Interlinking information for the HyperSpec
Imagine you're looking at a glossary entry. It's normative, but to which areas of the spec is it relevant? Which functions depend on its definition? I often asked myself that, and it bothered me enough that I wrote this program to extract the hyperlinking structure from the CLHS into an RDF graph, which can be imported into any database (of course, I recommend agraph) that can answer these types of questions.
= Creating the triple information
- Install the dependencies:
- Load the clsem.asd,
(asdf:oos 'asdf:load-op :clsem)
This will query the lispworks HTTP servers and will take a long, long time. If you have a copy of the HyperSpec downloaded, you can use:
(clsem:do-it #p"/path/to/output/file.ttl" :prefix "file:///Users/asf/Downloads/HyperSpec-7-0/HyperSpec")
And it will finish in ~9 seconds.
This file is in the turtle RDF triple language format. If you import the data into a graph database, things may be easier if you convert it to the ntriples format first. I recommend using the most excellent rapper for this task.
