Hello Timothy,
thanks for sharing your concerns and doubts :)
On top of what Dimitris already explained I would like to add the following:
1) COSPAR property URI is actually
http://dbpedia.org/ontology/cosparId(there was a typo in the
previously shared URI)
2) cosparId property is currently used in other mappings (
http://mappings.dbpedia.org/index.php/Special:WhatLinksHere/OntologyProperty:CosparId
).
One of those, namely
http://mappings.dbpedia.org/index.php/Mapping_en:Infobox_Year_in_spaceflight,
is using it in an "incorrect" way, i.e. using the COSPAR id for the number
of catalogued orbital launches in a specific year. As Dimitris said, the
cosparId property range must be changed from xsd:integer to xsd:string.
Would you like to make those changes?
Feel free to ask any other question here on the mailinglist :)
Cheers
Andrea
