5.4 OWL:QUOTE

We expect that future developers will build language extensions based on OWL. Some of them will want to extend OWL to systems that can state implications (IF a THEN b), modal properties (EVENTUALLY, ALWAYS), attributions (The book states that the earth is 6000 years old), and similar contextually restricted propositions.

There are a number of ways to build such extensions. One is to embed fragments of OWL in the new language. Alternatively, OWL could provide a minimal level of support for extensions by defining a mechanism for scoping OWL expressions that will remain semantically uninterpreted. OWL could provide the 'OWL:QUOTE' tag or attribute to mark such expressions. The key requirement is that the OWL semantics ensure that the content identified by this tag, while OWL notation, has no semantic interpretation in this context.
