Yes, you are correct. Many of my URI patterns are of this format.
Changing them such at they do not overlap, fixed the "Unsupported
NUMERIC format" problem.
However, it did not remove the malformed triples in the dump, which came
from two tables/classmap:
1) ...wellbore/1004/test/drillstem/4.1E0
2)
...wellbore/100/document/100%5F07%5F31%5F3%5F2%5FBorehole%5Fgeoph.well%5FGeophone%5Fencl%5F1.pdf
which in decoded form is
...wellbore/100/document/100_07_31_3_2_Borehole_geoph.well_Geophone_encl_1.pdf
I have come up with solutions for both problems:
The problem with 1) was that the value 4.1E0 is stored in a FLOAT
datatype. The SELECT query for this resource uses equality in the WHERE
clause to get the correct row, and this fails, since comparing FLOATs
this way is not a good idea:
... WHERE (`wellbore_dst`.`wlbDstTestNumber` = 3.3 ...
Changing the DB datatype to DECIMAL fixed the problem.
BTW, the decimal value 4.1 is exported as 4.1E0. I would prefer that the
exported value was 4.1. Is there a way to achieve this?
The problem with 2) is, I think, that the filename part of the URL
(100_07_31_3_2_Borehole_geoph.well_Geophone_encl_1) is de-urlified (in
the map the url pattern is urlified with |urlify), but the filename
contained underscores prior to urlification, so de-urlification removes
too many underscores. Replacing |urlify with |urlencode fixed the problem.

Will do!
Thanks,
