## Template Apache .htaccess file for serving vocabularies.
## This file is configured at make time, with the following
## substitutions:
##
##     @BASE@ should be the path component of the base URI of the
##     vocabulary distribution, that is, without the protocol and
##     authority components. 
##
##    @SUBDIR@ is a versioned subdirectory, where the public URIs
##    redirect to.  This is not an advertised directory, but it needs
##    to be generally accessible.
##
##    @FILEOPTS@ is a list of the supported vocabulary names,
##    separated by vertical bars.  For example 'AOIM|AAkeys'.  This
##     lists the vocabularies which this file will actually serve.
##
## This file is patterned after Recipe 3 in the W3C document 'Best
## Practice Recipes for Publishing RDF Vocabularies', at
## <http://www.w3.org/TR/swbp-vocab-pub/>
