'''System for Cross-___domain Identity Management''' ('''SCIM''') is a standard for automating the exchange of user identity information between identity domains, or IT systems.
One example might be that as a company onboards new employees and separates from existing employees, they are added and removed from the company's electronic employee [[Directory service|directory]]. SCIM could be used to automatically add/delete (or, [[account provisioning|provision/de-provision]]) accounts for those users in external systems such as [[Google Workspace]], [[
In addition to simple user-record management (creating and deleting), SCIM can also be used to share information about user attributes, attribute schema, and group membership. Attributes could range from user contact information to group membership. Group membership or other attribute values are generally used to manage user permissions. Attribute values and group assignments can change, adding to the challenge of maintaining the relevant data across multiple identity domains.<ref name="SCIM-19">{{cite book |author = Internet Engineering Task Force, Network Working Group|title = System for Cross-Domain Identity Management: Core Schema|version = Draft 19|date = May 11, 2015|url = http://tools.ietf.org/html/draft-ietf-scim-core-schema-19|accessdate = 2015-05-17}}</ref>
The SCIM standard has grown in popularity and importance, as organizations use more [[Software as a service|SaaS]] tools.<ref name="SCIMming" /
SCIM uses a standardised [[API]] through [[REST]] with data formatted in [[JSON]] or [[XML]].<ref name="SCIM-19" />
==History==
The first version, SCIM 1.0, was released in 2011 by a SCIM standard working group organized under the Open Web Foundation.<ref name="simplecloud">{{Cite web|url =
SCIM 2.0 was completed in September 2015 and is published as IETF RFCs 7643<ref>{{Cite journal |url= http://tools.ietf.org/html/rfc7643 |title= RFC 7643: System for Cross-___domain Identity Management: Core Schema |date= September 2015 |website = ietf.org |publisher= Internet Engineering Task Force |last1= Hunt |first1= Phil |last2= Grizzle |first2= Kelly |last3= Wahlstroem |first3= Erik |last4= Mortimore |first4= Chuck }}</ref> and 7644.<ref>{{Cite journal |url= http://tools.ietf.org/html/rfc7644 |title= RFC 7644: System for Cross-___domain Identity Management: Protocol |date= September 2015 |website= ietf.org |publisher= Internet Engineering Task Force |last1= Hunt |first1= Phil |last2= Grizzle |first2= Kelly |last3= Ansari |first3= Morteza |last4= Wahlstroem |first4= Erik |last5= Mortimore |first5= Chuck }}</ref> A use-case document is also available as RFC 7642.<ref>{{Cite journal |url= http://tools.ietf.org/html/rfc7642 |title= RFC 7642: System for Cross-___domain Identity Management: Definitions, Overview, Concepts, and Requirements |date= September 2015 |website= ietf.org |publisher= Internet Engineering Task Force |last1= Li |first1= Kepeng |last2= Hunt |first2= Phil |last3= Khasnabish |first3= Bhumip |last4= Nadalin |first4= Anthony |last5= Zeltsan |first5= Zachary }}</ref>
The standard has been implemented in various [[Identity management|IdM]] software.<ref>{{Cite web |url =
The standard was initially called '''''Simple Cloud Identity Management''''' (and is still called this in some places), but the name was officially changed to ''System for Cross-___domain Identity Management (SCIM)'' when the IETF adopted it.<ref>{{cite web |last= Hunt |first= Phil |title= Standards Corner: SCIM and the Shifting Enterprise Identity Center of Gravity |website= Oracle Fusion Middleware (blog) |publisher= Oracle |date= February 27, 2014 |url = https://blogs.oracle.com/fusionmiddleware/entry/standards_corner_scim_and_the | accessdate= May 17, 2015 }}</ref>
[[Interoperability]] was demonstrated in October, 2011, at the Cloud Identity Summit, an [[Identity management|IAM]] industry conference. There, user accounts were provisioned and de-provisioned across separate systems using SCIM standards, by a collection of [[Identity management system|IdM software]] vendors: [[Okta (identity management)|Okta]], [[CyberArk]], [[Ping Identity]], [[SailPoint]], [[Technology Nexus]] and [[UnboundID]].
SCIM is the second standard for exchanging user data, but it builds on prior standards (e.g. [[Service Provisioning Markup Language|SPML]], [[Portable Contacts|PortableContacts]], [[vCard]]s, and [[LDAP Data Interchange Format|LDAP directory services]]) in an attempt to be a simpler and more widely adopted solution for cloud services providers.
The SCIM standard is growing in popularity and has been adopted by numerous identity providers
