Enterprise Technical Reference Model - Service Oriented Architecture (ETRM v. 5.0)
The Enterprise Technical Reference Model (ETRM) provides an architectural framework used to identify the standards, specifications and technologies that support the Commonwealth's computing environment. The ETRM identifies both the current state and the target state of the Commonwealth's computing environment. Ongoing implementation of the target state identified within the ETRM will result in a Service Oriented Architecture (SOA) for the Commonwealth that uses open standards solutions where appropriate to construct and deliver online government services. This version of the ETRM effective September 16, 2008 updates content published in version 4.1. This version includes enhancements to the ETRM's format for accessibility and usability as well as provides additions and updates to existing language and technical specifications. The ETRM continues to be a work in progress.
