An aside: I think I understand the points, and emphases you're trying to make here, but I'd like to discourage thinking of .../4.14#E1 as being deeply different from .../4.14.E1. The former is simply the latter "in context". And please leave off the ".html" [The rationale is somewhat more mundane than the discussion here, but I think worthwhile. We're trying to maximize the usefulness of links, permalinks, bookmarks, content negotiaion, electronic vs paper cross-referencing.] > Exactly, just that I chose different URIs above.

I don't know that I intentionally suggested that, or followed someone elses suggestion, but if such a URL were to become valid in the near term, it would probably just be a restatement of the informal notion of 4.14.E1 "defining" sine. That is, http://dlmf.nist.gov/#sin would (currently) redirect to http://dlmf.nist.gov/4.14.E1 which would redirect to http://dlmf.nist.gov/4.14#E1 I would imagine that it is valid for the 1st and 2nd URI's in that list can reasonably be taken as _identifying_ distinct things (a definition of sine vs an equation, respectively). The practicalities of a working web server could be confusing however. Whether DLMF should provide an explicit URL indicating "sine itself", or it's definition ... or whether we should even think of ourselves as defining sine... is something this discussion can help answer. _______________________________________________ Om mailing list [email protected] http://openmath.org/mailman/listinfo/om
