== IDEF Functional Model ==&lt;br /&gt;
&lt;br /&gt;
The IDEF Functional Model, published by IDESG as an approved version 1.0 here: [https://workspace.idesg.org/kws/public/download/81/IDEF-Functional-Model-v1.0.pdf&amp;amp;wg_abbrev=idesg_document| PDF link], describes identity management activities in a multi-layer model which includes a taxonomy of five types of Core Operations:  &lt;br /&gt;
* [[IDEF Functional Model REGISTRATION|REGISTRATION]]&lt;br /&gt;
* [[IDEF Functional Model CREDENTIALING|CREDENTIALING]]&lt;br /&gt;
* [[IDEF Functional Model AUTHENTICATION|AUTHENTICATION]]&lt;br /&gt;
* [[IDEF Functional Model AUTHORIZATION|AUTHORIZATION]]&lt;br /&gt;
* [[IDEF Functional Model INTERMEDIATION|INTERMEDIATION]]&lt;br /&gt;
&lt;br /&gt;
These activities and services collectively are defined as &amp;quot;[[IDEF Glossary DIGITAL IDENTITY MANAGEMENT FUNCTIONS|Digital identity management functions]]&amp;quot; in IDESG&amp;#039;s [[Baseline_Functional_Requirements_v1.0|Baseline Functional Requirements]].&lt;br /&gt;
&lt;br /&gt;
In addition to that list of Core Operations, the Functional Model defines a series of Functional Roles, as well as similar lists of activities and roles for Governance and Accountability, Interperability and Administration.&lt;/div&gt;</summary>
