SPML (Services Provisioning Markup Language) is an Extensible Markup Language (XML)-based language that facilitates the exchange of provisioning information among applications and organizations, corporations, or agencies. Provisioning, according to the technical group providing support for it, is "the automation of all the steps required to manage (setup, amend, and revoke) user or system access entitlements or data relative to electronically published services."
SPML was first demonstrated publicly in 2003 by a technical working group of the Organization for the Advancement of Structured Information Standards (OASIS). SPML Version 1 is built on the OASIS Directory Services Markup Language (DSML) Version 2, which is an XML representation of the Lightweight Directory Access Protocol (LDAP). SPML is expected to join a family of standards designed to ease the implementation of Web services, and to establish interoperability among provisioning systems that allow organizations to securely create end-user accounts for Web services and applications from a single point in an organization.
A single SPML request message can be used to simultaneously create user accounts in multiple provisioning systems. Deprovisioning, such as when an employee leaves a company, is done by closing access accounts. This eliminates orphaned accounts and prevents ex-employees from gaining access to customer systems.
