AbstractThe PORTAL‐DOORS Project (PDP) aims to develop the Nexus‐PORTAL‐DOORS‐Scribe (NPDS) Cyberinfrastructure as a distributed network of data repositories that communicate with each other using a common message exchange standard. These data repositories include a collection of servers with a system of registries, directories, and diristries for diverse resources including bibliographic information records. Examples of resource metadata representations can be viewed at PDP participating websites. Until now, PDP has not supported convenient import or export of bibliographic records to or from any of the common bibliographic standards. In this report, we describe our progress on our new PDP utilities for interoperability between the format for NPDS records and various bibliographic formats such as BIBFRAME, MARC, RIS, and BibLaTeX. We will detail the import process when using a converter that transforms bibliographic citations in other formats and stores them in an NPDS diristry. Improved interoperability for conversion between bibliographic records in other traditional formats with the NPDS format will support a variety of use cases that require either lexical and/or semantic parsing of cited references.
