OpenGIS simple feature

Hi,
I'm looking for papers or documents explaining how OpenGIS simple
feature has been adopted in current GIS softwares. or any document
explaining advantages or criticisms about OpenGIS simple feature. I've
found that the only documents available in the web was the
specifications given by OGC, and I found them unclear.
Thanks

All vendors offering Web Services - that is, all major vendors -
support OGC simple features, as these are the basis for web services.
I would suggest that you are asking the wrong question - OGC simple
features are more a statement of a minimum level of feature required
to implement interoperable web services than any thing else. The major
and obvious implementation of them is in GML, the data exchange
language for geographic web services (another OGC and ISO TC211
standard)

I would also suggest that the major area where you should be looking
for support for these features isn't in GI software, but in database
implementations. Oracle Spatial (commercial) and PostGIS (Open-Source)
are probably the best known DBMS implementations of OGC simple
features, but other RDBMS also provide capability - I understand the
MySQL, for example, is moving that way.

Thank you for your answer,
I would like to explain more clearly my question. I'm working in the
field of spatial data integration, and I have adopted OpenGIS data
model (simple feature model) as a basis model for data integration. My
apporach is to translate all data format to a common model (in this
case OpenGIS) and to solve semantic and geometric conflicts encountered
in such data files.

OGC has released OpenGIS simple feature specifications, and many other
texts and reports related to this subject, but I'm still looking for a
framework that could gather all these documents and concepts into a
meaningful manner. Between abstracts, implementations, specifications,
GML (Now I'm not interested in Web component of GIS :WFS, etc), I'm
feeling confused about all these things, and I feel it difficult to
assemble it into a single framework. That's why I'm looking for a
document which has a comprehensive view on this issue.

I am sorry, but I don't think I really understand what you need. If
you have the OGC Simple Features specification, then isn't that all
you need? That is, after all, the definitive documentation, and
anything that is stated elsewhere will simply expand on that - and if
it says something different than it is wrong! If not, then surely you
are venturing into more specific areas, and need to look at more
specific, application specific information. There is quite a good
overview of simple feature geometry in the GML 2 (not GML 3, which
implements a more comprehensive set of features) specification as this
is an implementation of the simple feature specification. You may find
some interest in the ISO TC211 documentation (www.isotc211.org),
giving a different, though related, set of standards which you may
find more organized than the OGC suite - the ISO way of doing things
means that standards tend to be more inter-related.

There are a lot of other standards you need to consider as well, such
as Coordinate Reference Systems, Representation and such like.
