DZone has just published a new Equinox reference card. The idea of the reference cards is to make it easier for people to quickly get up to speed on some of the main Equinox concepts. I hope this becomes a useful resource for people wanting to know more about Equinox and OSGi. Dzone also has an interview with Jeff McAffer, author of the Refcard and Equinox project co-leader.
btw, we are also doing an EMF reference card that will be available later this month.
