Discussion on Introduction of an Entity Category for Library Services

SWAMID have proposed the introduction of an Entity Category for Library Services with the following parameters.  


  • Entity-category URI:
  • Definition: The Library resource category applies to services that delivers resources to library users. For instance, a publisher that provides access to published articles is eligible as a candidate for this category. The library resource services are not supposed to get access to name and mail address.
  • The expected IdP behaviour is to release eptid, eduPersonScopedAffiliation and eduPersonEntitlement with the specific value “urn:mace:dir:entitlement:common-lib-terms”.

The following issues and proposals have been discussed on the list:

  • "Articles" is too narrow a definition.  Need something broader to include databases, e-books, other data sets.
  • Possibly need to be able to pass a license number to SP when site has multiple licenses?
  • Is this the same as R&S? Answer: NO, this is where you do not want to release PII.  e.g. to Elsevier.
  • The main purpose for this is a category that doesn't release PII (in the US sense)
  • How do we deal with overlaps in ECs? Entity Categories should be additive in process. Should we avoid overlaps altogether (this seems sensible).  
  • Should Entitlement be there?  Only if used?  What does this add?
  • Should ePTId be there?  Should this just be affiliation? See: on pseudonyms.  
  • "meta-attribute" conversation.
  • How does this relate to the InCommon 'Affiliation' based category?
  • Do we need a guidance document on how to cope with RequestedAttributes?
  • Andrew proposed three step process for selling entity categories to IdPs:
    •  Here <purpose> is why services in these categories are of particular value to your users;
    •  Here <attributes+behaviour/culture> is why releasing to these services is acceptably low risk;
    • Here <entity category> is how you can save yourself a lot of individual configuration effort.

Possible division between:

 Name: Library Resource Category
 Purpose: (see the formal definition of common-lib-terms)
 Attribute Bundle:
 - eduPersonTargetedID
 - eduPersonEntitlement=urn:mace:dir:entitlement:common-lib-terms (required)

 Name: Affiliation-Based Access Category
 Purpose: This service category identifies service providers that
 benefit institutional community members (faculty, staff, students, and
 others) based solely on their affiliation with their institution.
 Attribute Bundle:
 - eduPersonTargetedID
 - eduPersonScopedAffiliation (required)
