;
metadata in the portal can be referenced and cited for project proposals;
could be configured as an internal resource to access and share datasets.
