That is understood, but the key issue for some adopters seems to be • ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original. If you develop a commercial product or specificiation that builds upon schema.org, thus binds you to release the result under a Creative Commons Attribution-ShareAlike license, too. The question is what "remix, transform, or build upon the material" means. For instance, if you add schema.org markup to your HTML, does that mean that your whole HTML page must be released the under a Creative Commons Attribution-ShareAlike license? There are potential implications that are problematic for adopters of schema.org. This is why GoodRelations uses the broader Creative Commons Attribution 3.0 license, which just requires attribution.

I believe it's related to what Melvin is asking as his use case is also an 'other than publishing' issue.
