This document attempts to identify the differences between the InCommon Research & Scholarship Category and the REFEDS Research & Scholarship Entity Category. The latter was formally adopted by the REFEDS community in February 2014. The REFEDS R&S specification was revised to V1.2 on November 28, 2014.
[Item 1] Here is the relevant phrase from the Participation Agreement:
Participant understands that it may not permanently store nor share or disclose or use for any purpose other than its intended purpose any identity information that it receives from another InCommon Participant without express written permission of the other InCommon Participant.
Compare the above passage with the following quote from the REFEDS R&S Category specification:
Service Provider claims that it will not use attributes for purposes that fall outside of the service definition.
The primary distinction is that the former is included in a signed legal agreement while the latter is self-asserted by the service owner. See, for example, the R&S application form used by InCommon.
[Item 2] While the InCommon R&S Category keeps the door open to commercial services, the REFEDS R&S Category seems to explicitly rule them out.
[Item 3] Prior to October 27, 2014, the InCommon R&S Category had the following requirement:
a Service Provider that engages subjects in experiments that require specific oversight is not eligible for the R&S Category.
This refers to research that would require Institutional Review Board (IRB) approval. Following the recommendations of both the Technical Advisory Committee and the Steering Committee, this requirement was removed from the InCommon R&S Category on October 27, 2014.
[Item 4] All but one InCommon R&S SP already has an
mdui:InformationURL in metadata so this particular difference between the two specifications is irrelevant.
[Item 5] InCommon already requires both technical and administrative contacts in metadata, for all SPs and IdPs.
[Item 6] The REFEDs R&S specification has two requirements regarding requested attributes in metdata:
The Service Provider provides requested attributes in metadata.
Service Providers SHOULD request a subset of R&S Category Attributes that represent only those attributes that the Service Provider requires to operate its service.
For clarity, these two requirements are broken into three parts on the R&S application form:
In particular, the latter is a strict requirement for all InCommon R&S SPs, which goes beyond the REFEDS R&S requirements.
Obviously, the entity attribute value for InCommon R&S is different than the entity attribute value for REFEDS R&S. In the short term, the goal is for all InCommon R&S SPs to have a multivalued entity attribute in metadata, that is, each SP will satisfy the requirements of both InCommon R&S and REFEDS R&S (which is possible since the gap between them is small). Once all R&S SPs have a multivalued entity attribute in metadata, all InCommon R&S IdPs will be encouraged to migrate their configurations to the REFEDS R&S entity attribute, that is, to release the R&S attribute bundle to all R&S SPs, globally.
