[Kde-pim] Nepomuk Local Search Workshop April 2007

[Sebastian Trüg]

Hello guys,

local, i.e. desktop search is an important topic in current development and 
research, not only in the Nepomuk project. Projects like Beagle, Tracker, or 
Strigi and efforts to create a unified interface such as Wasabi show that 
also the open-source community is working on this task. The Nepomuk project 
and more specific Beagle++ aim to even improve the idea of local search as it 
is used at the moment by semantic information based on RDF storage. This not 
only increases the power of the whole desktop search system but also 
increases the complexity of the search problem in general. In addition 
to "simple" text search and pattern matching the semantic information allows 
to exploit relations between resources which raises the need for new search 
interfaces. Since the focus of the Nepomuk project is to establish standard 
interfaces which also includes the local search it is a natural step to 
coordinate this effort with other standardization projects such as Wasabi to 
create one powerful interface and querying language that fulfills the need of 
both the open-source community and the Nepomuk project. This workshop is 
intended to bring the different local search projects and standardization 
effort at one table and coordinate their efforts. The goals of the worksshop 
thus can be summarized as: 

* Create an API for integrated Fulltext and semantic (i.e. RDF) search (based
  on Wasabi)
* Find a good solution for metadata storage and indexing based on RDF. The 
  actual problem here is the combination of a metadata store and a fulltext
  index and how to distribute queries among them.
* Coordinate the way metadata is stored, i.e. artificial resource URIs vs.
  identifiers to make sure data created by the different crawling systems is
  compatible. The biggest part of this problem is already solved by the
  ontologies, however, details may need closer inspection.

On the workshop wiki page [1] you can find a preliminary time table and a list 
of participants. This list reflects whom we would like to attend. Since the 
list does not only contain people from the Nepomuk project we will probably 
have to do the workshop on a weekend. The current proposal is the weekend of 
the 21st and 22nd of April. Please let us know if you will be able to attend. 
We did not fix the date yet and are open for changes in this early state of 
planning.

The workshop will take place at DERI [2] in Galway, Ireland. If you are not 
part of the Nepomuk project and need sponsoring please contact us directly.

Cheers,
Tudor Groza (DERI) and Sebastian Trueg (Edge-IT)
