If there is anything that this forum is good for, it is re-thinking. (01)
If someone already has an open repository where the metadata about an
ontology can be uploaded by anyone who wants to and the community can
post comments and create links between ontologies, then lets all support
If it does not exist, lets make it.
It is easy to make and if the community wants to work on it, it is easy
to maintain. If the community does not , then it will fall into disuse.
No biggie. (02)
The nice thing about a wiki is that it is unstructured and open. This
also has some downsides; it is unstructured and open. (03)
Wikipedia has done a great service with its unstructured and open
encyclopedia but it has not eliminated peer-reviewed journals or
databases. This wiki would not either. (04)
1) Does it already exist and can we all contribute?
2) If we made a new one, who would be interested in using it?
3) What is the minimum metadata for an ontology (URL, Ownership,
License, Subject areas, number of terms, last update date.)?
4) What are the extra data that one would like to see (List of
applications using it, list of reviews, list of compatible ontologies,
list of alternative ontologies..)? (05)
