DMWM Tutorials

The aims of these tutorials are:

• to ensure a base line understanding across all the tools and technologies in use in DMWM
• to provide a library of information useful to developers new to a subject
• to improve dissemination of information on new tools and technologies

Some tutorials may appear basic, but we hope that all attendees – including the tutor! – will learn something from each tutorial. The intention is for the tutorials to occur monthly, and to last for ~3 hours. If you would like to propose or request a tutorial send a mail to hn-cms-compTechProject. The tutorials are geared towards issues that DMWM developers may face, but they’re not restricted to that audience, and we actively encourage operations and other interested parties to attend.
