The following was originally a submission by the author to the W3C OWL working group. As the group chose not to include this in their recommendation work (deciding instead to have an OWL profile with far more in it), and as I remain the last (and only) person to edit the content below (others made changes on the wiki page on which it appeared) I see nothing in the submission rules to the RDF Next Steps workshop to prohibit its submission. I have added a title and authorship, and made some minor changes to the original content to make it self-contained outside of the Working Group context.
I believe an important RDF user group is the Web 3.0 Application Developer, who is willing to use a small amount of OWL if it helps, does not often have a classfication/realization problem so are not using DL reasoners, and care about scaling from a computational (rather than formal) view - i.e. being able to do map/reduce parallelism on the feature set would be a valuable plus.
One name that has been suggested for this is "RDFS 3.0" as it would be the third update of RDFS and it would resonate with being a language of use to the "Web 3.0" developer community.
The following subset of language terms, similar to those included in Oracle's OWL Prime, is the suggested starting place. Specifically we could extend RDFS with:
Some people have suggested we include class relationships - intersection, union and complement - but only for named classes. I leave this as a matter of discussion.
