INTEROP-BP-C. RECOMMENDED TAXONOMY STANDARDS
Entities SHOULD utilize stable, published common taxonomies to enable semantic interoperability of attributes, and SHOULD use public open STANDARDS for those taxonomies when operating within communities where such STANDARDS have been established.
Most taxonomies are used within a specific community of interest, such as the InCommon community for federated higher education identity transactions. See, for example, the published set at: http://www.incommon.org/federation/attributesummary.html That example provides detailed definitions and usage notes for the attributes most commonly shared within that community, and a more formal definition model at: https://www.internet2.edu/media/medialibrary/2013/09/04/internet2-mace-dir-eduperson- 201203.html
