Hello again,<br>
<br>
for one more use case I would like to get your oppinion regarding
the ODbL. Your answers are relevant for our research, and could be
relevant for Muki Haklay and others who compare OSM with other
reference datasets to analyse the quality, like completeness of
objects and thematic attributes, locational precision, correctness
of thematic attributes. <br>
<br>
<p class="MsoNormal"><span style="mso-ansi-language:EN-US"
lang="EN-US">Use case "Publication on the quality of
OpenStreetMap relative to a reference set"</span></p>
<p class="MsoNormal"><span style="mso-ansi-language:EN-US"
lang="EN-US">A publication assesses the quality of the OSM road
network by matching the OSM objects with those of another road
network, the reference set, and then compares the matching
objects. The document contains a thematic OSM map, where the
style (colour, breadth, …) of the OSM roads visualizes a
compared quality.<span style="mso-spacerun:yes"> </span>The
publication could also contain charts and other maps where the
quality is displayed on grid cells. </span></p>
<p class="MsoNormal"><span style="" lang="EN-US">Is it correct that
only the thematic map with OSM road objects is a produced work?
So only the small table containing the identifiers of the
visible OSM road objects and their quality is a derivative
database? And is this table insubstantial<span
style="mso-spacerun:yes"> </span>so that it need not be
provided under ODbL? <br>
In particular, underlying our publication is a much bigger table
that contains a matching between the identifiers of the two road
networks, as well as their attributes, which are to be compared,
e.g. road category, name, speed limit, oneway, pedestrian? Is it
true that this table need not provided together with the
publication?<br>
</span></p>
<p class="MsoNormal"><span style="" lang="EN-US">Once more, thank
you for your comments,<br>
</span></p>
