Welcome to the list!

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:

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