The EDI Data Repository, through its underlying PASTA+ web services API, now supports access to data package resource maps compliant with the Open Archives Initiative Object Reuse and Exchange (OAI-ORE) standard (https://www.openarchives.org/ore/). OAI-ORE defines standards for the description and exchange of aggregations of Web resources. A resource map can be accessed from the EDI Data Repository in OAI-ORE format by appending the string “?ore” to the standard web service URL used for accessing a data package resource map. For example, to access the OAI-ORE resource map for data package identifier edi.1.1, use the following URL: https://pasta.lternet.edu/package/eml/edi/1/1?ore.
