http download links missing on some datasets on registry #108

HTTP download link not available on geogratis but is available on certain records in the registry

It's hard to say why this is the case, because two links, both PDF and GeoScan were obtained from the NAP metadata file resource listings. Two possible reasons: Geoscan file has been filtered out at Geogratis, or there is a bug in the Geogratis site. Will investigate further.

Just noticed that while both resources are available in the .nap files, only the PDF file is listed in the atom file.

http://geogratis.gc.ca/api/en/nrcan-rncan/ess-sst/af4e99f3-47b0-59cb-b846-60ae95dd2ca7.atom vs. http://geogratis.gc.ca/api/en/nrcan-rncan/ess-sst/af4e99f3-47b0-59cb-b846-60ae95dd2ca7.nap

Nap includes these elements:

<gmd:onlineResource>
                          <gmd:CI_OnlineResource>
                             <gmd:linkage>

                          </gmd:CI_OnlineResource>

And here is the ATOM which is clearly different:
