My name is Sergey Shernyshev and I'm running TechPresentations.org
project using Semantic MediaWiki (SMW).
Currently I'm thinking about making the dataset more open and want to
connect it to LOD through presentation topics that I recently
introduced into the project.
I wonder if someone can give me any recomendations about going open?
I see two major parts here:
1. Using some open vocabulary for describing the data. The question
here is how do I find a vocabulary? The only one relatively close to
TechPresentations is http://www.w3.org/2004/08/Presentations.owl
(thanks to Ivan Herman for this!), but it's definitely geared towards
w3c's activities and I don't know if there is anything else beyond
that on the market, will appreciate any thoughts and suggestions.
I think that FOAF, the Dublin Core Terms, and the SWRC ontology should
provide you with a fairly complete collection of the required terms.
If you can't find anything that fits your needs, don't hesitate to
create your own classes and properties, you can always add superclass
relationships to existing terms later.
2. Connecting to LOD dataset. Being quite new to the project, I have
very vague idea of the process and will be happy to get a pointer to
some documentation about it. SMW is a great tool and I'll be happy to
work with it's development team to incorporate all the best practices
that will make all SMW-powered sites a potential source for LOD data,
I just need to get better understanding of the requirements.
Right now I'm just working on adding "Equivalent URI" SMW special
property to pages which get translated to "owl:sameAs" on RDF export
- you can see an example of the page here:
http://www.techpresentations.org/MySQL (factbox at the bottom links
to DBPedia's http://dbpedia.org/resource/MySQL) and
http://www.techpresentations.org/Special:ExportRDF/MySQL - RDF export
for the page (you can see <owl:sameAs
rdf:resource="http://dbpedia.org/resource/MySQL"/> being added).
Some potential interlinking opportunities:
- owl:sameAs to DBpedia for topics covered in TechPresentations.org,
as you already do
- foaf:homepage links for people (if known)
- owl:sameAs links to FOAF profiles of people (if known)
- OntoWorld.org seems to cover some of the same ground and already has
URIs for many people, conferences and so on
- The L3S DBLP server already has URIs for many people and the papers
that might be associated with the talks
I also have some ideas on how SMW and it's extensions (Semantic
Forms, Semantic Drilldown and some visualization extensions like
Semantic Google Maps and etc.) can be useful for LOD project, for
example, it can be used as publicly open editor for interconnections
between various datasets.
Interesting. There is some (still very early) existing work about
open, collaborative interlinking here:

Richard,
Who is behind: http://143.224.254.32/irs/ ?
I ask because I note that it doesn't attempt discern owl:sameAs links
from input URIs. For instance, I have a lot of owl:sameAs links that can
be discerned via any of my data space uris:
1. http://myopenlink.net/dataspace/person/kidehen#this
2. http://community.linkeddata.org/dataspace/person/kidehen2#this
3. http://kidehen.idehen.net/dataspace/person/kidehen#this
The system should ask me to confirm the owl:sameAs claims rather than
make me type them in all over again, is my key point.

I'll be happy to discuss them with the community if there is interest
in this technology.
Thank you,
Sergey
