This set of programs lets you convert MARC subject authority data to SKOS and then serve it up as linked data for use on the semantic web. If you just want to get the triples, and don't want to be bothered with converting legacy MARC data, and running an instance of lcsh.info then you should probably just download the complete set of triples at: http://lcsh.info/static/lcsh.nt Installation instructions: 01. install dependenices: python setup.py install 02. set LCSH_HOME environment variable to the directory that this README file is located 03. copy lcsh.conf.orig to lcsh.conf and edit store location 04. create all the concepts: utils/lcsh2skos.py --create marc.dat 05. create links between concepts: utils/lcsh2skos.py --link marc.dat 07. look up something: utils/concept.py "World Wide Web" 08. download and configure solr with included schema.xml 09. edit lcsh.conf with desired solr server location 10. create fulltext index: utils/index.py 11. start the web server: web/server.py 12. look at http://localhost:8080 in your browser 13. dump out all the data as ntriples: utils/dump.py > lcsh.nt 14. use lighttpd and sample configuration in web/lighttpd.conf to run web application in a production environment
