Open format for 3d models in an OpenGL application?

I am looking to develop a game for opengl and wondering what format you recommend for using internally. The idea being to open up for contributions so some format with a lot of features, open, available and quite possibly also sample loading/rendering. Platform is java and lwjgl.org I've been looking at collada but开发者_JAVA百科 not sure it's suitable, seems to be more of an interoperability format for integration.

May I suggest reading some of the answers to the following questions:
