Hi Alan,

*> What does LOD best practices have to say about biology? *

1) I am a biologist. Most of my work has involved developing computer
technologies to help solve biological questions.

    Yet I have seen this argument used before to support the idea that
biology is so different than all other areas of knowledge that it needs
LSIDS rather than LOD URI's.

I am concerned that people who are thinking of creating ontologies for the

I agree which is why I originally suggested creating some sort of HAO to
LOD mapping ontology. At the time you disagreed with me (see thread)

This idea was based on the paper Juan had recommended. It seems that there
have been some changes to OBO since that was written.

This is the public lod list and they do have best practices documentation,
starting with TBL's 4 things.

By this I mean if all the related entities are OBO than stay in the OBO
world.

Yes if they followed LOD best practices.

This issue is of a ontology designed for one use case but marketed as a
solution to another. I am aware of other uses which is why I was somewhat
puzzled that there seemed to be no examples of SPARQL queries that would
demonstrate how the authors intended for these to be used. They may exist
but I have not found them.

It was while I was exploring creating such examples that I realized that
the ontology does not follow LOD best practices. It was not my intent to
call out this one ontology
but you asked for specific examples. I suspect the mosquito anatomy
ontology has similar issues.

Do people really think that when the Beetle people start on their

Again that is fine if their intent is to stay within the OBO world.

What I have realized is that there are edges between the OBO world and the
LOD world.

Distinctions that are not apparent to many people who intend to
participating in the LOD world.

I think you have turned the situation around. You are on the public_lod
list, perhaps you can better explain what is wrong with the LOD best
practices and why OBO people believe they are unnecessary, or seem
unfamiliar with them?

If there is no intention of using the HAO ontology in the LOD world then
these concerns are moot.

My concern has always been that people who don't completely understand the
distinction between OBO and LOD OWL are being led to believe that they
should base their new LOD projects on the OBO way of doing things rather
than following LOD best practices. In other words, they assume that if they
create their ontology in OBO it will automatically follow LOD best
practices. I believe this was the assumption made by the authors of the HAO
ontology.

For instance, if the EoL.org were to get into creating ontologies with the
intent of participating in the the LOD cloud should those ontologies be
based on LOD best practices or  OBO best practices?
