Assume I use jxapi to download an extract of the main OSM database . Is
the
downloaded extract a "Derivative Database", or since the download was
provided by OSM does the downloaded data qualify as simply a "Database"?
Does not ยง4.4b answer this[1]?
Without wishing to state the obvious, if I thought 4.4b answered my
question, then I wouldn't have asked the question on this list.
I understood that if I was the one who carried out the extraction then the
database created would be a derivative database, but it wasn't clear to me
whether if the "Extraction or Re-utilisation of the whole or a Substantial
part" was carried out by the licence holder (ie OSMF) whether this simply
created a new database, rather than a derivative.

" b. For the avoidance of doubt, Extraction or Re-utilisation of
the whole or a Substantial part of the Contents into a new database is
a Derivative Database and must comply with Section 4.4."
As a practical matter, we almost always deal with the OSM db in terms
of a smaller extraction. We create tiles for a few blocks with many
object types, or tiles with only country boundaries and oceans
covering the whole planet. "Planet" files and planet history files
are probably the most frequent use that considers the complete db at
one time. So it might be a derivative database of OSM, but it seems
indistinguishable from "the OSM database broken into a manageable
chunk" ;-)
Why? Do you have a specific use in mind?
I'm just trying to become familiar with the new terminology we are likely
soon to be dealing with.
