Geospatial Librarian

The GeoBlacklight schema is an extension to Dublin Core specifically for geospatial records. This schema was described by its creators, Darren Hardy and Kim Durante, in the 2014 Code4Lib article, " A Metadata Schema for Geospatial Resource Discovery Use Cases ." File Transformations Typically, geospatial librarians who wish to create GeoBlacklight JSON files are generating them from existing records in other metadata standards. This can be accomplished with XSLTs that transform the records. Here are links to XSLTs for different standards: XSLTs written by Kim Durante FGDC to GeoBlacklight ISO 19139 to GeoBlacklight MODS to GeoBlacklight XSLT written by Kevin Dyke ISO 19139 (GeoNetwork) to GeoBlacklight ============================== Screenshot of customized instance of Omeka - item edit page. Form Based Editor for GeoBlacklight For some workflows, a form based editing tool might be preferred for creating GeoBlacklight metadata.  This is t...

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a framework that can be used to pull metadata records from enabled repositories.  The records are transferred in a simple Dublin Core XML format.  This is an open and well documented framework, and there are many tools available that can perform metadata harvests. The method for requesting the records uses a URL that has been set up by the repository.  Refining the request can come in the form of “Sets” or sub-collections, and “From” or “Until” for records added between a period of time.  Some repositories may have published their OAI-PMH URLs, but others may only release them upon request. The records are harvested as Dublin Core XML, but use a dedicated schema ( http://www.openarchives.org/OAI/2.0/oai_dc.xsd ), prefix (oai_dc), and namespace ( http://www.openarchives.org/OAI/2.0/oai_dc/ ) .  These may need to be transformed if importing the records into an editor.

Note: This is the first in a series of posts that examines the next stage of the CIC GDDP project: incorporating maps. 18th Century Map of Ceylon (Sri Lanka), held at the John R. Borchert Map Library, University of Minnesota One of the exciting aspects of the CIC Geospatial Data Discovery project is that we are gathering geospatial resources in the form of both GIS records and scanned map images. These two types of resources differ from one another in terms of repositories and metadata standards. Most of our GIS records are from public agencies, such as a state’s department of natural resources and are described with the FGDC or ISO standard. Most of the maps are from University libraries and are described with the MARC or Dublin Core standard. Combining these resources into one portal presents challenges in to form of choosing compatible metadata standards and appropriate tools. The initial decision of the task force was to convert all resources into the ISO19...
