A vim script syntax highlighting definition for the Sparqlification Mapping Language (SML). See http://sml.aksw.org for more details.
If you're using vim (on Unix-like systems), there should be a .vim/ directory in your home directory. To use the SML syntax highlighting script you have to copy the sml.vim file (or clone this repository) to ~/.vim/syntax/. Maybe you have to create the syntax directory first. To connect this syntax highlighting definitions with SML files, you have to add the following lines to your ~/.vimrc file:
au BufNewFile,BufRead *.sparqlify setfiletype sml
au BufNewFile,BufRead *.sml setfiletype sml
Now, if you open SML files (having the recommended filename suffixes *.sml or *.sparqlify) they should be syntax highlighted.
