update of interaction types

Can you please have a look at this code and tell me if we can/should update this:

	private static Resource getLineTypeResource(LineType lt) {
		if(lt.equals(LineType.ARROW)) {
			return null;
		} else if (lt.equals(LineType.TBAR)) {
			return Wp.Inhibition;
		} else if (lt.equals(MIMShapes.MIM_CATALYSIS)) {
			return Wp.Catalysis;
		} else if (lt.equals(MIMShapes.MIM_CONVERSION)) {
			return Wp.Conversion;
		} else if (lt.equals(MIMShapes.MIM_INHIBITION)) {
			return Wp.Inhibition;
		} else if (lt.equals(MIMShapes.MIM_STIMULATION)) {
			return Wp.Stimulation;
		} else if (lt.equals(MIMShapes.MIM_TRANSLATION)) {
			return Wp.TranscriptionTranslation;
		} else if (lt.equals(MIMShapes.MIM_NECESSARY_STIMULATION)) {
			System.out.println("TODO: necessary stimulation");
		} else if (lt.equals(MIMShapes.MIM_MODIFICATION)) {
			System.out.println("TODO: modification");
		} else {
			System.out.println("Unknown and unsupported interaction type: " + lt);
		}
		return null;
	}

I think we might have to. This is what I find in the output of the RDF generation

778x "Unknown and unsupported interaction type: mim-binding"
30x "Unknown and unsupported interaction type: mim-cleavage"
9x "Unknown and unsupported interaction type: ReceptorSquare"
6x "Unknown and unsupported interaction type: Receptor"
