Hi-- Is there any existing code that can validate the descriptive metadata of an OpenURL ContextObject? For example, http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:journal states thats "auinit1" can have zero or one value and it must be the first author's first initial. Is there something into which I can input an OpenURL to see whether indeed the auinit1 param value is only one character (either A-Z or a-z) and has no more than one occurrence... plus all the other constraints for the other parameters in the Matrix on http://www.openurl.info/registry/docs/mtx/info:ofi/fmt:kev:mtx:journal ? --SET
