Hi,
Please, do make it understandable for human beings and start counting numbers
from 1. It is not a big trouble to make computers think in that way too but the
opposite is impossible.

Peter, should startIndex start at 0 or at 1? See also the discussion below.
TIA.

Hi Even,
but if you look at the schema [1], a value of 0 makes more sense to me
(default value is 0 and not 1):
<xsd:attribute name="startIndex" type="xsd:nonNegativeInteger" default="0"/>
[1] http://schemas.opengis.net/wfs/2.0/wfs.xsd
Yes, I agree, but the example in the PDF contradicts that, no ? It is a shame
that there is no clear text saying somehow "Index 0 means first feature".
Who could confirm the "correct" interpretation ?
Best regards,
Bart

Hi,
I read with interest
http://geo-solutions.blogspot.com/2011/12/wfs-for-masses-adding-support-for.html
and decided to play with GeoServer 2.1.3 and its paging support a bit, with
the
OGR WFS driver.
I've tested on the samples (tiger:poi layer) and discovered that GeoServer
takes
as convention that STARTINDEX=0 is the first feature. The issue is that
MapServer 6 took the convention that STARTINDEX=1 is the first feature, and
this
is the convention I used to write the OGR WFS driver.
I decided to read again the WFS 2.0 spec PDF and unfortunately I find it
quite
ambiguous in the spec part, but in the "B.8.4.7 Example 7" section, it
reads :
"""
Find the 5th highest mountain in the region around the Himalayas.
http://www.someserver.com/wfs.cgi?
SERVICE=WFS&
VERSION=2.0.0&
REQUEST=GetFeature&
TYPENAMES=Mountains&
BBOX=27.6669,86.4800,28.2709,87.2120&
SORTBY=Elevation DESC&
STARTINDEX=5&
COUNT=1
"""
which would confirm the interpretation of STARTINDEX=1 for the first
feature,
and STARTINDEX=0.
Any thoughts ?
Best regards,
Even
