Matthias, Michael,
I think this is a great idea and I would really like to see some
connections emerge between the HCLS web of data and the LOD web of
data. If I can be of any help with some LOD and DBpedia expertise,
just let me know.
Cheers,
Richard

Here is the text that can also be found and edited on the Wiki page:
___HCLS KB mapping to the open linked data repositories___
It would be great if two of the largest coherent Semantic Web
structures, namely the HCLS Knowledge Base and the Linking Open Data
datasets [2], could be mapped to each other.
Some possible anchors in the Linking Open Data (LOD) datasets:
* DBpedia (besides label-matching, we could also make use of
information like CAS number, Uniprot/Pubmed references etc. that are
part of DBpedia)
* YAGO
* W3C Wordnet
* OpenCyc 1.0
Some possible anchors in the HCLS KB:
* All of the OBO ontologies
* MeSH in SKOS
* NeuronDB
Since DBpedia is already mapped to most other datasets in the LOD
collection, DBpedia would probably be our primary target for such
mappings. Since the ontological foundation of most LOD datasets is
relatively loose compared to most HCLS datasets, the mapping should
not be done with owl:sameAs or owl:equivalentClass statements, but
rather with softer statements such as rdfs:seeAlso. The only
exception is OpenCyc, where a more stringent mapping with
owl:equivalentClass is possible. A mapping between the SKOS version
of MeSH and the SKOS version of Wikipedia categories could also
receive special attention: we could use owl:sameAs (although this is
discouraged by the SKOS specification) or the specialized SKOS
mapping vocabulary.
Furthermore, we should:
* Learn about the guidelines for publishing RDF/OWL according to the
practices agreed on by the Open Linked Data community [3]
* Analyze which of the HCLS KB datasets are already in agreement
with these practices
* Decide if some of our HCLS-oriented projects could benefit from
adhering to these practices. This should NOT trigger a general
discussion about URI issues and resolution mechanisms once again. At
this point, we simply want to evaluate who in the HCLS community it
motivated to published 'linked data'.
Even if we decide that adhering to the linked data practices is not
of special interest to us, a mapping to the LOD datasets would still
be very valuable in itself.

Subject: BioRDF Brainstorming
I've created a Wiki page where people can propose projects for
BioRDF to
work on until the end of April [1]. It'd be great if you could post
any
ideas that you may have.
Cheers,
