Re: [biordf] Progress with PDSP Ki database

Well done, Matthias.

As the number of semantic web resources (e.g., owl ontologies) is 
increasing, the next step is to develop intuitive user interface that 
will exploit and integrate these ontologies without requiring the users 
(e.g., neuroscientists) to learn SPARQL and/or a specific OWL-based 
query language. To this end, the SenseLab team (including Matthias) in 
collaboration with the CCDB team has developed a prototype interface 
called "Entrez Neuron" (http://ycmi.med.yale.edu/entrez_neuron.html), 
which allows users to query across several neuroscience ontologies 
(NeuronDB, ModelDB, and CCDB) using keywords. These ontologies are 
currently stored in Oracle RDF Data Model (Oracle 10g). We are planning 
to migrate to Oracle 11g, which supports OWL. In addition, we plan to 
incorporate more neuroscience-related sources as well as expand the 
interface/querying capabilities in the future. Entrez Neuron is still 
under active development. Feedback and suggestions are welcome.

Cheers,

-Kei
