All,
I analyzed some past threads and teased out and summarized three distinct
modeling issues.
1. Overloading OWL
sameAs<http://ontologydesignpatterns.org/wiki/Community:Overloading_OWL_sameAs>:
sameAs is being used in the linked data community in a way that is
inconsistent with its semantics
2. Proliferation of URIs, Managing
Coreference<http://ontologydesignpatterns.org/wiki/Community:Proliferation_of_URIs%2C_Managing_Coreference>:
How to avoid or manage two negative consequences to the current
proliferation of new URIs being minted for the same things. Specifically:
1. it is hard to find when two things should be the same
2. even if you can find the links, prolific use of owl:sameAs will
create computational problems.
3. Versioning and
URIs<http://ontologydesignpatterns.org/wiki/Community:Versioning_and_URIs>:
When and whether to make new URIs for different versions of things.
I added them to the Catalog of Modeling
Issues<http://ontologydesignpatterns.org/wiki/Community:Main>in the
Ontology
Design Pattern Wiki <http://ontologydesignpatterns.org/wiki>. Click on the

Below is a bit of background on the history of this discussion.

PS The individuals in the CC: of this email were directly involved in the
original discussions.
*Background:*
In May 2008, I kicked off a discussion with the subject "A Semantic
Elephant" describing the unnecessary and costly proliferation of URIs and
owl:sameAs links. This discussion evolved to be mostly about managing
co-reference. Intitially private, this discussion was moved to the W3C
Semantic Web Discussion
List<http://lists.w3.org/Archives/Public/semantic-web/>at Tim
Berners-Lee's request. See: Managing
Co-reference (Was: A Semantic
Elephant?)<http://lists.w3.org/Archives/Public/semantic-web/2008May/0081.html>.
The original discussion also evolved into a discussion about owl:sameAs per
se, which has been a recurring topic on various lists over the years. Aldo
Gangemi provided a concise summary on May 16,
2008<http://lists.w3.org/Archives/Public/semantic-web/2008May/0126.html>.
In October 2008, I started a closely related discussion focused more on
challenges with Versioning and URIs. It was under the subject: URIs and
Unique IDs<http://lists.w3.org/Archives/Public/semantic-web/2008Oct/0192.html>.
>From all this, I teased out the three distinct but closely related modeling
isssues listed above. For each I created a detailed summary of the issues
and topics that were discussed
