Extract triples from RDFa in XHTML documents using Clojure
RDFa extraction in Clojure
This is an implementation in Clojure for parsing RDFa 1.1 embedded in HTML, XHTML, SVG or other XML.
Usage
This library runs on the JVM through regular Clojure. It can also run in a JavaScript environment (eg. any modern browser or Node.js) by using ClojureScript.
On the JVM, it uses the standard Java DOM for parsing XML, and the CyberNeko HTML Parser for HTML.
From Clojure
Example usage from Clojure can be seen in src/rdfa/cli.clj.
Command Line
Build a jar and just use that:
$ lein uberjar
$ java -jar rdfa-*-standalone.jar examples/test.html
Web Interface
For a simple web interface, see clj-rdfa-web.
From Java
- To use with Jena, see clj-rdfa-jena.
- To use with Sesame, see clj-rdfa-sesame.
From JavaScript
Projects written in ClojureScript can use clj-rdfa by adding it as a dependency.
A cljs-based example project using clj-rdfa can be seen in examples/cljs-usage/.
Development
This is about developing the library itself.
Keep a test watcher running with:
$ lein midje --lazytest
In a REPL, run:
user=> (do (use 'rdfa.cli :reload-all) (-main "examples/test.html"))
For interactive development, use e.g.:
$ lein run -m vimclojure.nailgun.NGServer 127.0.0.1
