From 673c2fa8e710c94b1ce250ec7b01d183d2bf91a0 Mon Sep 17 00:00:00 2001 From: David Robillard Date: Fri, 18 Mar 2011 06:20:40 +0000 Subject: Add OWL types. Fix lv2:minimum, lv2:maximum, and lv2:minimum (definition did not match the reality of their usage) (Spec bug found with Pellet). Move project description metadata to manifest. Remove invalid (non-DL) OWL restrictions, and use of Turtle collection syntax (there is at least one broken implementation in the wild that fails to parse this). LV2 is now almost, but not quite, a valid OWL DL Ontology. --- core.lv2/lv2.ttl | 200 ++++++++++++++++++++++--------------------------------- 1 file changed, 79 insertions(+), 121 deletions(-) (limited to 'core.lv2/lv2.ttl') diff --git a/core.lv2/lv2.ttl b/core.lv2/lv2.ttl index 5b93418..4350f8b 100644 --- a/core.lv2/lv2.ttl +++ b/core.lv2/lv2.ttl @@ -27,15 +27,14 @@ @prefix owl: . @prefix xsd: . @prefix doap: . -@prefix foaf: . #################### ## Resource Class ## #################### -lv2:Resource a rdfs:Class ; +lv2:Resource a rdfs:Class , owl:Class ; rdfs:comment """ -An LV2 Resource (e.g. plugin, specification, or any other LV2 related thing) +An LV2 Resource (e.g. plugin, specification, or any other LV2 related thing).
