Issue-8 asks for property chains that end with data properties. Adding this construct to OWL 1.1 would compromise decidability. This feature would automatically be in an OWL Full version because in OWL Full data properties are also object properties. Later discussion asked whether having data properties in the middle of a chain can be done. In OWL 1.1 such chains would have an empty extension, and thus be useless. The situation in OWL Full is the same as for data properties at the end of a chain. I therefore propose that we CLOSE ISSUE-8 (even though it is not even OPEN) without doing anything on the twin grounds that it both compromises decidability in OWL 1.1 and is not handled by tools, and that there is nothing special that needs to be done in OWL Full. Peter F. Patel-Schneider Bell Labs Research PS: I'm proposing handling ISSUE-8 in this manner as is it is closely related to ISSUE-83.
