Ever since I got back from Momentum it’s been work, work, work. That’s what happens when you take 4 days off to look around at what’s going on. I recall that I was going to post some more thoughts on some of the other products that I saw.

I went to David Louie’s presentation on Composer. Have to say I was impressed with what I saw. This maybe because I’ve been developing with Eclipse for a while now, so having something that integrates natively with this environment is a big plus. Whilst there are many interesting functional features of Composer I was most interested in a single slide that compared Composer with Application Builder.

First Composer doesn’t require a connection to the docbase to get your work done. You can of course import objects from a docbase, but you can also import from a docapp archive.

Secondly Composer can install your application (a DAR, similar to a DocApp in concept) into a docbase via a GUI installer but you can also use something called Headless Composer which is a GUI-less installer that runs from the command line. Not absolutely sure on the specifics at this point but possibly uses ant. David said that there are details in the documentation – I will be sure to try it out and post my findings at a later date.

This last point was of great interest to me as I’m currently investigating how to run Documentum development using a continuous integration approach. Being able to deploy your artifacts from the command line, and therefore from some overall automated controlling process is essential to making continuous integration a reality. On this note I also spoke to Erin Samuels (Sharepoint Product Manager) and Jenny Dornoy (Director, Customer Deployments). I hope that the sharepoint web parts SDK that is likely to integrate into MS Visual Studio will also have support for a headless installer, and also that Documentum/EMC products generally support the continuous integration approach.
