The CMS Glossary has 585 proposed terms. 230 now have extensive definitions.
We have prototyped the glossary-as-a-service feed for several CMS-related sites. Editorial details are at CM Professionals > Glossary
It is playing now on Content-Wire in the UK.
The CMS Glossary on CMS Wiki is a controlled vocabulary of terms used by CM Professionals, a content management community of practice.
It is also a demonstration of the CM best practice called single-source publishing.
CMS Glossary definitions are written using collaborative authoring tools with version control at our companion site CMS Wiki.
Definitions are then extracted by a web service (a connector or adapter) that converts them to syndicated information feeds suitable for use on any CMS-related site. They can appear in an iframe, or open a new popup glossary window with a CSS stylesheet to match a site.
Instructions for embedding links in your text that will call these info feeds are available here.
