A quick look at the MDE keywords appearing in job offers show that UML is still by far the most common MDE skill requested. Probably the fact that some still think that UML is a development method helps.
Another (non-scientific) conclusion from the graph is that the MDE job market is growing very slowly. UML demand has stalled and only MDA (first) and MDD (now) demand has increased a little bit. As much as I like metamodeling it is clear that metamodeling experts have no future in the job market (they could reinvent themselves as DSL experts to have a slightly brighter future) 🙂
