This specification defines various properties to represent useful information about LV2 hosts. Currently, the primary use of this specification is to describe which extensions are supported by a given host.

The extensions supported by a host can be described like this:

@prefix hi: <http://lv2plug.in/ns/ext/host-info#> .

<http://example.org/some-host>
    a hi:Host ;
    doap:name "Foo Rack" ;
    hi:supportsExtension [
        hi:extension <http://example.org/some-extension> ;
        hi:sinceVersion "1.2.0"
