Once you share your resources through META-Share, they will be available to others according to your licensing terms: e.g. they can be available to everyone or only to META-SHARE Members (i.e. to people who have shared their own resources) or only to academics/researchers or for academic and commercial use etc.
You have full control over the way your resources are distributed, described and documented. You can opt to let people download your resources freely, to access them via a tool/interface or to contact you in order to get them. Furthermore, by joining META-SHARE, you join the community of resource sharing, so you get to share other people's resources.
