Hi Kingsley,
Thank you for the pointer. It is right Umbel provides a way to link
vocabularies. There are others (e.g. SKOS, the alignment format).
We will look at how what we try to do can complement Umbel and build
on it instead of competing with it.
Our experiment is actually focused on link-generator specifications,
many exist and we would like to look at them and see how they could be
published.
Yes, the key thing is that this task isn't instance data only (abox) you
need tbox smarts and thats basically the kind of substrate UMBEL
provides. Note, UMBEL and SKOS aren't mutually exclusive :-)

Cheers !

Dear LODers,
There has been a couple of discussions already on this list on the need
for a vocabulary to represent correspondences between terms of
different
vocabularies. We also saw recently various tools (e.g. Silk, ODDlinker)
allowing to automatically interlink datasets given a specification of
what should be linked.
However, there is currently no common way to publish and share this
information (i.e., not the links but the way to generate them, see [1]
for precision).
We are setting up an experiment [1] to see if it is possible to provide
useful services from this data. But for that purpose we need your help.
So this is a call for contribution: we are collecting any specification
of link generator for the LOD graph.
Of course, do not hesitate to comment on the idea or to tell us if you
want to be involved.
We promise a report on this by the end of summer (northern
hemisphere :).
Cheers,
François

Francois,
With regards to the question [1]: did I miss something? How about
UMBEL[2] ? An effort that was created to address these kinds of
issues eons ago.
I remain quite confused about the tendency to open up new patches
when existing efforts (of the community variety) are already in
place. Recreation from scratch doesn't scale. Rememer, Microsoft came
to prominence buy groking a basic principle: Embrace and Extend.
Alignment across Vocabularies, Schemas, or Ontologies is what UMBEL
is/was about.
