Tech group submits modeling spec to W3C

A group of companies have submitted a specification!the Service Modeling Language (SML)!to the World Wide Web Consortium (W3C) for review as an industry-wide standard. The coalition includes BEA Systems Inc., BMC Software Inc., CA, Cisco Systems Inc., Dell Inc., EMC Corp., HP, IBM Corp., Intel Corp., Microsoft Corp. and Sun Microsystems Inc.

The SML specification defines a consistent way to communicate how computer networks, applications, servers and other IT resources are described!or modeled!in extensible markup language (XML). This can help businesses more seamlessly manage the services built on these resources.

"Model-based management solutions represent the new path to successfully managing the highly complex, multidomain information infrastructures emerging in today's enterprises. The multivendor SML effort is an important building block to ease heterogeneous product interoperability and management in customer environments," said Jeff Nick, senior VP and CTO, EMC.

Aside from the base SML specification, a companion specification was submitted to the W3C, the SML Interchange Format (SML-IF), which defines how to exchange SML models between applications.

With industry collaboration, SML enables a hierarchy of IT resource models to be created from reusable building blocks rather than requiring custom descriptions of every service, reducing costs and system complexity for customers. These blocks can be defined at the appropriate level of granularity for desired-state management. They include validation constraints that increase the reliability of integration thus, increasing automation. If adopted as a standard, SML will address issues of numerous methods representing the same IT resource. Currently, the use of different formats requires a translation process that can lead to the loss or misinterpretation of technical details.

SML offers support for rich constraints and alignment with XML message exchange architectures, which makes it suitable for modeling IT resources and services. SML allows developers to build modeling information for applications, IT infrastructure and services that can be used during all stages of the resource life cycle, including deployment and configuration management and resource updating. They are also useful for tactical processes such as management of service levels, availability and capacity.

The SML spec was based on Microsoft's System Definition Model (SDM), according to Kirill Tatarinov, corporate VP, Windows and enterprise management division, Microsoft.
