Re: Is it best practices to use a rdfs:seeAlso link to a potentially multimegabyte PDF?, existing predicate for linking to PDF?

It is well to look at and make best practices for the things
we have if we don't

It was the FOAF folks who, initially, instead of using linked data,
used an Inverse Functional Property to uniquely identify 
someone and then rdfs:seeAlso to find the data about them.
So any FOAF browser has to look up the seeAlso  or they 
don't follow any links.

So tabulator always when looking up x and finding x see:also y will 
load y.  So must any similar client or any crawler.

So there is a lot of existing use we would throw away if we 
allowed rdfs:seeAlso for pointing to things which do not 
provide data. (It isn't the question of conneg or mime type,
that is a red herring. it is whether there is machine-redable
standards-based stuff about x).

Further, we should not make any weaker properties like seeDocumentation
subproperties of see:Also, or they would imply
We maybe need a very weak top property like


to be the superProperty of all the others.

One things which could be stronger than seeAlso is definedBy if it
is normally used for data, to point to the definitive ontology.
That would then imply seeAlso.
