Re: Any reason for ontology reuse?

Simple rules:

1. It is better to use an existing ontology than inventing your own.
2. It is better to use the most popular existing ontology than a less  
popular existing ontology.
3. It is better to publish your data using your own ontology than not  
publishing your data at all.
4. It is better to use a good (*) private ontology for publishing your  
data than using a messy private ontology.

(*) A good ontology is one that preserves the largest share of the  
original conceptual distinctions in your data, i.e. it does not  
require merging entity types that are distinct in the original data,  
as long as this distinction matters for potential data consumers.

Whether option #1 is feasible depends on

1. how much time and money you are willing into lifting / publishing  
your data (that will be a matter of economic incentives).
2. how complicated it is to populate that ontology based on the  
available data and the local schemas.
