<div class="">There was discussion in February, 2016 with this summary by Sean Gillies:</div>
<div class="">- A Feature or Geometry object MUST NOT contain a "features" property.<br class="">
- A FeatureCollection or Geometry object MUST NOT contain a "geometry" or "properties" object.<br class="">
- A FeatureCollection or Feature object MUST NOT contain a "coordinates" property.</div>

<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Followed by some remorse by Martin Daly:</div>
<div class="">I'm feeling bad now that we've banned FeatureCollection from having a "properties" member, but not bad enough to stand in the way of progress.</div>
<div class=""><a href="https://github.com/geojson/draft-geojson/pull/142#issuecomment-185834388" class="">https://github.com/geojson/draft-geojson/pull/142#issuecomment-185834388</a></div>
<div class=""><br class="">

<div class=""><br class="">
</div>
<div class="">In any case, based on 6.1, any foreign member would be precluded from having GeoJSON semantics. So using "properties" as a member of a FeatureCollection would not be the same as "properties" in, say, a Feature. (Of course, since there's no real
semantic definition of "properties", that point is moot).</div>
<div class=""><br class="">
</div>
<div class="">So, if you were working on something that seems to want properties on a FeatureCollection, it would be better to give it a different name.</div>
<div class=""><br class="">
</div>
<div class="">Getting back to the RFC document, my reading of the last sentence of 7.1</div>
<div class=""><br class="">
<div class="">
<div class=""> The GeoJSON "features" member defines a FeatureCollection object.</div>
<div class=""> Feature and Geometry objects, respectively, MUST NOT contain a</div>
<div class=""> "features" member.</div>
<div class=""><br class="">
</div>
<div class="">make sit clear that the word "respectively" is not being used according to its common definition, namely</div>
<div class=""><br class="">
</div>
<div class=""> (of two or more things, with reference to two or more things previously mentioned) referring or applying to in a parallel or sequential way</div>
<div class=""> <a href="http://www.dictionary.com/browse/respectively" class="">http://www.dictionary.com/browse/respectively</a></div>
<div class=""><br class="">
</div>
<div class="">and this calls into question the use of the word in the previous two paragraphs, which leads to the conclusion that the RFC is trying to say that a FeatureCollection MUST NOT contain a "properties" member.</div>

<div class="">Hi Sean and all <br class="">
<br class="">
Regarding the section 7.1 of RFC7946 that says <br class="">
The GeoJSON "geometry" and "properties" members define a Feature<br class="">
object. FeatureCollection and Geometry objects, respectively, MUST<br class="">
NOT contain a "geometry" or "properties" member.<br class="">
<br class="">
My interpretation is that the "respectively “ decomposes the sentence into <br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>* "FeatureCollection" object MUST NOT contain a "geometry" member<br class="">
<span class="Apple-tab-span" style="white-space:pre"></span>* "Geometry" object MUST NOT contain a "properties” member<br class="">
<br class="">
However, I got comments that this sentence could mean that FeatureCollection MUST NOT contain a "properties” member.<br class="">
<br class="">
Can you please confirm the right assumption?<br class="">
<br class="">
<br class="">
thanks and cheers<br class="">
<br class="">
Pedro<br class="">
