What is OMA? When we look at the logo we can see four disjoint rings. Each of these rings stands for an archive area. There is a yellow ring in the center to combine all these areas by defining a common set. This is the new context on a meta level. If we have an understanding of what ORANG is about, we could say, that OMA is the same thing on a meta level. This means, that - if you remember this ring logo - the yellow ring represents a node in the meta-level network and each other ring represents a node in a single network. Archiving and publishing are working hand in hand. While we have plentyfull information on the archive site, on the other side we have a deficiency of published context. To solve that, OMA combined them and bring the raw archive material closer to the context giving editors.
