Recommendations for Geospatial Metadata Standards for Digital Collections
Introduction• Hello, I’m Dorotea Szkolar! – M.L.I.S. Candidate at Syracuse University. – Specializing in Digital Libraries. – Professional background in museums and research. – Internship focus on geo-spatial metadata interoperability.
Purpose• Introduce Geospatial Metadata – Importance/GIS Technology/ Map Interfaces – Benefit to MWDL and Its Partners• Overview Analysis – Highlight Specific Interoperability Issues• Overview Recommendations – Short Term – Long Term
So What?• So What? Who Cares About Geospatial Metadata!? – Maps are lame and old news! – What does it matter having standards for spatial metadata? – Why make it the focus of my internship?
Geospatial Revolution• Geospatial Information and Map Interfaces are the next big things! – Geospatial Revolution. – Maps visualize information and patterns in ways text cannot achieve. – Several Digital Libraries achieving exciting results on this forefront. – Great opportunities for collaboration and advancement.
Example• The World Digital Library – Sleek Map Interface to Showcase Digital Collections of Partners From Around the World – http://www.wdl.org/en/• Map of State of the Internet – http://www.akamai.com/stateoftheinternet/• Tweets of the words “beer” and “church” by U.S. county – http://io9.com/5923723/tweets-of-the-words-beer- and-church-by-us-county
Other Examples• MWDL could visualize partners collections and information in new exciting ways.• But in order to achieve that, need to resolve geo-spatial metadata interoperability issues!

Analysis Highlights• Total of 50 collections use spatial refinement of Dublin core (dcterms:spatial).• On average 53 distinct values or terms utilized in each collection = wide variation.• 2/3 of collections contain spatial information somewhere in metadata = starting point to improve.
Map Interface Examples and Issues• Inconsistent formatting and vocabularies resulted in: – Semantic based errors – Interoperability issues – Display difficulties in map initiatives. – Skewed map density or items not properly displaying on the map.• Country: Britain Vs. England Vs. United Kingdom• State: Utah County Vs. Utah State• City: Salt Lake City Vs. Salt Lake County
Summary of Issues and Missed Opportunities• Reduced success of search.• Interoperability issues worsen as additional geographic regions are incorporated.• Map initiative display difficulties.• Collaboration difficulties- DPLA• Historic Names vs. Current Political Name
Recommendations- Short Tern• Mandate partners utilize spatial coverage refinement in future collections harvested by MWDL.• Complete global search and replace of simple geospatial metadata with properly formatted spatial metadata in current collections.• Hire a programmer to write scripts to automatically make assumptions when harvesting metadata.
Recommendations- Long Term• Select and enforce one standard for formatting and select controlled vocabularies (see report for candidates).• Ensure standards adopted are compliant ISO 19115.• Collaborate and experiment with interactive map interfaces and geospatial technologies.
Recommendations- Long Tern• Require partners to set timeline and make reformatting of spatial metadata part of long term institutional plan.• Fundraise and establish funds for support. – Allow partners to hire someone to reformat metadata in a timely manner. – Hiring additional staff for MWDL to assist with map interfaces and spatial based initiatives. – Build proper metadata infrastructure.
