I am trying to get a sense as to how much work I am thinking of getting into.

EMF does serializations to and from XMI and XML right out of the box. I have used a product that did the same thing with JSON. I have seen a product that claimed it would do RDF. I have a special need to serialize to a special format (HLA's FOM file, if anyone knows what that is.)

My question is, how big of a project is such a thing likely to be? Has anyone ever written a custom serializer?

My output is a nested structure similar to XML but with different delimiters.

I hope I've been clear.

If your requirement is really very similar to XML, a shell regex might do, e.g. sed. Perhaps a simple Java aided regex is necessary. More likely a simple model-blind SAXParser and direct output. But it really depends on the format of xmi:idrefs.

You could override EMF serialization, but EMF has so much power/complexity for XSD etc that you will be struggling with unhelpfully flexible code unless you really want that power.
