FGDC metadata from Harvard Geospatial Library originated in XML format so no converting of this format was necessary prior to processing by the BIBFRAME converter described below.

BIBFRAME Conversion

The bib2lod project was used as base code for converting both the HFA and FGDC XML data. An extension of this base code was made for each of these input formatformats. This custom Custom code for each project was necessary due to significant difference between the datapoints available for each format.

During the development process extensive test cases were written for each format type and vetted a domain expert.
