The data will simply get outdated quickly as I strongly suspect most content is immutable once written once, most data mappings are immutable once created once and most application developers do not use RDF aware technologies (why I originally went for XML and not RDF in DwC-A meta definition despite DwC itself being in RDF). </div><div><br></div><div>I complete agree that we need to provide the means to declare (strongly versioned) vocabularies, but I tend to suspect that they should be separated from the content for the most part for better reusability - that was the rationale when I introduced it to the DwC-A. Perhaps it is time to consider a review of the DwC-A meta format though, to play better with (e.g.) SKOS, but I don't think I understand the versioning aspects there - everything seems in constant flux to me.</div><div><br></div><div>Cheers,</div><div>Tim</div><div> </div><div><br></div><br><div><div>On Oct 3, 2013, at 2:25 PM, Hilmar Lapp wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><br><div><div>On Oct 3, 2013, at 6:42 AM, Steve Baskauf wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">I suppose if people want to be unambiguous, they should just use URIs. </blockquote><div><br></div><div>Exactly that.</div><br><blockquote type="cite"> Unfortunately, I'm not aware of URIs for the terms from various systems of describing biomes.</blockquote><div><br></div><div>To the extent that unawareness is to be supported, this can be solved through better documentation.</div><br><blockquote type="cite"> I suppose someone could mint terms if they cared about this. </blockquote><div><br></div><div>Certainly not - minting random terms whose semantic content consists solely of a non-resolving URI string or a string in whatever natural language is barely better than providing no value at all. </div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; ">Or use ENVO uris.</span></blockquote></div><div><br></div><div>Yes, indeed.
