Harnessing the Geospatial Semantic Web
How can we be innovative in making collections more accessible outside of the catalog?
What technologies exist to make this happen?
Research Questions
The problem space:
Catalog records have metadata
that we want to use for display on a map interface
connected to data services with linked open data interface capabilities
Linked open data in libraries
Community of users – how it came about
Some definitions:Open dataLinked dataLinked open data
Our example
Penn State University Libraries digital collections
10 years of digitization/metadata activity
Geospatial metadata (locations, lat/long coords) inconsistently applied
Want to be able to fetch a lot of coordinates on the fly and put them in a visualization tool someplace
