Semantic Web

From LinkedIn Answers
- A book like "A Semantic Web Primer" (Amazon)
- RDF, RDFS, and their representation (RDF/XML, N3)
- At least an intro to DL (see Franconi course), OWL. Which implies Logics
- At least one SW framework (Jena, Sesame)
- SPARQL
- Ontology engineering, how to build ontologies (also some top-level ontologies, like DOLCE)
- Protegé (and maybe SWOOP also)
- Existing ontologies and schemas (e.g.: SKOS, FOAF)
- Good computer science background, good knowledge of Software Engineering (e.g.: UML, Relational model, Web development), some education in AI would be appreciated
- In addition to general knowledge, specialization/experience in some particular application domain (mine is Life Science, which I think is cool, but there are others)
- See also: http://iswc2008.semanticweb.org/tutorials/

-Explorer's Guide to the Semantic Web and Model Driven Architecture and Ontology Development.

ibatis Exception in Initialization Runtime error

If you see a Runtime Exception using Ibatis in the service class, check the path to dao-config.xml file in DAOFactory class. Most likely it is wrong.

Opensource Load Balancing

Got this from an apache mailing list post:

"One (open source) solution would be to use an LVS load balancing server (http://www.linuxvirtualserver.org) to do the load balancing. If you want high availability (no single point of failure in the load balancer) couple LVS with heartbeat (http://www.linux-ha.org), so that if your active load balancer fails, the inactive load balancer takes over.
There is a learning curve with both those technologies, so if you don't have much time (or even if you do), it might be worth a visit to http://www.ultramonkey.org, Simon Horman's project site, in which he supplies prebuilt packages to combine LVS and heartbeat together."
