Re: CWM --
I assume in this context, CWM means Common Warehouse Model: quote from
The recent Object Management Group ratification of the Common Warehouse Model (CWM) specification, however, represents a major step toward improved data, application, and process integration. Enterprises struggling to capture and synchronize data definitions, simplify inter-application data mobility, and track information as it flows through their information supply chain eventually will benefit from metadata standards such as CWM. Through mid-2001, exclusive metadata interchange standards in the data warehouse and analytical application domain (Informatica's MX2, Informix's MetaStage, and the Microstrategy-NetGenesis API, for example) will dissipate in favor of CWM or its opposing Open Information Model (OIM) standard from the Meta Data Coalition. During this time, even the Object Management Group's contributing vendors will struggle to fully implement CWM, instead offering only XMI (CWM's XML data type definition) interchange product features and "vendor enablement kits," including libraries of Java interfaces that abstract away direct XMI coding.
By 2002, the first fully CWM-based technologies will appear, but customers should remain indifferent to the underlying schema of products as long as the products support accepted metadata interchange standards. (See Meta Group Research Note ADS835, "Common Data Models Are for Commoners.") By 2004, robust federated metadata networks will emerge that provide ubiquitous metadata interchange among information supply- chain tools and include publish/subscribe along with traditional repository services, such as impact analysis, devoid of the need for a central metadata repository.
