Oops!   Fortunately, this is an IAU error, not mine (though you'd  
think I might have caught it).  I replaced the BT with a RT  
radio_frequencies.

Yup - forgot the # all right.   Corrected: now looks like

	<skos:Concept rdf:about="#53_Persei_stars">
		<skos:inScheme rdf:resource=""/>
		<skos:prefLabel>53 Persei stars</skos:prefLabel>
		<skos:broader rdf:resource="#B_stars"/>
		<skos:broader rdf:resource="#pulsating_variable_stars"/>
		<skos:definition>53 Persei stars</skos:definition>
	</skos:Concept>

Got those too.   In the meanwhile, I've found various capitalization  
errors and stuck in some missing stuff for galaxy rotation curves  
(e.g. "Navarro-Frenk-White_profiles" anybody?).

Thanks for the corrections.   Please keep them coming so that we can  
get this finished as a reasonable and reasonably complete (for our  
intial purposes only, of course) suggestion.

Douglas implicitly raises a good point: the text file isn't much  
simpler than n3 and n3 is a lot less verbose than SKOS/OWL - should  
the IVOA suggest vocabularies are published in n3?
