[esip-semantictech] Ontology portal recommendati

Mon May 23 13:58:00 EDT 2016

Hi Lewis,

I hadn’t forgotten that.  That may resolve the identifier issue (at least in the short term - maybe) but not the question of where should the ontologies live and be curated from for the long term and how does the field guarantee long-term access?

Copies of my ontologies are both on github which is where Google migrated them when they took Google Code down and in the ESIP semantic portal; but what is the real "right solution?  Is github sufficient? If so, then does ESIP need a semantic repository?  Do we need both (the “Lots of Copies Keeps Stuff Safe" concept says probably yes); but who is going to curate these and keep both copies in sync for the long term.  Yes, I can do so now (though unfunded); but that won’t last forever. 

I submit that my experience to date says not to trust any external provider even if they say that they are working to provide long term support.  I mean really, I used Google code to make the ontologies public and I used PURL’s for all the URL’s so that I could redirect the URL’s if the ontologies needed to be moved somewhere else.  The problem is that I no longer can redirect them since OCLC is abandoning PURL.org.   

So this experiment in providing long term access to semantic resources failed because none of the tools lasted longer than 3 years…  That doesn’t give great confidence that the concept of reusable semantic resources has a chance of ever happening in the Earth sciences.

And if you think this sounds a lot like the research data problem, well you are right it absolutely does!
